NEST-1 Trial Summary

This trial is testing a new combination therapy for colorectal cancer patients before surgery. The two drugs given target the immune system and the study will observe any side effects and the efficacy of the treatment.

Who is the study for?
This trial is for adults with early-stage (1-3) colorectal cancer who are planning to have surgery. They must use effective contraception if they can become or get someone pregnant. It's not for those with metastatic cancer, previous immune checkpoint inhibitor treatments, active infections needing treatment, other ongoing clinical trials participation, pregnancy or breastfeeding, on immunosuppressants, or serious heart conditions.Check my eligibility
What is being tested?
The study tests a combination of two investigational drugs: balstilimab and botensilimab—both targeting the immune system—to see their effects on colorectal cancer before surgical tumor removal. Participants will receive these drugs intravenously over an 8-week period prior to surgery.See study design
What are the potential side effects?
Potential side effects include reactions related to the immune system such as inflammation in various organs, infusion-related reactions from the IV administration process itself, fatigue, possible digestive issues due to gut inflammation and increased risk of infections.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Cohort A and B: Pathological overall response (pOR) rate determined by analysis of tissue resected during surgery reported by cohort
Cohort A: Number of participants who experience potentially treatment-related SAEs according to the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 at 90 days following the last treatment with balstilimab or botensilimab
Cohort A: Number of participants who experience treatment-related complications leading to delays of 12 weeks or more in surgery after treatment initiation (Day 0)
+1 more
Secondary outcome measures
All Cohorts: Changes in Minimal Residual Disease assessed using ctDNA pre- and 30 days post-surgical resection

NEST-1 Trial Design

3Treatment groups
Experimental Treatment
Group I: Cohort C:Experimental Treatment2 Interventions
Botensilimab and balstilimab are both monoclonal antibodies that are administered intravenously. Four doses of balstilimab (240 mg IV), will be administered approximately 2 weeks apart. A single dose of botensilimab (75 mg IV) will be administered on the same day as the first dose of balstilimab. Surgical resection will occur 1-6 weeks following the fourth dose of balstilimab. Cohort C only includes patients with dMMR/MSI-High colorectal cancer.
Group II: Cohort B:Experimental Treatment2 Interventions
Botensilimab and balstilimab are both monoclonal antibodies that are administered intravenously. Four doses of balstilimab (240 mg IV), will be administered approximately 2 weeks apart. A single dose of botensilimab (75 mg IV) will be administered on the same day as the first dose of balstilimab. Surgical resection will occur 1-6 weeks following the fourth dose of balstilimab.
Group III: Cohort A: Botensilimab and balstilimab (bot/bal)Experimental Treatment2 Interventions
Botensilimab and balstilimab are both monoclonal antibodies that are administered intravenously. Two doses of balstilimab (240 mg IV), will be administered approximately 2 weeks apart. A single dose of botensilimab (75 mg IV) will be administered on the same day as the first dose of balstilimab. Surgical resection will occur 1-6 weeks following the second dose of balstilimab.

Frequently Asked Questions

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

Has the Food and Drug Administration sanctioned Botensilimab and balstilimab for general use?

"Our team at Power assigned a safety rating of 2 to the combination of Botensilimab and balstilimab (bot/bal), as Phase 2 trials provide evidence regarding safety but not efficacy."

Answered by AI
