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 →
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 →
ArQule (ARQL) has doubled in less than two months, following two years of weakness. While tivantinib’s phase III liver cancer is the company’s most visible asset, investors are starting to notice ArQule’s early stage pipeline and its potential to generate meaningful data in the coming year. Both ARQ 092 (Akt inhibitor) and ARQ 087 (FGFR inhibitor) are being tested in biomarker-enriched trials with the potential to have clear efficacy signals during 2015. Continue reading →
Last night, Roche and Foundation Medicine (FMI) announced a strategic collaboration under which Roche will become the majority owner in Foundation Medicine. Roche will become Foundation’s marketing partner and intends to use the company’s tests for its drug development projects.
Roche is paying $1.03B for 56.3% of the company, representing a price per share of $50 (109% premium over Friday’s close). For investors, the deal validates the bull thesis for Foundation (which I discussed here) as the undisputed leader of NGS-based tumor profiling. Turns out that being first matters also in the diagnostics business! Continue reading →
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.
Earlier this week at the EORTC meeting, Clovis provided an update on rociletinib (CO-1686) and rucaparib. Not only do the data prove that both drugs are highly efficacious in the relevant patient populations, they also provide key distinguishing factors (safety profile and patient selection) relatively to competing programs. The negative market reaction exemplifies the discrepancy between the progress Clovis is making and its stock behavior. Continue reading →
Clovis (CLVS) was one of ASCO’s clear losers following safety issues for its lead program, CO-1686. Despite demonstrating robust efficacy in T790M+ lung cancer, hyperglycemia associated with the drug raised concerns about its ultimate market positioning vs. its close competitor, AstraZeneca’s (AZN) AZD9291. Continue reading →
As expected, the major theme this year was (again) Immuno-oncology with a focus on PD-1 antibodies. Another theme that is gaining momentum is segmentation of tumor types to small niches based on high resolution genomic profiling. This approach can be used to identify a drug’s target population already in phase I, as exemplified by multiple presentations I will discuss below. In most cases, these drugs are ineffective in the general population but highly effective in rare subsets of cancer patients. Continue reading →
