Exelixis – What’s Next?

Sunday, July 25th, 2010


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 winner of ASCO 2010 - BMS

Thursday, July 1st, 2010

The hottest theme at this year’s 2010 ASCO (American Society of Clinical Oncology) annual meeting was without a doubt cancer immunotherapy, an old paradigm that deals with redirecting the patient’s immune system against tumors. After decades of failures, this concept is finally proving itself useful. There are basically two approaches:  1) cancer vaccines that aim at eliciting an immune response against specific targets on cancer cells and 2) immunomodulatory drugs that aim at stimulating the immune system in a more general manner (not target specific). The undisputed leader in cancer vaccines is Dendreon (DNDN), which currently has the only FDA approved cancer vaccine. Following ASCO, it looks like the leader in immunomodulation drugs is BMS (BMY).

Immunogen – Another Step towards FDA Approval

Sunday, April 18th, 2010

Earlier this week, Immunogen (IMGN) got closer than ever to having a commercial product in the market. During its quarterly call, Roche removed the regulatory overhang on T-DM1’s near term fate after it disclosed plans to file for T-DM1’s approval already this year. The submission will be based on results from a recently announced phase II trial where T-DM1 demonstrated overwhelming activity in late stage breast cancer patients. Until now, it was unclear whether the FDA would be willing to consider approval based on a single arm phase II trial. Roche’s decision implies the FDA gave its unofficial and non-binding blessing for the accelerated approval.

Arqule Joins The Phase III Club

Sunday, April 11th, 2010

No matter how diversified or well managed a biotech company is, eventually there is no escape from binary events. These events usually come in the form of data readout from clinical trials that can make or break the stock. Two weeks ago, Arqule (ARQL) announced topline results from a much anticipated   phase II trial of its lead agent, ARQ 197, in lung cancer. The trial is evaluating ARQ 197 in combination with the approved drug, Tarceva, in patients with non-small cell lung cancer (NSCLC) who have been previously treated with chemotherapy. Although the data set is not a clear slam dunk, it generated an impressive efficacy signal that warrants advancing ARQ 197 into phase III. This, coupled with the progress the company has made on other fronts in the past year makes Arqule one of most attractive biotech stocks in the market.

A Busy Month for Immunogen (Part I)

Monday, November 30th, 2009


 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.

Incyte – Life After Debt (Part II)

Sunday, October 18th, 2009

For part I click here

 

On top its JAK programs, Incyte has been developing two additional programs it intends to out-license. The first program is INCB13739 for diabetes, which already reached clinical proof of concept and could be licensed imminently. The second program, INCB7839 for breast cancer, is less advanced but could become very interesting later this year depending on data from an ongoing trial.

Curagen – Positive Results at ASCO 2009

Sunday, July 5th, 2009


Last month at the ASCO meeting, Curagen (CRGN) presented results for its lead drug, CR-011, in breast cancer and melanoma patients. CR011 had activity in both indications, however, most of the drug’s value should be ascribed to the breast cancer program, which represents a huge commercial opportunity and better chances of approval.

As I previously wrote, the significance of the breast cancer trial is not only in the clinical activity of CR-011, but more importantly, the ability to identify patients who are likely to respond to the drug. By defining the right target population, Curagen could substantially improve chances of approval, shorten development time and enjoy high market acceptance. (more…)

The Winner of ASCO 2009

Sunday, June 14th, 2009


This year’s ASCO was packed with promising early stage trials, but very few positive late stage trials with an impact on medical practice. The two most important practice changing trials were phase III studies for Eli Lilly’s (LLY) Alimta and Roche’s (RHHBY.PK) Herceptin. These drugs are likely to enjoy a boost in revenues starting from next year, as both demonstrated impressive survival prolongation in lung and gastric cancer patients, respectively. The studies also underscore the paradigm shift in the industry towards personalized medicine, where a drug is given only to patients who have a high likelihood of deriving benefit. This article will focus on Alimta, which was, in my opinion the winner of ASCO 2009. (more…)

Micromet– More Reasons For Optimism

Friday, May 8th, 2009

Two weeks ago, Micromet (MITI) hosted its annual R&D day, where it discussed plans for 2009 and beyond. The meeting provided plenty of information regarding the company’s technology and drug candidates, but more importantly, it served as an appetizer for next month’s EHA meeting. As a reminder, Micromet is expected to present data from 2 trials evaluating its lead agent, blinatumomab (MT103), in two forms of blood cancer: Non-Hodgkin Lymphoma (NHL) and Acute Lymphoblastic Leukemia (ALL).

During the R&D day, the company (intentionally and unintentionally) shared some previously undisclosed results from the trials. The new information, which includes impressive efficacy signals from both studies, further solidifies blinatumomab’s position as one of the most promising investigational agents in oncology. Based on its spectacular performance, blinatumomab has a high chance of getting approved as soon as 2012.

Micromet – The Plot Thickens

Thursday, April 23rd, 2009


The past 12 months have been anything but boring for Micromet’s shareholders (MITI). Last summer, Micromet’s stock climbed to $7 following excellent clinical data (discussed here) and a landmark publication in Science Magazine (discussed here), but since then the company has lost half of its value. Volatile trading is quite standard for small, cash burning biotechnology companies, however, Micromet’s case was particularly frustrating.

 

Micromet invented a new class of antibodies it calls BiTE (Bispecific T-Cell Engager) antibodies. Unlike conventional antibodies, BiTE antibodies bind two targets, the first target is presented on a cancer cell and the second is presented on an immune cell. The simultaneous binding of both cells by the BiTE antibody can redirect the immune cell to attack the cancer cell, thus exploiting the body’s natural immune mechanisms to fight cancer. Conceptually, a BiTE antibody is similar to cancer vaccines, which also aim at producing an immune response against tumors. Despite a history of failures in the field of immunostimulating antibodies, it looks like Micromet has found the right formula.
