FOCUS for platinum-resistant ovarian cancer
FOCUS is a phase 2/3 study in patients with platinum-resistant ovarian cancer, evaluating whether the addition of CA4P to the current standard-of-care (bevacizumab plus chemotherapy) improves progression-free survival. As of
OX1222 for acute myeloid leukemia
OX1222 is a dose-ascending phase 1b/2 clinical trial evaluating OXi4503 in combination with cytarabine in patients with recurrent/relapsed acute myeloid leukemia (AML). Mateon recently completed enrollment and treatment for the fourth cohort of 7.81 mg/m2 of OXi4503, and no dose limiting toxicities or significant safety issues were identified among the three patients. One patient treated in the fourth cohort experienced a significant AML blast reduction, with blast counts going from 89% upon enrollment to 7% following the first cycle of treatment. However, the patient subsequently experienced an unrelated adverse event and withdrew from the study approximately two weeks after the last dose of OXi4503 in the second cycle of treatment, prior to an additional blast measurement and accordingly did not meet the criteria for a complete remission. Three complete remissions were observed in the first three cohorts (19% overall in the clinical trial to date), each of which occurred after two cycles of treatment, and two complete remissions remain on-going at 12+ and 3+ months. Enrollment is on-going in the fifth cohort of 9.76 mg/m2 of OXi4503.

Following review of the data available for the patients in PAZOFOS, the company does not believe any changes or adjustments to Mateon's FOCUS study are warranted. FOCUS has restrictive enrollment criteria for patients with pre-existing cardiovascular risk factors and specific algorithms for treatment of patients that experience blood pressure increases.
"We are pleased that studies in both our core programs, the FOCUS study of CA4P for platinum-resistant ovarian cancer and Study OX1222 of OXi4503 for AML, are enrolling well and showing a good safety profile, as well as initial indications of efficacy," stated
"The investigator-sponsored PAZOFOS study, which uses CA4P with a different combination of drugs for recurrent
ovarian cancer, also holds significant potential for patients and we're hopeful that enrollment will resume soon,"
At Mateon, we believe that we can significantly improve cancer therapy by employing these two complementary approaches simultaneously. When utilized this way, VDAs obstruct existing blood vessels in the tumor leading to significant central tumor cell death while AAs prevent the formation of new tumor blood vessels.
Mateon is committed to leveraging our intellectual property and the product development expertise of our highly skilled management team to enable VTT to realize its true potential and to bring much-needed new therapies to cancer patients worldwide.
