A Study of Simmitinib Plus SG001 in Advanced Solid Tumors

Официальное название

A Phase I/II Study To Evaluate The Safety, Tolerability, Pharmacokinetic Profile And Preliminary Efficacy Of Simmitinib Plus SG001 in Patients With Advanced Solid Tumors

Обзор

This is an open-label Phase I/II trial of simmitinib plus SG001 in patients with advanced solid tumors. Phase I will determine and confirm the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) for simmitinib in combination with SG001 in patients with advanced solid tumors. Phase 2 (Expansion) will evaluate the safety and efficacy of the combination in 3 cohorts at the RP2D from Phase I.

Вмешательства

• Препарат Simmitinib
  Patients will oral administration according to study protocol until disease progression, death, unacceptable toxicity, loss of follow-up, withdrawal of consent or other conditions meet the end of treatment criteria.
• Препарат SG001
  Patients will receive intravenous infusion of SG001 according to study protocol until disease progression, unacceptable toxicity, meeting the suspension or termination criteria, or up to 24 months in patients without disease progression.
