BMY opts-in for worldwide rights_to PRTA’s anti-tau compound, PRX005:
https://www.businesswire.com/news/home/20230710599297/en
PRTA reported phase-1 data for PRX005 in Alzheimer’s disease in Jan 2023 (#msg-171085895).
BMY opted in for the US rights to PRX005 in 2021 (#msg-164573926), which resulted in an $80M milestone payment to PRTA. Today’s opt-in for the ex-US rights generates an additional $55M payment to PRTA.
This collaboration, which BMY inherited from CELG (#msg-139431013), potentially includes two drug candidates in addition to PRX005 (one targeting TDP-43 and one with an undisclosed target), but BMY has as yet opted in only for PRX005 and has shown no interest in the other two candidates, as far as I know.

Opdivo bests Adcetris in first-line-HL PFS—immature_OS_data_trending_in_favor_of_Opdivo:
https://www.fiercepharma.com/pharma/seagens-top-selling-drug-under-threat-bristol-myers-opdivo-beats-adcetris-lymphoma Compared with Adcetris, Bristol Myers Squibb’s Opdivo significantly reduced the risk of cancer progression or death by 52% [i.e. the HR for PFS was 0.48—Dew] in adults and children with newly diagnosed stage 3 or 4 classical Hodgkin lymphoma, according to phase 3 data unveiled at the 2023 American Society of Clinical Oncology annual meeting. Both drugs were used on top of the AVD regimen of chemotherapy.
The collaborative group-conducted trial, coded SWOG S1826, randomized nearly 1,000 patients. The results point to Opdivo-AVD as “a new standard of care that is better tolerated and results in a higher proportion of patients with durable remissions” than Adcetris-AVD, Oreofe Odejide, M.D., from the Dana-Farber Cancer Institute and an invited ASCO expert, said in a statement.
…Opdivo is currently only allowed in HL following Adcetris treatment thanks to an FDA accelerated approval in 2016. The new SWOG trial will support an FDA filing for Opdivo in front-line treatment, Herrera told Fierce Pharma in an interview. It could also help Bristol Myers turn the original conditional nod into a full approval.
…The Opdivo regimen has yet to show a significant patient survival benefit. By the data cutoff, 11 (2.2%) deaths happened in the Adcetris arm, compared with four (0.8%) for Opdivo. It will take a few years for the OS data from this trial to reach maturity.

BMY/JNJ unveil_phase-3_program_for Milvexian—50,000 patients_across_three_ trials_in secondary stoke prevention, ACS, and AF/primary stroke prevention:
https://www.businesswire.com/news/home/20230228006466/en Enrollment has begun for the Librexia STROKE trial, which is evaluating milvexian in addition to standard of care antiplatelet therapy for stroke prevention in patients after an acute ischemic stroke or high-risk transient ischemic attack. The Librexia ACS trial, which will evaluate event reduction in acute coronary syndromes in addition to standard of care antiplatelet therapy, and the Librexia AF trial, which will investigate milvexian compared to apixaban [Eliquis] in the prevention of stroke in patients with atrial fibrillation, will also initiate during the first half of 2023. Milvexian is an oral FXIa inhibitor. The phase-3 trial in secondary stroke prevention is at: https://www.clinicaltrials.gov/ct2/show/NCT05702034 .
The commercial impetus for the Milvexian program is to supersede Eliquis (BMY) and Xarelto (JNJ) when those drugs go off-patent or become subject to Medicare price-setting. The competition for Milvexian is Bayer’s Asundexian, another oral FXIa inhibitor that started a somewhat less aggressive phase-3 program (#msg-169841711) that does not have a trial for ACS.

Addendum—Breyanzi is the first CAR-T to show efficacy in CLL, as far as I know. rrCLL is a large market; if Breyanzi’s complete-response rate after, say, 5 years is as high as 15-20%, this indication could be a meaningful commercial contributor.
Breyanzi, which is currently approved for various forms of relapsed NHL, has annualized sales of under $200M.
