“Topline ESMO data from INTerpath-001 (#Moderna's personalized cancer vaccine) reportedly leaked elsewhere: RFS HR 0.58 (Honestly shame on people for breaking embargo’s). There is a huge divide here between physicians and non-physicians on the outcome. To me, this was huge and clearly worked. This hazard ratio puts it in the company of the most paradigm-changing adjuvant trials in oncology history. Yes, the same outcome can be generated from giving pembro in the neoadjuvant space [SWOG S1801 neoadjuvant + adjuvant pembro vs adjuvant pembro alone: EFS HR 0.58.] That isn't the point. A peptide vaccine strategy yielded the same outcome as having a tumor in vivo. This demonstrates the tech worked, now it can be applied more broadly or potentially even supercharge the neoadjuvant space with less immunogenic tumors. Time to do better and apply to more things (like colon cancer pls).”

And yes, it’s clearly positive: 📉 RFS HR 0.58 📉 DMFS HR 0.62 But here’s the uncomfortable part: SWOG S1801 also reported an HR 0.58…simply by moving 3 doses of pembrolizumab BEFORE surgery… ☝🏼Not the same population. Not the same endpoint. Not a cross-trial comparison. Still, in 2026, should a personalized mRNA vaccine really be benchmarked against adjuvant pembro alone? Before calling this a new standard, I want to see the vaccine face the NEOADJUVANT era. Same HR. Different path. And that may be the real INTerpath question 👀”

“Cautionary note – personalized mRNA neoantigen vaccine (intismeran / mRNA-4157) in resected melanoma. The reported reduction in recurrence is real, yet several core uncertainties remain unresolved. The control was an inactive placebo, not a scrambled or irrelevant mRNA matched for mass and antigen number. Non-specific innate effects of the mRNA-LNP platform therefore cannot be separated from antigen-specific activity. No published in vitro data have tested whether the encoded neoantigen peptides or mRNA constructs exert any direct stimulatory or pro-proliferative effect on melanoma cells independent of the immune system. This possibility has not been experimentally excluded. Overall survival benefit is still immature, and the contribution of the vaccine outside the adjuvant Keytruda combination is unproven. Manufacturing time, cost, and scalability constraints are substantial; generalizability beyond highly selected resected melanoma remains limited. These open questions do not erase the clinical signal. They do limit how confidently the mechanism and the true incremental value of the personalized neoantigens can be asserted.”

“Some thoughts on the INTerpath-001 backlash, and the simplistic "neoadjuvant already does better, so why bother" take. I think it misses a few important things. ➡️ First, the neoadjuvant data (S1801, NADINA) come from patients with macroscopic, clinically detectable nodal disease. INTerpath-001 also includes node-negative IIB/IIC and patients whose nodal disease only showed up on sentinel node biopsy. In the big SLN trials, about two thirds of SLN+ patients had deposits ≤1 mm. None of these patients are neoadjuvant candidates. We see the same confusion in #NSCLC all the time, when people compare stage IIIA from adjuvant trials (pathological staging) with stage IIIA from neoadjuvant trials (clinical staging). Same stage on paper, not the same patients. ➡️ Second, INTerpath-001 was designed before NADINA read out, when adjuvant anti-PD-1 was still the default for resected stage III. Judging it against today's practice is a bit of hindsight. ➡️ Third, I suspect the most logical place for a neoantigen vaccine is after neoadjuvant ICI in patients who don't reach pCR. INTerpath-009 is already testing exactly this in NSCLC, so we'll get some hints there. ➡️ And all of this comes with only an absolute ~3% increase in grade ≥3 toxicity, which also belongs in the balance. For macroscopic stage III, the critique lands. I want to see the full data and the stage breakdown at LBA1. But I'd be careful firing at this result before we've even seen it properly.”

There has been considerable discussion about the discordant results of the recent phase III trials evaluating BCG + immune checkpoint blockade. But I think we're overlooking a potentially important difference between these trials, one that could have major implications for how we interpret the results and counsel our patients. POTOMAC and CREST were positive trials, but unlike the negative ALBAN trial, both permitted enrollment of patients previously treated with BCG. To my knowledge, neither has reported how many patients had prior BCG exposure or whether the benefit of adding checkpoint blockade differs between previously treated and truly BCG-naïve patients.

New EHA follicular lymphoma guidelines place R2 ± tafasitamab or epcoritamab ahead of immunochemotherapy from first relapse (per @HayderSaeed_MD).

“Legend Biotech has received FDA IND clearance for LB2501, an investigational in vivo CAR-T therapy designed to generate CD19/CD20 dual-targeting CAR-T cells directly inside the patient after a single infusion. Unlike conventional autologous CAR-T, LB2501 is designed to be off-the-shelf, potentially eliminating several steps of individualized cell collection and manufacturing. Notably, the planned U.S. Phase 1/2 study will evaluate the therapy without lymphodepleting chemotherapy. LB2501 uses Legend’s TaVec™ platform, an engineered, replication-incompetent lentiviral vector designed to selectively transduce T cells in vivo. The resulting CAR-T cells target both CD19 and CD20—a strategy intended to reduce the risk of antigen escape in B-cell malignancies. If successful, this could address some of the biggest barriers to conventional CAR-T: manufacturing time, complexity, scalability, and access. But the critical questions now move from engineering to the clinic: Can we reliably generate enough functional CAR-T cells in vivo? Will the cells expand and persist appropriately? What will the safety profile look like without traditional lymphodepletion? And can dual targeting translate into deeper and more durable responses? LB2501 is now moving toward U.S. clinical evaluation, adding another important step in the rapidly developing field of in vivo cell engineering. The next generation of CAR-T may not be manufactured for the patient—it may be manufactured inside the patient.”
