Esperion – Seeing the glass half full

Esperion (ESPR) has been the target of a lot of criticism lately, demonstrated by the collapse from $115 to $24 in just 5 months. Investors became skeptical about Esperion’s ability to get FDA approval without cardiovascular outcomes data, which may push approval by 2-3 years and decrease probability of success. Even if the drug obtains FDA approval, many are worried about a narrow label that will limit initial commercial opportunity. Continue reading

ASCO 2015 preview

As in previous years, the upcoming ASCO meeting will be dominated by immuno-oncology with a particular focus on PD-1 antibodies. The market’s primary focus is expected to be on non-small cell lung cancer (NSCLC) with data from three large randomized trials from BMS (BMY) and Roche. Beyond lung cancer, investors will look for additional indications where PD-1 agents may have clinical utility as monotherapy or in combination with other agents.

Overall, PD-1 programs continue to generate positive data across many indications but to date clinical experience has been sobering. PD-1 antibodies may lead to durable responses in some cases but the vast majority of patients derive limited benefit or don’t respond at all. This is true in most indications with the exception of melanoma where PD-1 antibodies have a dramatic impact and combination with Yervoy appears to lead to further improvement. Below is a recap of some of the data which will be presented over the weekend. Abstract numbers and links are also provided. Continue reading

Biotech portfolio update – 2014 summary and 2015 preview

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.

Biotech portfolio update – Three readouts and an acquisition

There was a lot of activity in my coverage universe in the last two weeks, including positive data readouts for three companies and an acquisition announcement. However, of the four cases, only two resulted in share appreciation.

Ambit – To keep or not to keep (the CVR)

Two weeks ago, Ambit (AMBI) agreed to be acquired by Daiichi Sankyo in a deal that included a $15 upfront payment and $4.5 in Contingent Value Right (CVR) per share. The CVR represents a milestone-like mechanism in which Ambit’s shareholders may eventually get additional payments equal to 30% of the initial purchase price. Continue reading

Drugs to watch at ASCO 2014

Below is my ASCO 2014 preview (better late than never…). I tried to make this recap as comprehensive as possible but it is practically impossible to cover all the interesting stuff (let me know if I missed anything dramatic). Unlike last year, I decided to group interesting abstracts based on mechanism of action rather than companies in order to provide a more holistic perspective. On top of attending the conference itself, I will try to attend as many analyst events as possible (this year I have Clovis, Roche, BMS and Incyte on my list) and include them in my post-ASCO write-up. Continue reading

Top picks for ASH 2013

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.).

Below are my top picks.   Continue reading

Biotech portfolio update – Array, Morphosys, Onyx and Synta

Array Biopharma – Following Puma’s footsteps

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

Threshold Scores Big With Pancreatic Cancer Data

Last month, Threshold Pharmaceuticals (THLD) surprised the market with positive data for its lead program (TH-302) in pancreatic cancer. Although actual results were not published and despite several issues with the trial design, TH-302 generated what is possibly the best pancreatic cancer data set in over a decade. Continue reading

Drugs to Watch at ASCO 2011

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. Continue reading

Exelixis- Going Where No Drug Has Gone Before

Last week, Exelixis (EXEL) presented updated results for its lead agent cabozantinib (also known as XL184 or “cabo”). Cabo had become a closely watched agent last year after demonstrating unique and unprecedented activity in prostate cancer patients, leading to either partial or complete resolution of bone scans in 19 out of 20 patients. This effect had never been seen with any of the approved or investigational agents for prostate cancer, leading to widespread enthusiasm but also some skepticism.

Following last week’s data, it is now safe to say cabo has a real effect on bone metastases. The data set included 100 response evaluable patients, 62 of whom were evaluable for bone response. 85% of these patients experienced partial or complete resolution of their bone scans (the bone mets shrank or disappeared), 13% had stabilization and 2% (1 patient) had progression. Cabo had a profound effect on bone pain as well as markers for bone metabolism, implying the drug also has potential utility for treating bone related complications.
