METEOR Data Accepted for Oral Presentation in Presidential Session

Detailed data from METEOR, the phase 3 pivotal trial of cabozantinib in advanced renal cell carcinoma, will be presented at the ECC as a late-breaking abstract in the Presidential Session I on Saturday, September 26, 2015. In July 2015, Exelixis announced that the trial met its primary endpoint, demonstrating a statistically significant increase in progression-free survival for cabozantinib versus an active comparator, everolimus, in a population of patients who experienced disease progression following treatment with a VEGF receptor tyrosine kinase inhibitor.

The details of the presentation are as follows:

Session from 14:30-16:40 CEST (8:30-10:40 a.m. EDT); presentation expected to begin at 16:20 CEST (10:20 a.m. EDT)

Cobimetinib Data Accepted for Proffered Paper and Poster Sessions

Also at the meeting, Exelixis’ collaborator Genentech, a member of the Roche Group, will present data on cobimetinib, an Exelixis-discovered compound, in combination with vemurafenib in previously untreated patients with advanced malignant melanoma harboring the BRAF V600 mutation.

About Cabozantinib

Cabozantinib inhibits the activity of tyrosine kinases including MET, VEGF receptors, AXL, and RET. These receptor tyrosine kinases are involved in both normal cellular function and in pathologic processes such as oncogenesis, metastasis, tumor angiogenesis, and maintenance of the tumor microenvironment.

COMETRIQ (cabozantinib) is currently approved by the U.S. Food and Drug Administration for the treatment of progressive, metastatic medullary thyroid cancer (MTC).

The European Commission granted COMETRIQ conditional approval for the treatment of adult patients with progressive, unresectable locally advanced or metastatic MTC. Similar to another drug approved in this setting, the approved indication states that for patients in whom Rearranged during Transfection (RET) mutation status is not known or is negative, a possible lower benefit should be taken into account before individual treatment decisions.

About the Cobimetinib Development Collaboration

Exelixis discovered cobimetinib internally and advanced the compound to investigational new drug (IND) status. In late 2006, Exelixis entered into a collaboration agreement with Genentech, under which Exelixis received initial upfront and milestone payments in connection with signing the agreement and submitting the IND. Exelixis was responsible for development of cobimetinib through the determination of the maximum tolerated dose in phase 1, at which point Genentech exercised its option to further develop the compound.

In November 2013, Exelixis exercised its option to co-promote cobimetinib, if approved, in the United States. Exelixis is entitled to an initial equal share of U.S. profits and losses, which will decrease as sales increase, and will share in the U.S. marketing and commercialization costs. Exelixis is eligible to receive royalties on any sales of the product outside the United States.
