Pembrolizumab Administered Via the Sofusa® DoseConnect™ in Patients With Relapsed/Refractory Cutaneous T-cell Lymphoma.

Phase 1
Recruiting
Conditions
Mycosis Fungoides
Interventions
Combination Product: Pembrolizumab administered using the Sofusa® DoseConnect™
Registration Number
NCT04118868
Lead Sponsor
Sorrento Therapeutics, Inc.
Brief Summary

In this pilot study, pembrolizumab will be administered via DoseConnect in patient with relapsed or refractory cutaneous T-cell lymphoma to assess through pharmacodynamic assessment in the tumor tissue to assess if lymphatic delivery of pembrolizumab using Sofusa DoseConnect is feasible.

Detailed Description

This is an open-label, single-center pilot study to investigate the pharmacodynamics, pharmacokinetics (PK), safety, and activity of pembrolizumab administered intra-lymphatically using the DoseConnect in participants with relapsed or refractory cutaneous T-cell lymphoma (CTCL).

All participants will receive the study intervention, pembrolizumab administered intralymphatically using the Sofusa DoseConnect device.
