Brief Summary

To learn about the effects of the drugs regorafenib and lorigerlimab on circulating tumor DNA (ctDNA) in patients with CRC and who have radiographic occult minimal residual disease (MRD) after completing standard-of-care therapy

Detailed Description

Primary Objectives

• To determine the 6-month circulating tumor (ctDNA) clearance rate following 6 months of therapy with RELO regimen in patients with colorectal cancer (CRC) who present with radiographic occult molecular residual disease (MRD) after completing definitive standard-of-care (SOC) therapy.

Secondary Objectives

• To determine the 3-month ctDNA clearance rate following RELO treatment.
• To determine disease-free survival (DFS) following 6 months of RELO treatment.
• To determine overall survival (OS) following 6 months of RELO treatment.
• To determine the safety and tolerability of RELO.

Eligibility Criteria

Exclusion Criteria

• Able to understand and is willing to sign a written informed consent document.
• The effects of RELO on the developing human fetus are unknown. For this reason and because regorafenib appears to be teratogenic in animal models, women of child-bearing potential (refer to MDA Policy CLN 1114) must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry, for the duration of study participation and for at least 4 months after the last dose. This includes all female participants, between the onset of menses (as early as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following:

O Postmenopausal (no menses in greater than or equal to 12 consecutives months).

• History of hysterectomy or bilateral salpingo-oophorectomy.
• Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal
• range, who have received Whole Pelvic Radiation Therapy).
• History of bilateral tubal ligation or another surgical sterilization procedure.) Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice, however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should 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 study participation, and 4 months after completion of administration

• Concurrent treatment with drug with which the interactions are considered clinically significant by investigator (as outlined in section 0). Major surgical procedure or significant traumatic injury within 21 days before start of study medication. Note: If participants received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy
• Grade 2 or higher peripheral neuropathy per CTCAE v5.0.
• Systemic therapy with immunosuppressive agents within 7 days or use of any investigational drug within 28 days before the start of trial treatment except for participants who may be receiving low dose prednisone (specifically receiving ≤10 mg prednisone or equivalent within 7 days of treatment initiation).
• Prior exposure to any immune checkpoint blockade agent or any other immunomodulatory agent used for antineoplastic therapy for mCRC.
• Previous malignant disease (other than the target malignancy to be investigated in this trial) within 3 years prior to study treatment initiation.
• Receipt of any organ transplantation, including allogeneic stem cell transplantation (exception: transplants that do not require immunosuppression, such as hair transplant).
• Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent. The study will allow replacement therapy with thyroxine, insulin or physiologic corticosteroid replacement therapy for autoimmune conditions that are well-controlled.
• Known severe hypersensitivity reactions to monoclonal antibodies (Grade ≥ 3 NCICTCAE v5.0), any history of anaphylaxis, or recent (within 5 months) history of uncontrolled asthma.
• Clinically significant cardiovascular/cerebrovascular disease as follows: cerebral vascular accident/stroke (<6 months prior to enrollment), myocardial infarction (<6 months prior to enrollment), unstable angina, congestive heart failure (New York Heart Association Classification Class >II), myocarditis, or serious cardiac arrhythmia.
• Clinically relevant diseases (for example, inflammatory bowel disease) and / or uncontrolled medical conditions, which, in the opinion of the Investigator, might impair the subject's tolerance or ability to participate in the trial.
• Failure to recover from any other toxicity (other than immune-related toxicity) related to previous anticancer treatment to ≤ Grade 2 per CTCAE v5.0.
• Receipt of a live-virus vaccine within 30 days prior to first dose of study drug (seasonal flu vaccines that do not contain live virus are permitted). Patient should refrain to receive live-virus vaccines for 120 days following the last dose of lorigerlimab.
• Evidence of any serious bacterial, viral (active HIV, HCV or HBV), parasitic, or systemic fungal infections within the 30 days prior to the first dose of study drug.
• Subject is pregnant or breast feeding or planning to become pregnant while enrolled in the study, up to the final EOT visit.
• History of (non-infectious) pneumonitis that required steroids, ongoing pneumonitis, or history of interstitial lung disease.
• History of GI perforation or GI bleeding within 4 weeks, significant diverticulitis or flare within 4 weeks, and acute pancreatitis within 4 weeks.
• Grade > 3 (per CTCAE v5.0) proteinuria (> 3.5 g/24 hours)
• Grade > 3 (per CTCAE v5.0) hypertension (systolic blood pressure > 160 or diastolic blood pressure > 100).
• Evidence or history of bleeding diathesis or coagulopathy within 6 months of start of treatment. Subjects with clinically significant thrombotic, embolic, venous, orarterial events, deep vein thrombosis or pulmonary embolism within 6 months of start of treatment. Participants with incidental findings that have started anticoagulation and are stable are allowed.
• Ongoing infection > Grade 2 NCI-CTCAE v5.0.
• Symptomatic metastatic brain or meningeal tumors.
• Presence of a non-healing wound, non-healing ulcer, or bone fracture.
• Major surgical procedure or significant traumatic injury within 28 days before start of study medication
• Renal failure requiring hemodialysis or peritoneal dialysis.

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
