Who can take part
You may be able to join if
- Signed informed consent form (ICF).
- Appropriate hematological, hepatic and renal function: (a) Absolute number of neutrophils ≥ 1.5 x 10^9/L; (b) Platelets ≥ 100 x 10^9/L; (c) Hemoglobin ≥ 9 g/dL (5.58 mmol/L); (d) Total bilirubin ≤ 1.5 times the upper limit of normal (ULN); (e) AST (SGOT) and ALT (SGPT) ≤ 2.5 x ULN; AP ≤ 5 x ULN.
- Serum creatinine ≤ 1.5 x ULN or creatinine clearance (measured by 24h urine) ≥ 40 mL/min (i.e., if the serum creatinine level is > 1.5 x ULN, then a 24-h urine test must be performed to check the creatinine clearance to be determined).
- Adequate coagulability, as determined by the International Normalized Ratio (INR) ≤ 1.5 and partial thromboplastin time (PTT) ≤ 5 s above the ULN (unless anti-coagulation therapy has been given). Patients receiving warfarin / Phenoprocoumon must be switched to low molecular weight heparin before starting any study-specific procedures.
- Patients infected with human immunodeficiency virus (HIV) are eligible if they meet all the following criteria: (a) CD4 count is ≥350 cells/uL, viral load is undetectable, and not taking prohibited cytochrome (CYP)-interacting medications; (b) Probable long-term survival with HIV if cancer were not present; (c) Stable on a highly active antiretroviral therapy (HAART) regimen for ≥4 weeks and willing to adhere to their HAART regimen with minimal overlapping toxicity and drug-drug interactions with the experimental agents in this study; (d) HIV is not multi-drug resistant; (e) Taking medication and/or receiving antiretroviral therapy that does not interact or have overlapping toxicities with the study medication
- Subject is willing and able to comply with the protocol (including contraceptive measures) for the duration of the study including undergoing treatment, and scheduled visits and examinations including follow up.
You likely can't join if
- Presence of tumors other than biliary tract cancer or a secondary tumor other than squamous or basal cell carcinomas of the skin or in situ carcinomas of the cervix which have been effectively treated. The Sponsor decides to include patients who have received curative treatment and have been disease-free for at least 3 years.
- Current evidence of clinically significant corneal (including but not limited to bullous/band keratopathy, corneal abrasion, inflammation/ulceration, and keratoconjunctivitis) or retinal disorder (including but not limited to central serous retinopathy, macular/retinal degeneration, diabetic retinopathy, retinal detachment) as confirmed by ophthalmologic examination.
- History of calcium and phosphate hemostasis disorder or systemic mineral imbalance with ectopic calcification of soft tissues (exception: commonly observed calcifications in soft tissues, such as the skin, kidney, tendons or vessels due to injury, disease, and aging, in the absence of systemic mineral imbalance).
- History of hypovitaminosis D requiring supraphysiologic doses (eg, 50,000 UI/weekly) to replenish the deficiency. NOTE: Participants receiving vitamin D supplements are eligible.
- Use of any potent CYP3A4 inhibitors or inducers or moderate CYP3A4 inducers within 14 days or 5 half-lives (whichever is longer) before the first dose of study treatment. NOTE: Moderate CYP3A4 inhibitors are not prohibited (refer to section 24.3 Appendix 3 for a list of CYP3A4 inhibitors and inducers).
- Presence of an active, uncontrollable infection.

- For patients with active hepatitis C virus (HCV): Patients positive for HCV antibody are eligible, also if polymerase chain reaction testing is positive for HCV RNA; however, anti-viral therapy against HCV is only allowed prior to trial but not during the trial.
