About this trial
This phase II trial tests how well giving gemcitabine, cisplatin and durvalumab alternating with pemigatinib for the treatment of biliary tract cancer with FGFR2 alterations that cannot be removed by surgery (unresectable), that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill cancer cells. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pemigatinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal FGFR protein that signals cancer cells to multiply. This may help keep cancer cells from growing and may kill them. Giving gemcitabine, cisplatin and durvalumab alternating with pemigatinib may work well for the treatment of unresectable, locally advanced or metastatic biliary tract cancer with FGFR2 alterations.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adults 18 years of age or older with histologically or cytologically confirmed unresectable locally advanced or metastatic carcinoma of the biliary tract, including intrahepatic and extrahepatic cholangiocarcinoma, gallbladder, and ampulla of Vater, at the time of diagnosis
Patients must have tumors classified as having FGFR2 gene fusion/rearrangements or other gain-of function alterations involved in FGFR as detected by any analytically validated, Clinical Laboratory Improvement Act (CLIA)-certified molecular testing, including commercial tests (Foundation Medicine, Caris, Tempus, Guardant360, and others) or other platforms of next generation sequencing. Gene rearrangements are structural variants that can include inversions, translocations, duplications, and truncations. In addition, all patients will have tumor specimens sent and stored centrally
Patients are permitted to have received one 21-day or 28-day cycle of either gemcitabine/cisplatin or gemcitabine/cisplatin with immunotherapy (either durvalumab or pembrolizumab) prior to inclusion in trial, and this will count as the first cycle in the schematic
One or more measurable lesions per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v 1.1)
Disqualifiers
Received any definitive radiotherapy, targeted therapy, immunotherapy, or any investigational therapies within 13 days of the first study drug administration. Patients are permitted to have received one 21- or 28-day cycle of either gem/cis or gemcitabine/cisplatin/durvalumab prior to inclusion in trial, and this will count as the first cycle in the schematic. Localized palliative radiation therapy (should not include radiation to target lesions) and ongoing bisphosphonates and denosumab, are permitted
Patients who have not recovered from reversible toxicity of prior anti-tumor therapy (except toxicities which are not clinically significant such as alopecia, grade 0-2 neuropathy)
Patients who received prior FGFR-targeted therapy
Within 2 weeks before the first dose of study drug, the subject's calcium and phosphate level continuing to exceed the ULN despite medical treatment

Trial outcomes
Primary outcomes
Overall survival (OS)
Defined as the date of start of treatment to the date of death due to any cause. Will be analyzed using the Kaplan Meier method. Survival rate at 12 months and median OS will be estimated along with 95% confidence intervals from the Kaplan Meier distribution.
Secondary outcomes
Overall response rate (ORR)
Defined as complete response (CR) + partial response (PR). Assessed by investigator as per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. The estimated ORR will be presented along with the corresponding 95% confidence interval for each cohort, based on a binomial distribution.
Disease control rate
Defined as CR + PR + stable disease. Assessed by investigator as per RECIST v 1.1.
Duration of response
Duration of therapy (DOT)
The median DOT will be presented along with the corresponding 95% confidence interval for each cohort, based on a binomial distribution.
