This is the second part of an article I posted back in April. The final list includes only 9 candidates, as one of the candidates (Seattle Genetics’ SGN-75) was taken off the list after generating fairly disappointing results at ASCO. Enjoy.

Micromet

Micromet (MITI), who is developing antibodies for cancer, definitely has a potential game changer in its hands. The company’s lead agent, blinatumomab (Bmab), belongs to a new class of antibodies called BiTE (Bispecific T cell Engagers). These antibodies can harness the patient’s immune system to attack tumors by redirecting T cells (the most potent immune cells in the body) against cancer cells. BiTE antibodies achieve this by simultaneously binding a cancer cell on one side and an immune cell on the other. This unleashes a potent anti-tumor immune response. (more…)

More melanoma breakthroughs

This year’s meeting will probably be remembered as a historical event with regards to melanoma. Last year, it was a phase III trial for BMS’ (BMY) Yervoy (ipilimumab), which was the first in history to show a survival benefit in advanced melanoma patients (discussed in my ASCO 2010 write up). This trial led to Yervoy’s historical approval 3 months ago.

This year, investigators will present studies evaluating Yervoy as well as Plexxikon/Roche’s vemurafenib in pretreated melanoma patients. Yervoy was evaluated in combination with chemotherapy while vemurafenib was compared with chemotherapy. According to BMS’ and Roche’s press releases, both studies were successful and each drug led to a survival benefit.  The extent of this benefit is still unknown and will be revealed only at the conference.

In its earnings release last week, Seattle Genetics (SGEN) did not surprise anyone with the financial guidance and expected timelines for approval of its lead agent, SGN-35. However, on the business development front, the release did include an intriguing announcement that did not receive the attention it deserved. The company announced that Genentech recently advanced 3 new antibody drug conjugates (ADC) based on Seattle Genetics’ technology to phase I, this is in addition to the CD22 ADC already in clinical testing.

The announcement has several important implications for Seattle Genetics. First, the number of clinical programs in its partnered pipeline instantly jumped 50% from 6 to 9. By definition, this provides Seattle Genetics with more shots on goal and increases chances of substantial milestones and royalties down the road. More importantly, it establishes Seattle Genetics’ technology as Genentech’s preferred ADC platform, an attractive position given Genentech’s dominance in oncology and ADCs in particular. (more…)

Last week, Sanofi-Aventis (SNY) announced disappointing results from a phase III trial evaluating iniparib in breast cancer. The drug failed to improve survival and progression-free survival (PFS) in breast cancer patients and although actual data were not published, approval is unlikely even for a subset of patients. Failed phase III trials are quite common in oncology, a field with one of the highest attrition rates in the pharmaceutical industry. Nevertheless, iniparib’s failure is particularly disturbing, as the phase III was supported by compelling results from a randomized controlled phase II trial as well as strong scientific rationale. Importantly, this trial could have broader implications as it raises questions regarding the role of randomized phase II trials as a go/no go decision point for pivotal trials.

As expected, earlier this month at the annual American Society of Hematology (ASH) meeting, Seattle Genetics (SGEN) reported positive results that will likely lead to the company’s first ever regulatory approval for Brentuximab vedotin (SGN-35). The data will transform Seattle Genetics into a commercial stage company, with an initial market opportunity of ~$250M in the US alone. In addition, the results further validate the company’s ADC (antibody drug conjugate) technology, which has broad utility and huge commercial potential. In particular, Seattle Genetics could become a market leader in hematology by next year’s meeting, with results for two additional ADCs.

Array’s (ARRY) shares keep on fluctuating in the $2.5-$3.5 range, relatively unchanged from the beginning of 2010. It seems that the market is having trouble assessing the real value of the company and its pipeline, which includes 13 (!) drugs in clinical trials. With a market cap of ~$170M, the market puts an average price tag of $13M per asset, a ridiculously low valuation (assuming no value is assigned to the company’s discovery platform). The company’s long term debt (due in 2014) could be partially blamed for this anomaly, but the problem seems to be more related to the company’s business model. The good news is that during the next year the company is looking at multiple events that might change the way Wall Street views Array. (more…)

Exelixis (EXEL) came under a lot of pressure recently and the stock is now trading near its 52 week low following two unrelated events that took place last month. In late June, the company announced the resignation of its CEO, George Scangos, who was appointed as Biogen Idec’s (BIIB) CEO. Earlier that month, the company announced BMS (BMY) decided to give back rights for Exelixis’ flagship product, XL184. Adding to the pressure are interesting but not stellar clinical results for some of the company’s compounds at ASCO and potentially an additional partnership termination. (more…)

 The month of December has always been a busy period for biotech investors, due to two important events:  The annual meeting of American Society of Hematology (ASH) and the San Antonio Breast Cancer Symposium (SABCS). Every year, these events produce clinical data that can sharply move biotech stocks in both directions. This year, Immunogen (IMGN) is about to get center stage attention at both events.

At ASH, the company and its partners will present phase I data for three different agents powered by Immunogen’s antibody-drug conjugate (ADC) technology.  The most important of which is Sanofi-Aventis’ (SNY) SAR3419 in Non-Hodgkin lymphoma, a common form of blood cancer. Later that month at SABCS, Roche/Genentech is expected to present results for T-DM1, a high profile ADC for the treatment of breast cancer.

Only two and a half weeks have passed since the launch of the model portfolio, so it is still too early to assess its performance, nevertheless, even after a sharp decline in two stocks, the portfolio seems more robust than the general market. Since inception, the biotech portfolio, co-managed by Ran Nussbaum and myself is down “only” 3.6%, compared to the Nasdaq and S&P which are down 8.5% and 6.7%, respectively for the same period.    

Based on recent market action and the unprecedented level of anxiety, it seems that the bottom is getting closer and hopefully, the markets will stabilize towards the end of 2008. Therefore, the coming weeks may be a good opportunity for increasing exposure to the stock market, which is why we intend to end 2008 with 90-95% of the portfolio in stocks.

The past year certainly was not an easy one for Arqule’s (ARQL) investors who saw their shares plummet more than 50%. Perhaps this kind of decline does not look too big of a deal for a small biotech company when compared with “solid” investments such as AIG (AIG) or Citi (C), but the current price level is certainly not what the institutionals who bought $55 million worth of stock for 7.75$ a share last year envisioned. The good news is that now, with a new management team and an imminent partnership deal for Arqule’s lead compound, ARQ-197, the stock represents an opportunity for an aggressive upward move in 2009.

The company has been talking about licensing ARQ-197 for some time now, but based on remarks made by its new CEO, there are active discussions with potential partners that could mature into a deal in the near future. Last month, the Oppenheimer & Co healthcare team issued an insightful report titled “Collaborations as Catalysts” which mentioned ARQ-197 as a potential licensing candidate. According to Oppenheimer, although such a licensing deal could happen already this year, it is more likely to happen next year following the release of clinical data from ongoing clinical trials.
