Avviso - Le informazioni provengono da registri pubblici e potrebbero non riflettere i cambiamenti in tempo reale presso il centro locale.

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 refractory primary advanced hepatocellular carcinoma(HCC) . A total of 25 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.

Tipo: Experimental

Descrizione: 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.

Misure di Esito

Misure di Esito Primarie

Incidence of treatment-related AEsUp to 12 months since the initiation of treatment.

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.

Misure di Esito Secondarie

DORUp to 5 years since the initiation of treatment.

DOR is defined as the date of their first CR or PR (which is subsequently confirmed) to PD assessed by investigators, or death regardless of cause.

PFSUp to 5 years since the initiation of treatment.

PFS is defined as the time from the initiation of treatment to the date of PD assessed by investigators, or death any cause. Participants not meeting the criteria for progression by the analysis data cutoff date were censored at their last evaluable disease assessment date.

OSUp to 5 years since the initiation of treatment.

OS is defined as the time from the initiation of treatment to the date of death. Subjects who have not died by the analysis data cutoff date will be censored at their last contact date.

DCRUp to 2 years since the initiation of treatment.

DCR includes complete response (CR) ,partial response (PR) and stable disease (SD) defined by investigators according to Immune Response Evaluation Criteria in Solid Tumours (iRECIST) criteria or modified Response Evaluation Criteria in Solid Tumours (mRECIST) criteria.

ORRUp to 2 years since the initiation of treatment.

ORR includes CR and PR defined by investigators according to iRECIST or mRECIST criteria.

Quality of Life Assessment.Every 6 weeks up to 2 years since the initiation of treatment.

Quality of life will be evaluated by European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-Core 30 (C30) a core scale for all cancer patients, with a total of 30 items. Among them, items 29 and 30 are divided into seven levels. Based on the responses of the subjects, they are scored from 1 to 7 points. Other items are divided into four levels: never, a little, quite a bit, and a lot. When scoring, directly assign a score from 1 to 4 points.The researchers will assess changes in quality of life by calculating total scores.

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

Dynamics and molecular characteristics of CD8+ T cells with special phenotypes induced by PIN injection and its association with the treatment outcome. The relationship between the number of the CD8+ T cells and its anti-tumor effect was analyzed. To analyze the number and function of the CD8+ T cells in PB of patients with primary or acquired resistance after PIN injection and to summarize the key cellular and molecular mechanisms of resistance.

The level of cytokines and anti-PIN antibodies in serum .PB samples are collected at least on day 0 (before PIN injection), 2, 3 (before PIN injection) and 5 during each treatment cycle ( each cycle is 21 days).

The cytokines mainly include interleukin-1beta (IL-1β ) (pg / ml), IL-2(U/ml), IL-6(pg / ml),IL-10(pg / ml), tumor necrosis factor-α (TNF-α)(pg / ml), et al.
