Vernalis achieves a $3 million milestone payment from Corvus Pharmaceuticals Inc

WINNERSH, UNITED KINGDOM--(Marketwired - Feb 14, 2017) - Vernalis plc (LSE: VER) is pleased to announce the achievement of a clinical milestone from its collaboration with Corvus Pharmaceuticals Inc ("Corvus") triggering a payment of $3 million to Vernalis.

In February 2015, the Company licensed exclusive, worldwide rights to its adenosine receptor antagonist programme, CPI-444, for use in all therapeutic applications to Corvus, a US-based biotechnology company focused on developing novel immuno-oncology therapies.

CPI-444 is a patented small molecule that is now being evaluated in a Phase 1/1b trial in patients with advanced cancers. It is the lead molecule in Corvus' pipeline and is being developed both as a single agent and in combination therapy. The clinical trial utilizes an adaptive design that allows expansion of disease-specific cohorts upon reaching certain pre-defined endpoints.

Corvus announced positive data from its Phase 1/1b study in January 2017, having achieved the clinical study protocol criteria for expansion in the cohort of patients with renal cell carcinoma with single agent CPI-444. This study expansion triggers the first clinical milestone payment of $3 million under the licensing agreement. Corvus has stated that, if early findings are confirmed with longer follow up and a larger set of patients in this expanded study, a registration trial could commence by the end of 2017.

Corvus was launched through a $33.3 million Series A fundraising in 2014 by the founder and former senior management at Pharmacyclics Inc and it raised a further $74.8 million Series B fundraising in 2015 and $70.7 million via a US IPO in March 2016.

The licensing deal has the potential for Vernalis to earn approximately $220 million in milestones from all indications, subject to development, regulatory and sales milestones being achieved. In addition, there are mid-single digit royalties payable if a product reaches the market, with the potential to reach low-double digit royalties in certain circumstances.

Ian Garland, CEO of Vernalis commented "We are delighted with both the speed of progress of CPI-444 and the promising indication of single-agent activity in renal cell carcinoma patients as well other disease cohorts. Corvus has a wealth of clinical and commercial expertise and continues to demonstrate that it is an ideal partner for the program. We will watch progress with a great deal of interest over the remainder of 2017."
