Select Inclusion Criteria:

* Males or females aged ≥18 years.
* Parts 1 and 3 (escalation cohorts): Subjects with locally advanced or metastatic non resectable solid tumors, whose disease has progressed despite all standard therapies or for whom no further standard or clinically acceptable therapy exists.
* Part 2 (single-agent expansion cohort): Subjects with NSCLC, melanoma, HNSCC, G/GEA, RCC, or TCC, with histologically confirmed, locally advanced or metastatic, non-resectable disease, which has progressed despite all standard therapies including CPI or for whom no standard or clinically acceptable therapy exists.
* Part 4 (expansion cohorts in combination with pembrolizumab, with or without chemotherapy): Subjects with melanoma (all types), HNSCC, G/GEA, RCC, TCC, NSCLC, or MSI-high, TMB-high, MMR-deficient tumors, with histologically confirmed, locally advanced or metastatic, non resectable disease, which is either CPI-naive (melanoma, HNSCC, NPC) or progressed despite all standard therapies including CPI (NSCLC, RCC, TCC, uveal melanoma, MSI-high, TMB-high, or MMR-deficient solid tumors) or for whom no standard or clinically acceptable therapy exists.
* For Cohort F3 (NSCLC), subjects may have progressed on no more than 2 lines of standard therapy that must include at least one PD-1/L1 regimen.
* For Cohort F4 (HNSCC and NPC), subjects may be previously treated with no more than 1 prior chemotherapy regimen in metastatic setting. Prior PD-1/L1 in curative (neo-adjuvant/adjuvant) setting is allowed only if completed \>/= 6 months prior to progression to local recurrence or metastatic disease.
* For Cohort F8, subjects must have previously untreated, histologically confirmed Stage II, IIIA or IIIB (T3-4N2) NSCLC. Lymph node disease requires histologic confirmation, while T3 disease requires only radiographic documentation. Subjects need to be able to undergo planned surgery.
* All subjects with non-squamous NSCLC must have documentation of absence of tumor activating EGFR mutations and absence of ALK gene rearrangements.
* PD-L1 by IHC (22C3): Parts 1 and 3: IHC optional. Part 2: IHC result mandatory but any score allowed. Combined Positive Score (CPS) ≥ 1% (or Tumor Proportion Score ≥50% for NSCLC; for TMB-high tumors, any TPS% is allowed). Part 4: Combined Positive Score (CPS) ≥ 1% (or Tumor Proportion Score ≥50% for NSCLC; for TMB-high tumors, any TPS% is allowed). For Cohort F8, any TPS (including 0%) is acceptable.
* Adequate hematologic, coagulation, hepatic and renal function and ECOG score as defined per protocol.

Select Exclusion Criteria:

* Prior exposure to OX40 agonists. Exposure to anti-PD-1 and/or anti PD-L2 CPIs or an agent targeting other co-stimulatory T-cell receptor pathways.
* Receipt of any investigational product or any approved anticancer drug(s) or biological product(s) within 4 weeks prior to the first dose of study drug with certain exceptions.
* Hematologic malignancies (e.g., ALL, AML, MDS, CLL, CML, NHL, Hodgkin's lymphoma and multiple myeloma)
* Prior or concurrent malignancies. Exception: Subjects with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessments of INBRX-106.
* Grade ≥ 3 immune-related adverse events (irAEs) or irAE that lead to discontinuation of prior immunotherapy. Some exceptions as defined per protocol apply.
* Active autoimmune disease or documented history of autoimmune disease that required systemic steroids or other immunosuppressive medications. Certain exceptions as defined in protocol apply.
* Diagnosis of immunodeficiency or treatment with systemic immunosuppressive medications within 7 days prior to the first dose of study drug. Certain exceptions as defined in protocol apply.
* History of hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) infection. Exceptions as defined in protocol apply.
* Active interstitial lung disease (ILD) or pneumonitis or a history of ILD or pneumonitis requiring treatment with steroids or other immunosuppressive medications.
* Clinically significant cardiac condition, including myocardial infarction, uncontrolled angina, viral myocarditis, cerebrovascular accident, or other acute uncontrolled heart disease \< 3 months prior to enrollment on this trial; left ventricular ejection fraction (LVEF) \< 50%; New York Heart Association (NYHA) Class III or IV congestive heart failure; or uncontrolled hypertension; or oxygen saturation \<92% on room air.
* Active, hemodynamically significant pulmonary embolism within 12 weeks prior to enrollment on this trial.
* Major surgery within 4 weeks prior to enrollment on this trial.
* Anti-infectious drug treatments (i.e., antibiotics) within 4 weeks prior to the first dose of study drug.
* Prior organ allograft transplantations or allogeneic peripheral blood stem cell (PBSC) or bone marrow (BM) transplantation.
* Additional in- and exclusion criteria per protocol.
