Key Eligibility Criteria:

Inclusion:
1. For Phase 1b: locally advanced, recurrent, or metastatic, incurable, and histologically or cytologically confirmed HR+/HER2- breast cancer by ASCO/CAP criteria (based on most recent assessment):
a) Must have received CDK4/6i in the adjuvant or metastatic setting, unless patient was unable or unwilling to receive standard of care CDK4/6i treatment; or must be able to receive it on protocol, AND,
b) Received no more than 1 prior line of therapy containing chemotherapy (including cytotoxic antibody-drug conjugates) given in the metastatic setting; AND,
c) Must have received no more than 3 lines of therapy in total for metastatic disease.
d) May have received a prior PI3Ka inhibitor

NOTE: If the patient progressed on the PI3K inhibitor a sample (tissue or liquid) must have been obtained following progression, or at study screening, to be analyzed at a CAP/CLIA-certified or equivalently accredited diagnostic laboratory, determine the resistance mutation(s) and Sponsor approval for study inclusion obtained. If the patient was intolerant to the drug, then mutational analysis and Sponsor approval are not required for enrollment.

Exclusion:
1. Has had tumor evaluated for PTEN and AKT and has known mutations or deletions in PTEN, or, activating mutations in AKT (E17K) determined at a CAP/CLIA-certified or equivalently accredited diagnostic laboratory (e.g., ISO15189-certified, in-house clinical testing).
2. Metaplastic breast cancer
3. Possible allergies to TOS-358 or excipients

Exclusion Criteria:

1. Active or chronic corneal disorder including, but not limited to, Sjogren's syndrome, Fuchs corneal dystrophy (requiring treatment), history of corneal transplantation, active herpetic keratitis, and/or active ocular conditions requiring ongoing treatment/monitoring such as wet age-related macular degeneration requiring intravitreal injections, active diabetic retinopathy with macular edema, presence of papilledema, and acquired monocular vision
2. History of allergic reactions attributed to compounds of similar chemical or biologic composition to the ADCs used in the study
3. History of interstitial lung disease or pneumonitis requiring steroid therapy

Key Eligibility Criteria:
Inclusion Criteria:
1. Fresh pre-treatment and on-treatment tumor biopsy must be provided for biomarker analysis.
2. Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 and at least 1 lesion accessible for biopsy. Fine needle biopsy, cytology, and bone lesion biopsies are not acceptable.
3. Radiographically documented progressive disease on or after the most recent therapy.
4. Received standard-of-care therapies, (except for Part 1C, 2C and 2D, where participants with prior docetaxel use for the advanced/metastatic setting will be excluded), including an available programmed death (ligand)-1 inhibitor known to be effective in the tumor type for which they are being evaluated.
5. Advanced or metastatic disease and have received, be refractory to, not be a candidate for, or be intolerant of existing therapies known to provide clinical benefit for the condition of the participant.
6. Histologically confirmed NSCLC meeting stage criteria for stage IIIB, stage IV, or recurrent disease.

Exclusion Criteria:
1. Primary central nervous system (CNS) malignancy.
2. Untreated CNS metastases.
3. Concurrent malignancy requiring treatment or history of prior malignancy active within 2 years prior to the first dose of study treatment.
4. Active, known, or suspected autoimmune disease.
5. Condition requiring systemic treatment with either corticosteroids within 14 days or other immunosuppressive medications within 30 days of the first dose of study treatment.
6. History of or with active interstitial lung disease or pulmonary fibrosis.
