Stage one of Biotron's Hepatitis C drug trial completed
Biotron Limited has completed stage one of a human trial of its lead hepatitis C drug candidate, BIT225. Twelve patients have been dosed in the first half of the trial being undertaken by ACLIRES, an international contract research organisation (CRO) that specialises in running antiviral drug clinical trials. All are infected with the most common strain of the Hepatitis C virus, genotype 1.
The second half of the trial - which also involves 12 patients - is now underway and expected to be completed in May, with results anticipated to be analysed and released in June. The trial is blinded, so no results are available until samples are analysed at the conclusion of the trial and the data is unblinded.
Biotron CEO, Dr Michelle Miller, said the trial was proceeding as expected and the results would be "of international interest".
She said BIT225 was a first-in-class drug candidate which specifically targeted the p7 protein, a viral protein essential to virus production and replication.
"We are happy with how the trial is progressing. We achieved the necessary ethics and drug import approvals to move to the second stage of the trial, which is now underway."
Twelve further patients are now being recruited and dosed over four weeks with BIT225.
As in stage one of the study, one-third of patients are being given a placebo, one-third a dose of 400mg BIT225 and another one -third are being dosed at 200mg BIT225.
This Phase II trial is examining how BIT225 works in combination with current approved treatments for HCV, Interferon and Ribavarin.
Existing drugs have limited effectiveness and can be toxic. Doctors say fifty per cent of sufferers do not respond to current therapies, signalling a need for new treatments that directly target and halt replication and reproduction of the virus.
