REHOVOT, Israel, Sept. 08, 2020 (GLOBE NEWSWIRE) -- Kamada Ltd. (NASDAQ & TASE: KMDA), a plasma-derived biopharmaceutical company, today announced the completion of enrollment and initial interim results from its ongoing Phase 1/2 open-label, single-arm, multi-center clinical trial in Israel of the Company’s anti-SARS-CoV-2 plasma-derived hyperimmune immunoglobulin (IgG) product as a potential treatment for coronavirus disease (COVID-19).

The trial is designed to assess the safety, pharmacokinetics, and pharmacodynamics of Kamada’s plasma-derived IgG product in hospitalized, non-ventilated COVID-19 patients with pneumonia. A total of 12 eligible patients (age 34-69) were enrolled in the trial and received the Company’s product at a single dose of 4 grams IgG within five to 10 days of initial symptoms. Patient follow-up will occur for 84 days.

To date, five of the 12 patients have completed 21-day post-treatment follow-up, two patients have completed 14-day post-treatment follow-up and the additional five patients have completed 7-day post-treatment follow-up. Symptoms improvement was observed in 11 of the 12 patients within 24 to 48 hours from treatment. All 11 patients were subsequently discharged from the hospital within a median hospital stay of 4.5 days from treatment.

The medical condition of one patient, who completed the 14-day post-treatment follow-up, deteriorated and this individual is currently on mechanical ventilation. One patient had a serious adverse event four days after treatment, which was categorized by the investigator as unrelated to the Company’s IgG product, that the patient received in the trial.

“The safety profile of our IgG product and symptoms improvement preliminarily demonstrated by these results are favorable and we plan to continue characterizing the virus neutralization activity of the product in order to calibrate the treatment dose,” said Dr. Naveh Tov, Kamada’s VP Clinical Development and Medical Director.
