Last week’s approval of Alnylam’s (ALNY) Onpattro, the first FDA-approved siRNA drug, serves as a reminder for the bumpy road new technologies go through on their way to the market. From an investor perspective, siRNA has gone in and out of fashion over the years with dramatic shifts in market sentiment. It started with unrealistically high expectations, deteriorated to deep pessimism due to clinical setbacks, followed by gradual sentiment improvement in recent years (with some hiccups along the way).

To me, the main challenge in today’s biotech market is finding good quality assets with attractive valuations. There are definitely a lot of promising programs out there but valuations are often hard to justify as they reflect limited development risk and unrealistic commercial potential. From a risk/reward standpoint, it is hard to get excited about valuations of >$0.5B for companies before clinical proof of concept and $2-5B for clinically validated programs.
From that perspective, Xenon (XENE) is a market anomaly, with two promising clinical stage programs, a robust discovery platform and a market cap of just under $100M. Its two epilepsy programs, XEN1101 (Kv7 opener) and XEN901 (Nav1.6 inhibitor), are still in P1 but at the current levels the upside potential is too significant to ignore. Continue reading
It is hard to overestimate the impact of the Novartis (NVS) /Avexis (AVXS) deal. So far, big biopharmas have had limited exposure to gene therapy and those that did get into the field focused on early-stage collaborations: Pfizer/Bamboo, Biogen/AGTC, Roche/ 4DMT, Abbvie/Voyager etc. This is understandable given the unique product profile gene therapies represent: One time irreversible treatment, lack of long term follow up and creative reimbursement models.
The $8.7B acquisition of Avexis, just three months after the deal with Spark (ONCE), makes Novartis the first pharma to embrace gene therapy as a commercial opportunity. The deals also make Novartis the undisputed gene therapy leader with (hopefully) two products on the market next year. Continue reading
After being the industry’s graveyard for over 20 years, there is finally room for optimism in CNS (central nervous system) disorders. The void created in the field is now being filled by small companies which are using novel therapeutic (gene therapy, antisense, antibodies) and development (genetic validation in humans, biomarkers for patient selection) approaches. While clinical results are early and sparse they may represent the beginning of a new innovation cycle in CNS. Continue reading
After a two-month break here is a recap of key highlights from the September/October time frame. On the menu today: PD-1 controversies at ESMO 2016, Exelixis’ (EXEL) launch in renal cancer, gene therapy data from Abeona (ABEO), long awaited update from Esperion (ESPR) and a positive surprise from Seattle Genetics (SGEN).
ESMO 2016 – Merck wins by a landslide (for now…)
While ESMO is typically secondary in importance to ASCO, this year’s meeting overshadowed its US counterpart (which was relatively quiet to begin with…), generating big headlines in the PD-1 arena. Continue reading
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
As if sentiment around Smid-cap biotechs wasn’t bad enough, Q1 provided a painful reminder of the high failure rate in biotech. The slew of disappointing results at ASH in December 2015 (which I discussed here) was followed by numerous clinical failures and regulatory setbacks. Most notable blowups came from Celldex (CLDX), Incyte (INCY), Alkermes (ALKS), Oncomed (OMED), Chimerix (CMRX), Atara (ATRA), PTC (PTCT) and Portola (PTLA). Continue reading
The past six months have been quite frustrating for Exelixis (EXEL) investors (myself included). The company had a string of positive announcements for cabozantinib (cabo) and Roche-partnered cobimetinib (Cotellic) including positive overall survival readouts for both drugs. Since the July announcement on the METEOR study in renal cancer, the stock is up only 16% despite having a wholly owned drug with a blockbuster potential, imminent approval and significant label expansion potential. Continue reading
After 5 years of a raging bull market, more than 140 IPOs and tens of billions in proceeds, there is a debate on whether the violent selloff in biotech stocks is a hiccup or the beginning of a real correction. I have no idea where the sector is heading in the coming weeks but it seems like the overall sobering experience coupled with this month’s selloff changed Wall Street’s perception around biotech. Investors are finally realizing drug development is fraught with uncertainty and that biotech is an attractive but not infallible segment, which is why I expect the correction to continue in 2016.

Although hematology represents a small portion of human diseases, its weight in the biotech equity markets is disproportionally high. Bluebird (BLUE), Agios (AGIO), Juno (JUNO), Kite (KITE), Cellectis (CLLS), Pharmacyclics (PCYC), Incyte (INCY), Genmab (GEN.CO), Seattle Genetics (SGEN) and Acceleron (XLRN) all derive the majority of their valuations from hematology drugs. This is also the case for larger companies such as Amgen (AMGN), Celgene (CELG) and Alexion (ALXN). Continue reading
