A little-known biotech’s high-stakes cancer bet just paid off and its shares doubled

By · Published by Everything Blog

In short

The Danish company's recent clinical momentum was led by petosemtamab, which cut the risk of death by 50% when combined with Merck's Keytruda for head and neck cancer. Genmab also posted positive Phase 3 results in October for Rina-S in ovarian cancer and Epkinly in diffuse large B-cell lymphoma. Historically dependent on royalties from partnered drugs like Darzalex and Kesimpta, the firm now holds full ownership of both petosemtamab and Rina-S following major acquisitions. Currently, the drugmaker is running 15 Phase 3 trials across its lead candidates ahead of its November 5 earnings report.

The announcement marked Genmab's third successful Phase 3 trial in October, following positive results for treatments targeting ovarian cancer and lymphoma.

After nearly three decades spent building Genmab into one of Europe's prominent biotechnology companies, CEO Jan van de Winkel told CNBC on Friday the breakthroughs marked "a completely new era."

Historically, Genmab made money from royalties from drugs it helped develop, including Johnson & Johnson's multiple myeloma treatment Darzalex and Novartis' Kesimpta. Van de Winkel said Johnson & Johnson is expected to generate $16.5 billion to $16.9 billion in Darzalex sales this year, with Genmab receiving royalties of up to 20%.
