Brief Summary

This clinical trial is evaluating a drug called BT8009 alone and in combination with nivolumab in participants with advanced solid tumors associated with Nectin-4 expression or in participants with advanced solid tumor malignancies having renal insufficiency. The main goals of this study are to: - Find the recommended dose of BT8009 that can be given safely to participants alone and in combination with nivolumab - Learn more about the side effects and effectiveness of BT8009 alone and in combination with nivolumab - Learn more about BT8009 alone and in combination with nivolumab - Learn more about BT8009 alone in patients with kidney disease

Detailed Description


BT8009 consists of a Bicycle peptide (Bicycle®) which binds selectively to Nectin-4, and is
covalently attached to a spacer and a cleavable linker attached to a cytotoxin (MMAE).

This study is a Phase I/II, multicenter, first-in-human, open-label dose-escalation study of
BT8009 given as a single agent given once weekly and in combination with nivolumab. There are
three parts to this study. Part A is a dose escalation in patients with select advanced solid
tumors primarily designed to evaluate safety and tolerability of BT8009 as monotherapy or in
combination with nivolumab and to determine a recommended Phase II dose (RP2D). Following a
selection of a recommended Phase II dose (RP2D), part B, a dose expansion portion, will be
initiated with the primary objective of clinical activity of BT8009 as a monotherapy or in
combination with nivolumab in patients with select advanced solid tumors. Part C will
evaluate safety and tolerability of chosen RP2D of BT8009 in patients with renal
insufficiency.

Primary Outcomes:

Primary Outcome 1 - Measure: Cohorts A-1, A-2 and C: Number of participants with treatment emergent adverse events receiving BT8009 alone and in combination with nivolumab to assess safety and tolerability

Primary Outcome 1 - Time Frame: From cycle 1 day 1 until 30 days after the end of treatment (each cycle is 28 days)

Primary Outcome 2 - Measure: Cohort A-1 and A-2 (escalations): Number of participants with dose limiting toxicities on BT8009 alone and in combination with nivolumab

Primary Outcome 2 - Time Frame: From cycle 1 day 1 to the end of cycle 1 (each cycle is 28 days)

Primary Outcome 3 - Measure: Cohort B-1 and B-2 (expansions): Objective response rate (ORR) to assess the clinical activity of BT8009 as a monotherapy and in combination with nivolumab

Primary Outcome 3 - Time Frame: Every 8 weeks for 12 months then every 12 weeks thereafter until disease progression or death or up to three years

Primary Outcome 4 - Measure: Cohort B-1 and B-2 (expansions): Duration of response to assess the clinical activity of BT8009 as a monotherapy and in combination with nivolumab

Primary Outcome 4 - Time Frame: Every 8 weeks for 12 months then every 12 weeks thereafter until disease progression or death or up to three years

Primary Outcome 5 - Measure: Cohort B-1 and B-2 (expansions): Clinical benefit rate to assess the clinical activity of BT8009 as a monotherapy and in combination with nivolumab

Primary Outcome 5 - Time Frame: Every 8 weeks for 12 months then every 12 weeks thereafter until disease progression or death or up to three years

Primary Outcome 6 - Measure: Cohort B-1 and B-2 (expansions): Time to tumor progression to assess the clinical activity of BT8009 as a monotherapy and in combination

Primary Outcome 6 - Time Frame: Every 8 weeks for 12 months then every 12 weeks thereafter until disease progression or death or up to 3 years

Primary Outcome 7 - Measure: Cohort B-1 and B-2 (expansions): Progression free survival time to assess the clinical activity of BT8009 as a monotherapy and in combination with nivolumab

Primary Outcome 7 - Time Frame: Every 8 weeks for the first 12 months then every 12 weeks until disease progression or death for up to three years

Primary Outcome 8 - Measure: Cohort B-1 and B-2 (expansions): Progression free survival rate at 6 months to assess the clinical activity of BT8009 as a monotherapy and in combination with nivolumab using RECIST 1.1

Primary Outcome 8 - Time Frame: Every 8 weeks after cycle 1 day 1 for 6 months (each cycle is 28 days)

Primary Outcome 9 - Measure: Cohort B-1 and B-2 (expansions): Overall survival rate at 12 months to assess the clinical activity of BT8009 as a monotherapy and in combination with nivolumab using RECIST 1.1

Primary Outcome 9 - Time Frame: Every 3 months for up to 1 year
