Cancer vaccine era arrives: Merck/Moderna mRNA data reshapes oncology
According to STAT News, the mRNA cancer vaccine collaboration between Merck and Moderna has produced data compelling enough that analysts are calling 2026 one of the most consequential years in cancer treatment history. The individualized neoantigen vaccine approach — which trains the immune system to recognize each patient's unique tumor mutations — appears to be crossing from experimental concept to clinical reality. If durability holds, this platform could redefine adjuvant treatment across multiple tumor types and threaten the dominance of standard checkpoint inhibitor monotherapy.
STAT News ↗Axsome Therapeutics
AXS-05 (dextromethorphan-bupropion) in Agitation in Alzheimer's disease
The Phase 3 trial (NCT05557409) has completed per ClinicalTrials.gov registry update. Full efficacy and safety data have not yet been released in the source material.
Why it matters
Completion of this Phase 3 trial is the pivotal event that will determine whether Axsome can file an NDA and compete in the Alzheimer's agitation market currently targeted by Acadia's pimavanserin. The investment thesis hinges on what the full data show, and the absence of any disclosed numbers means the market is flying blind until a press release or conference presentation.
What to watch
Watch for Axsome's topline press release, expected in the near term following registry completion, and whether they announce a target NDA submission date.
Viridian Therapeutics
Veligrotug (VRDN-001) in Thyroid eye disease (TED)
Multiple Phase 3 studies of veligrotug in thyroid eye disease — including both active and chronic TED and an open-label extension for non-responders — are now marked Completed on ClinicalTrials.gov (NCT05176639, NCT06021054, NCT06384547, NCT06179875). No efficacy or safety data have been released in the source material.
Why it matters
Four simultaneous Phase 3 completions in TED is a significant portfolio moment for Viridian, but the complete absence of disclosed outcome data means investors cannot yet assess differentiation from teprotumumab on efficacy or tolerability. The next disclosure event will be the first real test of whether the IGF-1R antibody approach delivers competitive response rates and durability.
What to watch
Watch for Viridian's topline data announcement across these programs and any indication of a BLA filing timeline, likely to be disclosed at a major ophthalmology or endocrinology conference in late 2026.
Eli Lilly and Company (DICE Therapeutics)
LY4100511 (DC-853) in Moderate-to-severe plaque psoriasis
The Phase 2 study of LY4100511 (DC-853), an oral IL-17 inhibitor from DICE Therapeutics (acquired by Lilly in 2023), in moderate-to-severe plaque psoriasis (NCT06602219) is now marked Completed on ClinicalTrials.gov. No efficacy or safety data have been released in the source material.
Why it matters
This completion validates Lilly's rationale for the $2.4B DICE acquisition, but the Phase 2 data — when disclosed — will be the first real test of whether the oral IL-17 approach achieves the skin clearance rates (PASI 90/100) needed to compete with injectable standards of care. A strong signal here would reframe Lilly's immunology pipeline beyond GLP-1.
What to watch
Watch for Lilly to disclose LY4100511 Phase 2 efficacy data at a dermatology meeting such as AAD or EADV in late 2026 or early 2027, which would set the bar for a potential Phase 3 go/no-go decision.
Selective CD28 costimulation blocker shows efficacy in IBD without disabling CTLA-4
Researchers identified a small molecule that selectively blocks CD28 costimulation — the signal T cells need to become fully activated — in inflammatory bowel disease models, without simultaneously impairing CTLA-4 signaling, a key limitation of existing biologic approaches like abatacept.
Why it matters
The IBD market is hungry for mechanisms beyond IL-23 and JAK inhibitors, and a selective CD28 blocker could carve out a niche in refractory patients — but this is early-stage bioRxiv preprint data, and the path from NanoBiT screening hits to an IND is long. Companies with existing T-cell biology platforms in autoimmune disease should be watching.
What to watch
Watch for this group or a licensing partner to file an IND application; the key next step is demonstrating selectivity and safety in primate models before any human proof-of-concept study.
The Phase 3 trial (NCT05557409) has completed per ClinicalTrials.gov registry update. Full efficacy and safety data have not yet been released in the source material.
Why it matters
AXS-05 is Axsome's lead asset with blockbuster potential in Alzheimer's agitation — a large, underserved indication with no FDA-approved oral option — making this readout commercially critical.
Analysis
Completion of this Phase 3 trial is the pivotal event that will determine whether Axsome can file an NDA and compete in the Alzheimer's agitation market currently targeted by Acadia's pimavanserin. The investment thesis hinges on what the full data show, and the absence of any disclosed numbers means the market is flying blind until a press release or conference presentation.
What to watch
Watch for Axsome's topline press release, expected in the near term following registry completion, and whether they announce a target NDA submission date.
Multiple Phase 3 studies of veligrotug in thyroid eye disease — including both active and chronic TED and an open-label extension for non-responders — are now marked Completed on ClinicalTrials.gov (NCT05176639, NCT06021054, NCT06384547, NCT06179875). No efficacy or safety data have been released in the source material.
Why it matters
Viridian is competing directly with Amgen's teprotumumab (Tepezza) in TED; a full data package from these trials will determine whether veligrotug can challenge the established standard of care.
Analysis
Four simultaneous Phase 3 completions in TED is a significant portfolio moment for Viridian, but the complete absence of disclosed outcome data means investors cannot yet assess differentiation from teprotumumab on efficacy or tolerability. The next disclosure event will be the first real test of whether the IGF-1R antibody approach delivers competitive response rates and durability.
What to watch
Watch for Viridian's topline data announcement across these programs and any indication of a BLA filing timeline, likely to be disclosed at a major ophthalmology or endocrinology conference in late 2026.
The Phase 3 trial of nirogacestat in desmoid tumor/aggressive fibromatosis (NCT03785964) is now marked Completed on ClinicalTrials.gov. No efficacy or safety outcomes are disclosed in the source material.
Why it matters
Nirogacestat received FDA approval for desmoid tumors in November 2023; this trial completion likely reflects the end of the pivotal study follow-up period and may feed into post-marketing commitments or label update submissions.
Analysis
With nirogacestat already approved, this registry completion is less about clinical uncertainty and more about whether longer-term follow-up data will solidify durability claims and support expanded use — both critical for maintaining pricing power in this rare tumor setting.
What to watch
Watch for any updated efficacy or survival data from this study presented at ASCO or ESMO 2027, which could inform label discussions with FDA on long-term outcomes.
The proof-of-concept Phase 2 study of batoclimab in Graves' disease (NCT05907668) is now marked Completed on ClinicalTrials.gov. No efficacy or safety data have been released in the source material.
Why it matters
Immunovant is developing batoclimab — an FcRn inhibitor that lowers pathogenic IgG antibodies — across multiple autoimmune indications; Graves' disease data would expand the competitive case against Argenx's efgartigimod and UCB's rozanolixizumab.
Analysis
Completion of this proof-of-concept study is a key inflection point for Immunovant's indication expansion strategy; what investors need to see is whether batoclimab can durably suppress TSH-receptor antibodies enough to achieve thyroid hormone normalization, a bar that would distinguish it in the FcRn crowded field.
What to watch
Watch for Immunovant to disclose proof-of-concept data at an endocrinology meeting or in a company press release in H2 2026, which could support a Phase 3 decision.
The Phase 2 study of LY4100511 (DC-853), an oral IL-17 inhibitor from DICE Therapeutics (acquired by Lilly in 2023), in moderate-to-severe plaque psoriasis (NCT06602219) is now marked Completed on ClinicalTrials.gov. No efficacy or safety data have been released in the source material.
Why it matters
An oral IL-17 inhibitor that matches injectable biologics would be a significant commercial advance in psoriasis, a multi-billion-dollar market currently dominated by Novartis's secukinumab and Eli Lilly's own injectable ixekizumab.
Analysis
This completion validates Lilly's rationale for the $2.4B DICE acquisition, but the Phase 2 data — when disclosed — will be the first real test of whether the oral IL-17 approach achieves the skin clearance rates (PASI 90/100) needed to compete with injectable standards of care. A strong signal here would reframe Lilly's immunology pipeline beyond GLP-1.
What to watch
Watch for Lilly to disclose LY4100511 Phase 2 efficacy data at a dermatology meeting such as AAD or EADV in late 2026 or early 2027, which would set the bar for a potential Phase 3 go/no-go decision.
Selective CD28 costimulation blocker shows efficacy in IBD without disabling CTLA-4
Researchers identified a small molecule that selectively blocks CD28 costimulation — the signal T cells need to become fully activated — in inflammatory bowel disease models, without simultaneously impairing CTLA-4 signaling, a key limitation of existing biologic approaches like abatacept.
Why it matters
A CD28-selective inhibitor could deliver the T-cell suppression needed to quiet gut inflammation while preserving the CTLA-4 immune checkpoint brake, potentially offering a cleaner safety profile than current biologics and a new oral or injectable option for IBD patients who fail anti-TNF or anti-integrin therapy.
Analysis
The IBD market is hungry for mechanisms beyond IL-23 and JAK inhibitors, and a selective CD28 blocker could carve out a niche in refractory patients — but this is early-stage bioRxiv preprint data, and the path from NanoBiT screening hits to an IND is long. Companies with existing T-cell biology platforms in autoimmune disease should be watching.
What to watch
Watch for this group or a licensing partner to file an IND application; the key next step is demonstrating selectivity and safety in primate models before any human proof-of-concept study.
Cryo-EM maps reveal how eight cancer drugs trap topoisomerase 1 — with drug design implications
High-resolution cryo-EM structures of human topoisomerase 1 (TOP1, an enzyme that untangles DNA during replication) trapped by eight clinical anticancer drugs reveal the precise molecular interactions that drive cytotoxicity, showing both shared and drug-specific binding features.
Why it matters
Understanding exactly how camptothecin-class drugs and others stabilize the TOP1-DNA cleavage complex at atomic resolution provides a rational blueprint for designing next-generation TOP1 poisons with improved potency, reduced toxicity, or activity against resistance mutations — relevant for ADC (antibody-drug conjugate) payload development as well as standalone small molecules.
Analysis
For ADC developers using TOP1 inhibitor payloads — including companies relying on DXd-based linkers — this structural dataset could accelerate payload optimization and help differentiate next-generation ADC programs on tolerability and tumor penetration. It's basic science, but the commercial application is direct.
What to watch
Watch for follow-on studies using these structures to design novel TOP1 poison analogs with reduced off-target toxicity, and whether any biotech licenses this structural work to advance ADC payload pipelines.
Small catechol derivative targets IKKβ to block bone-destroying osteoclast activity
Computational and experimental analysis found that 4-methylcatechol inhibits IKKβ — a key enzyme in the NF-κB signaling pathway that drives osteoclast (bone-resorbing cell) formation — through both non-covalent and quinone-mediated covalent mechanisms, reducing pathological bone loss in cell models.
Why it matters
IKKβ inhibition as a bone-protective strategy has been difficult to prosecute due to systemic immune suppression risks; the dual covalent/non-covalent mechanism of this catechol derivative raises the possibility of a locally acting or tumor-microenvironment-targeted approach for osteolytic metastases or osteoporosis.
Analysis
This is mechanistically interesting for companies developing bone protection in oncology — particularly those targeting RANKL/NF-κB crosstalk — but covalent small molecules in this pathway carry selectivity risk, and the jump from computational modeling to in vivo validation is substantial. Near-term drug development impact is limited.
What to watch
Watch for in vivo bone loss model data from this or related groups that would validate the IKKβ-targeting approach as a standalone or combination strategy worth advancing toward preclinical IND-enabling studies.
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.
