Brief Summary:

This trial will look at a drug called SGN-STNV to find out whether it is safe for patients with solid tumors. It will study SGN-STNV to find out what its side effects are. A side effect is anything the drug does besides treating cancer. It will also study how well SGN-STNV works to treat solid tumors.

The study will have two parts. Part A of the study will find out how much SGN-STNV should be given to patients. Part B will use the dose found in Part A to find out how safe SGN-STNV is and if it works to treat certain types of solid tumors.


Condition or disease Intervention/treatment Phase
Carcinoma, Non-Small Cell Lung HER2 Negative Breast Neoplasms Ovarian Neoplasms Uterine Cervical Neoplasms Endometrial Neoplasms Esophageal Neoplasms Gastroesophageal Junction Carcinoma Stomach Neoplasms Colorectal Neoplasms Exocrine Pancreatic Adenocarcinoma Appendiceal Adenocarcinoma Pseudomyxoma Peritonei Drug: SGN-STNV Phase 1

Detailed Description:
The study will include dose escalation (Part A) and dose expansion (Part B), with multiple disease-specific cohorts and a biology cohort in dose expansion. The biology cohort will require additional biopsies. At the completion of dose escalation, up to 5 disease specific expansion cohorts and 1 biology expansion cohort may be activated by the sponsor in consultation with the Safety Monitoring Committee (SMC). Expansion cohorts in Part B will enroll subjects with selected tumors that are eligible for enrollment in Part A. The dose(s) to be examined in Part B will be at or below the maximum tolerated dose and/or the recommended dose determined in Part A. The recommended dose and/or schedule may differ between cohorts.

Primary Outcome Measures :
  1. Incidence of adverse events (AEs) [ Time Frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years ]
    To be summarized using descriptive statistics

  2. Incidence of laboratory abnormalities [ Time Frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years ]
    To be summarized using descriptive statistics

  3. Incidence of dose limiting toxicities [ Time Frame: Up to 28 days ]
    To be summarized using descriptive statistics


Secondary Outcome Measures :
  1. Objective response rate (ORR) as assessed by the investigator per RECIST v1.1 [ Time Frame: Up to approximately 3 years ]
    ORR is defined as the proportion of subjects achieving a partial response (PR) or complete response (CR).

  2. Progression-free survival (PFS) [ Time Frame: Up to approximately 3 years ]
    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.

  3. Overall survival (OS) [ Time Frame: Up to approximately 3 years ]
    OS is defined as the time from the start of any study treatment to the date of death due to any cause.

  4. Duration of objective response (DOR) [ Time Frame: Up to approximately 3 years ]
    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.

  5. Area under the concentration-time curve (AUC) [ Time Frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years ]
    Pharmacokinetic (PK) endpoint

  6. Time to maximum concentration (Tmax) [ Time Frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years ]
    PK endpoint

  7. Maximum concentration (Cmax) [ Time Frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years ]
    PK endpoint

  8. Trough concentration (Ctrough) [ Time Frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years ]
    PK endpoint

  9. Incidence of antidrug antibodies (ADA) [ Time Frame: Through 30-37 days following last dose of SGN-STNV; up to approximately 3 years ]
    Immunogenicity endpoint
