A Study of Botensilimab in Participants With Metastatic Pancreatic Cancer
- Conditions
- Metastatic Pancreatic Ductal Adenocarcinoma
- Interventions
- Registration Number
- NCT05630183
- Lead Sponsor
- Agenus Inc.
- Brief Summary
The goal of this clinical trial is to test if the addition of botensilimab to standard chemotherapy improves the efficacy compared to just chemotherapy alone in participants with metastatic pancreatic cancer. One group of participants will only receive chemotherapy while a second group of participants will receive botensilimab and chemotherapy.
- Detailed Description
This will be a prospective, multicenter, clinical trial of botensilimab in combination with nab-paclitaxel + gemcitabine or nab-paclitaxel + gemcitabine alone. The trial will be conducted in 2 parts. Part 1 will be a safety lead-in to establish the safety and dose of botensilimab for Part 2. Part 2 will be a randomized, open-label assessment of botensilimab (at the dose level determined in Part 1).

- Target Recruitment
- 78
- Histologically confirmed diagnosis of pancreatic ductal adenocarcinoma. Note: fine needle aspirate/cytology of tumor in the presence of a pancreatic mass that confirms ductal adenocarcinoma is acceptable.
- Must have had disease progression on any version of FOLFIRINOX for metastatic disease (including onivyde + oxaliplatin + 5-fluorouracil [5-FU] + leucovorin [NALIRIFOX]). Clarification: Participant with initial diagnosis of locally advanced disease may be eligible if upon retrospective review of initial scans, previously unappreciated metastases are able to be identified; Investigator must provide documentation that participant had metastatic disease at the time the participant received FOLFIRINOX. Notes: Progression on a reduced or maintenance fluoropyrimidine based regimen in the metastatic setting is allowed (for example, leucovorin + 5-FU + oxaliplatin [FOLFOX], leucovorin + 5-FU + irinotecan [FOLFIRI], 5-FU, or capecitabine), provided the participant received at least 1 dose of all of the drugs in a FOLFIRINOX regimen.

- Measurable disease on baseline imaging per RECIST 1.1 criteria.
- A < Grade 2 pre-existing peripheral neuropathy per National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0). Because NCI CTCAE v5.0 grading for peripheral neuropathy does not include guidance for "mild" neuropathy, these cases can be graded per the NCI CTCAE v5.0 grading for general adverse events which includes "mild" under Grade 1.
- Acceptable coagulation status as indicated by an international normalized ratio ≤ 1.5 x institutional ULN, except participants on anticoagulation who can be included at the discretion of the investigator.

-
History of central nervous system (CNS) metastasis or active CNS metastasis.
-
Concurrent malignancy (present during screening) requiring treatment or history of prior malignancy active within 2 years prior to the first dose of study drugs (that is, participants with a history of prior malignancy are eligible if treatment was completed at least 2 years prior to first dose of study drugs and the participant has no evidence of disease).

- Monoclonal antibodies, antibody-drug conjugates, radioimmunoconjugates, or investigational drug, within 4 weeks, or 5 half-lives, whichever is shorter.
- Small molecule targeted therapies/tyrosine kinase inhibitors within 14 days or 5 half-lives (whichever is greater).
- Radiotherapy within 7 days.
-
Previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection within 10 days for mild or asymptomatic infections or 20 days for severe/critical illness prior to first dose of study drugs.
-
Received a vaccine, including SARS-CoV-2 vaccine, < 7 days prior to first dose of study drugs.
-
Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients.
-
Symptomatic interstitial lung disease (ILD), history of ILD, or any lung disease which may interfere with detection and management of new immune-mediated pulmonary toxicity.
-
History of allogeneic organ transplant.
-
Psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the study.
-
Participants with a condition requiring systemic treatment with either corticosteroids (> 10 milligrams [mg] daily prednisone equivalent) within 14 days or another immunosuppressive medication within 30 days prior to the first dose of study drugs. Inhaled or topical steroids, and adrenal replacement steroid doses (≤ 10 mg daily prednisone equivalent), are permitted in the absence of active autoimmune disease.
-
Active autoimmune disease or history of autoimmune disease that required systemic treatment within 2 years prior to first dose of study drugs (that is, with use of disease-modifying agents or immunosuppressive drugs).

- Primary Outcome Measures
Name Time Method Progression-free Survival as Assessed by Independent Central Review Committee (IRC) Up to 2 years Progression-free survival will be defined as the time from the date of randomization to the date of the first objectively documented tumor progression, assessed by IRC per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), or death, whichever occurs first.
- Secondary Outcome Measures
Name Time Method Number Of Participants With Treatment-emergent Adverse Events First study dose through up 1 year Rates Of Normalization Of Carbohydrate Antigen 19-9 Up to 2 years Carbohydrate antigen 19-9 normalization will be defined as a value of carbohydrate antigen 19-9 down to normal limits (from at least \> 2 x ULN). Cancer antigen 125 or carcinoembryonic antigen will be evaluated for non-expressors of carbohydrate antigen 19-9.
Overall Survival Up to 2 years Overall survival will be defined as the time from the date of randomization to the date of death due to any cause.
Progression-free Survival as Assessed by Investigators Up to 2 years Progression-free survival will be defined as the time from the date of randomization to the date of the first objectively documented tumor progression, assessed by investigators per RECIST 1.1, or death, whichever occurs first.
Overall Response Rate Up to 2 years Overall response rate will be defined as the proportion of participants whose best overall response is complete response or partial response assessed by IRC and investigators per RECIST v1.1.
Complete Response Up to 2 years Complete response will be assessed by IRC per RECIST 1.1 criteria and carbohydrate antigen 19-9 down to normal limits (from at least \> 2 x upper limit of normal \[ULN\]). Cancer antigen 125 or carcinoembryonic antigen will be evaluated for non-expressors of carbohydrate antigen 19-9.
Duration Of Response Up to 2 years Duration of response will be defined as the time from the first determination of an objective response assessed by IRC and investigators per RECIST v1.1, until the first documentation of progression or death, whichever occurs first.
Change From Baseline In Carbohydrate Antigen 19-9 Baseline, 2 years Change in carbohydrate antigen 19-9 will be evaluated until progressive disease, death, date of last tumor assessment, or start of new anti-cancer therapy.
