This phase I trial studies the side effects and best dose of CA-4948 when given together with fluorouracil, leucovorin, oxaliplatin (FOLFOX) plus bevacizumab in treating patients with colorectal cancer that has spread from where it first started (primary site) to other places in the body (metastatic). CA-4948 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The chemotherapy drugs used in FOLFOX, fluorouracil and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Leucovorin is used with fluorouracil to treat colorectal cancer. Bevacizumab is in a class of medications called anti-angiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to the tumor. This may slow the growth and spread of the tumor. Giving CA-4948 with FOLFOX plus bevacizumab may be safe, tolerable and/or effective in treating patients with metastatic colorectal cancer.
PRIMARY OBJECTIVES: I. To assess dose-limiting toxicities (DLTs) and determine the recommended phase 2 dose (RP2D) of CA-4948 (emavusertib) in combination with leucovorin (folinic acid), fluorouracil, and oxaliplatin (FOLFOX) plus bevacizumab in first-line treatment for patients with advanced or metastatic non-operable colorectal cancer (mCRC). II. To evaluate the safety and tolerability of the combination of CA-4948 (emavusertib) and FOLFOX plus bevacizumab. SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity. II. To evaluate ribonucleic acid sequencing (RNAseq) data to examine the impact of interleukin 1 receptor associated kinase 4 (IRAK4) inhibition on downstream signaling in tumor samples. EXPLORATORY OBJECTIVES: I. To evaluate pharmacodynamic (PD) effect of CA-4948 (emavusertib) in combination with chemotherapy. II. To evaluate pharmacokinetics (PKs) of CA-4948 (emavusertib) in combination with chemotherapy. III. To explore biomarkers and genomic alterations associated with treatment response. IV. To evaluate if certain gene mutations alone or in combination are associated with response, progression free survival (PFS), and/or overall survival (OS). OUTLINE: This is a dose-escalation study of CA-4948 in combination with FOLFOX plus bevacizumab followed by a dose-expansion study. Patients are assigned to 1 of 2 groups. GROUP A: Patients receive CA-4948 orally (PO) twice daily (BID) on days 1-14 of each cycle, bevacizumab intravenously (IV) over 30-90 minutes on day 1 of each cycle beginning in cycle 1, and oxaliplatin IV over 120 minutes, leucovorin calcium (leucovorin) IV over 2 hours, and fluorouracil IV bolus followed by continuous IV infusion over 46 hours on day 1 of each cycle. Cycles repeat every 14 days for up to 2 years in the absence of disease progression or unacceptable toxicity. After treatment for 2 years, patients may continue treatment after discussion with the study chair. Patients also undergo blood sample collection and computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET)/CT throughout the trial. Patients may also undergo tumor biopsy throughout the trial. GROUP B: Patients receive CA-4948 PO BID on days 1-14 of each cycle, bevacizumab IV over 30-90 minutes on day 1 of each cycle beginning in cycle 2, and oxaliplatin IV over 120 minutes, leucovorin IV over 2 hours, and fluorouracil IV bolus followed by continuous IV infusion over 46 hours on day 1 of each cycle. Cycles repeat every 14 days for up to 2 years in the absence of disease progression or unacceptable toxicity. After treatment for 2 years, patients may continue treatment after discussion with the study chair. Patients also undergo blood sample collection and CT, MRI, or PET/CT throughout the trial. Patients also undergo tumor biopsy throughout the trial. After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 12 months after end of treatment.

Dose limiting toxicities (DLT)
DLT will be based on the first 2 cycles (28 days) of emavusertib.
Time frame: Up to 2 cycles (Cycle length = 14 days)
Incidence of treatment-emergent adverse events
The adverse events will be recorded by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0.
Time frame: Up to 2 cycles (Cycle length = 14 days)
Incidence of adverse events
Adverse events, graded according to the National Cancer Institute CTCAE v5 for each cohort, will be analyzed using descriptive statistics.
Time frame: Baseline to 30 days after last dose of study drug
Overall response rate
Defined as the percentage of patients who achieve complete response (CR) or partial response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1.
Time frame: From the start of treatment until disease progression/recurrence, assessed up to 12 months after end of treatment
Progression free survival
Will be assessed using RECIST v1.1.
Time frame: From first dose to the earlier date of assessment of progression or death by any cause in the absence of progression, assessed up to 12 months after end of treatment
Overall survival
Time frame: From the date of first dose to the date of death by any cause, assessed up to 12 months after end of treatment
Disease control rate
Defined as the percentage of patients who achieve a best response of CR, PR, or stable disease (SD) per RECIST v1.1 at any time during their treatment. A determination of SD requires that the first restaging imaging scan be performed after 4 cycles of treatment (8 weeks from start of treatment +/- 7 days).
Time frame: Up to 12 months after end of treatment
Molecular profiling
Molecular profiling by next generation sequencing will be done to assess the impact of IRAK4 inhibition on downstream signaling in tumor samples.
Time frame: At baseline, between cycle (C) 1 day (D) 10 and C1D14, and disease progression
