Shanghai – March 5, 2020. - Zhimeng Biopharma, Inc. today announced the initiation of the first-in-human dosing of ZM-H1505R in its Phase I clinical study in the United States. ZM-H1505R is a novel, investigational HBV capsid formation inhibitor that is being developed by Zhimeng Biopharma for the treatment of chronic HBV infection. Primary results showed that the drug is safe and well tolerated in health volunteers tested.


The current PhaseI clinical trial of ZM-H1505R in the United States is a randomized, double-blind, placebo-controlled sequential single and multiple ascending dose (SAD/MAD) study following oral administration in healthy subjects to evaluate the safety, tolerability, and pharmacokinetics of ZM-H1505R. Zhimeng anticipates the full results from this study to be released by the third quarter of this year.  Immediately following this trial, the clinical study of ZM-H1505R in China with HBV-infected patients will be conducted later this year.


Different from the reported Type I and Type II HBV core protein allosteric modulators (CpAMs), ZM-H1505R is a novel pyrazole molecule that has a new binding site in the HBV core protein. It inhibits HBV replication by hindering the packaging of pre-genomic RNA (pgRNA) into the viral capsid and by blocking the formation of HBV covalently closed circular DNA (cccDNA).


"The first-in-human dosing of ZM-H1505R in the United States is a key step forward in our pursuit of a functional cure for chronic HBV infection. It is also an important milestone for Zhimeng, as it marks our transition to a clinical-stage company,” said Huanming Chen, Ph.D., Chief Executive Officer of Zhimeng Biopharma. “Currently there are about 250 million people worldwide chronically infected by HBV and nearly one million people die from HBV-related liver diseases each year. Current treatments rarely cure the HBV infection and the drugs have to be taken for life. It is clear that there is a significantly unmet need for new drugs for HBV infection. We are excited that the ZM-H1505R-101 clinical trial is underway and hopeful that ZM-H1505R has the potential to become a critical component of a curing regimen for chronic HBV infection”.
