WSJ Defends Replimune Drug Amid Mounting Criticism

@WSJ is not giving up the fight for Replimune's cancer drug. Second CRL draws another rebuke and a direct attack on @MartyMakary (Prasad gets another swipe as well, but he's about out the door now.) I often disagree with the...

Trump Targets NIH Funding Amid $1.5T War Spend

Trump once again going for draconian cuts to NIH, though not as catastrophic as he sought for the last round (and didn't get). Meanwhile, he wants $1.5T for war. I doubt he'll be any more successful with NIH cuts than...

Insurers' AI Denials Delay Life‑saving Cancer Care

The mother of an angiosarcoma patient reached out this weekend to see if I could help her daughter get a second opinion at Dana-Farber after it was rejected by her insurer. I'll do what I can. Dana-Farber has made a...

In‑vivo CAR‑T Achieves 4/5 MRD‑Negative Remissions

Outstanding piece here from @leilei_wuu on AstraZeneca's in vivo CAR-T for multiple myeloma. There's data on 5 patients, which is pretty lean, but 4 come out MRD negative in two months, which is extraordinary. We're going to see a lot...

Pfizer's Lyme Vaccine Data Remains Ambiguous, FDA Review Looms

As someone who lived in Vermont and still spends the summer there, it's disappointing to see the ambiguity in Pfizer's data on a new Lyme disease vaccine. It's a serious threat. Now we can move on to speculating on the...

I'm biased, of course, but hats off to the @FT for some truly groundbreaking work on the Iran war. Ed Luce's commentary has been essential to understanding the dilemma Europe finds itself in as its leaders try to edge away...

Merkel cell carcinoma log, day #594. Yesterday, I was at Dana-Farber for my first infusion of avelumab in more than 3 months. Aside from two botched blood tests — the buzz is the blood tests are being done with recently...

Healthcare Costs Forcing Debt, Hunger, and Retirement Delays

Such a dismal conclusion. Taking on debt, skipping meals, delaying retirement, etc, etc, in order to cover healthcare costs. When does America come to grips with healthcare costs? Something has to give. https://t.co/L48u4W2CDG

BioNTech Founders Launch New Biotech, Eye FDA Acceptance

Sticking with the science. I find that really impressive. BioNTech founders Uğur Şahin and Özlem Türeci are leaving the biotech they founded to start a new one. Maybe by the time they have something for the clinic, the FDA will...

Senior FDA Official’s Attack Sparks Debate Over Leadership
