Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot receive other cancer treatments or certain medications like systemic corticosteroids within 14 days before joining the trial.

What data supports the effectiveness of the drug pembrolizumab for treating desmoplastic melanoma?

Pembrolizumab has shown to improve survival in patients with advanced melanoma and has been approved for treating advanced melanoma, indicating its effectiveness in similar types of skin cancer. ^{1 2 3 4 5}

Is pembrolizumab safe for humans?

Pembrolizumab, also known as Keytruda, has been shown to be generally safe in humans, with common side effects including fatigue, rash, itching, and diarrhea. Some less common side effects can affect the immune system, such as inflammation of the lungs (pneumonitis), liver (hepatitis), or thyroid gland (hypothyroidism or hyperthyroidism). ^{1 6 7 8 9}

How is the drug pembrolizumab unique in treating desmoplastic melanoma?

Pembrolizumab is unique because it is a monoclonal antibody that targets the PD-1 receptor on T cells, helping the immune system attack cancer cells more effectively. It has shown high response rates in melanoma with minimal side effects, making it a promising option compared to traditional treatments. ^{1 2 3 6 10}

What is the purpose of this trial?

This pilot phase II trial studies how well pembrolizumab works in treating patients with desmoplastic melanoma (DM) that can be removed by surgery (resectable) or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Treatment Details

Interventions

• Pembrolizumab

Trial Overview The trial is testing pembrolizumab's effectiveness on resectable (can be removed by surgery) and unresectable (cannot be removed by surgery) desmoplastic melanoma. Pembrolizumab is an immunotherapy drug designed to help the immune system fight cancer cells. The study includes imaging tests like CT scans and may involve biopsies and collecting tissue samples.

Participant Groups

Group I: Cohort B (pembrolizumab) Experimental Treatment 6 Interventions

Patients with unresectable disease receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 34 cycles in the absence of disease progression or toxicity. Patients undergo CT scan and may undergo PET and MRI throughout the study. Patients also undergo blood sample collection at screening and tumor biopsy throughout the study.

Group II: Cohort A (pembrolizumab, surgery) Experimental Treatment 7 Interventions

Patients receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 3 cycles. Patients with potentially resectable disease undergo surgery. Patients with tumor progression and unresectable disease may receive one additional cycle of pembrolizumab. Patients undergo CT scan and may undergo PET and MRI throughout the study. Patients also undergo blood sample collection at screening and tumor biopsy throughout the study.

Findings from Research

Pembrolizumab, a PD-1 inhibitor, has demonstrated clinical effectiveness in treating various solid tumors, particularly in patients with PD-L1-positive non-small-cell lung cancer and unresectable/metastatic melanoma.

Early-phase trials and ongoing studies are focused on further confirming the clinical benefits of pembrolizumab in thoracic malignancies, highlighting its potential as a significant treatment option in cancer therapy.

Pembrolizumab is a monoclonal antibody that effectively blocks the PD-1 receptor on T cells, enhancing their ability to attack cancer cells, particularly in melanoma patients.

In a Phase I study involving 411 patients, pembrolizumab demonstrated high durable response rates with minimal toxicity, indicating its potential as a safe and effective treatment option for melanoma.

Pembrolizumab joins the anti-PD-1 armamentarium in the treatment of melanoma. Hersey, P., Gowrishankar, K.[2017]

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.

In a study of 183 patients with advanced melanoma treated with pembrolizumab, several baseline factors such as active brain metastases, higher total metabolic tumor volume (TMTV), and lower absolute lymphocyte count (ALC) were linked to worse survival outcomes.

TMTV was identified as a more effective predictor of treatment futility compared to other markers like C-reactive protein (CRP) and lactate dehydrogenase (LDH), suggesting that patients with high TMTV may not benefit from pembrolizumab therapy.

Pembrolizumab, an anti-PD-1 antibody, has shown significant efficacy in treating advanced melanoma, demonstrating superior progression-free survival compared to chemotherapy in Phase II trials and improved overall survival in Phase III trials.

The treatment is generally well tolerated with a favorable safety profile, though common side effects include fatigue and rash, while less frequent but serious immune-related adverse events can occur.

Pembrolizumab (KEYTRUDA) was approved by the FDA for treating advanced melanoma, showing an overall response rate of 24% in a trial of 89 patients, with 86% of responses lasting at least 6 months.

While there are potential immune-mediated side effects, the benefits of prolonged tumor response durations were deemed to outweigh these risks, marking an improvement over existing treatments.
