About this study
Official title: A Phase I/II Study of the Immune Checkpoint Inhibitor M7824 and the Immunocytokine M9241 in Combination With Stereotactic Body Radiation Therapy (SBRT) in Adults With Advanced Pancreas Cancer
Background:
Fewer than 10 percent of people with pancreas cancer can have surgery. Surgery gives the best outcome. Radiation therapy is usually used to make surgery possible. But it does not work for most people. Adding immunotherapy might help.

Objective:
To find a safe combined dose of Bintrafusp Alfa (M7824), NHS-IL12 (M9241, and radiation and to see if it causes pancreas cancer tumors to shrink.
Eligibility:
People ages 18 and older who have pancreas cancer and cannot have curative surgery
Design:
Participants will be screened under protocol 01-C-0129 with:
Medical history
Physical exam
Heart, urine, and blood tests
Scans. For this, participants will lie in a machine that takes pictures of the body. They may receive a contrast agent by vein.
Possible tumor biopsy
Participants will take the study drugs either alone or with radiation. They will get M7824 by vein every 2 weeks. They will get M9241 injected under the skin every 4 weeks. Participants who get radiation will get it 5 days in a row the first month.
Participants will have visits every 2 weeks. They will repeat screening tests.
If participants tumors shrink, they will have surgery. If their whole tumor is removed, they will stop treatment. They will otherwise continue treatment as long as they can tolerate it and it is helping them.
Participants will have visits 1 week and 1 month after they stop treatment. Then they will be contacted by phone or email for life. If they stop treatment for a reason other than their disease getting worse, they will have scans every 12 weeks.
Read the detailed description
Background:
- At time of diagnosis, fewer than 10% of newly diagnosed pancreatic cancer patients present with resectable disease (patients who can undergo surgery) and patients able to undergo a margin-negative surgical resection (R0) are reported to have the most favorable outcome.
- Locally advanced, non-metastatic pancreas cancer (LAPC) is observed in up to 30% of all pancreas cancer patients at time of diagnosis (including both borderline resectable and non-resectable disease).
- The primary goal of neoadjuvant therapy in LAPC is, among tumor control and extension of survival, the conversion to resectable disease achieving a R0 resection.
- Radiation therapy (RT) is commonly used as neoadjuvant treatment for LAPC.
- However, currently used RT neoadjuvant treatment regimens result in only about 40%-60% of patients with borderline resectable pancreas cancer to undergo surgical resection, in initially unresectable LAPC patient conversion are even lower, with only 7% - 19% able to undergo resection.
- Combining immunotherapy and radiation therapy could synergistically improve anti-cancer activity.
- Bintrafusp alfa (M7824) is a bifunctional fusion protein consisting of an anti-programmed death ligand 1 (PD-L1) antibody functioning as an immune checkpoint inhibitor and the extracellular domain of transforming growth factor beta (TGF-beta) receptor type 2, a TGF-beta trap.
- The NHS-IL12 (M9241) immunocytokine is composed of 2 interleukin-12 (IL-12) heterodimers, each fused to one of the H-chains of the NHS76 antibody, which has affinity for both single- and double-stranded deoxyribonucleic acid (DNA). M9241 targets delivery of IL12, a proinflammatory cytokine that has been shown anti-tumor activity including objective responses in phase I clinical trials, to regions of tumor necrosis where DNA has become exposed, e.g., after radiation therapy.
- We hypothesize that released neo-epitopes upon increased DNA damage induced by radiation therapy together with the local proinflammatory action of M9241 will complement the anti-tumor activity of M7824 in locally advanced pancreas cancer.
Objectives:
- To determine the safety and tolerability and the recommended phase 2 dose (RP2D) of M7824 and M9241 in combination with stereotactic body radiotherapy (SBRT) as neoadjuvant/perioperative treatment in subjects with pancreas cancer.
- To determine a preliminary estimate of efficacy as best overall response (BOR) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 of M7824 and M9241 in combination with SBRT as neoadjuvant/perioperative treatment in subjects with locally advanced pancreas cancer.
Eligibility:
- Histologically or cytologically proven pancreatic adenocarcinoma.
- Patient must be eligible to undergo stereotactic body radiation therapy (SBRT) (Cohorts 2-3).
- Patients must have measurable disease.
- Age greater than or equal to 18 years
Design:
- This is an open label Phase I/II trial. During phase I the safety and tolerability of M7824 and M9241 will be evaluated and recommended Phase II dose (RP2D) of M7824 and M9241 in combination with SBRT will be estimated. During phase II efficacy of the M7824 and M9241 in combination with SBRT will be examined.
- Patients will receive treatment in cycles consisting of 28 days (with exception of additional administer of M7824 alone in Phase IA).
- Treatment will continue until unacceptable toxicity or disease progression.
- If during treatment patient become candidate for curative surgery, treatment will be stopped and can be restarted after surgery in case if surgical exploration does not result in the successful removal of the tumor.

Primary outcome
Recommended Phase 2 Dose (RP2D) of NHS-IL12 (M9241) Given With Bintrafusp Alfa (M7824) in Combination With Stereotactic Body Radiation Therapy (SBRT) as Neoadjuvant / Perioperative Treatment in Participants With Pancreas Cancer
Time frame: First 28 days of treatment
The recommended phase 2 dose (RP2D) is the dose level of M9241 in combination with M7824 at which ≤1 of 6 individuals experienced a dose limiting toxicity (DLT) during the first cycle (28 days) of combinational treatment with M9241 and M7824. A DLT is any Grade ≥ 3 adverse events occurring during the first 28 days of treatment except adverse events unrelated, or unlikely related to study agents and probably or definitely related to other causes.
Number of Participants With ≥Grade 3 Toxicities Possibly, Probably, or Definitely Related to Treatment of Bintrafusp Alfa (M7824) and NHS-IL12 (M9241) in Combination With Stereotactic Body Radiation Therapy (SBRT)
Time frame: Date treatment consent signed to date off study, approximately 4 months and 13 days.
Adverse events were assessed using the Common Terminology Criteria for Adverse Events (CTCAE)v5.0. Grade 3 is severe, Grade 4 is life-threatening, and Grade 5 is death related to adverse events.
Best Overall Response (BOR) According to the Response Evaluation Criteria in Solid Tumors (RECIST) of Bintrafusp Alfa (M7824) & NHS-IL12 (M9241) in Combination With Stereotactic Body Radiation Therapy in Participants With Locally Advanced Pancreas Cancer
Time frame: time measurement criteria are met for complete response or partial response until the first date that recurrent or progressive disease is objectively documented
Best overall response is measured from the time measurement criteria are met for complete response or partial response until the first date that recurrent or progressive disease is objectively documented using the Response Evaluation Criteria in Solid Tumors (RECIST). Complete Response (CR) is disappearance of all target lesions. Partial Response (PR) is at least a 30% decrease in target lesions. In the case of a PR or CR a confirmatory computed tomography or magnetic resonance imaging scan should be done no sooner than 4 weeks. Progressive Disease (PD) is at least a 20% increase in target lesions and/or the appearance of new lesions.
6 secondary outcomes
Overall Survival (OS) in Participants After Completion of Radiation Therapy (RT) in Combination With NHS-IL12 (M9241) and Bintrafusp Alfa (M7824)
Time frame: date of on-study to the date of death from any cause or last follow
Progression-free Survival (PFS) for All Participants
Time frame: Time interval from start to treatment to disease progression, an average of 4 months.
Progression-free Survival (PFS) for Participants Who Did Not Undergo Surgical Resection
Time frame: time interval from start of treatment to documented evidence of disease progression
Fraction of Participants With Locally Advanced, Non-metastatic Pancreas Cancer (LAPC) Who Are Able to Undergo Surgical Resection After Bintrafusp Alfa (M7824) and NHS-IL12 (M9241) in Combination With Stereotactic Body Radiation Therapy (SBRT) Treatment
Time frame: At time of surgical resection

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing M7824, M9241 and SBRT in people with Histologically or Cytologically Confirmed Pancreatic Cancer and Unresectable or Borderline Resectable Pancreatic Cancer, run by National Cancer Institute (NCI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 25 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 18 May 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 May 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Recommended Phase 2 Dose (RP2D) of NHS-IL12 (M9241) Given With Bintrafusp Alfa (M7824) in Combination With Stereotactic Body Radiation Therapy (SBRT) as Neoadjuvant / Perioperative Treatment in Participants With Pancreas Cancer (time frame: First 28 days of treatment). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2022.
