For the three months ended March 31, 2018, Mateon reported a net loss of $0.8 million, a decrease of $3.2 million from the net loss of $4.0 million reported for the three months ended March 31, 2017.

“During the first quarter of 2018 our efforts were focused on obtaining capital so that we could advance our product candidates,” said William D. Schwieterman, M.D., Chief Executive Officer of Mateon Therapeutics. “After receiving the initial funds from our April financing transaction, we authorized our clinical investigators to resume screening new patients into our clinical study of OXi4503 in relapsed/refractory acute myeloid leukemia and myelodysplastic syndromes. Based on our encouraging preclinical data, we are also planning for a new clinical study of CA4P as an immuno-oncology agent in combination with Opdivo® – initially evaluating the combination in advanced melanoma patients who have not responded to currently approved treatments.”
