You may be eligible if
The participant is \>=18 years of age.
The participant has any histologically or cytologically confirmed advanced (unresectable) or metastatic solid tumor and has PD after treatment with available therapies that are known to confer clinical benefit or who are intolerant to treatment.
The participant must have an archival tumor tissue sample that is formalin-fixed and paraffin-embedded (FFPE) (blocks preferred over slides) and requested and confirmed available from offsite locations prior to dosing. The quality and quantity of the sample must be confirmed sufficient as per the Study Laboratory Manual. Participants who do not have archival tissue must agree to a new biopsy to obtain fresh tumor tissue prior to dosing.
Part 1b (PK/PDy cohort): The participant must have lesions amenable for biopsy and agree to undergo biopsies for fresh tumor tissue prior to treatment, approximately 4 to 6 weeks after treatment, and, whenever possible, at the time of PD and /or end of treatment (EOT). Serial biopsies are optional for participants in Part 1a and 1c.
Female participants must have a negative serum or urine pregnancy test within 72 hours prior to the date of the first dose of study medication if of childbearing potential or be of non-childbearing potential. Non-childbearing potential is defined as:
* Participants \>=45 years of age and has not had menses for \>1 year.
* Amenorrheic for \<2 years without a hysterectomy and oophorectomy and a follicle-stimulating hormone value in the postmenopausal range upon pre-study (screening) evaluation.
* Post hysterectomy, bilateral oophorectomy, or tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure.
Female participants of childbearing potential (that is \[ie\], those who do not meet above criteria) must agree to use 2 highly effective forms of contraception with their partners, starting with the screening visit through 150 days after the last dose of study therapy.
The participant must have an ECOG PS of \<=1.
The participant has adequate hematologic and organ function, defined as:
* Absolute neutrophil count (ANC) \>=1500 per microliter (/μL).
* Platelets \>=100,000/μL.
* Hemoglobin (Hb) \>=9 grams per deciliter (g/dL) or \>=5.6 millimoles per liter (mmol/L).
* Serum creatinine \<=1.5 times upper limit of normal (× ULN) or calculated creatinine clearance (CrCL) \>=50 milliliters per minute (mL/min) using Cockcroft-Gault equation for participants with creatinine levels \>1.5 × institutional ULN
* Total bilirubin \<=1.5 × ULN and direct bilirubin \<=1× ULN (in the event that the total bilirubin result exceeds the upper institutional limits of normal, direct bilirubin will be obtained to determine eligibility).
* AST and ALT \<=2.5 × ULN unless liver metastases are present, in which case they must be \<=5 × ULN.
* INR of PT \<=1.5 × ULN, unless participant is receiving anticoagulant therapy, then PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants; aPTT) \<= 1.5 × ULN unless participant is receiving anticoagulant therapy, then PT or PTT is within therapeutic range of intended use of anticoagulants.
The participant is \>= 18 years of age.
The participant has any histologically or cytologically confirmed CRC that is metastatic or not amenable to potentially curative resection (advanced), in the opinion of the Investigator.
The participant has a primary and/or metastatic tumor(s) that is known to be MSS, as determined locally.
The participant must have lesions amenable for biopsy and agree to undergo biopsies for fresh tumor tissue prior to treatment, approximately 4 to 6 weeks after, and, whenever possible, at EOT and/or the time of PD. If the participant has had a biopsy prior to entering the 28-day screening period, and within approximately 12 weeks of study treatment, that biopsy sample may be accepted as the Baseline fresh biopsy. Additionally, submission of sufficient high-quality archival tumor tissue is recommended, if available, to enable a longitudinal analysis of tumor biomarkers.
The participant has measurable disease by RECIST v1.1.
The participant has resolution to Grade \<=1, per CTCAE v5.0, of all clinically significant toxic effects of prior chemotherapy, surgery, radiotherapy, or hormonal therapy, with the exception of peripheral neuropathy, which must have resolved to Grade \<=2, and except where otherwise noted in the eligibility criteria.
Female participants must have a negative serum or urine pregnancy test within 72 hours prior to the date of the first dose of study medication if of childbearing potential or be of non-childbearing potential. Non-childbearing potential is defined as:
* Participants \>=45 years of age and has not had menses for \>1 year.
* Amenorrheic for \<2 years without a hysterectomy and oophorectomy and a follicle-stimulating hormone value in the postmenopausal range upon pre-study (screening) evaluation.
* Post hysterectomy, bilateral oophorectomy, or tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure.
Female participants of childbearing potential (ie, those who do not meet above criteria) must agree to use 2 highly effective forms of contraception with their partners, starting with the screening visit through 150 days after the last dose of study therapy.

* AST and ALT \<=2.5 × ULN unless liver metastases are present, in which case they must be \<=5 × ULN.
* INR of PT \<=1.5 × ULN, unless participant is receiving anticoagulant therapy, then PT or PTT is within therapeutic range of intended use of anticoagulants; aPTT) \<= 1.5 × ULN unless participant is receiving anticoagulant therapy, then PT or PTT is within therapeutic range of intended use of anticoagulants.
