A new Cuban vaccine against chronic hepatitis B, created by the Genetic Engineering and Biotechnology Center, or CIGB, is currently undergoing clinical trials in eight countries, organized with the collaboration of the French company Abivax, official media reported Tuesday.
Named HeberNasvac, this new product is injected via nasal passages or subcutaneously, and has proved to be "safer and more effective" than all other existing medications available for this virus, the official daily Granma said on its front page.
Clinical trials of HeberNasvac are being made with a sample of 230 patients in 50 clinics in Australia, New Zealand, Singapore, South Korea, Taiwan, Hong Kong, the Philippines and Thailand.
The protocol for the medical evaluation was designed by leading experts contracted by Abivax along with Cuban scientists, according to officials at the CIGB, who confirmed the satisfactory progress of the trials in Asia, one of the regions most affected by the virus.
According to figures of the World Health Organization, or WHO, close to 1 million deaths occur every year related to the hepatitis B virus, one of the chief causes of cancer of the liver, cirrhosis of the liver and other complications like ascites, varicose veins of the esophagus and splenomegaly.
A second clinical study of the new vaccine, still in the phase of recruiting the sample of patients, will take place at 13 medical centers in Cuba and will benefit 160 patients on the island, the official news agency Prensa Latina said.
In Cuba, where projects related to creating new medications have several times won the National Prize of the Academy of Sciences, use of the vaccine is expected to begin in 2016, after being approved for inclusion in the medical register by the Cuban Center for State Control of Medications, Equipment and Medical Devices.
In November 2014, Cuba announced that preventive vaccines against cholera, pneumococcus and hepatitis B were being prepared for registration and application this year. All were described as highly innovative, safe and effective products by medical authorities on the island. EFE
