(Sharecast News) - GSK said its gynaecological cancer drug candidate had revealed positive results from early trials and would swiftly move to late-stage five clinical studies globally in the next few months.

The company on Sunday said Mocertatug Rezetecan, known as Mo-Rez, shrank or eliminated tumours in 62% of patients with ovarian cancer where chemotherapy had failed, and in 67% of those with endometrial cancer.

Hesham Abdullah, GSK's global head of cancer research and development, said: "Treatment of gynaecological cancers remains a major challenge, with a pressing need for new therapies that offer improved response rates. With Mo-Rez we now have compelling evidence of a promising clinical profile."

Endometrial cancer affects 1.6 million women globally, with 417,000 new cases each year. Ovarian cancer affects 843,000 people, with 240,000 new cases annually.
