Inclusion Criteria:

* Disease indication

  * Must have disease that is relapsed or refractory or be intolerant to standard-of-care therapies and should have no appropriate standard-of-care therapeutic option.

    * Non-small cell lung cancer (NSCLC)
    * HER2 negative breast cancer
    * Ovarian cancer
    * Cervical cancer
    * Endometrial cancer
    * Esophageal cancer
    * Gastric cancer and GEJ carcinoma
    * Colorectal cancer
    * Exocrine pancreatic adenocarcinoma
    * Appendiceal adenocarcinoma and pseudomyxoma peritonei of unknown origin
* Participants enrolled in the following study parts should have an appropriate tumor site that satisfies the following criteria:

  * Site has tumor that is not a target lesion and has not been previously irradiated (unless progression has occurred since end of radiotherapy)
  * Site has tumor that is accessible for a minimally invasive biopsy that does not present a significant risk, AND
  * Participant must agree to a biopsy as follows

    * Disease-specific expansion cohorts: pre-treatment biopsy, unless medically infeasible following consultation with the medical monitor
    * Biology expansion cohort: pretreatment biopsy (required) and additional on-treatment biopsy during Cycle 1 (unless medically infeasible following consultation with the medical monitor)
* Measurable disease per the Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) at baseline
* An Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1
* Adequate renal, hepatic, and hematologic function

Exclusion Criteria

* History of another malignancy within 3 years before the first dose of study drug, or any evidence of residual disease from a previously diagnosed malignancy.
* Known active central nervous system metastases
* Carcinomatous meningitis
* Previous receipt of monomethylauristatin E (MMAE)-containing drugs
* Pre-existing neuropathy ≥ Grade 2 per the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0
* Any uncontrolled ≥ Grade 3 (per the NCI CTCAE, Version 5.0) viral, bacterial, or fungal infection within 2 weeks prior to the first dose of SGN-STNV

There are additional inclusion and exclusion criteria. The study center will determine if criteria for participation are met.

Outcome Measures

Primary Outcomes

Incidence of adverse events (AEs)

To be summarized using descriptive statistics

Time frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years

Incidence of laboratory abnormalities

To be summarized using descriptive statistics

Time frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years

Incidence of dose limiting toxicities

To be summarized using descriptive statistics

Time frame: Up to 28 days

Secondary Outcomes

Objective response rate (ORR) as assessed by the investigator per RECIST v1.1

ORR is defined as the proportion of subjects achieving a partial response (PR) or complete response (CR).

Time frame: Up to approximately 3 years

Progression-free survival (PFS)

PFS is defined as the time from the start of any study treatment to first documentation of disease progression or to death due to any cause, whichever comes first.

Time frame: Up to approximately 3 years

Overall survival (OS)

OS is defined as the time from the start of any study treatment to the date of death due to any cause.

Time frame: Up to approximately 3 years

Duration of objective response (DOR)

DOR is defined as the time from start of the first documentation of objective tumor response (CR or PR) to the first documentation of tumor progression or to death due to any cause, whichever comes first.

Time frame: Up to approximately 3 years

Area under the concentration-time curve (AUC)

Pharmacokinetic (PK) endpoint

Time frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years

Time to maximum concentration (Tmax)

PK endpoint

Time frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years

Maximum concentration (Cmax)

PK endpoint

Time frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years

Trough concentration (Ctrough)

PK endpoint

Time frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years

Incidence of antidrug antibodies (ADA)

Immunogenicity endpoint

Time frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years
