Jason Napodano parle d'opportunité, TSRX devrait finir l'année avec plus de 60M en cash, un éventuel partenariat en Europe en 2012

"This may explain the selling pressure in $TSRX:

On January 12, 2012, Sofinnova Venture Partners VII, L.P. distributed 3,615,572 shares of Common Stock without consideration to its partners pro rata pursuant to its partnership agreement and a Rule 10b5-1 Distribution Plan between Sofinnova Venture Partners VII, L.P. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, dated November 29, 2011,
previously filed as an exhibit to Amendment No. 1 to the Schedule 13D (as amended to date, the “Rule 10b5-1 Plan”).

That's a lot of shares given the ADV. Might take a few more days to work through. However, the fundamental story remains in place. I'd use this as an opportunity to get in - if you like the story long-term. "

"$TSRX: So I have no idea why the stock is down. I know that Rib-x (developing 2 p2 MRSA drugs, including radezolid) was in San Fran hosting meetings around #JPM12. I tried to get a meeting with them but they did not respond (lame).

TSRX should report cash of just over $60 million at year end 2011. That's a nice amount, but clearly they are going to need more prior to commercialization. The plan for 2012 is to move into a 3rd p3 trial (under SPA) for lung infections.

Two ways to raise money - do a secondary or do a deal. I think we see both in 2012. The deal will be centered around EU rights to tedizolid. Remember, Bayer took the Asian rights last year. So when/if they do a secondary offering really depends on when/if they do a deal for Europe and how much they get. Like I said, I think we see both this year. I'd recommend owning the stock ahead of an EU deal. It could be fairly sizable.

As for the U.S. rights, I think management keeps them all the way to the market. The goal is to become the next Cubist. And they have a really interesting preclinial pipeline to boot, so I think they keep tedizolid for themselves and then bring the next drug to market (GyrB/ParE) as a follow-up.

I met with CEO, CFO, CCO, CMO, and VP-Dev earlier in the week. Very good meeting. No change to my investment thesis or $10 target. "

bon, je continue mon monologue...

suis tombé par hasard sur une sorte d'article ( du 1er décembre 2011 ) qui présente les éventuels futurs blockbusters ...

pour les antibiotiques, TSRX est cité parmi d'autres candidats...


"Trius Therapeutics, a San Diego-based biopharma, is now in Phase III testing on a next-in-class oxazolidinone called tedizolid phosphate, or TR-701. If approved, Bayer will sell the drug outside the US. "Data [on TR-701] is coming in early 2012, and I'm very confident that it will be positive," says Selvaraju. "There's activity in this drug not only in skin infections, but also in bacterially associated pneumonia, so it's got a broad spectrum of activity, and I think it will become a very nice commercial opportunity for Trius going forward."

non, tu n'es pas tout seul Sasane !

Juste une précision à t'apporter car je suis Trius depuis 2-3 mois déjà : les résultats de la 1ere phase 3 ont été annoncés (fin décembre de mémoire). Ils sont plutôt bons mais n'ont pas emballé les investisseurs. La 2e phase 3 a débuté maiss ses résultats ne sont attendus qu'au Q1 2013 normalement.

Tout ça pour dire qu'il n'y a pas beaucoup d'éléments tirant à la hausse Trius ces prochains mois.

Le seul catalyseur que j'ai noté, c'est la participation à une grande conférence pour présenter plus en détail leur 1ere phase 3 quelque part en 2012 (sans plus de précision malheureusement).

Pour l'instant, je regarde mais je n'entre pas.

tu as peut-être raison, mais un éventuel partenariat pour l'Europe n'est pas à négliger et puis les plus beaux catalyseurs sont sans doute ceux qu'on n'attend pas...

Buying Opportunity In Trius Therapeutics

By Jason Napodano, CFA

On January 12, 2012, Sofinnova Venture Partners VII, L.P. (SVP) distributed 3,615,572 shares of Trius Therapeutics (TSRX / $5.63 / share) common stock without consideration to its partners pro rata pursuant to its partnership agreement and a Rule 10b5-1 Distribution Plan between Sofinnova Venture Partners VII, L.P. and Merrill Lynch, Pierce, Fenner & Smith Incorporated. In the simplest terms, SVP is a venture capital firm that has been with Trius since before they were public. SVP has a previously agreed upon distribution agreement (AKA - an exit plan) for the shares. As a early investor / venture capital firm, SVP executed its business model perfectly with Trius, i.e. get in early for cheap, and then get out after the IPO lock-up period at (significantly) higher prices. From their point of view, it's time to move on.

With an average daily volume of only 150k shares, working through 3.6 million will take some time. That amount of stock hitting the market caused a meaningful sell-off in the shares, down from $7 before the news to a low of $5.25 last week. Volume over the past week has totaled about 3.0 million shares. This leads us to believe the bulk of the SVP shares have been sold, and are now in the hands of new shareholders. SVP owned over 12% of the stock, so the shares being distributed into the active market is a good thing. It should help increase liquidity for new investors.

...Use Pull-Back As Entry Point...

We remain big fans of Trius. Investors that agree should use this pull-bank on "non-fundamentals" as an entry point. We remind investors that On December 19, 2011, Trius Therapeutics announced results from the company’s 1st phase 3 trial (Study-112) studying 200mg once-daily oral tedizolid (TZD) for 6 days versus 600mg twice-daily oral linezolid (Pfizer’s Zyvox) for 10 days in patients with acute bacterial skin and skin structure infections (ABSSSI). The trial was a non-inferiority design (90% power to detect a 10% non-inferiority margin between the two arms). The trial enrolled a total of 667 patients across sites in North America.
The primary endpoint was cessation of lesion spread and resolution of fever at 48-72 hours after initiation of study drug on an intent-to-treat (ITT) analysis. There were also key secondary endpoints, including sustained clinical response at end-of-treatment (EOT) in the ITT and clinically evaluable (CE) populations and an investigator’s assessment of clinical success in the ITT and CE populations.

The data above look very good. We did not expect tedizolid to achieve superiority to linezolid. To achieve superiority, tedizolid drug would have had to have posted a primary endpoint >7% versus linezolid. Truth be told, linezolid is a highly effective drug. Pfizer would not have sold $1.2 billion of Zyvox in 2010 if the drug didn’t work. We note the rates of methicillin-resistance Staphylococcus aureus (MRSA) infection and outcomes were similar between both arms.

We are surprised that the primary outcome was so close, but we note that the primary endpoint is a composite of both cessation of lesions and absence in fever. According to management, tedizolid offers up numerically better results on the cessation of lesions endpoint – approximately 87% vs. 85%. Both drugs lost efficacy points due to missing temperature data. It becomes difficult to prove in a clinical setting the rapid onset of efficacy when clinicians are not always following the exact FDA guidelines with respect for registration of a new drug application. We think these data are consistent with the clinical profile of the drug demonstrated in early trials.

That being said, what did show a positive trend in the favor for tedizolid was the tolerability. Treatment emergent adverse events were higher for linezolid. Gastrointestinal disorders, which include nausea, vomiting, and diarrhea, were statistically significant in favor of tedizolid. Tedizolid also had less of a detrimental effect on platelet count. Besides better tolerability, we noted the significant administrative and convenience advantages of tedizolid versus linezolid, including a shorter course of treatment (6 days vs. 10 days), once-daily dosing, and bioequivalence between the oral and IV dose.

We think the drug can gain market share from linezolid based on these advantages. With the above marketing advantages on safety and convenience and a superior efficacy claim, we think tedizolid could have best-in-class. Based on the top-line data from Study-112, we still think tedizolid will be a very nice drug for Trius. Paramount is that Trius gets the drug on the market before Zyvox loses patent exclusivity in mid-2015.
…Second Phase 3 Ongoing…

We remind investors that Trius is also testing tedizolid is second phase 3 trial, Study-113, also under a U.S. FDA SPA. Stuyd-113 is an IV-to-Oral step-down trial that will compare the efficacy and safety of 200mg QD tedizolid for 6 days to 600mg BID linezolid (Zyvox) for 10 days. All patients will be initiated on IV dosage form for a minimum of one day and be transitioned to the oral dose form at the discretion of the clinical investigator. We note that having both an IV and oral dosage formulation is a key differentiator to Cubist’s Cubicin (daptomycin). We expect data from this program in early 2013.

…Commercial Potential Is Very Attractive…

We see a significant commercial potential for tedizolid in the U.S. If the second phase 3 program goes as we expect, the drug has peak sales in the $300 million to $350 million range in North America. The current market is dominated by vancomycin and linezolid. The therapeutic window on both is closing. Key for Trius is to gain the cleanest and widest label possible. Expanding the indications into HAP/VAP, pneumonia, and bacteremia provide meaningful upside to our forecast.
This is clearly a large market. U.S. sales for Zyvox, Cubicin, Tygacil, and generic vancomycin eclipsed $1.5 billion in 2010. Vancomycin prescriptions grew by 6% CAGR between 2005 and 2010. Yet, despite the presence of generic vancomycin, branded sales of Zyvox, Cubicin, and Tygacil grew by 20% CAGR. The market is shifting to more effective drugs, and price is becoming less of a factor.

In fact, initial market research conducted by management on formulary acceptance shows that with a non-inferior profile to Zyvox, tedizolid will see broad (~90%) Tier-2 coverage at parity pricing per course of treatment (roughly $1,500) to Zyvox. This includes a range of indications, including skin, HAP/VAP, Bacteremia, and MRSA.

The Trius R&D day in December 2011 offered perspective from two leading physicians with significant experience in treating patients with MRSA: Dr. Ralph Corey, Profession or Medicine and Infectious disease at Duke University and Dr. Jeff Kingsley, CEO of the Southeast Regional Research Group. Both doctors concluded that despite the availability of generic vancomycin and expensive branded products such as Zyvox, Cubicin, and Tygacil, a void remained in the market for a highly effective drug that met all the requirements for success.
Based on data above from the first phase 3 trial and non-clinical history of tedizolid, we see the drug is poised to be “Best-in-Class” with a full label. We are expecting a new drug application (NDA) around the middle of 2013, with FDA approval in 2014. Additional applications for HAP/VAP, pneumonia, and bacteremia should follow in 2014 and beyond. The biggest near-term catalyst for the shares is a deal for the European market, perhaps in 2012. We remind investors that Bayer licensed the Asian rights to the drug in July 2011 for $25 million upfront and $69 million in potential milestones plus double-digit royalties on sales and 25% global development expense reimbursement. Bayer has already paid Trius an additional $7 million in milestones since the initial $25 million upfront last summer.

…Quick Financial Snap-Shot…

We forecast that Trius exited 2011 with roughly $60 million in cash and investments, enough to fund operations through the current phase 3 program. We note the company received a $5 million milestone payment from Bayer in January 2012 for completion of the -112 study. For 2012, we expect Trius will actively seek a European partner for tedizolid. We think this could bring in similar, if not more, cash to the deal done with Bayer in July 2011 for the Asian rights.

Conclusion

In January 2011 we initiated coverage of Trius Inc. with an Outperform rating. We are confident in the outcome of the company’s ongoing phase 3 program testing tedizolid vs. Pfizer’s Zyvox (linezolid) for the treatment of acute bacterial skin and skin structure infections (ABSSSI). The first trial, Study-112, offered positive top-line data in December 2011. This trial was run under a U.S. FDA special protocol assessment (SPA). The second trial, Study-113, also under a U.S. FDA SPA, continues on plan, with data expected early 2013. Management is seeking a third SPA for a lung study in 2012. A study in bacteremia could begin in 2013. All-in-all we are very confident in the development program for tedizolid. We believe it represents one of the lowest risk phase 3 assets in biotech.

We see meaningful market share gains for tedizolid over the three market leading products, Zyvox, Cubicin, and Tygacil. The current market cap of only ~$160 million undervalues the story in our view. We think the stock is worth $10 per share based on discounted cash flow (DCF) analysis. Our U.S. peak sales forecast is $350 million. Our global peak sales forecast is $750 million.

Egg On My Face With Trius Call

By Jason Napodano, CFA

Well I've got a little egg on my face this morning. Three days after I published a blog calling the SVP sell-off in shares of Trius (TSRX / $5.45/share) a "Buying Opportunity", management issued 8.6M shares at $5.25/share in a public offering. Including potential over-allotment of 1.29M, and we could be looking at nearly 10M shares coming to the market by the end of the month. That's 25% dilution for existing shareholders.

I question the timing of the deal. If the SVP sell-off was truly a "non-fundamental" decision, then management should have waited for the stock to recover. The trend was back up since I published the article. The stock was $5.80/share yesterday. I think it would have been above $6 next week. Plus, as noted in my blog published on January 23rd, management just received $5M from Bayer on January 23rd. Including over-allotment, that $55M in new cash in January 2012. I now forecast they will exit the Q1-2012 with $108M in cash.

Whatever the reason, now Trius is sitting on a boat-load of cash. Management will say that this puts them in a stronger negotiating position in seeking a European partner for tedizolid. That's what all management's say. I've been doing this for nearly 15 years. It tells me an EU deal is not likely anytime soon.

...Cash Rich...

Phase 3 #2 is ongoing - that's the IV-to-oral step down trial. Phase 3 #3, a HAP/VAP (lung infection) study, is planned for later in 2012. Management is in talks with the FDA on the SPA for the trial. Management wants phase 3 #4 to be a bacteremia (systemic infection) study. However, plans were to do this trial in 2013. Perhaps with $108 million in the bank, management is considering pushing forward with both these in 2012.


We note that management has been doing some initial market research on tedizolid. Obvious strengths include the shorter course of therapy, the lack of myelosuppression, the easier dosing, and the better tolerability. Acknowledged disadvantages upon launch include less familiarity and a single indication. That single indication being, skin infection (ABSSSI). The figure below is from management's investor presentation.
By raising cash today, management may be looking to wipe-out the disadvantages. A product with four successfully completed phase 3 trials will certainly gain physician attention. Familiarity grows even through conducting the clinical trials. Positive data creates marketing advantages. And if the data is included in the NDA filing, and approved by the FDA, then management may be in position to launch tedizolid with three indications at launch - skin, lung, and bacteremia.

Maybe I'm over-analyzing? Maybe I'm too optimistic? I'm just trying to come up with a logical reason as to why a company already with an Asian parter in Bayer paying 25% of the global development costs and $60M in the bank felt it necessary to raise $50M at depressed prices.

...Catalyst Poor...

As much as we like the Trius story, we acknowledge the stock is lacking catalysts. We're not expecting the phase 3 data from the IV-to-oral step down trial until early 2013. The SVP exit and the massive dilutive offering today is surely to irk current holders. Plus, with Citigroup, Piper Jaffray, Canaccord, and Ladenburg shopping around another 10M shares this week, who's left to buy next week?

Trius stock is looking like dead-money for a while. That's frustrating considering I told people to buy it early in the week. If you're a trader, momentum-player, or catalyst-player, you might find better opportunities elsewhere. Come back to Trius this Fall. If you're a Buy-and-Hold investor, you're fine. Long-term, I still like the story. I see $10 as fair-value based on my DCF model. I'll just have to sit tight until I can be right.

pour l'instant, le calme
plat...

Why Trius Therapeutics Is A Gem In The Innovative Antibiotics Market

April 13, 2012


Trius Therapeutics (TSRX) is a biopharmaceutical company that develops and commercializes innovative antibiotics for life-threatening infections. The company announced positive top-line results from their first phase three clinical trial for tedizolid phosphate (TR-701), an IV- and orally-administered, second generation oxazolidinone, for the treatment of serious gram-positive bacterial infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA). The company is located in San Diego, CA, and run by Jeffrey Stein, Ph.D., President and Chief Executive Officer.

Trius' product offerings are significant because they are well-developed, in a proven market that was already pioneered by big pharmaceutical firms. In addition, competition is actually decreasing due to big pharma's lack of investment and development in this space.

The problem to solve

The company's products address the increasing problem of bacterial resistance to currently marketed drugs. As a result, serious and life threatening infections are in some instances more difficult to treat, and in other instances, impossible. Death by MRSA infection in hospitals, exceeds 19,000 deaths a year. That exceeds the number of deaths due to HIV. So because of declining investment in antibiotic solutions by big pharma, (leading to a leaner pipeline), and the upward trend of bacterial resistance, there is a need for novel therapeutics to treat multi-drug resistant bacterial infections.

Enter Trius' (TR-701,) now in phase three clinical development, and partly addressing the pipeline issue for MRSA indications. The company is expected to complete enrollment of the second phase three trial at the end of 2012.

Revenue base

Not common in many biotech companies is actual revenue. Trius has $60 million in revenues, which are government contract revenues, and which fully front three pre-clinical programs through phase one clinical development. It's developing an (Investigational New Drug) engine of sorts, that is going to be putting drugs into a clinical development pipeline. The most advanced of these is their Gyrase-B program, which is expected to enter the clinic in the first quarter of 2013. That project is funded through a $28 million five-year contract from (the National Institute of Allergy and Infectious Diseases), through Phase I clinical development. The federal government's (Biomedical Advanced Research and Development Authority, is also interested in funding it through phase three.

Gyrase is a broad spectrum drug. According to the company's CEO Jeffrey Stein "it has the potential to be the first truly novel class of broad spectrum antibiotic to enter the clinic in the last 50 years. Its potential value could eclipse the value of the company's late stage product, Tedizolid. This information has not been so visible to investors, but investors should get excited about it."

A significant partner

On the collaboration front, Bayer Pharma (BAYZF.PK) is making $69 million of milestone-based payments to Trius for development of Tedizolid - $25 million of it upfront, half of which will be pre-commercial. Bayer, which will market the drug in Asian territories, is paying 100 percent of their development costs in their territory and 25 percent of development costs in higher value territory, all a pretty solid testimonial to the commercial potential of Tedizolid. If things proceed on schedule, $30-35 million of that will be paid before 2015. The agreement with Bayer does not cover the U.S., Canada, or the European Union, and the company expects to develop similar type agreements for those markets.

Investment Value

This creates the position where investors are paying for the late stage products appropriately, but the company is able to build the full research, clinical, regulatory, commercial capabilities that could then be applied to the earlier stage product once it enters the clinic. This represents an opportunity to enhance investor value, somewhat like a free call option for investors, as they're not paying for it but they will get the end value for it. Essentially, the early stage pre-clinical Phase I and II are funded for Trius.

According to public financial statements referencing the end of Q4 2011, the company reported approximately $59 million in cash on hand, not including the $50 million they netted from a January 2012 public offering. According to company officials, the company is capitalized through NDA filing, which they expect will take place in third quarter of next year.

With relatively low risk from a clinical, regulatory, and financial perspective, a current low cost to enter as an investment ($5.12 per share) and a steady stream of catalyst from news and clinical trials for the next few years to benefit its stock, Trius' value is apparent.

Trius is currently trading at $5.12 per share with a 52wk Range of 4.71 - 9.00, and a Market Cap of $197.82 Million.

Disclosure: I have no positions in any stocks mentioned, and no plans to initiate any positions within the next 72
hours.

Tri us Therapeutics: The Calm Before The Storm

March 21, 2012


Biotech investing is often an exercise in "hurry up and wait". Once clinical trials are underway, there's not much for investors to do but wait and hope for positive news like partnerships, setbacks at competitors, or new additions to the pipeline. There's a risk that shares of Trius Therapeutics (TSRX) will go to sleep ahead of pivotal data in early 2013, but biotech investors may want to take a serious look at this under-owned name.

A New Antibiotic For A Market That Needs One

Despite the much-publicized rise of methicillin-resistant staphylococcus aureus (MRSA) and its growing threat to public health, antibiotic development is not a major priority for most large drug companies and biotechs. Some of this is due to difficulty (drugs that are very good at killing bacteria are often quite dangerous for the human taking them), but even more may be due to limited revenue prospects - the entire branded antibiotic market in the U.S. is smaller than the market for many individual cancer drugs.

This creates a real opportunity for Trius's lead compound tedizolid. Tedizolid is a 2nd-generation oxadolidinone that Trius is developing as an IV or oral antibiotic for gram-positive bacteria and conditions like acute bacterial skin and skin structure infections (ABSSSI), pneumonia, and bacteremia.

At this point, tedizolid is in a second pivotal Phase III study, with results due in early 2013. Based on the positive results of the first pivotal study, the odds look good for this drug and Trius could be in position to receive FDA approval as early as 2014. While Trius formed a partnership with Bayer (BAYRY.PK) to market the drug in emerging markets, Trius has held on the marketing rights in the U.S. and Europe and seems to be planning on launching the drug itself in the U.S.

The Benefits And Opportunity

Trius is not positioning tedizolid as a more efficacious antibiotic, but rather a safer and more convenient drug that offers no compromise in efficacy. In the first pivotal study, tedizolid showed fewer serious adverse events than Pfizer's (PFE) market-leading Zyvox (24% vs. 31%), substantially lower GI side-effects (16% v. 25%) and lower platelet suppression (9% vs. 15%).

Tedizolid was administered as a once-a-day pill for six days, whereas Zyvox was administered twice a day for 10 days. The measurements of efficacy for the two drugs were virtually indistinguishable.

The company's current pivotal study (#113) is a little different. It's designed as an IV-to-oral step-down study with a slightly different set of endpoints. Under an SPA with the FDA, Trius will be excluding early clinical failures and pain measurements, but the basic aims of the study are the same as in #112. While the #112 results were solid, investors should realize that no trial is risk-free - there is a chance that the FDA could look at reduction in lesion size vs. stoppage of lesion spread, for instance. That said, the efficacy results seen thus far would suggest that the drug should be approvable if the data from this second study is consistent with the first.

If and when approved, I believe that tedizolid will earn a spot as a drug-of-choice in many hospital settings. Doctors will continue to use vancomycin and Zyvox (particularly after it goes off-patent), but the safety and treatment time advantages of tedizolid should earn it significant usage - time is money in hospital stays and tedizolid holds the real prospect of shaving multiple days off of hospital stays. What's more, with its availability as a pill, tedizolid has definite usage advantages over Cubist's (CBST) Cubicin (which is only available intravenously).

I believe that tedizolid could reap $500 million in sales by 2019, with definite potential upside from broader usage in MRSA settings. The company is also looking to put tedizolid into advanced studies in pneumonia and bacteria, and the upside from those indications and broader MRSA usage could double that initial revenue estimate.

Weighing The Risks

Arguably the biggest risks for Trius shareholders right now are that something bizarre and unexpected goes wrong in the 113 study and/or the FDA finds serious nits to pick when the company files its NDA. Beyond that, too, are the normal risks that go with building a salesforce and conducting a product launch - risks that include the likely need for more capital.

Longer term, there are also competitive risks to consider. Despite increasing resistance and potentially serious side-effects, vancomycin still holds about 70% of the antibiotics market. Then there also other drugs on the market like Zyvox and Cubicin that doctors are already familiar with and comfortable using. Tedizolid has real advantages in safety and its administration profile, but these other drugs are not going to vanish.

Despite my initial lead-in about how relatively little antibiotic development there is, there are other companies with experimental antibiotics in trials. Cempra (CEMP) is looking to move Taksta into Phase 3 studies, and Durata and Rib-X also have antibiotics in advanced studies (dalbavancin and delafloxacin, respectively).

Rib-X also boasts Big Pharma support, as it signed an $800 million worldwide licensing deal with Sanofi (SNY) in mid-2011. That said, Rib-X seems to be positioning/preparing delafloxin more as a stronger/better alternative to vancomycin/Zyvox, as opposed to a safer/easier/more convenient antibiotic.

There's certainly room for more than one new antibiotic on the market, but investors should keep these would-be rivals in mind when thinking about the long-term revenue potential for tedizolid.

One final risk worth mentioning with Trius is the virtually non-existent pipeline behind tedizolid. While the company has some sponsored research activities aimed at developing more potential gram-positive and gram-negative antibiotics, the cupboard is currently bare. Antibiotics take less time to advance through trials than many other kinds of drugs, but the inability to find promising follow-on drugs will create some dis-economies of scale if Trius stays independent and builds out a U.S. salesforce.

The Bottom Line

Tedizolid has clean IP, a well-understood mechanism of action, and what looks like a clean efficacy and safety profile. What's more, it raises the very real prospect of an effective alternative for resistant hospital-acquired infections, as well as a means of shortening hospital stays and reducing overall treatment costs.

On the basis of $500 million in potential sales in 2019, a 30% discount rate, and some assumed future dilution, Trius shares could be worth nearly $12 today. This analysis assumes a future revenue multiple of 7x, which is arguably aggressive. The good news is that even using the much lower multiple of rival Cubist (3.6x) results in a target fair value north of $6 - certainly not so exciting, but still supportive of the idea that Trius is undervalued.

With the results seen to date in tedizolid, the need for new, better antibiotics, and the potential for a significant licensing agreement for European rights, Trius shares seem worthy of serious due diligence from biotech investors.

Disclosure: I have no positions in any stocks mentioned, and no plans to initiate any positions within the next 72 hours.

Piper Jaffray Sees Increased Chance of Trius (TSRX) Partnering in Europe Following Tedizolid Data

The analyst suggested recent data on tedizolid could strengthen Trius' chances of partnering with a European company. The analyst maintains an Overweight rating and a $13 price target on shares of Trius.

comment va ? t'as plus de biotechs en ptf ?

Ca m'arrangerait bien qu'elle décolle car j'en ai un paquet ;-)

oui, j'ai pris du recul avec la bourse, j'y reviendrai quand je pourrai vraiment me le permettre...

si j'avais pu, j'aurais mis aussi un beau paquet sur TSRX, c'est sans doute la seule qui m'attire actuellement, j'espère que tu te les feras en or avec elle ;-)

Salut,

J'avais également repéré TRIUS car en matière de nouveaux antibiotiques, c'est zéro.
Mais je crains , si admis par la FDA, qu'il ne soit réservé qu'à des cas bien précis, comme les entérocoques résistants à la vancomycine et le staphylo doré résistant à la meticiline, afin qu'il ne devienne lui-même très vite résistant si galvaudé.

Il existe déjà une oxazolidinone sur le marché, le linézolide de Pfizer (ZYVOCID(R)) qui déjà n'est déjà administré que dans ces deux cas précis et pas plus de 4 semaines, vu les effets secondaires importants.

à priori le seul catalyseur à court terme serait l'annonce d'un partenariat pour la diffusion de Tedizolid en Europe. Un autre partenariat est envisageable pour les USA, mais quand ? ...

mais il faut bien avoir conscience que Tedizolid appartient aussi à Donga Pharmaceutical ! et que Trius doit verser des paiements d'étapes à cette boite coréenne.

ça calme ... quel intérêt alors de se placer sur Trius ?
si c'est pour faire de la pv à CT, il y a sans doute mieux ailleurs, par contre sur le LT Trius semble offrir certaines garanties
elle me fait un peu penser à AIS ...( je n'ai jamais pu faire une grosse pv sur elle car trop impatient , alors que si j'avais su la garder , elle me l'aurait bien rendu...)

quelles sont ces garanties ? c'est sans doute subjectif , mais le partenariat avec Bayer où la présence de Wellington qui détient plus de 16% des titres peuvent inspirer confiance.

----------------------------------------------------

mais c'est surtout le management qui peut inspirer confiance, en particulier la présence du Dr Philippe G. Prokocimer comme chef médical

le marché des antibios est à renouveler, l'équipe de Trius l'a bien compris, seulement huit nouveaux antibiotiques ont été approuvés depuis 2003 alors que les bactéries deviennent de plus en plus résistantes

ce qui pourrait être intéressant c'est ce qu'ils font en amont, au stade pré-clinique

"Trius Therapeutics initiated IND-enabling studies in December 2011 for a Gyrase-B development candidate with potent activity against Gram-negative bacterial pathogens including multi-drug resistant strains of E. coli, Klebsiella, Acinetobacter and
Pseudomonas."

si du jour au lendemain ils nous annoncent la découverte d'un nouvel agent antibio très prometteur suite à des essais sur des animaux, ça peut très bien booster le cours de l'action

"Antibiotics are also attractive because, unlike in other therapeutic areas, the results of preclinical efficacy and safety studies are highly predictive of clinical success. In other words, if an antibiotic effectively kills bacteria and is determined to be safe in animal models, it has a high likelihood of performing similarly in humans in clinical
trials."

en extrapolant un peu, leurs potentielles découvertes pourraient susciter la convoitise d'autres biopharmas telles que Cubist Pharmaceuticals ou même de plus gros groupes...


mais bon, c'est vraiment subjectif...
je me souviens avoir eu un bon à priori sur CYCC, alors que par la suite j'ai pu me rendre compte qu'elle avait tout d'une "zombie biotech" comme dirait Sacha ...
ou même Adeona ( qui a encore changé de nom ;-))) pour devenir Synthetic Biologics , tout un progamme...) que j'ai toujours considéré comme une coquille vide, ce qui ne l'a pas empêché de monter ces derniers temps de 0.50 à plus de 2.50$...


donc tout est relatif ...

je perçois Trius comme un gage de sécurité pour un investissement LT mais il se pourrait bien que ce soit qu'une boite d'opportunistes qui profitent d'être sur le marché pour s'en mettre plein les poches...

Tackling Drug-Resistant Bacterial Infections

Carol Potera

Trius Therapeutics’ Second-Generation Oxazolidinone Targeted at MRSA


New antibiotics are desperately needed to treat serious drug-resistant gram-positive bacterial infections, such as methicillin-resistant Staphylococcus aureus (MRSA), which place an increasing burden on healthcare resources. To address this need, Trius Therapeutics is testing a second-generation oxazolidinone antibiotic, called tedizolid phosphate, in Phase III clinical trials. Pfizer’s Zyvox® (linezolid) is a first-generation oxazolidinone approved to treat MRSA, and it is the only marketed oxazolidinone.

Previous clinical and nonclinical testing showed that tedizolid has better potency and safety profiles than Zyvox, according to Trius. In fact, the firm claims that tedizolid is four to eight times more potent than Zyvox against both MRSA and vancomycin-resistant enterococci. Other advantages Trius notes for tedizolid include highly efficient oral absorption, rapid in vivo bactericidal activity, and once-daily oral or intravenous (IV) administration. Hospitalized patients treated with the IV drug can be transitioned to the oral form when they are discharged from the hospital.

“It’s unusual in the antibacterial marketplace to have only one member of a drug class,” says Jeffrey Stein, Ph.D., president and CEO. Starting in 2005, Dr. Stein searched worldwide for 18 months to find antibacterial compounds with compelling preclinical efficacy and safety data. He discovered tedizolid at Dong-A Pharmaceutical in South Korea and licensed the compound in 2007.

A Phase I trial in 2008 conducted by Trius compared tedizolid to Zyvox and the results confirmed the potential of Trius’ new drug, Dr. Stein reports. “We were prepared to terminate the development of tedizolid if it did not demonstrate a potential safety advantage over Zyvox in this 21-day study,” he says.
Selective Modifications

Oxazolidinones are small molecule drugs that bind to 23S ribosomal RNA in a specific location and inhibit protein translation. Unlike Zyvox, tedizolid lacks an acetamide group, long assumed to be essential for oxazolidinones to bind to their targets. Strains of MRSA become resistant to oxazolidinones due to mutations at the acetamide site.

“Eliminating the acetamide group minimizes the ability of pathogens to evolve resistance mutations,” says Dr. Stein. Pathogens become resistant to tedizolid 10 times more slowly than to Zyvox, he remarks.

Scientists at Dong-A made tedizolid even better by replacing the acetamide group with a smaller hydroxy methyl group and then adding a phosphate. This makes tedizolid a highly soluble, yet inactive prodrug. The body’s natural serum phosphatases cleave the phosphate ester bond, releasing a highly soluble and active molecule. The highly soluble phosphate group also allows for IV formulation and improves oral bioavailability.

In general, when oxazolidinones are modified to improve potency, they become less soluble and more difficult to formulate as IV drugs. The Korean scientists found “a very clever solution to a problem facing those trying to develop second-generation oxazolidinones,” says Dr. Stein.

Trius Therapeutics announced results of its Phase II trial in June 2009. Patients with complicated skin infections were treated orally with tedizolid for five to seven days. The overall cure rate was 98% for the 200 milligram dose, and patients with MRSA skin infections had a 100% cure rate.

Trius is running two Phase III trials. Top-line data from the first Phase III trial was released in December 2011. The primary endpoint of efficacy noninferiority to Zyvox was met, and noninferiority for safety was also demonstrated, Dr. Stein reports. The second trial is an IV-to-oral transition study, which is still ongoing.
Marine Microbes Next

The preclinical program at Trius focuses on GyrB and ParE, both targets of gram-negative bacteria. GyrB and ParE are needed for DNA replication. They are part of macromolecular complexes that are targeted by the well-known quinolone class of antibiotics. “Our GyrB compounds are hitting the same macromolecular targets as quinolones, but at different binding sites. This makes our lead compounds active against quinolone-resistant pathogens,” says Dr. Stein.

Trius researchers engineered compounds with broad-spectrum activity against gram-negative pathogens like Pseudomonas and Klebsiella as well as gram-positive pathogens like MRSA. A lead series of compounds show good potency in animal efficacy studies, Dr. Stein reports. “This could be the first truly novel class of broad-spectrum antibiotics that are active against all known resistant strains,” he says.

A second preclinical program focuses on a collection of molecules being developed at the Scripps Institute of Oceanography. The antimicrobial agents are derived from marine strains of Streptomyces, a common soil microbe and previously a rich source of antibiotics. However, “Streptomyces in soil has been tapped out with respect to chemical diversity,” says Dr. Stein. The Scripps scientists discovered marine strains with complex metabolic processes and novel chemical diversity. They are screening libraries to identify candidates with potent antimicrobial activity.

Trius Therapeutics benefits from a two-tiered funding structure. The development of tedizolid is backed by private and public investors, whereas federal grants support investigations of the early-stage broad-spectrum antibiotics and marine microorganisms.

The National Institute of Allergy and Infectious Diseases has awarded Trius $27.7 million, and the Defense Threat Reduction Agency has given $29.5 million to identify and develop novel antibiotics or countermeasures for biodefense threats.

“With this structure, our investors’ dollars are focused on our late-stage programs. Yet they can benefit from the potential upside of our early-stage programs if any of them progress into the clinic,” says Dr. Stein.

moi je fais gaffe avec les analystes. ça vient appuyer mon sentiment. mais j'ai un manque de confiance marqué envers eux

en effet, impressionnant leurs objectifs sur ZLCS

ce qui soulève une autre question: quels critères utilisez-vous pour vous placer sur une biotech ?

certains utiliseront l'analyse technique, d'autres tenteront de se placer avant une décision FDA ou l'annonce de résultats

en ce qui me concerne, j'essaie de soupeser tout ce que je peux trouver sur la boite mais c'est clair que ce qu'il en résulte n'est qu'une question de feeling

pas facile d'investir sur une biotech, la part d'incertitude et de risque y est énorme, mais le gain peut être bien supérieur à ceux des autres secteurs, c'est sans doute pour ça que nous sommes là...
