TRPH-222 [Phase 1 (discontinued)]
Identified from the Human Clinical Data
Click To Hide/Show 3 Activity Data Related to This Level
Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Objective Response Rate (ORR)
46%
Patients Enrolled
Eligible participants must be ≥18 with histologically confirmed relapsed/refractory B-cell NHL (DLBCL, FL, MZL, or MCL), ECOG 0-2. Key exclusions include leukemic lymphoma, double-/triple-hit DLBCL, prior organ transplants, significant neuropathy, cardiovascular disease, or other high-risk comorbidities per investigator assessment.
Administration Dosage
TRPH-222-100 is an open-label, multicenter study comprised of dose-escalation and dose-expansion stages. TRPH-222 was administered IV once every 3 weeks. 22 patients were enrolled in dose-escalating cohorts of TRPH-222 (0.6 mg/kg to 10 mg/kg) from DLBCL, FL, TFL, MCL and MZL histologies, and 10 patients in a dose-expansion cohort (7.5 mg/kg) focusing on DLBCL and FL histologies.

Related Clinical Trial
NCT Number NCT03682796  Clinical Status PHASE1
Clinical Description
Phase 1, Multicenter, Open-Label Study of the Antibody-Drug Conjugate TRPH-222 in Subjects With Relapsed and/or Refractory B-Cell Lymphoma
Primary Endpoint
The study aims to determine the maximum tolerated dose (MTD) of TRPH-222 over a 21-day timeframe while evaluating safety through adverse events (AEs), serious AEs (SAEs), and treatment-related AEs leading to discontinuation or death.
Other Endpoint
Tumor activity will be assessed via objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and duration of response (DOR) using Lugano criteria in NHL subtypes. Pharmacokinetic analysis (Cmax, AUC, CL, Vd, t½) will be conducted over multiple cycles, alongside anti-drug antibody (ADA) incidence monitoring.
