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