Derazantinib in Subjects With FGFR2 Gene Fusion-, Mutation- or Amplification- Positive Inoperable or Advanced Intrahepatic Cholangiocarcinoma

• Status: Recruiting
• Trial end date: 2022-06-30
• Target enrollment: 0
• Participant gender: All

Summary

This pivotal, open-label, single-arm study will evaluate the anti-cancer activity of derazantinib by Objective Response Rate (ORR) by central radiology review as per RECIST v1.1 in subjects with inoperable or advanced intrahepatic cholangiocarcinoma (iCCA) whose tumors harbor FGFR2 gene fusions (by FISH performed by the central laboratory) or FGFR2 gene mutations or amplifications (based on NGS testing performed or commissioned by the respective study center) and who received at least one prior regimen of systemic therapy. Subjects will be dosed orally once per day at 300 mg of derazantinib capsules.

• Phase: Phase 2

Criteria

Inclusion Criteria:

1. Signed written informed consent granted prior to initiation of any study-specific procedures

2. 18 years of age or older

3. Histologically or cytologically confirmed locally advanced, inoperable (where surgery is not indicated due to disease extension, co-morbidities, or other technical reasons), or metastatic iCCA or mixed histology tumors (combined hepatocellular-cholangiocarcinoma [cHCC-CCA])

4. Substudy 1: FGFR2 fusion status based on the following assessments:

a) If central laboratory designated by Sponsor: Positive FISH test; and/or b) If non-central laboratory: i) Positive FISH or NGS test: patients may be enrolled and may start dosing, but central confirmation is required* ii) Negative FISH or NGS test: tissue may be submitted to the central laboratory designated by the Sponsor, and patients may only be enrolled if the central test is positive

*Using standard protocols and approved by local IRB/EC, by CLIA or other similar agency.

Substudy 2: FGFR2 mutation/amplification status based on local NGS testing performed or commissioned by the respective study site.

5. Received at least one regimen of prior systemic therapy and then experienced documented radiographic progression

6. Measurable disease by RECIST version 1.1 criteria

7. ECOG performance status ≤ 1

8. Adequate organ functions as indicated by the following laboratory values (based on screening visit values from the central laboratory).

• Hematological

• Hemoglobin (Hgb) ≥ 9.0 g/dL

• Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L

• Platelet count ≥ 75 x 109/L

• International normalized ratio (INR) 0.8 to upper limit of normal (ULN) or ≤ 3 for subjects receiving anticoagulant therapy such as Coumadin or heparin

• Hepatic

• Total bilirubin ≤ 2 x ULN

• AST and ALT ≤ 3 ULN (≤ 5 x ULN for subjects with liver metastases)

• Albumin ≥ 2.8 g/dL

• Renal

• Serum creatinine ≤ 1.5 x ULN

• Creatinine clearance of ≥ 30 mL/min as estimated by the Cockcroft-Gault equation

9. Female and male patients of child-producing potential must agree to avoid becoming pregnant or impregnating a partner, respectively, use double-barrier contraceptive measures, oral contraception, or avoidance of intercourse, during the study*, and until at least 120 for 90 days after the last dose of derazantinib.

*From the day of first study medication, or for oral contraception from 14 days before first study medication.

Male patients are considered not to be of child-producing potential if they have azoospermia (whether due to vasectomy or an underlying medical condition). Female patients are considered not to be of child-producing potential if they are:

• postmenopausal* , or

• have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy or bilateral tubal ligation/occlusion, at least 6 weeks prior to screening, or

• have a congenital or acquired condition that prevents childbearing.

Male or female patients of child-producing potential must agree to comply with one of the following until at least 120 days after the last dose of derazantinib:

1. Abstinence from heterosexual activity**

2. Using (or having their partner use) an acceptable method of contraception during heterosexual activity. Acceptable methods of contraception are***:

• any ONE of:

• an intrauterine device (IUD)

• vasectomy of a female patient's male partner

• a contraceptive rod implanted into the skin.

• any TWO in combination of:

• diaphragm with spermicide (cannot be used in conjunction with cervical cap/spermicide)

• cervical cap with spermicide (nulliparous women only)

• contraceptive sponge (nulliparous women only)

• male condom or female condom (cannot be used together)

• hormonal contraceptive (oral contraceptive pill [estrogen/progestin pill or progestin-only pill], contraceptive skin patch, vaginal contraceptive ring, or subcutaneous contraceptive injection)

*Postmenopausal is defined as at least 12 months with no menses without an alternative medical cause; in women < 45 years of age a high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post -menopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, a single FSH measurement is not sufficient.

• Abstinence (relative to heterosexual activity) can be used as the sole method of contraception if it is consistently employed as the subject's preferred and usual lifestyle and if considered acceptable by local regulatory agencies and ERCs/IRBs. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, post-ovulation methods, etc.) and withdrawal are not acceptable methods of contraception.

• If a contraceptive method listed above is restricted by local regulations/guidelines, then it does not qualify as an acceptable method of contraception for subjects participating at sites in this country/region.

Exclusion Criteria:

1. Receipt of treatment before the first dose of study drug (Cycle 1 Day 1) within an interval shorter than the following, as applicable:

• One chemotherapy or biological (e.g., antibody) cycle interval

• Two weeks, for any investigational medicinal product with an unknown half-life

• Four weeks of curative radiotherapy

• Seven days of palliative radiotherapy

• 28 days of radiotherapy
