Brief 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.

Outcome Measures

Primary Outcomes (1)

• Incidence of treatment-related AEs

  Treatment-related AEs are defined as any adverse medical events occurring since the initiation of treatment and grading these toxicities by Common Terminology Criteria for Adverse Events (CTCAE) V5.0.

  Up to 12 months since the initiation of treatment.

Secondary Outcomes (6)

• DCR

  Up to 2 years since the initiation of treatment.

• ORR

  Up to 2 years since the initiation of treatment.

• DOR

  Up to 5 years since the initiation of treatment.

• PFS

  Up to 5 years since the initiation of treatment.

• OS

  Up to 5 years since the initiation of treatment.

Other Outcomes (2)

• Immunological response

  PB samples are collected at least on days 0 (before PIN injection), 2, 3 (before PIN injection) and 5 during each treatment cycle ( (each cycle is 21 days)).

• The level of cytokines in serum

  PB samples are collected at least on days 0 (before PIN injection), 2, 3 (before PIN injection) and 5 during each treatment cycle ( (each cycle is 21 days)).

Study Arms (1)

Arm: PIN+anti-PD1

EXPERIMENTAL

1. Initial treatment phase: The combined treatment of PIN and anti-PD1 will be administered for 8 cycles; Unless PD or serious intolerable AEs. 2. Maintenance treatment phase: For patients who completed 8 cycles treatment and obtained effective disease control, if residual tumor lesions are still accessible for local injection, combination therapy will be continued. If no injectable lesion, anti-PD1 will be administrated per 3 weeks till 2 years unless PD or serious intolerable AEs. 3. Salvage treatment phase: For patients who experience disease recurrence or progression 16 weeks after ceasing PIN injection, if there are accessible lesions available for PIN injection, combination therapy will be resumed. If specific T cells induced by PIN can be detected in PB when there is no injectable lesion, then the specific T cells are amplified and transfused for salvage therapy.

Biological: PIN +anti-PD1

Interventions

PIN +anti-PD1 BIOLOGICAL

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.
