It’s been a long road, but Astrazeneca plc’s anti-CTLA4 antibody, tremelimumab, finally earned its first U.S. FDA nod, cleared for use in combination with anti-PD-L1 drug Imfinzi (durvalumab) to treat patients with unresectable hepatocellular carcinoma (HCC). The commercial impact of the dual checkpoint therapy, however, remains to be seen, as it goes up against Roche Holding AG’s combination of Avastin (bevacizumab) and Tecentriq (atezolizumab), which gained standard-of-care status in first-line HCC in 2021.

Expanding its mandate to accelerate access to essential medicines to people in low- and middle-income countries, the Medicines Patent Pool signed its first voluntary licensing agreement for a cancer treatment, Novartis AG’s Tasigna (nilotinib). A twice-daily oral drug, Tasigna is a tyrosine kinase inhibitor included on the World Health Organization’s Model List of Essential Medicines as a second-line treatment for adult and pediatric chronic myeloid leukemia.

The U.S. FDA wants more data on PTC-518 before PTC Therapeutics Inc.'s phase II study of Huntington’s disease can continue enrollment. While stopped in the U.S., the study of the oral, small-molecule splicing modifier still is enrolling participants at sites in several European countries and in Australia.

In a bit of déjà vu, the U.S. FDA’s Obstetrics, Reproductive and Urologic Drugs Advisory Committee once again voted that Makena (hydroxyprogesterone caproate) should be withdrawn from the U.S. market while a second confirmatory trial is designed and conducted. But this time around, the committee’s 14-1 vote was much more decisive than its 9-7 vote in 2019.
