No results posted yet for this study

Summary

In this single-center,open-label, phase I study, the safety and efficacy of PIN in combination with programmed cell death protein antibody (anti-PD1) therapeutic regimen will be evaluated in patients with late-stage advanced solid tumors . A total of 20 to 30 patients are planned to be enrolled and receive PIN plus anti-PD1 combined treatment. It aims to: 1).assess the safety and antitumor effects of the above combined treatment regimen. 2).detect the dynamic changes and molecular characteristics of PIN-induced CD8+ T cells with special phenotype in peripheral blood (PB) and transformation of tumor microenvironment (TME) after the treatment with PIN. 3).evaluate the immunological or clinical predictive biomarkers for toxicity and efficacy.

BIOLOGICAL

PIN +anti-PD1

1. Initial treatment phase: PIN injection frequency: day0 and day 3, per 3 weeks for 8 cycles; PIN injection dosage: Cycle1: 4e9 or 8e9 viral particles of PIN based on the number of injectable lesions, their longest diameter, and the tumor volume capacity . Cycle 2\~8: 4e9 or 8e9 viral particles of PIN based on the tumor volume's capacity. Anti-PD1: day -3, per 3 weeks for 8 cycles; 2. Maintenance treatment phase: No injection lesion: Anti-PD1: day 1, per 3 weeks till 2 years unless PD or serious intolerable AEs. Have injection lesion: PIN: 4e9 or 8e9 viral particles based on the tumor volume's capacity, per 6 weeks (within first 24 weeks), then per 8 weeks till 2 years unless unavailability of injection lesion, PD or serious intolerable AEs. Anti-PD1: day 1, per 3 weeks till 2 years unless PD or serious intolerable AEs. 3. Salvage treatment phase: Dosage and frequency of administration refer to the initial treatment phase and maintenance treatment phase.
