Preoperative Nab-paclitaxel, Cisplatin, and Gemcitabine Chemotherapy With or Without Infigratinib Targeted Therapy for the Treatment of Resectable Intrahepatic Cholangiocarcinoma, The OPTIC Trial

This phase II trial assesses the feasibility (including both safety and tolerability) of conducting Next Generation Sequencing and administering targeted therapy (infigratinib) in the preoperative setting for patients with intrahepatic cholangiocarcinoma that can be removed by surgery (resectable). Chemotherapy drugs, such as nab-paclitaxel, cisplatin, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Targeted therapy with infigratinib will bind to FGFR which can help stop tumor cell growth and cause tumor cell death. Giving chemotherapy and/or targeted therapy before surgery may make the tumor smaller for resection and may help prevent the cancer from coming back. If a molecular profiling test shows a genetic change called an FGFR2 fusion, patients receive both chemotherapy and targeted therapy while patients without a FGFR2 fusion just receive chemotherapy. Giving targeted therapy based on molecular profile testing results prior to attempted resection of an intrahepatic cholangiocarcinoma that has a risk for either not being able to be removed or for coming back after it has been removed may help improve treatment outcomes.

PRIMARY OBJECTIVE:

I. To assess the feasibility of a novel treatment strategy that includes conducting next generation sequencing (NGS)-based treatment on a preoperative tissue biopsy and subsequent administration of infigratinib phosphate (infigratinib) to patients with FGFR2 fusions versus neoadjuvant chemotherapy consisting of gemcitabine hydrochloride (gemcitabine), cisplatin, and nab-paclitaxel to all other patients for resectable intrahepatic cholangiocarcinoma.

SECONDARY OBJECTIVES:

I. To evaluate the efficacy of the intervention by assessing the radiological response rate.

II. To assess degree of pathologic response in the surgical specimen. III. To assess response to therapy by measuring circulating tumor deoxyribonucleic acid (CT-DNA).

IV. To determine the R0 resection rate. V. To determine recurrence-free survival (RFS). VI. To determine overall survival (OS).

OUTLINE:

While awaiting NGS molecular profile results, all patients receive nab-paclitaxel intravenously (IV) over 30 minutes, cisplatin IV over 60 minutes, and gemcitabine IV over 30 minutes on days 1 and 8 of one 21-day cycle in the absence of disease progression or unacceptable toxicity.

After obtaining NGS molecular profile results, patients who are FGFR2 fusion/translocation positive are assigned to Arm A, while patients who are FGFR2 fusion/translocation negative are assigned to Arm B.

ARM A: Patients receive infigratinib orally (PO) once daily (QD) on days 1-21 of each cycle. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients whose cancer is stable or improved undergo surgery to remove the tumor within 8 weeks of completing preoperative therapy per standard of care.

ARM B: Patients continue receiving nab-paclitaxel IV over 30 minutes, cisplatin IV over 60 minutes, and gemcitabine IV over 30 minutes on days 1 and 8 of each cycle. Treatment repeats every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Patients whose cancer is stable or improved undergo surgery to remove the tumor within 8 weeks of completing preoperative therapy per standard of care.

After completion of study treatment, patients are followed up within 4 weeks and every 4 months for 3 years.
