Brief Summary:
This is a single-arm, multi-centre, phase II study in biliary tract cancer (BTC) patients. The main objective is to detect an increase in progression-free survival rate at 6 months (according to RECIST version 1.1) from 60% in patients with BTC treated with standard chemotherapy (CT) approach to 75% when treated with CT combined with pembrolizumab.

Condition or disease Intervention/treatment Phase
Biliary Tract Cancer Metastatic Cancer Advanced Cancer Gallbladder Cancer Drug: Pembrolizumab Drug: Cisplatin Drug: Gemcitabine Phase 2

Detailed Description:

Primary endpoint: PFS rate at 6 months according to RECIST 1.1.

Secondary endpoints:

  • Best overall response rate (according to RECIST 1.1 and iRECIST)
  • Response duration and stable disease duration (according to RECIST 1.1 and iRECIST)
  • PFS rate at 6 months according to iRECIST
  • PFS according to RECIST 1.1 and iRECIST
  • Overall survival (OS)
  • Toxicity of treatment (Common Toxicity Criteria CTCAE 5.0)
  • Safety analysis: A safety analysis will be done when at least 10 patients have completed at least one cycle of the three- drug combination.

Events of clinical interest for this safety analysis are the following:

  • At least Grade 2 or higher CTCAE 5.0 signs of acute renal failure
  • Grade 3 or 4 liver dysfunction defined as elevation of liver transaminases (AST and ALT) and alkaline phosphatase, increased bilirubin
  • Grade 3 or 4 gastrointestinal disorders specifically colitis, diarrhea and stomatitis
  • Grade 3 or 4 dyspnea, dry cough and pneumonia
  • Grade 3 or 4 sepsis
  • Grade 3 or 4 skin toxicity If 4 out of these 10 patients experience any of the above, this will trigger an IDMC review. This cut-off is based on: 1) previous ABC-02 study where 57% of patients experienced a grade 3 or 4 toxicity at 12 weeks of treatment; and 2) KEYNOTE 028 where 17% of patients experienced grade 3 or 4 toxicity The primary analysis of efficacy endpoints will be performed in the protocol population.
  • PFS rate at 6 months will be estimated using Kaplan Meier estimate at the time point of interest. The lower bound of the one-sided 90% confidence interval (CI) will be calculated by Greenwood's estimation of the standard deviation. If the lower bound of the one-sided 90% CI is above 60%, it will be concluded that the new treatment is effective enough to warrant further evaluation in a phase III trial. Assuming exponential distributions for both PFS and for the risk of drop-out, power with a total sample size of 50 patients when the primary test is performed using Kaplan Meier analyses will be around 82% for a drop-out rate of 5% at 6 months and still above 80% for a drop-out rate of 10% at 6 months. The one-sided type I error will be respectively 9.33% and 9.02%.
  • PFS rate at 6 months according to iRECIST will be estimated using Kaplan Meier estimate and the one-sided 90% confidence interval (CI) will be calculated by Greenwood's estimation of the standard deviation.
  • BOR rate according to RECIST 1.1 and iBOR rate according to iRECIST will be displayed (point estimate) with their exact two-sided 95% confidence intervals. Response duration and stable disease duration according to RECIST 1.1 and iRECIST will be graphically displayed using swimmer plots and bar charts.
  • Progression free survival according to RECIST 1.1 and iRECIST and overall survival curves will be estimated using the Kaplan-Meier technique. The safety analyses will be performed in the Safety population. The worst toxicity grade per patient over the treatment period according to the CTCAE criteria version 5.0 will be displayed.

Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, shingles, yellow fever, seasonal flu, H1N1 flu, rabies, BCG and typhoid vaccine.
  • Prior treatment with any anti-CTLA4 monoclonal antibody or anti-PD-1, or PD-L1 or PD-L2 agent. Examples of PD-1 inhibitors (include, but are not limited to): pembrolizumab (Merck); Nivolumab (also known as BMS-936558, MDX-1106, ONO-4538) (Bristol-Myers Squibb); Pidilizumab (CT-11) (Cure-Tech/Teva); and AMP-224 (Amplimmune).

  • Prior systemic chemotherapy for locally advanced or metastatic disease.
  • Prior adjuvant chemotherapy is allowed if the last treatment was completed at least 6 months before trial entry and neither gemcitabine nor cisplatin were given. Also the following treatment modalities are allowed within the rules described (provided there has been a full recovery):
  • Surgery - patients may have undergone a non-curative operation (i.e. R2 resection [with macroscopic residual disease] or palliative bypass surgery only). Patients who have previously undergone curative surgery, must have evidence of non-resectable disease relapse requiring systemic chemotherapy prior to study entry.
  • Radiotherapy - patients may have received prior radiotherapy (with or without radiosensitising low-dose chemotherapy) for localised disease. However, there must be clear evidence of disease progression prior to inclusion in this study.
  • Photodynamic therapy (PDT) for localized disease only with no evidence of metastatic disease - patients may have received prior PDT, provided the patient has fully recovered and at least 28 days have elapsed since the PDT and there is clear evidence of disease progression at the local site or disease or at a new metastatic site.
  • PDT for localised disease to relieve biliary obstruction in the presence of metastatic disease - patients may have received prior PDT provided the patient has fully recovered and at least 28 days have elapsed since the PDT. Patients may enter trial provided the non-PDT treated lesion(s) only are followed for response assessment.
  • Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before enrollment in the trial.
