Immunotherapy Dosing Strategies: Optimizing Efficacy and Managing Toxicity in Melanoma
Panelists discuss how the dose-response relationship is more pronounced with ipilimumab than with PD-1 inhibitors, explaining why toxicity increases with higher ipilimumab doses while efficacy may not proportionally improve with higher PD-1 inhibitor doses.

Dosing Considerations and Patient Selection
Key Discussion Points:
- Dose-response and dose-toxicity relationships differ between immunotherapy agents
- Clinical scenario-specific treatment selection balancing efficacy needs vs toxicity risks
- Patient characteristics influencing treatment selection for combination immunotherapy
Key Points for Physicians:
- Ipilimumab demonstrates a clear dose-response relationship with higher efficacy but increased toxicity at higher doses (10 mg/kg vs 3mg/kg)
- PD-1 inhibitors do not show similar dose-response relationships, with lower doses demonstrating similar efficacy with less toxicity
- For frail patients with low disease burden, consider PD-1 monotherapy or nivolumab/relatlimab; for patients with high disease burden or brain metastases, ipilimumab/nivolumab may be warranted despite toxicity risks
Notable Insights:
For patients with brain metastases but significant comorbidities or frailty, clinicians may consider nivolumab/relatlimab based on emerging data from studies like Bluebonnet showing intracranial efficacy.
Clinical Significance:
Treatment selection requires careful patient stratification, weighing disease characteristics against patient factors, with dosing decisions that optimize the efficacy-toxicity balance for each individual patient.
