What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study was to evaluate the efficacy and safety of pembrolizumab plus epacadostat compared to sunitinib or pazopanib in participants with locally advanced/metastatic renal cell carcinoma (mRCC) with a clear cell component who have not received prior systemic therapy for their mRCC.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does mention that you must not have received any prior systemic therapy for your kidney cancer. It's best to discuss your current medications with the trial team.

Is the combination of Pembrolizumab and Epacadostat safe for humans?

Pembrolizumab has been studied in various cancers and is generally considered safe, but it can cause side effects like fatigue, nausea, and immune-related issues such as inflammation of the lungs, liver, or thyroid. Rarely, it can lead to type 1 diabetes. There is no specific safety data available for the combination with Epacadostat in kidney cancer. ^{1 2 3 4 5}

What makes the drug combination of Pembrolizumab and Epacadostat unique for kidney cancer?

The combination of Pembrolizumab, an immune checkpoint inhibitor, and Epacadostat, an IDO inhibitor, is unique because it targets the immune system to fight kidney cancer, potentially offering a novel approach compared to traditional treatments that may not focus on immune modulation. ^{4 6 7 8 9}

What data supports the effectiveness of the drug combination of Pembrolizumab and Epacadostat for kidney cancer?

Research shows that the combination of Epacadostat and Pembrolizumab has shown promising activity in treating various advanced solid tumors, including renal cell carcinoma (a type of kidney cancer), by potentially enhancing the immune system's ability to fight cancer. ^{10 11 12 13 14}

Published Research Related to This Trial

In a trial involving 62 patients with advanced solid tumors, the combination of epacadostat (an IDO1 inhibitor) and pembrolizumab (a PD-1 inhibitor) was generally well tolerated, with no maximum tolerated dose reached and only 11% of patients discontinuing due to treatment-related adverse events.

The combination therapy showed promising antitumor activity, with 55% of melanoma patients and responses observed in other cancer types, indicating potential effectiveness across various advanced solid tumors.

In a phase 3 trial involving 706 patients with unresectable stage III or IV melanoma, the combination of epacadostat and pembrolizumab did not show any significant improvement in progression-free survival or overall survival compared to pembrolizumab alone.

The most common serious side effects were similar between the two groups, with no treatment-related deaths reported, indicating that the combination therapy was generally safe but ineffective in enhancing treatment outcomes.

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.

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.

Pembrolizumab, a PD-1 inhibitor used in cancer treatment, can lead to rare but serious immune-related adverse events, including type 1 diabetes mellitus, occurring in about 0.2% of cases.

A review of 42 cases revealed that patients may develop diabetic ketoacidosis during treatment, highlighting the need for blood glucose monitoring and awareness of this potential side effect among clinicians.

In a phase II study involving 110 patients with advanced clear cell renal cell carcinoma (ccRCC), pembrolizumab demonstrated a 36.4% objective response rate, indicating significant antitumor activity as a first-line treatment.

The treatment was generally well-tolerated, with 30% of patients experiencing grade 3-5 adverse events, primarily colitis and diarrhea, which aligns with safety profiles observed in other cancers.

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, an immune checkpoint inhibitor for non-small cell lung carcinoma, has been linked to adverse renal outcomes, including acute kidney injury.

In a reported case, a patient developed acute tubulointerstitial nephritis after starting pembrolizumab, and while renal function improved with long-term corticosteroid treatment after discontinuation of the drug, it only improved partially.

This study presents the first known case of a patient with metastatic melanoma who was successfully treated with pembrolizumab while undergoing hemodialysis, highlighting its potential efficacy in patients with end-stage renal disease.

Pembrolizumab, an FDA-approved monoclonal antibody for metastatic melanoma and non-small cell lung cancer, shows promise for use in patients with renal complications, although specific dosing guidelines for such patients are still lacking.

In a phase 3 trial with 861 patients suffering from advanced clear-cell renal-cell carcinoma, the combination of pembrolizumab and axitinib significantly improved overall survival (89.9% vs. 78.3% at 12 months) compared to sunitinib, with a hazard ratio for death of 0.53.

Patients receiving pembrolizumab plus axitinib also experienced longer progression-free survival (15.1 months vs. 11.1 months) and a higher objective response rate (59.3% vs. 35.7%), indicating that this combination therapy is more effective than sunitinib for this condition.
