  • Malignancies other than BTC within 5 years prior to study enrollment, with the exception of those with a negligible risk of metastasis or death and treated with expected curative outcome (such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized prostate cancer treated with curative intent, or breast ductal carcinoma in situ treated surgically with curative intent).
  • Prior history of brain metastasis (unless previously treated, asymptomatic and stable for at least 3 months) or organ transplant.
  • Major surgery (excluding placement of vascular access) within 4 weeks of the first dose of study treatment.
  • Active bleeding during the last 4 weeks prior to screening or in the investigator's judgment, the existence of high bleeding tendency lesions such as active gastrointestinal ulcers or prominent esophageal or gastric varices.

  • Significant cardiovascular disease, including:
  • Heart disease classified as New York Heart Association class III or IV.
  • Ongoing uncontrolled hypertension.
  • History of congenital long QT syndrome.
  • Ongoing prolonged QT interval corrected for heart rate using Fridericia's method (QTcF) defined as ≥ 470 msec.
  • History of serious ventricular arrhythmia (ie, ventricular tachycardia or ventricular fibrillation).
  • Subjects with atrial fibrillation, that is well controlled with treatment, can be enrolled. Active heart disease including symptomatic heart failure (NYHA class 3 or 4), unstable angina pectoris, uncontrolled cardiac arrhythmia or interstitial lung disease. Prolonged QTcF interval >480 msec.
  • Ongoing active, uncontrolled infection (must be afebrile for > 48 hours off antibiotics).
  • With the exception of alopecia, any unresolved toxicities from prior therapy ≥Common Terminology Criteria for Adverse Events (CTCAE) Grade 2.
  • Pregnancy or breastfeeding. (Women must not be pregnant or breastfeeding since study drugs may harm the fetus or child. All females of childbearing potential [not surgically sterilized and between menarche and 1 year post menopause] must have a negative screening pregnancy test.)
  • History of human immunodeficiency virus infection.
  • History of autoimmune disease.
  • Ascertained hypersensitivity to gemcitabine, cisplatin, camrelizumab or apatinib, or drugs with similar chemical structures, or its inactive components. If there is suspicion that the subject may have an allergy, the subject should be excluded.
  • Psychiatric illness, other significant medical illness, or social situation which, in the investigator's opinion, would limit compliance or ability to comply with study requirements. Judgment by the investigators that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements.

About this study

Official title: Camrelizumab Combined With Apatinib and Gemcitabine Plus Cisplatin as First-line Therapy for Patients With Inoperable/Metastatic Biliary Tract Cancer (BTC): An Open-label, Single-arm, Single-center, Phase Ib/II Clinical Study

The objective of this study is to investigate the safety and tolerability of camrelizumab combined with apatinib and chemotherapies (gemcitabine and cisplatin) in patients with advanced biliary tract cancer (BTC).

Read the detailed description

The study consists of 2 parts, a dose-escalation part (Phase 1) and an expansion part (Phase 2). Both parts will enroll participants with advanced unresectable biliary tract cancer that had not previously treated with systemic therapy.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Camrelizumab and Apatinib Plus GPDrug

    Also called Apatinib (Apatinib Mesylate Tablets, Jiangsu Hengrui Medicine, China), Camrelizumab (Carelizumab for Injection, Jiangsu Hengrui Medicine, China)

    Patients received apatinib orally at 250 mg once a day irrespective of the patient weight.

    Camrelizumab 200 mg was administered intravenously over 30 minutes every 3 weeks.

    GP chemotherapy: Gemcitabine/Cisplatin (gemcitabine 1000mg/m2 + cisplatin 25mg/m2) will be administered on D1/D8 in every three weeks cycle and up to 8 cycles.

    All patients continued combination treatment until disease progression, unacceptable toxicity, or discontinuation for any reason.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of dose-limiting toxicity

    Dose limiting toxicities will determine the maximum tolerated dose (MTD)/recommended Phase 2 dose (RP2D) of combination therapy with camrelizumab + apatinib and gemcitabine plus cisplatin. Assessed using the NCI CTCAE v5.0

    Measured: up to day 22

  2. Recommended phase 2 dose(RP2D) of apatinib

    To determine a RP2D of apatinib for each population of biliary tract carcinoma subjects.

    Measured: 12 weeks

  3. Objective Response Rate (ORR)

    Defined as percentage of participants achieving assessed complete response (CR) and partial response (PR) by the investigator according to the RECIST 1.1.

    Measured: up to 24 months

Secondary outcomes (4)

  1. Adverse Events (AE)

    overall incidence of adverse events (AE); incidence of grade 3 or higher AE; incidence of severe adverse events (SAE); incidence of AEs leading to discontinuation of drug use; incidence of AEs leading to suspension of drug use.

    Measured: up to 24 months

  2. Disease Control Rate (DCR)

    DCR was defined as the percentage of participants who have a confirmed complete response（CR） or partial response（PR） or stable disease（SD） per RECIST 1.1 as assessed by investigator

    Measured: up to 24 months

  3. Progression-Free Survival (PFS)

    PFS is defined as the time from enrollment to the first documented disease progression or death due to any cause, whichever occurs first. Responses are according to the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by investigator

    Measured: up to 24 months

  4. Overall Survival (OS)

    OS is the time from enrollment to death due to any cause.

    Measured: up to 24 months
