Novartis AG is bolstering its radioligand arsenal with the takeout of Mariana Oncology Inc. for $1 billion up front and as much as $750 million in potential milestone payments.

The company’s lead program, MC-339, is a radioligand approach to small-cell lung cancer, due to enter the clinic later this year.

X4 Pharmaceuticals Inc. is raring to go with marketing after the firm scored U.S. FDA approval of Xolremdi (mavorixafor) capsules for patients 12 years and older with warts, hypogammaglobulinemia, infections and myelokathexis, or WHIM syndrome, to increase the number of circulating mature neutrophils and lymphocytes.

Acrivon Therapeutics Inc.’s $130 million financing disclosed April 9 hiked confidence in then-pending data with ACR-368 (prexasertib), the selective small-molecule inhibitor that targets checkpoint kinase 1 (CHK1) and CHK2.

Gilead Sciences Inc. is aiming to capitalize on the early August 2022 buyout of privately held U.K. biotech Mirobio Ltd. with the advancement of PD-1 agonist GS-0151 into phase Ib trials for rheumatoid arthritis, a decision that Leerink analyst David Risinger hailed as positive for others at work with the intriguing mechanism.

Cerevel Therapeutics Inc.’s positive results from the long-shot pivotal phase III Tempo-3 trial with tavapadon – the first D1/D5 receptor partial agonist being studied as a once-daily treatment for Parkinson’s disease – added gravy to the $8.7 billion takeover by Abbvie Inc., disclosed late last year. The buyout’s centerpiece was the late-stage asset emraclidine, a positive allosteric modulator of the muscarinic M4 receptor, touted as a potential best-in-class, next-generation antipsychotic for schizophrenia, which strikes more than 5 million people in the G7 (U.S., France, Germany, Italy, Spain, U.K. and Japan).
