Clinical Trial Summary

The study trial is a open-label, single-arm, multicenter phase II trial investigating the combined treatment of atezolizumab and derazantinib in patients with advanced intrahepatic cholangiocarcinoma with FGFR2 fusions/rearrangements

Description:

The aim of this phase II study is to explore the safety and anti-tumor efficacy of the combination of atezolizumab and derazantinib in patients with advanced intrahepatic cholangiocarcinoma, with ORR as the primary endpoint.

The primary endpoint is the Objective Response Rate (ORR [assessed every 8 weeks (±7 days)]):

Objective response rate (ORR) according to investigator-based RECIST 1.1 assessment, defined as the proportion of allocated subjects with best response of complete or partial response within 9 months after the date of first administration of study treatment.

The secondary endpoints are safety and efficacy and will be evaluated by

• Incidence, treatment relationship, seriousness, and severity of all AEs, SAEs, AESIs according to CTCAE V5.0

• ORR@EOT:

Objective response rate (ORR) according to investigator-based RECIST 1.1 assessment, defined as the proportion of allocated subjects with best response of complete or partial response within study treatment.

• PFSR@6, 8 and 10 months: The proportion of patients known to be alive and without confirmed objective disease progression at 6, 8 and 10 months after first administration of study treatment, respectively.

• PFS: Time from first administration of study treatment until the date of first objective disease progression or death.

• OS: Time from first administration of study treatment until death of a patient due to any cause

Eligibility

Inclusion Criteria:

Patients must meet all of the following criteria to be eligible for the study:

1. Fully informed written consent and locally required authorization (European Union [EU] Data Privacy Directive in the EU) obtained from the patient prior to performing any protocol-related procedures, including screening evaluations.

2. Patients*, age = 18 years at the time of signing the Informed Consent Form.

3. Histologically documented diagnosis of non-resectable iCCA with positively confirmed FGFR2 fusion/rearrangement via NGS-Analysis.

Note: Only CE-IVD marked NGS-tests are applicable which cover FGFR2 fusions and rearrangements.

4. Performance status (PS) = 2 (ECOG scale).

5. At maximum one previous line of systemic anti-cancer therapy, (chemotherapy, hormonal, targeted therapy, experimental therapy) for which treatment was discontinued at least 4 weeks before the first dose of study treatment, or five half-lives of the respective anti-cancer therapy, whichever is the longer period.

Note: For mABs in previous therapy the restriction to five half-lives does not apply.

6. No prior treatment with any FGFR or immune checkpoint inhibitor (including but not limited to antiCTLA-4, antiPD-1, and antiPD-L1 therapeutic antibodies) apart from Durvalumab as PD-L1 inhibitor in first line therapy.

7. Body weight > 30 kg AND BMI = 15.

8. At least one measurable site of disease as defined by RECIST 1.1 criteria.

9. Adequate bone marrow and renal function including the following:

• Hemoglobin = 9.0 g/dL (previous transfusion permitted);

• Absolute neutrophil count (ANC) = 1.500 per µL (1.5×109/L);

• Platelet count = 75,000 per µL (75 × 109/L);

• International normalized ratio (INR) between 0.8 × ULN to 1.0 × ULN OR = 3 × ULN for subjects receving anticoagulant therapy

• Creatinine = 1.5 × ULN OR CLCR = 50 mL/min (as calculated by the Cockcroft-Gault formula);

• serum phosphate = ULN;

• corrected serum calcium = 1.75 mmol/L (= 7.0 mg/dL) AND = 3.1 mmol/L (= 12.5 mg/dL);

• serum sodium = LLN.

10. Adequate hepatic function (with stenting for any obstruction, if required) including the following:

o Total bilirubin = 2 × ULN;

• AST or ALT = 3 × ULN (or = 5 × ULN for subjects with liver metastases);

• Prothrombin time = 60%;

• Albumin = 2.8 g/dL.

11. For patients with active hepatitis B virus (HBV):

• HBV DNA = 500 IU/mL obtained within 28 days prior to initiation of study treatment, AND

• Anti-HBV treatment (per local standard of care; e.g., entecavir) prior to study entry and willingness to continue treatment for the length of the study.

12. For patients with active hepatitis C virus (HCV):

• Patients positive for hepatitis C virus (HCV) antibody are eligible, also if polymerase chain reaction testing is positive for HCV ribonucleic acid (RNA).

• However, anti-viral therapy against HCV is only allowed prior to trial but not during the trial.

13. Negative HIV test.

14. Negative pregnancy test within 72 h prior to dosing.

15. Females of childbearing potential must agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 5 months or for a period of at least 5 half-lives of the respective drug/IMP (whichever is longer) after the last study treatment. A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (has not had = 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal implants, established, proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.

16. With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of 1% per year from screening to 5 months after the last dose of combination therapy or for a period of at least 5 half-lives of the respective drug/IMP after the last dose of combination therapy (whichever is longer). Men must refrain from donating sperm during this same period. Men with a pregnant partner must agree to remain abstinent or to use a condom for the duration of the pregnancy to avoid exposing the embryo.

17. The patient is willing and able to comply with the protocol for the duration of the study, including hospital visits for treatment and scheduled follow-up visits and examinations.

18. Must have a life expectancy of at least 12 weeks. *There are no data that indicate special gender distribution. Therefore, patients will be enrolled in the study gender-independently.

Exclusion Criteria:

Patients who meet any of the following criteria will be excluded from study entry:
