Study Details

Study Description

Brief Summary

There is increasing evidence that combination therapy with nanoparticle albumin-bound paclitaxel (nab-paclitaxel) and programmed cell death protein 1 (PD-1) inhibitor is safe and efficacious in treating many types of malignant tumors. However, clinical data demonstrating the effect of this treatment combination for patients with metastatic soft tissue sarcoma are currently limited.

In this open, single center, one- armed clinical study, enrolled patients will receive the following treatment: 300 mg/m2 of nab-paclitaxel (Hengrui Pharmaceutical, Lianyungang, China) and 200 mg of PD-1 inhibitor (camrelizumab; Hengrui Pharmaceutical, Lianyungang, China) via a 30-min intravenous infusion on day 1. The treatment was repeated every three weeks until progressive disease occurrence or unacceptable adverse events.

The primary end point was progression-free survival at 4 months. Secondary objectives were objective response rate and safety.

Outcome Measures

Primary Outcome Measures

Progression-free survival [Up to approximately 24months]
Progression-free survival is defined as time from enrollment to the first occurrence of progression of disease or death from any cause within 63 days of last response assessment.

Secondary Outcome Measures

Objective response rate [Up to approximately 24months]
Defined as the proportion of patients who achieve partial response or complete response according to RECIST 1.1.

16 Years to 70 Years

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Ages 16-70, male and female.
ECOG score of physical condition was 0-1. This can be extended to 2 points for amputees.
Expected survival ≥3 months.
Subjects with distant metastases or locally advanced soft tissue sarcomas determined by the investigator to be unsuitable for surgical treatment (pathologic subtypes include undifferentiated pleomorphic sarcomas, synovial sarcomas, leiomyosarcomas, hemangiosarcomas, clear cell sarcomas, epithelioid sarcomas, fibrosarcomas, and undifferentiated/poorly differentiated liposarcomas).
Subjects with metastatic/surgically unresectable soft tissue sarcoma who received prior systemic treatment or who had a sensitive recurrence (a recurrence more than 6 months after the last chemotherapy) after chemotherapy.
Measurable lesions in compliance with RECIST1.1 criteria.
All acute toxicities resulting from prior antitumor therapy or surgery were alleviated by the first day of the first cycle (C1D1) to level 0-1 (according to NCI-CTCAE 4.03) or to the level specified in the inclusion/exclusion criteria (except for toxicities such as hair loss that the investigator did not consider to pose a safety risk to the subject).
