Brief Summary
This phase II trial studies how well retreatment with panitumumab works compared to standard of care regorafenib or trifluridine and tipiracil hydrochloride (TAS-102) in treating patients with colorectal cancer that is negative for RAS wild-type colorectal cancer has spread to other places in the body (metastatic), and/or cannot be removed by surgery (unresectable), and is negative for resistance mutations in blood. Treatment with panitumumab may interfere with the ability of tumor cells to grow and spread. Some tumors need growth factors to keep growing. Growth factor antagonists, such as regorafenib, may interfere with the growth factor and stop the tumor from growing. Drugs used in chemotherapy, such as TAS-102, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving panitumumab may work better in treating patients with colorectal cancer than with the usual treatment of regorafenib or TAS-102.

Outcome Measures
Primary Outcomes (1)
Overall Survival (OS)
OS is defined as the Time from randomization to death from any cause. The distribution of overall survival will be estimated using the method of Kaplan-Meier. Overall survival will be compared between the 2 treatment arms using the un-stratified log-rank test will be used.

Study Arms (2)
Arm A (panitumumab)
EXPERIMENTALPatients receive panitumumab IV over 30-90 minutes on days 1 and 15. Treatment repeats every 28 days for a maximum of 24 cycles in the absence of disease progression or unacceptable toxicity.
Arm B (regorafenib, trifluridine and tipiracil hydrochloride)
ACTIVE COMPARATORPatients receive trifluridine and tipiracil hydrochloride PO BID on days 1-5 and 8-12, or regorafenib PO QD on days 1-21, at the discretion of the treating physician. Treatment repeats every 28 days for a maximum of 24 cycles in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria
You may qualify if:
- Most recent Guardant360 blood collection date =\< 90 days prior to randomization.
- NOTE: If a patient does not have Guardant360 test results available, enrollment in ACCRU\_GI-1611 (COLOMATE) is strongly encouraged.
- Greater than 90 days has elapsed between the most recent treatment with an anti-epidermal growth factor receptor gene (EGFR) therapy (cetuximab or panitumumab) and blood collection for Guardant360 assay.
- Age \>= 18 years.
- Histologically and/or cytologically confirmed adenocarcinoma of the colon or rectum that is metastatic and/ or unresectable.
- Documented wild-type in KRAS and NRAS (codons 12, 13, 59, 61, 117, and 146) and in BRAF codon 600, based on tumor tissue taken from primary or metastatic site prior to receipt of anti EGFR therapy.
- Progression, intolerance, or contraindication to:
- A fluoropyrimidine (e.g., 5-fluorouracil or capecitabine)
- Oxaliplatin
- Irinotecan
- An anti-vascular endothelial growth factor (VEGF) monoclonal antibody (including but not limited to bevacizumab, ramucirumab, or aflibercept).
- If the tumor has deficient mismatch repair proteins (dMMR) or is microsatellite instability (MSI)-high based on tumor tissue testing, an anti-programmed death (PD)-1 monoclonal antibody (including but not limited to nivolumab or pembrolizumab).
- Clinical or radiographic progression after treatment with an anti-EGFR monoclonal antibody (cetuximab and/or panitumumab) for at least 3 months (minimum of 6 biweekly treatments or 12 weekly treatments at full or partial dose).
- NOTE: Treatments do not need to be administered consecutively.
- NOTE: Dose reductions or delays are permitted.
- +19 more criteria
You may not qualify if:
- Radiation therapy, hormonal therapy, biologic therapy, experimental therapy, or chemotherapy for cancer \< 21 days prior to randomization.
- Therapeutic anticoagulation with Vitamin-K antagonists (e.g., warfarin).
- Maximum mutant allele frequency (highest allele frequency reported for any gene mutation) (MAF) less than 0.5% by Guardant360 assay.
- Detection of at least one of the following gene mutation(s) or amplification(s) by Guardant360 assay.
- BRAFV600E mutation (mutant allele frequency (MAF) \>= 0.5% or amplification.
- ERBB2 (HER2) amplification.
- KRAS mutation (MAF \>= 0.5%) or amplification.
- MET amplification.
- NRAS mutation (MAF \>= 0.5%) or amplification.
- Prior treatment with both TAS-102 and regorafenib (prior treatment with either TAS-102 or regorafenib is permitted).
- Unable to swallow oral tablets (crushing of study treatment tablets is not allowed).
- Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens. Note: This includes impaired heart function or clinically significant heart disease.
- Not recovered to baseline or Common Terminology for Adverse Events (CTCAE) version (v)5.0 =\< grade 1 from toxicity due to all prior therapies except alopecia, oxaliplatin-related neuropathy, asymptomatic electrolyte abnormalities, and other non-clinically significant adverse events.
- Any of the following because this study involves an agent that has known genotoxic, mutagenic and teratogenic effects:
- Pregnant women.
