Cancer vaccine year: Merck/Moderna mRNA data reshapes oncology
STAT News flagged 2026 as one of the most consequential years in cancer treatment history, anchored by mRNA cancer vaccine data from Merck and Moderna that is drawing broad attention from investors and clinicians. The commentary, sourced from a subscriber newsletter by a STAT senior writer, reflects how the field's momentum around personalized neoantigen vaccines has shifted from speculative to increasingly credible. If the durability signal holds in larger datasets, the competitive and commercial implications for the broader oncology immunotherapy space — including PD-1 combinations and cell therapy — are material.
STAT News ↗mRNA cancer vaccines may be defining 2026 as oncology's most consequential year
A STAT News analysis by a senior biotech writer argues that 2026 is shaping up as one of the most consequential years in cancer treatment history, with Merck and Moderna's mRNA personalized cancer vaccine data driving much of the momentum.
Why it matters
The mRNA cancer vaccine story is moving from proof-of-concept into commercial and regulatory territory faster than most predicted; companies with competing approaches in therapeutic vaccines — or those positioned to be displaced by them in adjuvant settings — need to update their competitive assumptions now.
What to watch
Watch for Merck and Moderna to present updated overall survival data from the mRNA-4157/pembrolizumab Phase 3 melanoma program (KEYNOTE-942 follow-up) at ESMO 2026 or in a peer-reviewed publication, which would be the definitive test of durability.
Small molecule blocks CD28 costimulation selectively in IBD — without disrupting CTLA-4
Researchers using a NanoBiT split-luciferase screening platform identified a small molecule inhibitor that blocks CD28 costimulation (a signal required to fully activate T cells) while preserving CTLA-4 signaling, showing restraint of pathogenic T-cell responses in inflammatory bowel disease models.
Why it matters
Selective CD28 blockade has long been a theoretical goal in autoimmune drug development — this preprint provides preclinical proof of concept that a small molecule approach is feasible. Investors in IBD programs and companies developing next-generation costimulation blockers should note this as early-stage but directionally important science.
What to watch
Watch for follow-up in vivo efficacy and safety data in IBD animal models, and whether any biotech or pharma licenses this screening platform or advances a CD28-selective compound into IND-enabling studies.
Axsome Therapeutics
AXS-05 (dextromethorphan/bupropion) in Alzheimer's Disease Agitation
A Phase 3 randomized, double-blind, placebo-controlled study of AXS-05 in Alzheimer's disease agitation (NCT05557409) is now marked Completed on ClinicalTrials.gov. No efficacy or safety data have been disclosed in the registry update.
Why it matters
AXS-05's mechanism — NMDA receptor antagonism combined with dopamine/norepinephrine reuptake inhibition — offers a plausible rationale in agitation, but the registration completion without a data release creates uncertainty about whether results will be disclosed at a major neuroscience meeting or in a regulatory filing. Investors should not read completion as success.
What to watch
Watch for Axsome to disclose topline data from this Phase 3 study, likely at a CNS-focused medical meeting such as CTAD or AAN in late 2026 or early 2027, which would clarify the regulatory filing timeline.
Immunovant Sciences
Batoclimab in Graves' Disease
A Phase 2 proof-of-concept study evaluating batoclimab — an anti-FcRn antibody (a mechanism that reduces disease-causing IgG antibodies) — in Graves' disease patients who failed antithyroid therapy (NCT05907668) is now marked Completed on ClinicalTrials.gov. No efficacy or safety data have been released in the registry update.
Why it matters
Batoclimab's proof-of-concept completion in Graves' disease is a pipeline marker, not a verdict — the FcRn mechanism is biologically sound in an autoantibody-driven disease, but Immunovant needs to show a clean TSI (thyroid-stimulating immunoglobulin) reduction signal to justify further investment in a field where argenx already has FcRn momentum. The absence of a data press release is notable.
What to watch
Watch for Immunovant to release Phase 2 data from this Graves' disease study, likely presented at an endocrinology or autoimmune disease conference in H2 2026 or H1 2027, which will define whether a Phase 3 program is warranted.
Four Viridian Therapeutics trials for veligrotug (VRDN-001) in thyroid eye disease — including two Phase 3 efficacy studies (NCT05176639, NCT06021054), one Phase 3 safety/tolerability study (NCT06384547), and one open-label extension for non-responders (NCT06179875) — are now marked Completed on ClinicalTrials.gov. No efficacy or safety outcome data have been released in these registry updates.
Why it matters
The completion of multiple Phase 3 trials positions Viridian for a potential regulatory filing in TED, a market currently anchored by Amgen/Horizon's teprotumumab (Tepezza), but investors need actual outcome data before assessing competitive viability.
Analysis
Registry completions alone tell investors nothing about whether veligrotug beat the bar set by teprotumumab — the critical question is whether Viridian can show comparable or superior proptosis reduction with a differentiated dosing profile. The company's next move toward an NDA filing will depend entirely on what these completed datasets show.
What to watch
Watch for Viridian to announce a full data readout or regulatory filing submission from these completed Phase 3 trials, likely in late 2026 or early 2027.
A Phase 3 randomized, double-blind, placebo-controlled study of AXS-05 in Alzheimer's disease agitation (NCT05557409) is now marked Completed on ClinicalTrials.gov. No efficacy or safety data have been disclosed in the registry update.
Why it matters
Alzheimer's agitation is a large underserved indication with no FDA-approved treatments as of the trial's initiation; AXS-05 already carries FDA approval for major depressive disorder (Auvelity), giving Axsome a potential label expansion opportunity if Phase 3 data are supportive.
Analysis
AXS-05's mechanism — NMDA receptor antagonism combined with dopamine/norepinephrine reuptake inhibition — offers a plausible rationale in agitation, but the registration completion without a data release creates uncertainty about whether results will be disclosed at a major neuroscience meeting or in a regulatory filing. Investors should not read completion as success.
What to watch
Watch for Axsome to disclose topline data from this Phase 3 study, likely at a CNS-focused medical meeting such as CTAD or AAN in late 2026 or early 2027, which would clarify the regulatory filing timeline.
A Phase 2 proof-of-concept study evaluating batoclimab — an anti-FcRn antibody (a mechanism that reduces disease-causing IgG antibodies) — in Graves' disease patients who failed antithyroid therapy (NCT05907668) is now marked Completed on ClinicalTrials.gov. No efficacy or safety data have been released in the registry update.
Why it matters
Graves' disease represents a meaningful expansion opportunity for the anti-FcRn class beyond myasthenia gravis and CIDP; data from this proof-of-concept study will determine whether Immunovant pursues a Phase 3 program and how it competes with Argenx's broader FcRn franchise.
Analysis
Batoclimab's proof-of-concept completion in Graves' disease is a pipeline marker, not a verdict — the FcRn mechanism is biologically sound in an autoantibody-driven disease, but Immunovant needs to show a clean TSI (thyroid-stimulating immunoglobulin) reduction signal to justify further investment in a field where argenx already has FcRn momentum. The absence of a data press release is notable.
What to watch
Watch for Immunovant to release Phase 2 data from this Graves' disease study, likely presented at an endocrinology or autoimmune disease conference in H2 2026 or H1 2027, which will define whether a Phase 3 program is warranted.
A Phase 2 study of LY4100511, an oral IL-17A inhibitor developed by DICE Therapeutics (acquired by Lilly), in moderate-to-severe plaque psoriasis (NCT06602219) is now marked Completed on ClinicalTrials.gov. No efficacy or safety outcome data have been released in the registry update.
Why it matters
An oral IL-17A inhibitor, if validated, could disrupt a biologics-dominated psoriasis market and represents a key strategic asset from Lilly's $2.4B DICE acquisition — Phase 2 data will be the first real test of whether the small molecule approach can replicate biologic-level skin clearance.
Analysis
Lilly paid a substantial premium for DICE's oral IL-17 platform, and the Phase 2 completion puts data on the near-term horizon that will either validate or challenge the acquisition's strategic rationale. A clean PASI-75/90 signal would open a major oral option in a market still dominated by injectable biologics like secukinumab and ixekizumab.
What to watch
Watch for Lilly to disclose LY4100511 Phase 2 data — PASI response rates and safety profile — likely at the AAD or EADV dermatology meetings in late 2026 or early 2027, which will anchor the Phase 3 design decision.
A Phase 3 double-blind, placebo-controlled study of nirogacestat (a gamma-secretase inhibitor) in adults with desmoid tumor/aggressive fibromatosis (NCT03785964) is now marked Completed on ClinicalTrials.gov. No efficacy or safety outcome data are provided in the registry update; nirogacestat received FDA approval for desmoid tumors in November 2023 based on this program.
Why it matters
This registry completion likely reflects administrative closure of the trial that supported nirogacestat's approval; full publication of the dataset would provide the definitive efficacy and safety record for an already-approved drug in a rare, difficult-to-treat disease with few alternatives.
Analysis
With nirogacestat already on the market as Ogsiveo, this registry update is largely administrative — the commercial story now hinges on uptake in a small patient population and whether SpringWorks can expand the label or identify additional gamma-secretase inhibitor applications within the Merck KGaA portfolio.
What to watch
Watch for the full peer-reviewed publication of the DeFi Phase 3 dataset, which would provide the definitive progression-free survival and safety analysis supporting the approved label and informing any potential label expansion discussions.
Small molecule blocks CD28 costimulation selectively in IBD — without disrupting CTLA-4
Researchers using a NanoBiT split-luciferase screening platform identified a small molecule inhibitor that blocks CD28 costimulation (a signal required to fully activate T cells) while preserving CTLA-4 signaling, showing restraint of pathogenic T-cell responses in inflammatory bowel disease models.
Why it matters
Current B7-directed biologics like abatacept block both CD28 and CTLA-4, which can limit their utility in IBD; a selective CD28 inhibitor could achieve immunosuppression with a cleaner safety and tolerability profile, opening an oral small molecule pathway in a class currently dominated by biologics.
Analysis
Selective CD28 blockade has long been a theoretical goal in autoimmune drug development — this preprint provides preclinical proof of concept that a small molecule approach is feasible. Investors in IBD programs and companies developing next-generation costimulation blockers should note this as early-stage but directionally important science.
What to watch
Watch for follow-up in vivo efficacy and safety data in IBD animal models, and whether any biotech or pharma licenses this screening platform or advances a CD28-selective compound into IND-enabling studies.
Cryo-EM structures of TOP1-drug complexes reveal how eight cancer drugs trap a key enzyme
Cryo-EM structural analysis revealed how eight clinical anticancer drugs trap human topoisomerase 1 (TOP1) in a DNA-cleavage complex — a mechanism that kills cancer cells by preventing DNA repair — providing atomic-level detail of drug-enzyme interactions across the full clinical compound set.
Why it matters
Atomic-resolution structures of the TOP1 cleavage complex across eight drugs provide a structural template for rational design of next-generation TOP1 poisons with improved selectivity or reduced toxicity, potentially informing the next wave of antibody-drug conjugate (ADC) payloads that already rely on camptothecin-class TOP1 inhibitors.
Analysis
With TOP1 inhibitor payloads — particularly SN-38 and exatecan derivatives — now embedded in multiple approved and late-stage ADCs (including Enhertu and Trodelvy), structural insights that could guide next-generation payload optimization are commercially relevant, not just academically interesting. Companies building ADC pipelines should be watching this space.
What to watch
Watch for follow-on studies using these structural templates to design novel TOP1 poison scaffolds, and whether any ADC-focused biotechs cite this work in IND filings or platform presentations at the 2026 AACR or ESMO meetings.
mRNA cancer vaccines may be defining 2026 as oncology's most consequential year
A STAT News analysis by a senior biotech writer argues that 2026 is shaping up as one of the most consequential years in cancer treatment history, with Merck and Moderna's mRNA personalized cancer vaccine data driving much of the momentum.
Why it matters
If personalized neoantigen mRNA vaccines demonstrate durable recurrence-free survival benefit — particularly in adjuvant melanoma settings — it would validate a new category of cancer treatment and create a blueprint for expansion into other tumor types with high mutational burden.
Analysis
The mRNA cancer vaccine story is moving from proof-of-concept into commercial and regulatory territory faster than most predicted; companies with competing approaches in therapeutic vaccines — or those positioned to be displaced by them in adjuvant settings — need to update their competitive assumptions now.
What to watch
Watch for Merck and Moderna to present updated overall survival data from the mRNA-4157/pembrolizumab Phase 3 melanoma program (KEYNOTE-942 follow-up) at ESMO 2026 or in a peer-reviewed publication, which would be the definitive test of durability.
Oral GLP-1 competing directly with Lilly and Novo. Best-in-class efficacy in Phase 2 at ~15% weight loss. Phase 3 success could make Viking an M&A target.
