Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - etrumadenant
Treatment: Drugs - mFOLFOX

Experimental: Dose Escalation - Dose escalation is a 3+3 design, including a Dose Limiting Toxicity (DLT) evaluation period. The RDE of etrumadenant will be determined in this part with escalating doses of etrumadenant in combination with the standard mFOLFOX chemotherapy regimen in participants with gastroesophageal or colorectal cancer.

Experimental: Dose Expansion-GE - The RDE of etrumadenant will be determined from the dose escalation part. Etrumadenant will be given in combination with the standard mFOLFOX chemotherapy regimen in participants with gastroesophageal cancer

Experimental: Dose Expansion-CRC - The RDE of etrumadenant will be determined from the dose escalation part. Etrumadenant will be given in combination with the standard mFOLFOX chemotherapy regimen in participants with colorectal cancer


Treatment: Drugs: etrumadenant
Etrumadenant is an A2aR and A2bR antagonist.

Treatment: Drugs: mFOLFOX
Oxaliplatin, Leucovorin and 5-fluorouracil given as part of standard mFOLFOX chemotherapy regimen

Eligibility
Key inclusion criteria
* Male or female participants = 18 years
* Histologically confirmed gastroesophageal cancer or colorectal cancer that is metastatic, advanced or recurrent with progression
* Participants for whom mFOLFOX is considered appropriate therapy
* Must have at least 1 measurable lesion per RECIST v1.1.
* Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1.
* Must have received standard of care, including potentially curative available therapies or interventions.
* Confirm that an archival tissue sample is available and = 24 months old; if not, a new biopsy of a tumor lesion must be obtained.
* Adequate organ and marrow function
* Previously treated central nervous system metastases, meeting the following criteria:

* No evidence of progression by magnetic resonance imaging for at least 4 weeks prior to first dose.
* Neurologic symptoms returned to baseline.
* No immunosuppressive doses of systemic corticosteroids for at least 2 weeks before investigational product administration.
* No carcinomatous meningitis.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Use of any live vaccines against infectious diseases (eg, influenza, varicella) within 4 weeks (28 days) of initiation of investigational product.
* Underlying medical conditions that, in the Investigator's or Sponsor's opinion, will make the administration of investigational product hazardous (eg interstitial lung disease, active infections requiring antibiotics, recent hospitalization with unresolved symptoms) or obscure the interpretation of toxicity determination or AEs, or concurrent medical condition requiring the use of immunosuppressive medications or immunosuppressive doses of systemic or absorbable topical corticosteroids.
* Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
* Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the pre-screening or screening visit through 30 days after the last dose of etrumadenant in combination with mFOLFOX.
* Any active autoimmune disease or a documented history of autoimmune disease or syndrome that required systemic treatment in past 2 years (ie, with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs), except for vitiligo or resolved childhood asthma/atopy.

* Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment.
* Participants with asthma who require intermittent use of bronchodilators, inhaled corticosteroids, or local corticosteroid injections will not be excluded from this study. Participants on chronic systemic corticosteroids will be excluded from the study.
* Prior malignancy active within the previous 2 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix, breast, or prostate.
* Prior chemotherapy, targeted small-molecule therapy, or radiation therapy within 4 weeks prior to Day 1 or has not recovered (ie, = Grade 1 or baseline) from AEs due to a previously administered agent, except = Grade 2 alopecia or = Grade 2 neuropathy and other AEs = Grade 2 considered not clinically significant by the Medical Monitor and Investigator.
* Use of other investigational drugs (drugs not marketed for any indication) within 28 days of investigational product administration.
