Informations complémentaires
Schéma : Infigratinib is an oral drug which selectively binds to fibroblast growth factor receptor (FGFR) 2 and is being developed to treat participants with FGFR2 mutated cholangiocarcinoma. The purpose of the study is to evaluate the efficacy and safety of the investigational agent oral infigratinib vs standard of care chemotherapy (gemcitabine plus cisplatin) in first-line treatment of participants with unresectable locally advanced or metastatic cholangiocarcinoma with FGFR2 gene fusions/translocations. Subjects will be randomized 2:1 to receive infigratinib or gemcitabine plus cisplatin.

STUDY ARMS:
- Experimental: Infigratinib (BGJ398) 125 mg
Infigratinib (BGJ398) 125 mg orally daily, 3 weeks on, 1 week off.

- Active Comparator: Gemcitabine + Cisplatin
Gemcitabine: 1000 mg/m2 IV D1 and D8 for a 21-day cycle
Cisplatin: 25 mg/m2 IV D1 and D8 for a 21-day cycle
Participants who experience disease progression while receiving gemcitabine + cisplatin will be allowed to cross over and receive infigratinib if certain criteria are met.


PRIMARY OBJECTIVE:
The primary objective is to determinate if treatment with infigratinib improves centrally assessed progression-free survival (PFS) compared to treatment with gemcitabine with cisplatin in subjects with advanced/metastatic or inoperable cholangiocarcinoma with fibroblast growth factor receptor 2 (FGFR2) gene fusions/ translocations.

SECONDARY OBJECTIVES:
• Evaluate the efficacy of treatment with infigratinib versus gemcitabine and cisplatin in terms of overall survival (OS) for subjects with advanced/metastatic or inoperable cholangiocarcinoma with FGFR2 gene fusions/translocation
• Evaluate the efficacy of infigratinib treatment compared to gemcitabine and cisplatin in terms of investigator assessed PFS
• Further evaluate the efficacy in subjects treated with infigratinib versus gemcitabine with cisplatin by ORR best overall response (BOR), duration of response and disease control rate determined centrally and by the investigator
• Characterize the safety and tolerability of single agent infigratinib
•Evaluar la eficacia del tratamiento con infigratinib en comparación con gemcitabina y cisplatino en términos de supervivencia global (SG) en sujetos con colangiocarcinoma avanzado/metastásico o inoperable con fusiones/translocaciones del gen FGFR2.
•Evaluar la eficacia del tratamiento con infigratinib en comparación con gemcitabina y cisplatino en términos de SSP evaluada por el investigador.
•Evaluar adicionalmente la eficacia en sujetos tratados con infigratinib frente a gemcitabina y cisplatino mediante la TRG, mejor respuesta global (MRG), duración de la respuesta y tasa de control de la enfermedad determinadas de forma centralizada y por el investigador.
•Caracterizar la seguridad y la tolerabilidad de infigratinib en monoterapia.

Informations libres de droit
Critères d'inclusion et de non-inclusion
Critères d'inclusion : 1. Have histologically or cytologically confirmed non-resectable, recurrent, or metastatic cholangiocarcinoma. Subjects with gallbladder cancer or ampulla of Vater carcinoma are not eligible.
2. Have written documentation of local or central laboratory determination of FGFR2 gene fusions/translocations. Note: Central confirmation is not required prior to enrollment in study.
3. Have a representative tumor sample available for central FGFR2 fusion/translocation molecular testing. An archival tumor sample and associated pathology report may be submitted. However, if not available, a newly obtained tumor biopsy may be submitted instead.Note: If available FGFR2 fusion/translocation written documentation is from the central laboratory being used in the study, a tumor sample does not need to be submitted for central FGFR2 fusion/translocation molecular testing.
4. Have full recovery from the following permitted prior treatments (as applicable) such that the subject is reasonably expected to tolerate study treatment (gemcitabine/cisplatin or infigratinib) according to the investigator’s assessment:
a. A non-curative operation (ie., R2 resection [with macroscopic residual disease] or palliative bypass surgery only)
b. Curative surgery with evidence of non-resectable disease relapse requiring systemic chemotherapy
c. Adjuvant radiotherapy (with or without radio-sensitizing low-dose chemotherapy) for localized disease provided there has been clear evidence of disease progression before inclusion in this study
d. Adjuvant chemotherapy, provided the treatment was completed > 6 months before trial entry
e. Photodynamic treatment provided there is clear evidence of disease progression at the local site or at a new metastatic site.
5. Are ≥ 18 years of age of either gender.
6. Have an Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1.
7. Have a life expectancy > 3 months.
8. Are able to read and/or understand the details of the study and provide written evidence of informed consent as approved by Institutional Review Board (IRB)/Independent Ethics Committee (IEC).
9. Have recovered from AEs of previous systemic anti-cancer therapies to baseline or Grade 1, except for alopecia.
10. Are able to swallow and retain oral medication.
11. Are willing and able to comply with scheduled visits, treatment plan and laboratory tests.
12. If a woman of childbearing potential (WOCBP), must have a negative pregnancy test within 7 days of the first dose of study drug. A woman is not of childbearing potential if she has undergone surgical sterilization (total hysterectomy, or bilateral tubal ligation or bilateral oophorectomy at least 6 weeks before taking study drug) or if she is postmenopausal and has had no menstrual bleeding of any kind including menstrual period, irregular bleeding, spotting, etc., for at least 12 months, with an appropriate clinical profile, and there is no other cause of amenorrhea (eg., hormonal therapy, prior chemotherapy).

Critères de non-inclusion : 1. Have received treatment with any systemic anti-cancer therapy for unresectable, recurrent, or metastatic cholangiocarcinoma. Prior neoadjuvant or adjuvant therapy is permitted if completed > 6 months prior to first dose of study drug.
2. Have history of a liver transplant.
3. Have received prior or current treatment with a MEK or selective FGFR inhibitor.
4. Have neurological symptoms related to underlying disease requiring increasing doses of corticosteroids. Note: Steroid use for management of central nervous system tumors is allowed but must be at a stable dose for at least 2 weeks preceding study entry.
