Recurrent Primary Cutaneous T-Cell Non-Hodgkin Lymphoma Clinical Trial
Official title:
A Phase I/II Multicenter Clinical Trial of O6Benzylguanine and Topical Carmustine in the Treatment of Refractory Early-Stage (IA-IIA) Cutaneous T-Cell Lymphoma

This phase I/II trial studies the side effects and best dose of carmustine when given together with O6-benzylguanine and to see how well they work in treating patients with stage IA-IIA cutaneous T-cell lymphoma. Drugs used in chemotherapy, such as carmustine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. O6-benzylguanine may help carmustine work better by making cancer cells more sensitive to the drug. Giving O6-benzylguanine with carmustine may kill more cancer cells.

Primary | Overall Response Rate | Based on changes in modified SWAT assessment, patient responses will be classified as complete clinical response (CCR), partial response (PR), stable disease (SD), or progressive disease (PD). SWAT provides an accurate and reproducible assessment of cutaneous disease involvement based on body surface area of involvement and lesional thickness. CCR: No evidence of disease, 100% improvement for a duration of at least 4 weeks. PR: Greater than or equal to 50% decrease in SWAT score compared to baseline and improvement is maintained for at least 4 weeks. SD: Less than 50% decrease in SWAT score compared to baseline. PD: Increase of greater or equal to 25% of the SWAT score compared to baseline while the patient is actively taking the study drug |
