Prestige Biopharma Limited has submitted a request to the U.S. Food and Drug Administration (FDA) for a pre-submission meeting to discuss the company's planned Biologics License Application (BLA) for its Herceptin Biosimilar, HD201(Tuznue®). The Biosimilar Biological Product Development (BPD) Type 4 Meeting is to discuss the format and content of a BLA in advance of the final submission. The company will discuss the overall development program of HD201 with the FDA to identify potential filing and review issues.

The meeting is expected to take place around November, and the BLA submission by the end of the year. The company's HD201 is a proposed biosimilar to Roche's Herceptin® (trastuzumab) to be prescribed for the treatment of human epidermal growth factor 2 (HER2) positive breast and metastatic gastric cancer. Trastuzumab targets HER2, which is overexpressed in some types of cancer cells and stimulates the growth of the cancer cells.

Trastuzumab works by selectively binding to HER2, thereby stopping the growth of these cancer cells. Currently, a New Drug Submission (NDS) for HD201 is under review by Health Canada and a Marketing Authorisation Application (MAA) by the Korea Ministry of Food and Drug Safety. In addition to filing a new MAA to the European Medicines Agency (EMA), the company also plans to apply for authorisation in other advanced biosimilars markets such as UK, Australia, and Singapore.
