Biotech portfolio updates – Esperion, Trevena, Exelixis and ArQule

Esperion – Positive read-through from Repatha

Shares of Esperion (ESPR) doubled within two weeks after Amgen (AMGN) announced positive CVOT (cardiovascular outcomes trial) outcome for Repatha, Amgen’s PCSK9 antibody. Although this news will make the lipid-lowering field more competitive for Esperion, it also validates the LDL hypothesis and removes some regulatory risk around Esperion’s LDL-lowering pill, bempedoic acid (ETC-1002).

Until now, investors assumed Esperion will need to have CVOT data in order to file for approval but now the likelihood of FDA approval based on positive LDL readout in 2019 is much higher. Beyond regulatory uncertainties, investors’ primary concern revolves around whether an oral drug with a 25% LDL reduction has room in a market dominated by generic oral drugs (statins, Zetia) on the one hand, and branded highly effective (50%-60% LDL reduction) PCSK9 antibodies on the other.

Biotech selloff leaves Wall Street disillusioned

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.

Biotech portfolio updates – Thoughts on ongoing correction and upcoming catalysts

The biotech sector is having a brutal summer, with major indices (IBB, FBT, XBI) down 15-20% from their July highs. Even after this decline, valuations for most biotech stocks are still rich and need to come down by an additional ~25% in order to become reasonably priced. As my working hypothesis includes a correction (with significant fluctuations) going into 2016, I still plan to have a significant cash position and complement it with leveraged short bio ETFs.

Trevena – Late stage innovation flying under the radar

Post-surgical pain is not the first indication people think about in the context of innovative drugs. From an investor standpoint, pain in the acute care setting is perceived as a temporary, symptomatic hospital-related issue with a poor value proposition. Some may even claim the unmet need is limited given available treatments (especially opioids). This is demonstrated by Trevena’s (TRVN) modest market cap ($264M) despite a positive clinical signal, an ongoing phase 2b and a potential FDA approval within three years. 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
