Triamcinolone Acetonide Injections in Primary Cutaneous Lymphoma Plaques With a Novel Needle-free Drug-delivery System.

Triamcinolone Acetonide Injections in Primary Cutaneous Lymphoma Plaques With a Novel Needle-free Drug-delivery System.

A study to compare pain differences between using MedJet needle-free drug-delivery system with standard of care treatment for cutaneous T-cell lymphomas and cutaneous B-cell lymphomas in participants.

Participants will undergo treatments on two morphologically and anatomically matched target lesions, preferably on opposing sides of the body.

The first plaque will be treated using standard of care topical bexarotene or nitrogen mustard for participants with CTCL (cutaneous T-cell lymphomas) or intralesional TAC (triamcinolone acetonide) using a syringe/needle with participants with CBCL (cutaneous B-cell lymphomas).

The second plaque will be treated using a needle-free injector system. After the treatment, the participants will be followed for another three visits over the course of 4 months to see how the treated areas responded.

In order to account for 20% dropout, 11 patients per group (a needle free and a traditional treatment group in CBCL patients and the same two groups in CTCL patients) will be recruited.

Inclusion Criteria:

1. > 18 years of age

   • Symmetrically located on contralateral body site OR
   • Within the same body site but separated by ≥ 1 cm
   • Both plaques must be similar in size as much as possible

4. Able to give informed consent under IRB approval procedures

Exclusion Criteria:

1. Known allergy or hypersensitivity to triamcinolone acetonide
