TRACON Pharmaceuticals Presents Data from a Phase 1 Study of Uliledlimab (TJ004309) and Tecentriq® (Atezolizumab) at the American Society of Clinical Oncology Virtual Annual Meeting
In poster presentation 2511 entitled, “The safety, pharmacokinetics (PK), pharmacodynamics (PD) and clinical efficacy of uliledlimab (TJ004309), a differentiated CD73 antibody, in combination with atezolizumab in patients with advanced cancer,” data were presented from 20 refractory cancer patients with advanced or metastatic solid tumors treated with the combination of uliledlimab and atezolizumab.
Key results included:
- Uliledlimab was safe and well-tolerated up to 20 mg/kg every three weeks (Q3W) and 15 mg/kg once weekly (QW) as a monotherapy and in combination therapy with atezolizumab 1200 mg Q3W. No dose limiting toxicity was observed and the maximum tolerated dose was not reached.
- Full saturation of circulating and cell-bound CD73 was achieved at doses ≥ 10 mg/kg.
- Linear PK profile was observed at the doses ≥10 mg/kg following a single dose and the PK profile of uliledlimab supports Q3W dosing.
- There was evidence of clinical activity (one complete response, two partial responses and three cases of stable disease) in both PD-(L)1 treatment naïve and refractory cancer patients, following treatment with uliledlimab and atezolizumab.
- Higher tumor CD73 and PD-L1 co-expression were found in responders compared to non-responders.
“Uliledlimab was safe and refractory solid tumor patients benefitted following treatment with uliledlimab and atezolizumab,” said
The poster is available on TRACON’s website at www.traconpharma.com.
