Abstract

2523 Background: T-cell targeting of mutation-derived epitopes (neoantigens) has been demonstrated to drive anti-tumor responses. Immunizing patients against such neoantigens in combination with a checkpoint inhibitor (CPI) may elicit greater anti-tumor responses than CPI alone. Mutations are rarely shared between patients, thus requiring a personalized approach to vaccine design. Methods: A phase I dose escalation study of mRNA-4157 as adjuvant monotherapy in patients with resected solid tumors (melanoma, bladder carcinoma, HPV negative HNSCC, NSCLC, SCLC, MSI-High, or TMB High cancers) and in combination with pembrolizumab in patients with advanced or metastatic cancer is being conducted to evaluate safety. mRNA-4157 is a lipid encapsulated personalized vaccine encoding multiple neoantigens selected using a proprietary algorithm designed to induce neoantigen specific T cells and associated anti-tumor responses. Patients may receive up to 9 cycles (Q3W) of mRNA-4157 by intramuscular injection (0.04 – 1 mg). In the combination arm, pembrolizumab (200 mg) is administered for two cycles prior to combination with mRNA-4157; patients may continue pembrolizumab after completion of 9 cycles of combination therapy. Primary end points include safety, tolerability, and recommended phase 2 dose. Results: 33 patients received mRNA-4157; 13 as monotherapy and 20 in combination with pembrolizumab. No DLTs were reported, and treatment related AEs have generally been of low grade and reversible, and no drug related SAEs or AEs ≥ grade 3 have been observed. Of the 13 patients on adjuvant monotherapy (3 melanoma, 8 NSCLC, 2 MSI-High), 12 patients remain disease free on study, median follow-up of 8 months. 20 patients have been treated in combination (1 TMB-high, 4 bladder, 2 HNSCC, 1 melanoma, 7 NSCLC, 2 SCLC, 3 MSI-high), 12 had progressed on prior CPI, 16 have been restaged and there are 1 CR (on pembrolizumab prior to vaccination), 2 PR, 5 SD for at least 5 combination cycles, 5 PD, 2 iuPD, and 1 patient is non-evaluable for response but remains on study. Neoantigen specific T cell responses have been detected by IFN-γ ELISpot from PBMCs. Conclusions: mRNA-4157 is safe and well tolerated at all dose levels tested. Clinical responses have been observed in combination with pembrolizumab and neoantigen-specific T cells have been induced, supporting the advancement of mRNA-4157 to phase 2. Clinical trial information: NCT03313778.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
