What side effects are associated with this type of intervention?

The most common side effects of 5-Fluorouracil when used for treating Basal Cell Carcinoma include local skin reactions such as redness, irritation, burning sensation, and inflammation at the application site. Prolonged use can lead to more severe skin reactions like ulceration and scarring. Calcipotriene, when used in combination, can cause similar local skin reactions, including itching, dryness, and erythema. Systemic side effects are rare due to the topical application of these treatments.

What prior FDA approvals exist?

5-Fluorouracil (5-FU) cream is FDA-approved for the treatment of superficial basal cell carcinoma (sBCC). It works by inhibiting DNA synthesis in cancer cells, leading to cell death. The combination of 5-Fluorouracil with Calcipotriene, which modulates cell differentiation and proliferation, is being studied for its potential to treat low-risk skin cancers, including sBCC. This combination has shown promise in clearing pre-cancerous lesions and preventing future skin cancers, offering a potentially shorter treatment course compared to 5-FU alone.

What other types of research exist?

Promising novel alternatives to 5-Fluorouracil and Calcipotriene Cream for Basal Cell Carcinoma patients include: 1) PAC-14028 cream, a TRPV1 antagonist, which has shown safety and efficacy in preclinical studies without increasing the risk of tumorigenesis. 2) Peldesine (BCX-34) cream, a purine nucleoside phosphorylase inhibitor, which is being evaluated for its efficacy in treating cutaneous T-cell lymphoma and may have potential applications in BCC. These alternatives are in various stages of research and may offer new therapeutic options for BCC patients by 2024.

5-Fluorouracil + Calcipotriene Cream for Skin Cancer

Q: What is the mechanism of action of this treatment?

5-Fluorouracil (5-FU) works by inhibiting DNA synthesis in cancer cells, leading to cell death, which is particularly effective in rapidly dividing cells like those in Basal Cell Carcinoma (BCC). Calcipotriene, a synthetic vitamin D derivative, modulates cell differentiation and proliferation, normalizing skin cell growth and enhancing the effectiveness of 5-FU. These mechanisms are crucial for BCC patients as they target cancerous cells specifically, aiming to minimize damage to healthy tissue.

Summary

This trial compares a standard cancer-killing cream with a new, potentially more effective cream. It targets patients with less aggressive skin cancers. The new cream might work better by combining two ingredients to kill cancer cells and prevent new ones from forming.

Who is the study for?

This trial is for English-speaking adults with low-risk skin cancers (sBCC or SCCis) on certain body parts, who haven't had treatment yet and aren't good candidates for surgery. They must be willing to follow the study plan and attend follow-ups. Women of childbearing age need a negative pregnancy test before starting and must use birth control during the study.

What is being tested?

The trial compares two creams: one with just 5-fluorouracil, an FDA-approved treatment, against a mix of 5-fluorouracil and calcipotriene. The goal is to see if the combo cream can clear cancer in a shorter time (7-14 days). Participants will be checked over three years to see if their skin cancer has been treated successfully.

What are the potential side effects?

Possible side effects include skin irritation, redness, burning sensation where the cream is applied, increased sensitivity to sunlight leading to sunburns more easily than usual, changes in skin color at the application site, itching or rash.
