Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the impact of combining innate immune system activation (with IMSA101) with antigen release (through SAbR/PULSAR) on limited progressing lesions during ongoing adaptive immune system activation (with maintenance Nivo).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study expects to accrue the 15 patients over a 3-4 year period.

Patients with oligoprogressive disease (≤5 lesions) after treatment with Anti-PD1 / Anti-CTLA-4 will continue Anti-PD1 (nivolumab). All patients will have a mandatory PD-L1 PET (Pre-treatment and Week 12). All patients will undergo baseline biopsy (just before the administration of IMSA101 of the same lesion to be injected). SAbR will be delivered in 3 fractions at 12 Gy every 4 weeks (PULSAR regimen) to all progressing lesions. One lesion will also receive 3 intratumoral injections of IMSA101 (C1D1, C1D8, C1D15, C2D1, C3D1) immediately after radiation either on the same day or within 72 hours after the PULSE.

Selected Phase 2 dosing of IMSA101 (1200mcg) will be utilized.

At disease progression, patients have the option to undergo additional imaging and tissue/blood collections.
