Study Summary

This trial is investigating whether combining atezolizumab with varlilumab, with or without cobimetinib, is effective in treating biliary tract cancer that cannot be removed by surgery.

Who is the study for?
This trial is for adults with advanced biliary tract cancer that can't be surgically removed, who've had at least one but no more than two prior treatments. They must have a life expectancy over 3 months, good physical function, acceptable blood counts and organ function, agree to use contraception, and be willing to undergo biopsies. Those with certain viral infections must have undetectable viral loads.Check my eligibility
What is being tested?
The study tests combining two immune therapies (Atezolizumab and Varlilumab) with or without Cobimetinib in patients whose biliary tract cancer cannot be operated on. It explores whether this combination helps the immune system fight cancer better than just Atezolizumab and Varlilumab alone.See study design
What are the potential side effects?
Possible side effects include reactions related to the immune system attacking normal organs (like inflammation), infusion-related reactions from receiving drugs through a vein, fatigue, digestive issues such as nausea or diarrhea, liver enzyme changes indicating liver stress or damage, skin rash or itching.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Arm B (atezolizumab, varlilumab)Experimental Treatment6 Interventions
Patients receive atezolizumab IV over 30-60 minutes on days 1 and 15 of each cycle and varlilumab IV over 90 minutes on days 1 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo a CT or MRI at baseline, every 8 weeks while on treatment, and at end of treatment or progression. Patients also undergo a tumor biopsy at baseline and on day 21 of cycle 1. Patients also undergo blood sample collection on study.
Group II: Arm A (cobimetinib, atezolizumab, varlilumab)Experimental Treatment7 Interventions
Patients receive cobimetinib PO QD on days 1-21 of each cycle, atezolizumab IV over 30-60 minutes on days 1 and 15 of each cycle, and varlilumab IV over 90 minutes on days 1 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo a CT or MRI at baseline, every 8 weeks while on treatment, and at end of treatment or progression. Patients also undergo a tumor biopsy at baseline and on day 21 of cycle 1. Patients also undergo blood sample collection on study.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

In what treatments is Cobimetinib typically utilized?

"In addition to small cell lung cancer (SCLC), Cobimetinib can also be deployed for more advanced stages of melanoma, as well as other types of malignant neoplasms."

Answered by AI

Has a study of this kind ever been conducted before?

"Since 2008, Cobimetinib has been the subject of ongoing research. Hoffmann-La Roche sponsored the initial trial in 2008 and following successful results, it was approved at Phase 2. Currently there are 379 active trials taking place across 1651 cities and 74 countries worldwide."

Answered by AI

What is the upper limit of participants undertaking this clinical study?

"This study necessitates 64 appropriate participants to fulfil its requirements. Patients have the ability to join from Wake Forest University Health Sciences in Winston-Salem, North carolina or Laura and Isaac Perlmutter Cancer Center at NYU Langone in New york, Illinois."

Answered by AI

What safety protocols have been established for Cobimetinib use?

"Cobimetinib's safety score was rated as a 2, due to Phase 2 data indicating some level of security but no efficacy evidence."

Answered by AI

Are there any other research studies that are using Cobimetinib as a therapeutic intervention?

"Cobimetinib was initially studied in 2008 by the SCRI Tennessee Oncology Chattanooga. After 230 completed trials, there are now 379 clinical studies actively recruiting patients across numerous locations with a primary center being Winston-Salem, North carolina."

Answered by AI

Is there still room for participants in this experiment?

"Indeed, the information about this trial hosted on clinicaltrials.gov is accurate. This study was first posted in September 2021 and its most recent update occurred in November 2022. Currently, 64 individuals are required to participate from 30 different medical facilities."

Answered by AI

Are there several sites hosting this research project in the United States?

"This trial is being conducted across 30 medical centres, including those in Winston-Salem, New york City and Chicago. If you're participating in the study it's wise to select a clinic close to your home location so as to minimize transportation needs."
