Summary

In this conversation, James Larkin and Sapna Patel discuss the findings of the Checkmate 204 study, which looked at the treatment of brain metastases from melanoma using nivolumab and ipilimumab. They highlight that the combination therapy showed efficacy in asymptomatic patients with brain metastases, with a 55% intracranial clinical benefit rate. They also discuss the importance of early detection and treatment of brain metastases, as well as the role of local therapies such as surgery and stereotactic radiotherapy. The conversation emphasizes the need to minimize the use of steroids and start systemic treatment as soon as possible.

Takeaways

The combination therapy of nivolumab and ipilimumab showed efficacy in asymptomatic patients with brain metastases from melanoma.
Early detection and treatment of brain metastases is crucial for improving outcomes.
Local therapies such as surgery and stereotactic radiotherapy can be used for symptomatic brain metastases.
Minimizing the use of steroids and starting systemic treatment as soon as possible is important.
The systemic standard of care for brain metastases from melanoma is ipinivo.

Sound Bites

"NIVO-IPI is active in the brain for asymptomatic patients."

"If you have an asymptomatic untreated brain met measuring at least 0.5 centimeters, there's activity with this combination."

"When I was learning how to treat this disease 20 years ago, having brain metastasis was basically a death sentence. Now we're talking about three-year data and it looks like the possibility of cure in some of these patients."

Ep 02: RELATIVITY-047

Summary

In this episode of Melanoma Matters, James Larkin and Sapna Patel discuss the RELATIVITY 047 trial, which evaluated the combination of nivolumab and relatlimab in frontline metastatic melanoma. They cover the trial design, response rates, overall survival, toxicity, and the role of PD-L1 expression in treatment decisions. They also explore the potential use of nivolumab and relatlimab in patients with brain metastases. While the combination showed a superior progression-free survival compared to nivolumab monotherapy, it did not demonstrate a significant overall survival benefit. The tolerability profile was better than ipilimumab and nivolumab combination therapy but had more side effects than anti-PD-1 monotherapy.

Takeaways

The RELATIVITY 047 trial evaluated the combination of nivolumab and relatlimab in frontline metastatic melanoma.

The combination showed a superior progression-free survival compared to nivolumab monotherapy.

There was no significant overall survival benefit observed in the trial.

The tolerability profile of nivolumab and relatlimab was better than ipilimumab and nivolumab combination therapy but had more side effects than anti-PD-1 monotherapy.

PD-L1 expression may play a role in treatment decisions, but its use as a biomarker is still debated.

The efficacy of nivolumab and relatlimab in patients with brain metastases is an area of interest.

Further follow-up and data analysis are needed to fully understand the long-term outcomes of the combination therapy.

Sound Bites

"Relativity 047 was a randomized phase three study for frontline metastatic melanoma using dual checkpoint inhibition."

"Relativity 047 is hitting some marks, but it's missing others. It has a PFS benefit but no OS benefit."

"The CheckMate 067 trial had a sicker population with higher LDH and declining performance status compared to RELA 047."

Ep 04: EORTC 18071

In this conversation, Sapna Patel and James Larkin discuss the EORTC 18071 study, which compared adjuvant ipilimumab to placebo in patients with stage III melanoma. They explore the use of adjuvant interferon in the past and the controversies surrounding its overall survival benefit. They also discuss the tolerability and side effects of ipilimumab, as well as the potential reasons for the survival benefit seen in the EORTC 18071 study. The conversation concludes with a summary of the study's findings.

Keywords

adjuvant therapy, ipilimumab, placebo, stage three melanoma, EORTC 18071 study, adjuvant interferon, overall survival benefit, tolerability, side effects, survival benefit

Takeaways

The EORTC 18071 study showed a significant overall survival benefit with adjuvant ipilimumab in patients with stage three melanoma.

The use of adjuvant interferon in the past was controversial, with a loss of overall survival benefit over time.

Ipilimumab has significant side effects and can impact patients' quality of life.

The survival benefit seen in the EORTC 18071 study may be due to the early use of CTLA-4 blockade in the immune sequence.

The subsequent use of PD-1 therapy as salvage treatment may explain the lack of overall survival benefit in other checkpoint inhibitor adjuvant trials.

"This was our only study that actually has overall survival benefit in the adjuvant setting using checkpoint inhibitor."

"The use of adjuvant interferon really dwindled when that OS benefit was lost."

"We would tell patients, you will know you're on treatment and you will walk around feeling like you have the flu."
