Varegacestat FDA Regulatory Events
Varegacestat is a drug developed by Immunome for the following indication: Patients with Desmoid Tumors.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- varegacestat
- Announced Date:
- April 29, 2026
- Indication:
- Patients with Desmoid Tumors
Announcement
Immunome, Incannounced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for varegacestat, an investigational, oral, once-daily gamma secretase inhibitor (GSI), for the treatment of adults with desmoid tumors.
AI Summary
Immunome announced it submitted a New Drug Application to the U.S. FDA for varegacestat, an investigational oral gamma secretase inhibitor for adults with progressing desmoid tumors. The NDA is supported by positive results from the Phase 3 RINGSIDE trial.
In an exploratory analysis, varegacestat showed a median best change in tumor volume of −83% versus +11% with placebo by blinded review. The trial met all key secondary endpoints, with statistically significant improvements in landmark tumor volume reduction and worst pain intensity.
Varegacestat was generally well tolerated, with a safety profile consistent with the GSI class. Common adverse events included diarrhea (82%), fatigue (44%), rash (43%), nausea (35%) and cough (34%), mostly grade 1–2. RINGSIDE data will be presented at ASCO 2026.

IM-1021 FDA Regulatory Events
IM-1021 is a drug developed by Immunome for the following indication: In Cancer therapies.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- IM-1021
- Announced Date:
- October 23, 2025
- Indication:
- In Cancer therapies
Announcement
Immunome, Inc recently presented preclinical data showing its proprietary antibody-drug conjugate (ADC) payload HC74 overcomes multiple mechanisms of ADC resistance, including payload efflux and target heterogeneity.
AI Summary
Immunome, Inc., a biotech company, recently presented preclinical results showing its new antibody-drug conjugate payload HC74 can bypass common ADC resistance mechanisms. HC74, a topoisomerase I inhibitor, avoids drug efflux by transporters like ABCC1 and ABCB1 and shows strong membrane permeability. This leads to enhanced cancer-cell killing and bystander effects. In multiple tumor models, including colorectal cancer resistant to trastuzumab-DXd and irinotecan, ADCs with HC74 demonstrated significant efficacy. They also worked in tumors with acquired resistance to trastuzumab-DXd and in non-small cell lung cancer with uneven target expression. The data were shared in October 2025 at the AACR-NCI-EORTC International Conference in Boston. HC74 serves as the payload in IM-1021, a ROR1-targeted ADC in Phase 1 trials. These findings support HC74’s potential as a best-in-class ADC payload.

- IM-1021
- Announced Date:
- March 10, 2025
- Indication:
- In Cancer therapies
Announcement
Immunome, Inc. announced that the first patient has been dosed in the Phase 1, first-in-human trial of IM-1021, a ROR1-targeted ADC.
AI Summary
Immunome, Inc. has reached an exciting milestone by dosing the first patient in its Phase 1, first‐in‐human trial of IM-1021, a ROR1-targeted antibody-drug conjugate (ADC). This trial is designed to evaluate the safety, tolerability, and preliminary anti-tumor activity of IM-1021. The study will enroll patients with advanced B-cell lymphomas and solid tumors, aiming to address a significant unmet medical need.
IM-1021 uses Immunome’s proprietary TOP1 inhibitor, HC74, to target cancer cells by homing in on the ROR1 protein. This innovative approach could potentially improve treatment outcomes for patients with difficult-to-treat cancers. As the trial progresses, researchers will closely monitor how the drug performs in patients, focusing on its dosing, pharmacokinetics, and effectiveness, which marks a notable step forward in the field of targeted cancer therapies.
