Committee for Medicinal Products for Human Use

Committee for Medicinal Products for Human Use (CHMP)The Committee for Medicinal Products for Human Use (CHMP) is the committee within the European Medicines Agency (EMA) responsible for human medicines. The CHMP replaced the former Committee for Proprietary Medicinal Products (CPMP) in May 2004.The CHMP plays a vital role in the authorization of medicines in the European Union (EU). In the centralized procedure, the CHMP is responsible for: 1) conducting initial assessments of marketing authorization applications across the EU; assessing modifications or extensions to existing marketing authorizations (“variations”); considering recommendations from the Agency’s Pharmacovigilance Risk Assessment Committee regarding the safety of medicines on the market, and, where necessary, advising the European Commission to amend the marketing authorization of a medicinal product, or to suspend or withdraw it from the market.The CHMP also evaluates medicines authorized at the national level that are referred to the EMA, with the aim of maintaining a harmonized position throughout the EU.Furthermore, the CHMP and its working groups promote the development of medicines and pharmaceutical regulation by: providing scientific advice to companies researching and developing new medicines; developing scientific and regulatory guidelines to assist pharmaceutical companies in preparing marketing authorization applications for human medicines; and collaborating with international partners to harmonize regulatory requirements.


March 05, 2021 /Bio ValleyBIOON/ --GlaxoSmithKline(GSK) recently announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion, recommending approval of the anti-PD-1 therapy dostarlimab (formerly TSR-042) as a monotherapy for the treatment of patients with mismatch repair-deficient (dMMR)/microsatellite instability-high (MSI-H) recurrent or advanced endometrial cancer who have experienced disease progression during or after platinum-based chemotherapy.

The CHMP’s opinion will now be submitted to the European Commission (EC) for review, which typically issues its final decision within two months. If approved,Dostarlimab will become the first anti-PD-1 therapy approved in Europe for endometrial cancer.

GSK Senior Vice President andTumorDr. Axel Hoos, Head of R&D, stated, “Treatment options for women with recurrent or advanced endometrial cancer are limited, and the prognosis is generally poor. The CHMP’s positive opinion brings us closer to providing dostarlimab as a new treatment option for patients with endometrial cancer in Europe, with the aim of improving outcomes.”

Endometrial cancer (EC) is a major type of uterine cancer that originates in the endometrium. EC can be classified as mismatch repair-deficient/microsatellite instability-high (dMMR/MSI-H) or mismatch repair-proficient/microsatellite stable (MSS). Treatment options are limited for patients with EC who experience disease progression during or after first-line therapy. EC is the sixth most common cancer among women worldwide.

Regulatory Application for Dostarlimab in the Treatment of Endometrial Cancer, Based on Data from the GARNET Study. These data represent the largest dataset for anti-PD-1 monotherapy in the treatment of endometrial cancer. The results showed that dostarlimab provided clinically meaningful outcomes in patients with recurrent or advanced MMR/MSI-H endometrial cancer who experienced disease progression during or after platinum-based chemotherapy: an overall response rate (ORR) of 42% (95% CI: 31–55) and a disease control rate (DCR) of 58% (95% CI: 45–69).

Endometrial cancer is the sixth most common cancer among women worldwide. Although endometrial cancer in its early stagesDiagnosiscan be successfully treated, but for women with recurrent or advanced endometrial cancer whose disease progresses during or after first-line treatment, there remains a significant unmet medical need in terms of treatment options.

Dostarlimab is an investigational humanized anti-PD-1 monoclonal antibody that binds to the PD-1 receptor and blocks its interaction with the ligands PD-L1 and PD-L2. Currently, dostarlimab is under review by the U.S. FDA and the European EMA for the treatment of female patients with recurrent or advanced dMMR/MSI-H endometrial cancer who have experienced disease progression during or after platinum-based chemotherapy. Additionally, dostarlimab is also under review in the United StatesFDAreview for the treatment of adult patients with dMMR recurrent or advanced solid tumors. (Bioon.com)
