Brief Summary:
This trial will study ladiratuzumab vedotin (LV) to find out if it works to treat different types of solid tumors. It will also find out what side effects may occur. A side effect is anything the drug does besides treating cancer.

Condition or disease Intervention/treatment Phase
Small Cell Lung Cancer Non-small Cell Lung Cancer, Squamous Non-small Cell Lung Cancer, Non-squamous Head and Neck Squamous Cell Carcinoma Esophageal Squamous Cell Carcinoma Gastric Adenocarcinoma Gastroesophageal Junction Adenocarcinoma Prostate Cancer Melanoma Drug: ladiratuzumab vedotin Phase 2

Detailed Description:

This trial is designed to assess the antitumor activity, safety, and tolerability of LV for the treatment of solid tumors. Participants with the following advanced solid tumors will be enrolled:

Cohort 1: small cell lung cancer (SCLC) Cohort 2: non-small cell lung cancer-squamous (NSCLC-squamous) Cohort 3: non-small cell lung cancer-nonsquamous (NSCLC-nonsquamous) Cohort 4: head and neck squamous cell carcinoma (HNSCC) Cohort 5: esophageal squamous cell carcinoma (esophageal-squamous) Cohort 6: gastric and gastroesophageal junction (GEJ) adenocarcinoma Cohort 7: castration-resistant prostate cancer (CRPC) Cohort 8: melanoma

Participants will continue to receive study treatment until disease progression, unacceptable toxicity, investigator decision, consent withdrawal, study termination by the sponsor, pregnancy, or death, whichever comes first.

Primary Outcome Measures :
  1. Confirmed objective response rate (ORR) as determined by investigator according to RECIST v1.1 [ Time Frame: Up to approximately 1 year ]
    Confirmed ORR is defined as the proportion of participants who achieve a confirmed complete response (CR) or partial response (PR) according to RECIST v1.1 as assessed by the investigator.

  2. Prostate-specific antigen (PSA) response rate as determined by investigator according to Prostate Cancer Clinical Trials Working Group 3 criteria (Cohort 7 only) [ Time Frame: Up to approximately 1 year ]
    Confirmed PSA response rate is defined as the proportion of participants with a reduction from baseline PSA level of at leat 50%, measured twice ≥3 weeks apart


Secondary Outcome Measures :
  1. Number of participants with adverse events (AEs) [ Time Frame: Up to approximately 1 year ]
  2. Disease control rate (DCR) as determined by investigator according to RECIST v1.1 [ Time Frame: Up to approximately 1 year ]
    DCR is defined as the proportion of participants who achieve a confirmed CR or PR, or meet the stable disease (SD) criteria at least once after start of study treatment at a minimum interval of 5 weeks.

  3. Duration of response (DOR) as determined by investigator according to RECIST v1.1 [ Time Frame: Up to approximately 1 year ]
    DOR is defined as the time from the first documentation of objective response (CR or PR that is subsequently confirmed) to the first documentation of progressive disease (PD) or death due to any cause, whichever comes first.

  4. PSA-DOR as determined by investigator assessment (Cohort 7 only) [ Time Frame: Up to approximately 1 year ]
    PSA-DOR is defined as the time from the first documentation of PSA response to the first documentation of PSA progression or death, whichever comes first

  5. Progression-free survival (PFS) as determined by investigator according to RECIST v1.1 [ Time Frame: Up to approximately 1 year ]
    Progression-free survival (PFS) is defined as the time from the start of study treatment to the first documentation of PD or death due to any cause, whichever comes first.

  6. PSA-PFS as determined by investigator assessment (Cohort 7 only) [ Time Frame: Up to approximately 1 year ]
    PSA-PFS is defined as the time from the start of study treatment to first occurrence of PSA progression or death, whichever comes first

  7. Overall survival (OS) [ Time Frame: Up to approximately 1 year ]
    OS is defined as the time from the start of study treatment to date of death due to any cause.

  8. Maximum observed concentration (Cmax) [ Time Frame: Up to approximately 1 year ]
    Pharmacokinetic (PK) endpoint of LV

  9. Area under the concentration-time curve (AUC) [ Time Frame: Up to approximately 1 year ]
    PK endpoint of LV

  10. Incidence of antitherapeutic antibodies (ATAs) to LV [ Time Frame: Up to approximately 1 year ]
