OncoGenex Regains Rights to Custirsen from Teva
BOTHELL, Wash. and VANCOUVER, British Columbia, April 27, 2015 /PRNewswire/ -- OncoGenex Pharmaceuticals, Inc. (NASDAQ: OGXI) today announced that its wholly owned subsidiary, OncoGenex Technologies Inc., executed a termination agreement with Teva Pharmaceuticals Ltd. (NYSE: TEVA) under which OncoGenex will regain rights to custirsen, an investigational compound currently in Phase 3 clinical development as a treatment for prostate and lung cancers. This transfer of rights occurs in connection with the termination of the 2009 collaboration agreement between OncoGenex and Teva.
"OncoGenex is excited to move forward with the clinical investigation of custirsen in patients with advanced cancers who desperately need new treatment options," said Scott Cormack, President and CEO of OncoGenex. "The finalization of this agreement gives OncoGenex control of custirsen's development, including the ability to move forward with plans to modify the ENSPIRIT trial design and statistical analysis plan to enable the trial to continue with fewer patients, increased confidence in success and shorter time to regulatory submission."
The agreement between the two parties to terminate the collaboration includes a $23.2 million payment from Teva.
This payment reflects a $27 million advance reimbursement amount less $0.8 million for expenses incurred by Teva in 2015 prior to the termination date as well as a $3 million holdback amount that may be used to settle additional expenses incurred by Teva related to the continued development of custirsen as well as certain indemnity claims. One half of the then remaining balance of the holdback amount will be released to OncoGenex in October 2015 with a further half of the then remaining amount paid in January 2016. Any final remaining amount will be released in April 2016.
In addition, OncoGenex will take over responsibility for all custirsen expenses, including those related to the ENSPIRIT trial, as well as manufacturing and regulatory activities for custirsen programs that were previously managed by Teva.
The company recently reported that as of December 31, 2014, it had $47.1 million in cash, cash equivalents and short-term investments, excluding the advance reimbursement payment from Teva. OncoGenex expects that the $23.2 million payment from Teva and the Company's current resources should enable the completion of the AFFINITY trial through data readout in late 2015 or early 2016, allow for the continuation of the ENSPIRIT trial through the second interim futility analysis expected in mid-2015, and facilitate the achievement of key apatorsen clinical milestones, such as the completion of patient enrollment in the Borealis-2™ trial and final data from the Spruce™ and Rainier™ clinical trials.
Additional terms of the agreement with Teva can be found in the Company's Current Report on Form 8-K filed today and available at http://ir.oncogenex.com.
About Custirsen
Custirsen is an experimental drug that is designed to block the production of the protein clusterin, which may play a fundamental role in cancer cell survival and treatment resistance. Clusterin is upregulated in tumor cells in response to treatment interventions such as chemotherapy, hormone ablation and radiation therapy and has been found to be overexpressed in a number of cancers, including prostate, lung, breast and bladder. Increased clusterin production has been linked to faster rates of cancer progression, treatment resistance and shorter survival duration. By inhibiting clusterin, custirsen is designed to alter tumor dynamics, slowing tumor growth and resistance to partner treatments, so that the benefits of therapy, including survival, may be extended.
