Brief Summary

This study will evaluate the safety, PK profile, and anti-cancer efficacy of SC-102 in subjects with advanced solid tumors

Conditions

Advanced Solid Cancers

Outcome Measures

Primary Outcomes (3)

• Number of participants receiving SC-102 treatment with treatment-emergent adverse events (escalation study)

  Safety reported as incidence of treatment-emergent adverse events

  From Cycle 1 Day 1 (each cycle is 28 days) until 30 days post last dose

• Maximum tolerated dose (MTD) by the number of participants with dose limiting toxicities from SC-102 treatment (escalation study)

  Maximum Tolerated Dose (MTD)

  At the end of Cycle 1 (each cycle is 28 days)

• Objective response rate by RECIST 1.1 in participants with solid tumors receiving SC-102 treatment (expansion study)

  Defined as the percentage of subjects who experience a best response of either complete response (CR) or partial response (PR).

  From Cycle 1 Day 1 (each cycle is 28 days) until the date of first documented progression, death from any cause, start treatment of new anti-cancer agent(s), loss of follow-up, or withdrawal of consent, which ever came first, assessed up to 2 years

Secondary Outcomes (7)

• Maximum plasma concentration (Cmax) of SC-102 and monomethyl auristatin E (MMAE)

  From Cycle 1 Day 1 through the end of treatment from any cause, assessed up to 2 years

• Minimum plasma concentration (Cmin) of SC-102 and monomethyl auristatin E (MMAE)

  From Cycle 1 Day 1 through the end of treatment from any cause, assessed up to 2 years

• Area under the plasma concentration-time curve (AUC) of SC-102 and monomethyl auristatin E (MMAE)

  From Cycle 1 Day 1 through the end of treatment from any cause, assessed up to 2 years

• Elimination half-life (t1/2) of SC-102 and monomethyl auristatin E (MMAE)

  From Cycle 1 Day 1 through the end of treatment from any cause, assessed up to 2 years

• Number of participants positive for anti-drug antibodies (ADA)

  From Cycle 1 Day 1 through the end of treatment from any cause, assessed up to 2 years

Study Arms (2)

SC-102 for once weekly

EXPERIMENTAL

Participants will receive SC-102 as a single agent once weekly on a 4-week cycle at the selected dose.

Drug: SC-102

SC-102 for once biweekly

EXPERIMENTAL

Participants will receive SC-102 as a single agent once biweekly on a 4-week cycle at the selected dose.

Drug: SC-102

Interventions

SC-102 DRUG

SC-102 is a peptide drug conjugate (PDC) consisting an EphA2-targeting peptide, a tubulin inhibitor, and a protease-hydrolyzable linker.

SC-102 for once biweekly; SC-102 for once weekly
