TQB2618 Injection Combined With Penpulimab Injection in the Treatment of Patients With Recurrent/Metastatic Nasopharyngeal Carcinoma

A Phase II Clinical Trial to Evaluate the Efficacy and Safety of TQB2618 Injection Combined With Penpulimab in Patients With Recurrent/Metastatic Nasopharyngeal Carcinoma

This study consists of two parts:

Part 1 encompasses a safety lead - in phase and an expansion phase. In both phases, subjects with advanced nasopharyngeal carcinoma who have previously failed platinum - based chemotherapy and immune checkpoint inhibitors (such as anti - PD - 1 monoclonal antibodies/anti - PD - L1 monoclonal antibodies, etc.) will be enrolled. The treatment regimen is TQB2618 combined with penpulimab. During the safety lead - in phase, it is to explore whether two dosage groups of TQB2618 in combination with penpulimab (1200mg/1500mg) are safe and tolerable. If both dosage groups are tolerable, in the expansion phase, an additional 18 to 24 subjects will be enrolled to receive TQB2618 (1500mg) + penpulimab (200mg). If the high dosage (1500mg) of TQB2618 is not tolerated, all subjects will receive TQB2618 (1200mg) + penpulimab (200mg).

Part 2 also includes a safety lead - in phase and an expansion phase. It enrolls treatment - naïve subjects with advanced nasopharyngeal carcinoma who have not received prior systemic treatment. These subjects will receive TQB2618 + penpulimab + GP chemotherapy, with the dosage of TQB2618 being 1200mg. In the safety lead - in phase, 3 to 6 subjects will be enrolled. If the treatment combination is safe and tolerable, then in the expansion phase, an additional 24 to 27 subjects will be enrolled.

Both parts of the study will be carried out simultaneously

Study Overview

• Status: Completed
• Conditions: Nasopharyngeal Carcinoma
• Intervention / Treatment: Drug: TQB2618 injection; Penpulimab injection; Drug: TQB2618 Injection, Pempulimab Injection, Cisplatin Injection, Gemcitabine Hydrochloride Injection

Detailed Description

This study is divided into two parts:

The first part includes the safe introduction phase and the expansion phase. All the patients with advanced nasopharyngeal carcinoma who failed to be treated with platinum chemotherapy and immunocheckpoint inhibitors (anti-PD-1 monoclonal antibody/anti-PD-L1 monoclonal antibody, etc.) were enrolled. The treatment scheme is TQB2618 + Penpulimab Injection. During the safe introduction period, we explored whether the two dose groups (1200mg/1500mg) were safe and tolerable when TQB2618 was combined with Penpulimab Injection. If the two dose groups are tolerable, 18~24 patients in the second phase of the extended study were randomized to receive TQB2618 in two dose groups (1200mg/1500mg)+Penpulimab Injection (200mg) at a ratio of 1:1. If high dose (1500mg) of TQB2618 is not tolerated, all patients will receive TQB2618 (1200mg)+Penpulimab Injection (200mg).

The second part is a randomized controlled study design, which is divided into two groups. All the newly treated patients with advanced nasopharyngeal carcinoma who have not received systematic treatment in the past received TQB2618+Penpulimab Injection+GP chemotherapy and paianzulimab+GP chemotherapy respectively. The dose of TQB2618 was 1200mg.

The two parts of research are carried out at the same time.
