Bio-Path Holdings Announces Successful Completion of Cohort 7 of Phase Ib Clinical Trial Evaluating Liposomal Grb-2 in Acute Myeloid Leukemia

HOUSTON--()--Bio-Path Holdings, Inc., (NASDAQ:BPTH) ("Bio-Path"), a biotechnology company developing a liposomal delivery technology for nucleic acid cancer drugs, today announced the successful completion of Cohort 7 of its Phase Ib clinical trial evaluating the toxicity of its lead compound, Liposomal Grb-2, combined with low-dose cytarabine (LDAC) chemotherapy in patients with advanced Acute Myeloid Leukemia (AML). Bio-Path has opened enrollment into Cohort 8, which will complete the Company's Phase Ib study of Liposomal Grb-2.

Furthermore, one patient achieved complete remission during treatment. A second patient demonstrated improvement in bone marrow blasts at the end of the first treatment cycle and is continuing Liposomal Grb-2 treatment as part of an additional treatment cycle. The third evaluable patient completed the treatment cycle, but did not show improvement. One patient ended the study early due to disease progression, and therefore was not evaluated in this cohort.Three patients were evaluated in Cohort 7, which was the first cohort of the Company's Phase Ib trial to evaluate the toxicity of Liposomal Grb-2 as a combination therapy. Patients were treated twice a week for four weeks with 60 mg/m2 of Liposomal Grb-2, for a total of eight doses in combination with the standard regimen of LDAC. Results were consistent with previous cohorts, showing Liposomal Grb-2 to be safe and well tolerated.

"I am highly encouraged to see that a patient suffering from advanced AML who was treated with Liposomal Grb-2 has achieved complete remission, and that another patient is continuing to improve," said Peter Nielsen, President and Chief Executive Officer of Bio-Path. "Complete remission in a patient with refractory and treatment-resistant AML is an exciting milestone for Bio-Path and blood cancer patients, suggesting that Liposomal Grb-2 might have the potential to improve survival rates in combination with frontline chemotherapy. We anticipate that these positive results will support rapid enrollment into Cohort 8, and look forward to continuing the development of Liposomal Grb-2."

Bio-Path has opened Cohort 8 for patients to be treated with 90 mg/m2 of Liposomal Grb-2, in combination with frontline LDAC. Upon successfully completing the evaluation of three patients in Cohort 8, the Company will finalize the Phase Ib clinical study.
