Could gene therapy become biotech’s growth driver in 2017?

Despite bouncing off a 2-year low, biotech is still an unpopular sector and investors are rightfully concerned about its near-term prospects. Recent drug failures, growing pricing pressure and the potential impact of biosimilars all contribute to the negative sentiment, but the main problem is the lack of growth drivers for the remainder of 2016 (and potentially 2017).

Notes from ASCO 2016

Although this year’s ASCO contained a limited amount of groundbreaking data, it provided some interesting take-aways and signaled important trends in oncology drug development.  Below is my take on a quiet but important meeting.

Immuno-oncology – PD-1 combinations at their infancy

As in previous years, the meeting was dominated by PD-1/PD-L1 antibodies. Now that PD-1 blockers have been tested on every tumor known to mankind (see below a great figure from Merck), focus is shifting to combination regimens with PD-1 as a backbone. Combination partners range from other immune checkpoints to chemotherapy, targeted therapy and radiation. Continue reading

Biotech portfolio update – Clovis, Array, ImmunoGen

Clovis Oncology

Clovis (CLVS) lost 75% of its market cap last week after disclosing a disappointingly low response rate for rociletinib in T790M+ NSCLC patients. Updated response rates were 28%-34%, dramatically lower than the 54-60% response rate reported at ASCO 2015. According to the company, the dramatic difference stems from analyzing the same data set based on more stringent criteria (confirmed response rate). Continue reading

Biotech portfolio update – Sage, Marinus and Immunogen

A new lucrative indication for Sage (and potentially Marinus)

Last week, Sage (SAGE) surprised the market by announcing preliminary but impressive results for SAGE-547 in patients with postpartum depression (PPD, also known as postnatal depression). Four patients with severe PPD experienced a dramatic improvement in their depression score from an average of 26.5 to 1.8. In other words, these patients entered the study with a severe debilitating depression and became symptom-free within 2-3 days. Despite the preliminary nature of the results, they generated a clear efficacy signal that merits evaluating SAGE-547 in a randomized trial, to be started later this year. 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

Will 2015 mark the turnaround for antibody-drug conjugates?

Back in 2010, ADCs were the hottest theme in oncology with the potential to revolutionize cancer treatment. The excitement was based on promising results for Adcetris (Seattle Genetics [SGEN]) and Kadcyla (Immunogen [IMGN]), both of which utilized new and improved ADC technologies. Adcteris and Kadcyla were perceived as the ultimate cancer drugs: They had strong single agent activity and provided meaningful benefit to patients with limited toxicity. All that was left to do was replicating their success with additional antibodies to cover every tumor type. 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.

The AML pipeline – New approaches starting to bear fruit

AML (Acute myeloid leukemia) remains one of the few blood cancers in which no progress has been made for decades. This is in contrast to other blood cancers where novel treatments have turned fatal conditions into chronic diseases with long term remissions. Prominent examples are CML, which today has a low mortality rate and multiple myeloma where median survival is approaching 8 years and counting. The recent launch of Imbruvica and Gazyva followed by the anticipated approval of ABT-199 is expected to have a similar impact on CLL as well as on certain subtypes of B cell lymphoma. 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.

6 stocks on my watch list

The recent pullback in the biotech sector hit the vast majority of small/mid cap biotechs. As a group, it is hard to argue biotech stocks are cheap right now but some stocks are becoming attractive after losing 30-50% in several months.  Below are 6 companies that are approaching or already are at attractive valuations.  A key theme for all 6 is that they have been sold off alongside the general market rather than for fundamental reasons. Market fluctuations in 2014 may present investors with attractive entry points.  Continue reading
