Phase 1
Terminated
Conditions
Non-small Cell Lung Cancer
Gastric Carcinoma
Gastroesophageal Junction Carcinoma
Classical Hodgkin Lymphoma
Diffuse Large B-cell Lymphoma
Peripheral T-cell Lymphoma
Cutaneous Melanoma
Head and Neck Squamous Cell Carcinoma

Interventions
Registration Number
NCT04254107
Lead Sponsor
Seagen Inc.
Brief Summary

This trial will look at a drug called SEA-TGT (also known as SGN-TGT) to find out whether it is safe for patients with solid tumors and lymphomas. It will study SEA-TGT to find out what its side effects are. A side effect is anything the drug does besides treating cancer. It will also study whether SEA-TGT works to treat solid tumors and lymphomas.

The study will have four parts. Part A of the study will find out how much SEA-TGT should be given to patients. Part B will use the dose found in Part A to find out how safe SEA-TGT is and if it works to treat solid tumors and lymphomas. Part C will study how well SEA-TGT with sasanlimab works to treat solid tumors. Part D will study how well SEA-TGT with brentuximab vedotin works to treat classical Hodgkin lymphoma (cHL).

Primary Outcome Measures
NameTimeMethod
Number of participants with a dose-limiting toxicity (DLT) at each dose levelUp to 21 days

Number of participants with adverse events (AEs)Through 45-52 days following last dose of SEA-TGT; up to approximately 3 years

An AE is any untoward medical occurrence in a subject or clinical investigational subject administered a medicinal product and which does not necessarily have a causal relationship with this treatment.

Number of participants with laboratory abnormalities by gradeThrough 45-52 days following last dose of SEA-TGT; up to approximately 3 years

To be summarized using descriptive statistics

Secondary Outcome Measures

Duration of overall survivalUp to approximately 3 years

Time from start of study treatment to the date of death due to any cause

Area under the concentration-time curve (AUC)Through 45-52 days following last dose of SEA-TGT; up to approximately 3 years

Time to maximum concentration (tmax)Through 45-52 days following last dose of SEA-TGT; up to approximately 3 years

To be summarized using descriptive statistics.

Complete response (CR) rateUp to approximately 3 years

Proportion of participants with CR per the participant's specific tumor response criteria

Duration of objective responseUp to approximately 3 years

Time from first response to the first documentation of disease progression or death due to any cause

Maximum concentration (Cmax)Through 45-52 days following last dose of SEA-TGT; up to approximately 3 years

To be summarized using descriptive statistics.

Trough concentration (Ctrough)Through 45-52 days following last dose of SEA-TGT; up to approximately 3 years

To be summarized using descriptive statistics.

Duration of CRUp to approximately 3 years

Time from start of the first documentation of CR to the first documentation of confirmed tumor progression or to death due to any cause, whichever comes first

Duration of progression-free survivalUp to approximately 3 years

Time from first dose to the first documentation of disease progression or death due to any cause
