Company working to open a multi-site Phase II clinical trial to assess efficacy

HOUSTON--()--Bio-Path Holdings, Inc., (NASDAQ:BPTH) (“Bio-Path”), a biotechnology company leveraging its proprietary DNAbilize™ liposomal delivery and antisense technology to develop a portfolio of targeted nucleic acid cancer drugs, today announced positive results from the eighth and final cohort of the safety segment of Bio-Path’s Phase II trial assessing the toxicity of the Company’s lead product candidate, BP1001 (Liposomal Grb2 antisense), in combination with low-dose cytarabine (LDAC) chemotherapy in patients with advanced acute myeloid leukemia (AML).

Patients in Cohort 8 were treated with 90 mg/m2 of BP1001 twice a week over a four-week period, in combination with a standard regimen of frontline LDAC. Results were consistent with those seen in previous cohorts, demonstrating BP1001 to be safe and well tolerated, with signs of anti-leukemia activity. The Company saw no adverse events attributable to BP1001 treatment. In Cohort 8, two AML patients achieved partial remission. One patient continues to receive additional treatments.

“The encouraging results from the eighth and final cohort of the safety portion of this trial are exciting not just for Bio-Path, but also for patients suffering from blood cancers like AML,” said Peter Nielsen, President and Chief Executive Officer of Bio-Path. “These results reinforce our confidence in BP1001 as a safe and effective treatment for AML in combination with frontline chemotherapy. We look forward to assessing the efficacy of BP1001 in the Phase II clinical trial.”

With the closing of Cohort 8, the Phase II safety assessment of BP1001 in combination with low-dose cytarabine is complete. The safety assessment included two cohorts, which assessed six patients evaluated with 60 mg/m2 and 90 mg/m2 of BP1001 in combination with low-dose cytarabine. No toxic side effects attributable to BP1001 treatment were observed at either dose. Of the six evaluable patients included in both cohorts of the safety segment, two achieved complete remission, while two others achieved partial remission. Of the patients responding, their blood properties show improvement, suggesting BP1001’s potential efficacy as a combination therapy.

The Company is in the process of submitting these results to the U.S. Food and Drug Administration and is planning to open the efficacy portion of the Phase II trial of BP1001 in the second quarter of 2016.
