VTX-2337 in Combination With Radiotherapy in Patients Low-Grade B-cell Lymphomas

September 23, 2019 updated by: Celgene

A Phase I/II Study of Intratumoral Injection of the Small Molecule TLR8 Agonist VTX-2337 in Combination With Local Radiation in Low-Grade B-cell Lymphomas

This study is to determine the safety and effectiveness of VTX-2337 (an investigational drug that stimulates the immune system) in combination with radiation therapy in treating patients with low-grade B-cell lymphoma. Patients will receive 2 low doses of radiotherapy, and 9 intratumoral injections of VTX-2337 over the course of 3 months.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
OTHER: VTX-2337 plus radiation
Drug: VTX-2337 plus radiotherapy
Radiation on Day 1. On Day 2, VTX-2337 3.0mg/m2 is administered intratumorally, followed by radiation. VTX-2337 3.0mg/m2 is then given weekly for 3 weeks in a 4 week cycle over 3 cycles.

Measure Description
Time Frame
Number of Participants Whose Tumors Responded to Treatment With Intratumoral Injection of VTX-2337 in Combination With Low-Dose Local Radiation.
Time Frame: Tumor assessment conducted at 12 weeks and every 3-6 months thereafter
Tumor response was assessed via CT scans of the chest, abdomen, pelvis or other medically appropriate imaging modality to evaluate all areas of disease. Cheson Criteria were used for calculation of response.
Tumor assessment conducted at 12 weeks and every 3-6 months thereafter
