COVID-19: Petrovax launched an international clinical trial of Polyoxidonium for novel coronavirus infection

The Ministry of Health of the Russian Federation has approved a Phase III international, multicenter, placebo-controlled clinical trial of the Russian branded medicine Polyoxidonium (azoximer bromide) to treat COVID-191.

On the back of the global COVID-19 pandemic, Petrovax is implementing a large-scale study program on Polyoxidonium to treat this condition. The company has launched an international, multicenter, adaptive, randomized, double-blind, placebo-controlled, comparator clinical study of efficacy and safety of Polyoxidonium® 6 mg, powder for solution for injection, for the treatment of hospitalized COVID-19 patients in Russia.

Concurrently, a clinical trial application for Polyoxidonium in COVID-19 patients is being reviewed by the French Ministry of Health. The filing in Slovakia is under preparation. Petrovax is also negotiating with regulators potential studies in other countries.

The multicenter Polyoxidonium study is conducted in accordance with the WHO Protocol2. In Russia, the study will embrace clinical sites in Moscow, Nizhny Novgorod, Orenburg, and Yaroslavl. It will assess the medicinal product’s efficacy and safety in adult COVID-19 patients (males and females) 18-85 years of age. At Stage 1 of the study, 100 patients will be enrolled. A total of 454 patients is expected to be included in Stages 1 and 2 of the study. Preliminary clinical results are expected in June.


— An international clinical trial of Polyoxidonium for COVID-19 that we are launching both in Russia and abroad is an ambitious large-scale project for a Russian branded medicinal product. We plan to study its efficacy for COVID-19 in line with top evidence-based medicine standards. Petrovax is striving to contribute to the fight against coronavirus pandemic guided by the best clinical practices and highest ethical principles.
Petrovax President Mikhail Tsyferov noted

The results from Polyoxidonium use studies in patients with infectious diseases suggest that the product may potentially be efficacious for the treatment of SARS-CoV-2-infected patients. There is the first successful experience of Polyoxidonium administration in COVID-19 patients in Slovakia. Based on that experience, the product has been entered into the national clinical guidelines for the treatment of COVID-19 patients3. We are proud that our study is the first and so far the only international, double-blind, placebo-controlled, clinical trial of a Russian branded medicinal product to treat the novel coronavirus infection.”

Apart from the international, multicenter clinical trial, Polyoxidonium is currently being used in routine clinical practice in COVID-19 patients in Russia, the CIS, and Slovakia, including within the framework of an observational study.

— We are fast to learn from this experimental experience, and we use these experimental data in our work
said Mikhail Tsyferov

The company has also been donating Polyoxidonium as a preventive agent for the staff of some clinical sites.

— On behalf of all Petrovax staff members, I would like to give credit to and thank all doctors and other healthcare professionals who safeguard human lives and health in the hard times
stressed Petrovax President
