Trial Summary

What is the purpose of this trial?

This trial tests a combination of light therapy and a drug called POTELIGEO for patients with early-stage skin cancer. The light therapy aims to improve skin conditions, while POTELIGEO helps the immune system target and destroy cancer cells.

Will I have to stop taking my current medications?

The trial requires a 14-day period without previous CTCL therapy before starting treatment. If you're on a stable dose of low-dose systemic corticosteroids or certain topical medications, you may continue them, but the doctor will try to reduce the dose if possible. Other medications, especially those affecting the immune system or causing photosensitivity, may need to be stopped.

What data supports the effectiveness of the drug mogamulizumab-kpkc for treating mycosis fungoides?

Research shows that mogamulizumab-kpkc significantly improves progression-free survival and overall response rates in patients with mycosis fungoides compared to another treatment, vorinostat. Additionally, combining mogamulizumab with phototherapy has shown greater antitumor activity in a mouse model, suggesting potential benefits for this combination in treating cutaneous T-cell lymphoma. ^{1 2 3 4 5}

Is the combination of Phototherapy and Mogamulizumab safe for treating Mycosis Fungoides?

Mogamulizumab has been shown to be generally safe in humans, but it can cause side effects like rash, fatigue, and infections. Serious reactions can occur, especially related to infections and skin issues, and it has specific warnings for use before certain transplants. ^{1 4 5 6 7}

How is the treatment of phototherapy combined with mogamulizumab unique for mycosis fungoides?

This treatment is unique because it combines phototherapy, which uses light to treat skin conditions, with mogamulizumab, a drug that targets specific receptors on cancer cells to enhance the immune system's ability to fight the disease. This combination aims to improve the effectiveness of treatment for advanced stages of mycosis fungoides, offering a novel approach compared to traditional therapies. ^{1 2 3 4 5}

I am fully active or can carry out light work.

I have been on a stable low dose of corticosteroid for at least 4 weeks.

Exclusion Criteria

I've had a severe allergic reaction to POTELIGEO.

I have not had major surgery or radiation therapy in the last 4 weeks.

I was diagnosed with cancer in the last 2 years, but it's not active or one of the exceptions listed.

Treatment Details

Interventions

• Mogamulizumab-Kpkc (Monoclonal Antibodies)
• Phototherapy (Procedure)

Trial Overview The PLIGHT study tests combining phototherapy with an immunotherapy drug called Mogamulizumab in patients with early-stage mycosis fungoides. It's an open-label pilot study where all participants receive both treatments concurrently at a single center.

Participant Groups

Group I: POTELIGEO & Phototherapy combination therapy Experimental Treatment 2 Interventions

POTELIGEO (mogamulizumab-kpkc) will be given according to FDA approved dose and scheduled for 8 cycles. After 2 cycles of POTELIGEO, all subjects will start phototherapy as combination therapy.

Mogamulizumab-Kpkc is already approved in Canada, Japan for the following indications:

Approved in Canada as Poteligeo for:

• Mycosis fungoides
• Sézary syndrome

Approved in Japan as Poteligeo for:

• Adult T-cell leukemia/lymphoma
• Cutaneous T-cell lymphoma

Findings from Research

Mogamulizumab shows promising efficacy for patients with advanced cutaneous T-cell lymphomas, with a median progression-free survival (PFS) of 22 months based on a study of 21 patients followed for an average of 11.6 months.

The safety profile of mogamulizumab is considered acceptable, with 20 patients experiencing adverse events, of which only 10 were severe (grade III-IV), and the median time to the first adverse event was 21 days.

Impact of Mogamulizumab in Real-Life Advanced Cutaneous T-Cell Lymphomas: A Multicentric Retrospective Cohort Study. Jouandet, M., Nakouri, I., Nadin, L., et al.[2022]

In a study of 122 patients with cutaneous T-cell lymphoma (CTCL), mogamulizumab demonstrated an overall response rate of 58.7%, with higher efficacy in Sézary syndrome (69.5%) compared to Mycosis Fungoides (46.0%).

Mogamulizumab was generally well-tolerated, with serious adverse reactions occurring in a small percentage of patients, including rash (8.1%) and infusion-related reactions (2.4%), indicating a favorable safety profile in real-world settings.
