Emavusertib with Chemoimmunotherapy for Advanced Biliary Tract Cancer

This study is testing a new combination treatment for advanced or metastatic biliary tract cancer (cancer that has spread). It combines a drug called emavusertib (CA-4948) with standard treatments: gemcitabine, cisplatin, and durvalumab. Researchers believe emavusertib might help these standard treatments work better by affecting how cancer cells survive and how the body's immune system responds. The main goal is to see how safe this combination is and to find the best dose of emavusertib. You might be able to join if you have advanced biliary tract cancer that hasn't been treated yet and is measurable. This study is looking for 48 participants.

Study design
This is an interventional study, meaning participants will receive a specific treatment. It will involve a dose escalation phase to find the best dose, followed by an expansion phase, and plans to enroll 48 participants.
What's involved
You would receive emavusertib in combination with cisplatin, gemcitabine, and durvalumab for up to 8 cycles. After 8 cycles, you would continue with emavusertib and durvalumab for maintenance.
Compensation
Not stated in the trial record.
Follow-up
Your safety will be monitored from consent through 30 days after your last dose of study treatment, which is estimated to be 15 months.

Eligibility criteria

Inclusion

Advanced unresectable or metastatic histologically or cytologically confirmed adenocarcinoma of the biliary tract, including cholangiocarcinoma (intrahepatic or extrahepatic) and gallbladder carcinoma. Patients whose tumor have mixed histology but predominantly (\>50%) adenocarcinoma are allowed.
Measurable defined by RECIST v1.1.
No prior systemic treatment for advanced unresectable or metastatic BTC with the following exceptions:
Neoadjuvant or adjuvant systemic therapy completed \> 6 months from planned C1D1.
Up to two prior cycles of gemcitabine/cisplatin/anti-PD1 with no evidence of disease progression is allowed
At least 18 years of age.
ECOG performance status 0, 1, or 2
Adequate bone marrow and organ function as defined below:
Absolute neutrophil count ≥ 1.5 K/cumm
Platelets ≥ 100 K/cumm
Hemoglobin ≥ 9.0 g/dL
Total bilirubin ≤ 1.5 x IULN or ≤ 3 x IULN in patients with documented Gilbert's syndrome
AST(SGOT)/ALT(SGPT) ≤ 2 x IULN, unless there are liver metastases in which case AST and ALT ≤ 5.0 x IULN
Creatinine clearance ≥ 35 mL/min by Cockcroft-Gault
INR ≤ 1.5 and activated partial thromboplastin time (aPTT) ≤1.5 x IULN
Creatinine phosphokinase (CPK) elevation at screening \< Grade 2 (CPK \< 2.5 x IULN).
Patients on a cholesterol lowering statin must be on a stable dose with no dose changes within 3 weeks prior to study start.
The effects of emavusertib on the developing human fetus are unknown. For this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of the study, and 90 days after completion of the study.
Ability to understand and willingness to sign an IRB approved written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants.

Exclusion

Current use or anticipated need for alternative, holistic, naturopathic, or botanical formulations used for the purpose of cancer treatment. Use of medical marijuana is permitted.
A history of other malignancy with the exception of 1) malignancies for which all treatment was completed at least 2 years before registration and the patient has no evidence of disease; 2) or known indolent malignancies that do not require treatment and will likely not alter the course of treatment of BTC in the opinion of the investigator
