Ebola, Marburg Virus Treatments Safe in Phase 1 Studies

In continuation of my update on antisense drugs and RNAi

AVI BioPharma Inc. announced positive safety results from the first five cohorts of Phase 1 single ascending dose trials of AVI-6002 and AVI-6003, AVI's lead drug candidates being evaluated for the treatment of the Ebola virus and Marburg virus.

Data were evaluated by an independent Data and Safety Monitoring Board (DSMB), which issued recommendations for both studies to progress as planned to the next highest dosing level after no safety concerns were identified. The Phase 1 single ascending dose trials are designed to characterize the safety, tolerability, and pharmacokinetics of each therapeutic candidate in healthy adult volunteers.

"We are very encouraged that these two drugs, which use our advanced PMOplus chemistry, have demonstrated a favorable safety profile through five cohorts in our dose-escalation studies,”says Chris Garabedian, president and chief executive officer of AVI BioPharma...

To date, 25 healthy human subjects (five per group) have been enrolled into five sequential dose groups in each of the two studies. Within each group, four subjects received the indicated dose of the therapeutic and one subject received placebo. For each group, safety, clinical laboratory and renal biomarker results through five days after treatment were reviewed by a DSMB. Subjects enrolled in the sixth group for the drug studies will receive 9.0 mg/kg of the therapeutic or placebo. Final, un-blinded safety and pharmacokinetic results for all subjects will be available upon completion of the trial.

Both candidates employ AVI's patented PMOplus technology that selectively introduces positive charges to its phosphorodiamidate morpholino oligomer (PMO) backbone to improve interaction between the drug and its target.
