Excited to announce the next step in my journey: I am joining the Solid Tumor GI Oncology Service @MSKCancerCenter! Deeply grateful to my colleagues, mentors, and fellows @Perlmutter_CC! Eager to dive into exceptional trials, clinical care, research, and education @MSKCC!

In this @OncJournal commentary, @EileenMOReilly and I highlight emerging preclinical evidence of synergy between RAS inhibition and RT in PDAC and make the case for prospective clinical trials evaluating this combination across the disease spectrum

A new vaccine continues to show potential as a ready-made treatment for pancreatic cancer, according to a study co-led by MSK researchers.
MSK's @EileenMOReilly presented phase 2 results from AMPLIFY-7P at #ESMO26. The vaccine targets KRAS mutations, which are found in more than 90% of pancreatic cancers.
99% of patients receiving the vaccine developed cancer-fighting immune T cells. Patients with the strongest immune responses had the lowest recurrence rates.
“Having a vaccine that’s ‘off-the-shelf’ would make it easier, faster, and less expensive to treat a larger number of patients,” says Dr. O’Reilly. “This gives hope for people with pancreatic cancer who have been out of effective treatments when their disease returns.” Learn more: bit.ly/3VSsO3h

Can KRAS-Targeted Immunotherapy Change Outcomes in Resected Pancreatic Cancer?
"Eileen O’Reilly, MD, of Memorial Sloan Kettering Cancer Center, reviews findings from the phase 2 AMPLIFY-7P trial evaluating camupepimut (ELI-002 7P) in resected KRAS-mutated pancreatic ductal adenocarcinoma (PDAC).
Dr. @EileenMOReilly discusses the significance of ctDNA status, the relationship between immune activation and clinical benefit, and how these findings may inform future phase 3 development of KRAS-targeted immunotherapy in pancreatic cancer."

PRABITAS phase III trial pragmatic trial enrolled 972 pts in 17M evaluating the schedule of TAS-102 + bev (2 weeks on/2 weeks off) vs. (1 week on/1 week off) which validates non-inferiority and less dose reductions validating our RWD approach in the US. #colorectal #cancer #ESMO2026 @OncoAlert

Interim analysis of HARMONi-GI1 phase III findings of #Ivonescimab (bispecific Ab for PD-1/VEGF) + chemo vs. durvalumab + chemo for treatment-naive #biliarytract #cancer (N=682). 👏👏
🔹Primary endpoint: OS of 14.9M vs. 12.1 (HR = 0.75)
🔹PFS: 8.4 vs. 5.8M; HR = 0.61
🔹ORR = 53.8% vs. 32.5%
🔹Subsequent therapies was 31.8% vs. 45.9% (more so in control arm)

Grateful to present 3 posters at #ESMO2026 in Madrid! 🇪🇸
1. Pathogenic germline ATM alterations define a distinct pancreatic cancer subtype with improved survival, less liver metastases and reduced KRAS signaling. @CentralParkWMD @EileenMOReilly @ciacobu @CpcrMsk
2. POSTN+ fibroblasts identify an aggressive tumor microenvironment and poorer survival in pancreatic cancer (#PRODIGE24). @RemyNicolle @cros_jerome
3. Early CT-derived body composition changes predict survival in biliary tract cancer patients receiving immunotherapy, independently of radiological progression, CA19-9, ECOG PS, and weight loss (#PRODIGE57). @DelayeMatthieu
Grateful to all collaborators at @MSKCancerCenter, @institut_curie, and GERCOR/PRODIGE!

PD(L)1-VEGF bispecifics are already beating PD1 inhibition alone in trials, so what's next?
This trial (BioNTech, DualityBio, BMS) adds a new B7-H3 ADC to a PDL1-VEGF bispecific, with potential synergy:
1) VEGF blockade: normalizes tumor vasculature, improves ADC delivery and T cell infiltration.
2) B7-H3 ADC: kills cancer cells, triggers immunogenic inflammation.
3) PDL1 blockade: releases immune suppression, allows T cells to exploit immune response induced by ADC.
Confirmed ORR up to 71% -- in immune-cold platinum-resistant ovarian cancer.
The broader, ongoing phase 2 includes colorectal cancer, pancreatic cancer and other tumor types.

#ESMO26 Day 1 highlight for me: MASTERPLAN, now in Lancet Oncology.
Radiation and pancreatic cancer have a complicated history. ESPAC-1 suggested adjuvant chemoradiation hurt. LAP07 and CONKO-007 couldn't show an OS benefit after chemo. A021501 closed its RT arm for futility. PREOPANC-2 was a draw. We walked through the adjuvant side of this story in Sem Rad Onc last year: doi.org/10.1016/j.semradonc.…
So why is MASTERPLAN different?
Phase 2, 14 sites in Australia and NZ (can i just say I love the Aus-NZ studies). 74 patients with high-risk localized PDAC, randomized 2:1 to chemo ± SBRT 40 Gy/5 after induction.
12-mo locoregional recurrence 20.2% vs 52.0%, sHR 0.44, p=0.022
PFS 11.9 vs 6.3 mo, HR 0.44
OS 22.0 vs 14.0 mo, HR 0.45
Grade ≥3 AEs 70% vs 64%.
Why did this one work when others didn't? The rad oncs can explain the physics better than I can. I just read it as better tumor zap zap.
Does it change practice? Maybe. I think we need to have a deeper conversation at every tumor board, but the juice seems worth the squeeze.

Some tentative good news today for a vaccine in pancreas cancer.
- 7-valent mutant KRAS vaccine (G12D, G12R, G12V, G12A, G12C, G12S and G13D) given after surgery and completion of chemotherapy (with or without radiotherapy) in patients with stage I-III KRAS-mutant pancreas cancer.
- This did not prevent recurrence in the overall population.
- But, when split into pre-specified groups: ctDNA+ vs. ctDNA-, or presence/absence of prior radiation, there was significant (and substantial) protection.
- It's unclear how this KRAS vaccine will interact with KRAS inhibitors in the future.
The vaccine is made by Elicio Therapeutics, the data were presented by Eileen O'Reilly at ESMO - it's now moving to phase 3.
fda.gov/drugs/resources-info… Congratulations to @AndreaCercek & Luis Diaz on their practice changing work, now finally reflected in an FDA approval for locally advanced rectal cancer. We are now curing these patients with limited toxicity. Lucky to have you as colleagues and mentors.

Preprint of one of my main postodoc projects over the last 5 years, mentored by @SantoshVardhana, which nominates inflammation-mediated iron deficiency as a metabolic bottleneck limiting anti-tumor CD8+ T cells immunity. Full tweetorial below by Santosh.
In our latest work, led by @schoenfeld_j, we explore one of the great enigmas of cancer biology: how systemic iron sequestration promotes tumor progression. 🧵

#daraxonrasib clinical outcomes by allele in #RASolute302 from FDA NDA review.
These data perpetuate unresolved questions:
- is RASi as effective for KRAS WT; K12R? See Table 24; Fig 11.
- is 300 mg necessary for maximal clinical benefit? no data provided comparing 200 vs 300.

🧵 1/10 The arc: POLAR - MDF – TIE
Pancreatic cancer is profoundly resistant to immune checkpoint inhibitors.
Yet, POLAR (pembrolizumab plus olaparib) trial showed that a subset of patients, especially with HRD (gBRCA2/1m or gPALB2m) tumors, can achieve remarkably durable control.
That led us to two questions:
#1 👆🏼what makes these tumors immunogenic?
#2 ✌️what makes that immunity actually work?
