Below is my traditional end of the year summary and a recap of catalysts for 2015. As always, I did my best to cover the most important events, let me know if I missed anything… I would like to use this opportunity and wish the readers of this blog a happy and prosperous new year.
In 2013, Seattle Genetics’ (SGEN) Adcetris reached market saturation in its approved labeling (relapsed/refractory HL), shifting market attention to label expansion. These include DLBCL, where Adcetris showed impressive efficacy in highly refractory patients (42% response rate, PFS of 5 months) and CTCL (73% response rate). Adcetris is in phase III for earlier stages of HL as well as CTCL, which are viewed as the next opportunity to grow sales. The company will outline its registration strategy for DLBCL in early 2014.

The annual ASH (American society of hematology) meeting will take place next month in New Orleans. Based on the abstracts that were released 2 weeks ago, it seems that after 2 phenomenal years of introducing novel mechanisms, this year’s meeting is going to be more on the evolving landscape in each segment (Btk/PI3K inhibitors, antibody drug conjugates, myelofibrosis, CD38 antibodies, chimeric antigen receptors etc.).
On a standalone basis, phase I results presented by Epizyme (EPZM) for its lead program, EPZ-5676, were not as negative as market reaction implies. The company was able to dose escalate through several cohorts without serious side effects, demonstrate target modulation in humans and show mild signs of efficacy. For a typical biotech company, that would be considered a reasonable phase I data package, given the possibility to explore higher potentially more efficacious doses. Unfortunately, an early stage biotech company with a market cap of ~$1B based purely on preclinical results and hype is anything but typical. Continue reading →
Earlier this week, Genmab (GEN.CO) announced the first J&J (JNJ) – initiated study for daratumumab, an anti-CD38 antibody that already demonstrated phenomenal clinical activity in multiple myeloma. The announcement comes after a drought of more than a year without any new clinical trials or meaningful clinical data. From this point onwards, investors should expect J&J to accelerate daratumumab’s development with a broad and aggressive program, just like it did with ibrutinib. Continue reading →
Last month Array Biopharma (ARRY) announced a licensing deal with Oncothyreon (ONTY) for ARRY-380, a selective HER2 kinase inhibitor for the treatment of HER2+ breast cancer. ARRY-380 is regarded as an insignificant program, evidenced by the modest deal size ($10M upfront) and the lack of market reaction, but this could change once investors make the connection between ARRY-380 and Puma Biotechnology’s (PBYI) neratinib (EGFR/HER2 inhibitor). Although neratinib is more advanced, backed by more clinical data and probably has broader potential, ARRY-380’s selectivity profile could differentiate it in certain clinical settings. As the market is clearly excited with neratinib (Puma has a market cap of ~$1.6B), some of the excitement could eventually be tunneled toward Array as well. Continue reading →
Earlier this month, I attended the TAT (Targeted anticancer therapies) congress in Paris. This conference focuses exclusively on targeted therapies for cancer, one of the most active areas in drug development. As a small conference (~500 participants), it does not generate a lot of high profile clinical data, still, it is a great opportunity to “feel the pulse” of oncology drug development. Speakers include clinical oncologists, basic scientists and industry researchers, which provide a fairly broad spectrum with respect to existing and upcoming trends.
Here, I focus on three major themes from the meeting: PD-1 inhibitors, antibody drug conjugates (ADCs) and cancer metabolism. Continue reading →
Immunogen (IMGN) concluded the week with a market cap of ~$1B, up 200% in less than a year. This valuation is quite unusual for a company that ascribes the vast majority of its value from a 3-5% royalty stake in a single drug – Roche’s T-DM1. T-DM1, which utilizes Immunogen’s antibody-drug conjugate (ADC) technology, comprises of Herceptin conjugated to a drug payload. It is in two phase III trials and multiple phase II studies in breast cancer. If proven effective, many believe T-DM1 will eventually replace Herceptin, at least in certain treatment lines.
Earlier this week, Incyte (INCY) announced positive phase III results for its lead agent, INCB424, in myelofibrosis (MF). Although the full data set was not published, it will almost certainly lead to FDA approval, opening up a $200-$300 market in the US alone. Another similar phase III trial which will be reported in the coming months should support approval in Europe as well.
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.
