Mateon terminates ovarian cancer study, restructures


Mateon Therapeutics (OTCQX:MATN) terminated its Phase 2/3 FOCUS after a third scheduled interim analysis of CA4P in combination with bevacizumab (Avastin) and physician’s choice chemotherapy in patients with platinum-resistant ovarian cancer because of a clear efficacy signal.

Due to the lack of a meaningful improvement in PFS, combined with the unfavorable partial response data, the company does not believe that continuation of the study is appropriate. Therefore, Mateon is immediately terminating the FOCUS study and further development of CA4P.

“We are clearly disappointed that CA4P did not show a clinically meaningful benefit when it was added to the current standard of care in platinum-resistant ovarian cancer,” Dr. William Schwieterman, president and CEO, said in a statement.

Given the company’s limited financial resources, Mateon is implementing various near-term cost reduction measures, which include a significant reduction in personnel, representing a decrease in the company’s workforce of approximately 60% since the beginning of the year. The remaining members of the senior management team will take 50% salary reductions, effective immediately.

“Going forward, our immediate focus is to obtain value from our OXi4503 program in AML, which, within the last two months, has shown clear positive clinical outcomes in relapsed/refractory patients,” Dr. Schwieterman said.

As always, we are exploring all options for additional fundraising and adding value for our stockholders, which includes continuing to look for buyers for any or all of our assets,” he added.
