Sym023 (Anti-TIM-3) in Patients With Advanced Solid Tumor Malignancies or Lymphomas
October 11, 2021 updated by: Symphogen A/S
A Phase 1, Open-Label, Multicenter Trial Investigating the Safety, Tolerability, and Preliminary Antineoplastic Activity of Sym023 (Anti-TIM-3) in Patients With Advanced Solid Tumor Malignancies or Lymphomas
This was the first study to test Sym023 in humans.
The primary purpose of this study was to see if Sym023 is safe and tolerable for patients with locally advanced/unresectable or metastatic solid tumor malignancies or lymphomas that are refractory to available therapy or for which no standard therapy is available.

Detailed Description
This study evaluated the preliminary safety, tolerability, and dose-limiting toxicities (DLTs) of Sym023, a recombinant, fully human, anti-T-cell immunoglobulin and mucin-domain containing-3 (anti-TIM-3) monoclonal antibody (mAb).
The goal was to establish the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of sequential escalating doses of Sym023 when administered once every 2 weeks (Q2W) by intravenous (IV) infusion to patient cohorts with locally advanced/unresectable or metastatic solid tumor malignancies or lymphomas that are refractory to available therapy or for which no standard therapy is available.
If an MTD was not identified, a maximum administered dose (MAD) was to be determined.
Sym023 was given to patients in escalating dose cohorts; each patient was given one fixed dose level.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assessment of Treatment Emergent Adverse Events (AEs) Meeting Dose-limiting Toxicity (DLT) Criteria.
Time Frame: 28 days
|
Assess the safety and tolerability of Sym023 on a Q2W (once every 2 weeks) schedule to establish the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D).
Assessment based on the occurrence of AEs meeting DLT criteria measured during Cycle 1.
The MTD was to be determined by those DLTs that occurred during C1 in either more than 1 patient in a 3 to 6 patient cohort or ≥33.3% of patients in the event of an expanded 7 to 12 patient cohort.
One patient in the 10.0 mg/kg dose cohort was not evaluable for MTD as she did not complete C1 for a reason other than drug toxicity (i.e., discontinuation after 1 dose due to patient withdrawal of consent).
However, this patient was included in the evaluation of other outcomes.
