Camrelizumab in Combination With PLD and Losartan in Patients With TNBC Who Have Received ≦ 1 Line of Chemotherapy

Camrelizumab Combined With Liposomal Doxorubicin and Losartan in the Treatment With Advanced or Locally Advanced Triple-negative Breast Cancer Who Have Received no More Than 1 Prior Line of Chemotherapy

This is a phase II, single-arm, multi-center, prospective clinical study of camrelizumab in combination with liposomal doxorubicin and losartan in patients with advanced or locally advanced triple-negative breast cancer who had received no more than 1 prior line of chemotherapy. Our aim was to explore the efficacy and safety of it.

Study Overview

• Status: Not yet recruiting
• Conditions: Breast Cancer
• Intervention / Treatment: Drug: Camrelizumab; Drug: Liposomal Doxorubicin; Drug: Losartan

Detailed Description

This a phase II, open-labeled, multi-centered, single-arm, investigator-initiated clinical trial to assess the efficacy and safety of camrelizumab combination with liposomal doxorubicin and losartan in female patients age of 18 to 70 with advanced or locally advanced TNBC, and previously treated with no more than one line of chemotherapy in the advanced setting. The number of patients to be included is 52 patients (Simons two stage design). All enrolled patients will be treated with camrelizumab 200mg (iv. 3mg/kg for patient whose weight is below 50kg) on day 1 of each 21-day cycle, and liposomal doxorubicin (40 mg, Q3W for 6 weeks) plus oral losartan (50 mg loading dose followed by 100 mg QD, Q3W, until discontinuation of liposomal doxorubicin).The primary objective is to assess the overall response rate (ORR).

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Camrelizumab, Liposomal doxorubicin and Losartan; Participants receive intravenous camrelizumab (200 mg, Q3W) and liposomal doxorubicin (40 mg, Q3W for 6 weeks) plus oral losartan (50 mg loading dose followed by 100 mg QD, Q3W, until discontinuation of liposomal doxorubicin).

Drug: Camrelizumab; Camrelizumab 200mg (3mg/kg for patient whose weight is below 50kg) will be administered as an intravenous infusion over 30 minutes every three weeks until unacceptable toxic effects or disease progression or other termination criteria appeared.; Drug: Liposomal Doxorubicin; Liposomal Doxorubicin 40 mg/m2 on D1 every 3 weeks; 6 cycles are planned to be completed or discontinued due to intolerable toxicity or progression.; Drug: Losartan; Losartan will be orally administered at 50 mg for three days and increased to 100 mg if tolerated until the whole course of chemotherapy; if not tolerated, it will be maintained at 50 mg until the whole course of chemotherapy

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate (ORR)	ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1	Estimated 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical Benefit rate (CBR)	Ratio of CR,PR and SD greater than or equal to 24 weeks in all subjects	Estimated 12 months
Progression-Free Survival (PFS)	PFS was defined as the time from randomization to first documented disease progression (PD) using Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) or death from any cause, whichever occurred first. For target lesions, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum of the longest diameter recorded since treatment started or the appearance of 1 or more new lesions. For non-target lesions, PD was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions.	Estimated 12 months
Overall Survival (OS)	Overall Survival (OS), defined as the time from the date of randomization to the date of death, regardless of the cause of death. Participants who were alive at the time of the analysis were censored at the date of the last follow-up assessment. Participants without follow-up assessment were censored at the day of last study medication and participants with no post-baseline information were censored at the date of randomization.	Estimated 24 months
Duration of Response (DoR)	DoR is defined as date of initial confirmed PR/CR until date of progressive disease or death from any cause. PR or CR or SD is according to RECIST version 1.1.	Estimated 12 months
Adverse events (AEs)	AEs were graded according to the National Cancer Institute's Common Toxicity Criteria for Adverse Events (CTCAE) version 4.0.3. In general, AEs are graded according to the following: Grade 1 Mild AE Grade 2 Moderate AE Grade 3 Severe AE Grade 4 Life-threatening or disabling AE Grade 5 Death related to AE. The type, grade and frequency of AEs will be reported.	Estimated 12 months
