Treatment of Cutaneous Metastases With Diphenylcyclopropenone (DPCP)

Completed · Phase 1

Conditions studied: Neoplasm Metastasis, Melanoma

In brief

Melanoma is a life-threatening cancer which poses a significant health burden, especially when metastatic or spreading to areas other than the original tumor growth. Although various treatment options are currently available for melanoma, melanomas that have metastasized widely to the skin pose a significant clinical challenge as the available therapies have limited effect. This study proposes the use of a topically applied compound named diphenylcyclopropenone (DPCP) which has been shown to be effective in treating melanoma patients whose diseases have spread widely throughout the skin. DPCP works by having a patient's own immune system, which is usually used to fight infections, attack cancerous cells. This compound has commonly been used to treat other conditions such as warts and hair loss throughout the world for many years and is known to cause limited side effects. Altering a patient's own immune system through topical treatments has also been shown to benefit patients with other cancers that have metastasized to skin such as breast cancer. In this study, the investigators will use DPCP to treat cutaneous metastases of various cancers including melanoma. Our overall intention is to get a better understanding of effective immune responses in the skin that may mediate metastatic cancer regression or cure.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• male or female at least 18 years of age, up to 99 years of age
• able to give verbal and written informed consent
• clinically diagnosed cancer with multiple cutaneous metastases that are able to be biopsied. The subject may or may not be on concomitant cancer treatments/have internal metastases.
• for women of childbearing potential (WOCBP) or in men whose partners may become pregnant, willingness to use an acceptable method of contraception to prevent pregnancy for the duration of the study (while receiving study medication and for one month following the last dose of study medication). Acceptable forms of contraception are listed in the informed consent form.
• must have a negative urine pregnancy test (for WOCBP)
• must be willing and able to have the therapy applied by the investigator, must be willing and able to self-apply the therapy, and must be willing and able to comply with study instructions and return for required clinic visits.
• clinically diagnosed melanoma with multiple cutaneous metastasis that are able to be biopsied. The subject will be on concurrent PD-1 checkpoint inhibitor therapy (standard nivolumab or pembrolizumab, not on another clinical trial) and may or may not have internal metastasis.

You may not qualify if…

• subjects taking any of the following systemic or topical therapies within 4 weeks of enrollment: corticosteroids, immunosuppressants, and/or any other medications that may affect the outcome of the study
• subjects who have active localized or systemic medical conditions that, in the opinion of the investigator, would preclude or make unsafe their participation in the study
• subjects with any underlying diseases or dermatological conditions of the affected areas that require the use of interfering topical or systemic therapy
• subjects who are nursing mothers, pregnant, or planning to become pregnant at anytime during the course of the study or within 30 days of study completion
• subjects who are unable to comply with study procedures, communicate effectively, cooperate with the investigator, or are unable to understand the study
• history, physical, social, or lab findings suggestive of any medical or psychological condition that would, in the opinion of the PI, make the candidate ineligible for the study
• HIV positive as determined by self-reported history and/or a HIV point-of-care test at screening
