What is the purpose of this trial?

This trial tests whether combining two treatments, axitinib (a targeted therapy) and ipilimumab (an immunotherapy), can effectively treat advanced melanoma, a serious skin cancer. Researchers focus on cases where the cancer cannot be surgically removed and has not responded well to previous treatments, such as anti-PD-1 therapies. Suitable participants have advanced melanoma, excluding uveal melanoma (which affects the eye), and have not found success with other treatments. Participants should also have controlled blood pressure and no recent major health issues, such as severe bleeding or heart problems. As a Phase 2 trial, the research measures how well the treatment works in an initial, smaller group of people.

Do I have to stop taking my current medications for the trial?

The trial does not specify if you must stop taking your current medications, but you cannot use drugs or foods that strongly affect certain liver enzymes (CYP3A4/5) within 10 days before starting the trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that axitinib and ipilimumab have been used together in other studies to treat advanced melanoma, enhancing understanding of the combination's safety. Axitinib, when combined with treatments like nivolumab, has proven effective for advanced cases, with a focus on safety. Some patients experienced side effects, but these were manageable, indicating that axitinib is generally well-tolerated.

Ipilimumab has also been studied independently for advanced melanoma, showing positive results for survival, with many patients finding its side effects acceptable.

While strong safety information exists for both axitinib and ipilimumab individually, their combination is still under careful study to ensure safety for patients with advanced melanoma. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Axitinib and Ipilimumab for advanced melanoma because it offers a unique approach by combining a tyrosine kinase inhibitor with an immune checkpoint inhibitor. While standard treatments often involve other immune checkpoint inhibitors like pembrolizumab or nivolumab, this combination explores a novel synergy. Axitinib inhibits VEGF receptors to reduce tumor blood supply, potentially enhancing Ipilimumab's ability to activate the immune system against the cancer. This dual mechanism could improve treatment efficacy and provide a promising alternative for patients who may not respond to existing therapies.

What evidence suggests that axitinib and ipilimumab could be effective for advanced melanoma?

Research shows that using axitinib and ipilimumab together might be promising for treating advanced melanoma. Earlier studies with similar treatments have shown benefits, with 21.4% to 48% of patients experiencing a reduction or disappearance of their cancer. This suggests that these drugs could help shrink or control melanoma tumors in some patients. Additionally, axitinib has worked well with other cancer treatments, showing positive results in advanced cancer cases. These findings offer hope that axitinib and ipilimumab together might be effective for advanced melanoma. ^{1 2 4 6 7}

Published Research Related to This Trial

Ipilimumab (Yervoy) is the first new therapy approved for melanoma in over a decade, functioning as an antibody that blocks CTLA-4, which enhances the immune response against tumors, leading to durable tumor regression and improved overall survival in patients with advanced melanoma.

The clinical development of ipilimumab revealed its unique side effects profile and the long-lasting nature of its therapeutic responses, paving the way for future combination therapies with other checkpoint inhibitors currently being tested.

Immunomodulatory therapy for melanoma: ipilimumab and beyond. Callahan, MK., Postow, MA., Wolchok, JD.[2021]

Nivolumab is shown to be the most cost-effective treatment option for advanced melanoma patients in England, with incremental cost-effectiveness ratios of £24,483 for BRAF mutation-negative and £17,362 for mutation-positive patients.

The analysis utilized a Markov state-transition model based on patient-level data from clinical trials, indicating that nivolumab provides long-term survival benefits while being economically favorable compared to other treatments.

In a phase Ib study involving 31 patients with advanced melanoma, the combination of ipilimumab and peginterferon alfa-2b showed a maximum tolerated dose of ipilimumab at 3 mg/kg and peginterferon at 2 μg/kg/week, with a 40% overall response rate.

The treatment had a manageable safety profile, with 45.2% of patients experiencing grade 3 drug-related adverse events, but no severe (grade 4/5) adverse events, indicating that this combination therapy could be a promising option for further investigation.

Nivolumab combined with ipilimumab demonstrated significantly better overall survival compared to BRAF + MEK inhibitors, with hazard ratios indicating a 36% to 44% reduction in the risk of death after 12 months.

While nivolumab + ipilimumab had improved survival outcomes, it also resulted in a higher rate of grade 3/4 adverse events (54.1%) compared to dabrafenib + trametinib (31.6%) and similar rates to vemurafenib + cobimetinib (59.5%).

The combination of nivolumab and ipilimumab has achieved over 50% 5-year overall survival rates in patients with metastatic melanoma, although this combination is associated with high toxicity.

Current research is exploring new combinations of immune checkpoint inhibitors with other treatments, such as BRAF/MEK inhibitors and oncolytic viruses, aiming to improve long-term survival, especially in patients with poor prognosis.

Ipilimumab showed a best overall response rate (BORR) of 5.8% and a disease control rate (DCR) of 27% in patients with advanced melanoma, indicating some level of efficacy in this challenging population.

The treatment resulted in promising long-term survival rates, with 1- and 2-year survival rates of 47.2% and 32.8%, respectively, and a median overall survival of 10.2 months, while adverse events were primarily immune-related but manageable.

Ipilimumab, an anti-CTLA-4 antibody, has been shown to improve survival in patients with unresectable or metastatic melanoma, with a standard dosing of 3 mg/kg every 3 weeks for a total of 4 doses.

While ipilimumab can cause immune-related adverse events in 15% of patients, most are mild and manageable; however, high-grade events can be serious and require careful monitoring and treatment with corticosteroids.

Ipilimumab has shown a positive impact on overall survival in patients with stage IV melanoma, with long-term follow-up indicating its effectiveness compared to conventional treatments.

While 84.8% of patients experience drug-related adverse events, most are mild to moderate; however, severe reactions can occur, necessitating careful monitoring and management, especially when combined with other therapies like vemurafenib.

In a study of 56 patients with metastatic melanoma who had severe immune-related adverse events (AEs) from ipilimumab, 36% experienced at least one immune-related AE after receiving anti-PD-1 therapy, indicating a notable risk of recurrence but also a manageable safety profile.

Despite the risk of AEs, anti-PD-1 therapy showed a 43% overall response rate and a median overall survival of 21 months, suggesting it may offer improved outcomes for patients previously affected by severe toxic effects from ipilimumab.

Combining nivolumab and ipilimumab shows improved effectiveness in treating metastatic melanoma compared to using either drug alone, based on a retrospective analysis of approximately 7700 patients.

The combination therapy presents a safety profile that includes immune-related adverse events from both drugs, indicating that while the combination is effective, it also carries a heightened risk of toxicity that needs further investigation.
