Article Synopsis
  • CheckMate 204 study found that the combination of nivolumab and ipilimumab resulted in high intracranial objective response rates (icORRs) for patients with melanoma brain metastases (MBMs), prompting a need for standardized response criteria.
  • Different assessment criteria (like mRECIST and volumetric measurements) showed higher icORRs and stronger correlations with progression-free survival (icPFS) and overall survival (OS) compared to RANO-BM and RECIST.
  • The analysis suggests that mRECIST and volumetric criteria are reliable scales for future MBM trials, and response can be effectively measured even in patients with small lesions (<10 mm).

Introduction: Prior studies suggest lymphopenia following radiation therapy may impact toxicity and cancer control. Chronic radiation-related lymphopenia (RRL) has been noted in prostate cancer patients treated with conventionally fractionated pelvic radiation therapy. The impact of utilizing hypofractionated high integral dose therapies such as stereotactic body radiation therapy (SBRT) on RRL is less well characterized.

  • Nivolumab (NIVO) combined with ipilimumab (IPI) shows better long-term overall survival (OS) in patients with unresectable/metastatic melanoma than NIVO alone, based on pooled data from major trials.
  • Patients treated with the combination therapy had a median follow-up OS of 45.0 months, with 6-year survival rates at 52%, compared to 41% for NIVO monotherapy after a median follow-up of 35.8 months.
  • Clinical factors affecting survival include elevated lactate dehydrogenase (LDH) levels, age over 65 with the combination therapy, and presence of liver metastases with NIVO alone.

  • Immunotherapy, like the combination of nivolumab and ipilimumab (NIVO+IPI), can lead to prolonged disease control and treatment-free survival (TFS) for cancer patients, even after stopping treatment, which is not accounted for by standard survival measures.
  • A study analyzed data from 1,096 advanced renal cell carcinoma patients to estimate TFS, comparing those treated with NIVO+IPI against sunitinib (SUN), focusing on both survival time and treatment-related adverse events (TRAEs).
  • Results showed that 48% of patients on NIVO+IPI were alive after 5 years, with a significant difference in mean TFS compared to SUN, particularly in favorable-risk patients, highlighting the importance of considering

Regulatory approval of immune checkpoint inhibitors (ICIs) was based on results of large, randomized clinical trials, resulting in limited outcomes data in patient cohorts typically underrepresented in such trials. The objective of this study was to evaluate the efficacy and safety of ICIs in these unique patient cohorts. This is a multicenter, retrospective analysis of real-world data at six academic and community clinics in the United States from 1 January 2011 to 1 April 2018.

Background: As part of a partitioned survival analysis, treatment-free survival (TFS) can characterize the overall survival time patients spend between the cessation of immunotherapy and the start of subsequent therapy; both with and without toxicity. Significant TFS was reported for the nivolumab/ipilimumab arms of the CheckMate 067 and 214 trials for patients with advanced melanoma or renal cell carcinoma (aRCC), respectively, where immunotherapy was often halted for toxicity rather than a predefined treatment endpoint. We therefore sought to assess TFS in the HCRN GU16-260 trial, which was designed to reduce toxicity and cap immunotherapy duration.

Article Synopsis
  • The study aimed to assess treatment-free survival (TFS) in patients with advanced renal cell carcinoma (aRCC) undergoing immune-oncology (IO) and VEGF tyrosine kinase inhibitor (TKI) combination therapies compared to TKI alone.
  • The analysis pooled data from three randomized trials involving over 2,300 patients, evaluating outcomes like overall survival (OS), TFS with and without toxicity across a 30-month period.
  • Results indicated that both treatment groups experienced similar TFS durations, with slightly different rates of being free from severe toxicity, suggesting the treatment protocols influenced the observed outcomes.

Background: Tivozanib is an oral vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI) with efficacy in advanced renal cell carcinoma (RCC). Long-term exploratory analyses from the TIVO-3 trial in relapsed/refractory (R/R) RCC including patients (26%) with prior immuno-oncology (IO) therapy are reported.

Methods: Patients with R/R advanced RCC that progressed with 2 or 3 prior systemic therapies (≥1 VEGFR TKI) were randomized to tivozanib 1.

Purpose: Programmed cell death protein 1 (PD-1) expression on CD8+TIM-3-LAG-3- tumor-infiltrating cells predicts positive response to PD-1 blockade in metastatic clear-cell renal cell carcinoma (mccRCC). Because inhibition of PD-1 signaling in regulatory T cells (Treg) augments their immunosuppressive function, we hypothesized that PD-1 expression on tumor-infiltrating Tregs would predict resistance to PD-1 inhibitors.

Experimental Design: PD-1+ Tregs were phenotyped using multiparametric immunofluorescence in ccRCC tissues from the CheckMate-025 trial (nivolumab: n = 91; everolimus: n = 90).

Melanoma brain metastases (MBM) are clinically challenging to treat and exhibit variable responses to immune checkpoint therapies. Prior research suggests that MBM exhibit poor tumor immune responses and are enriched in oxidative phosphorylation. Here, we report results from a multi-omic analysis of a large, real-world melanoma cohort.

Background: Nivolumab plus ipilimumab has demonstrated improved survival for treatment-naïve advanced clear cell renal cell carcinoma (RCC). A series of clinical trials evaluated the effect of salvage nivolumab plus ipilimumab in patients without an objective response to nivolumab. Given the size and heterogeneity of these studies, we performed a pooled analysis to better inform the activity of nivolumab plus ipilimumab after nivolumab.

With multiple PD-(L)1 inhibitors approved across dozens of indications by the US Food and Drug Administration, the number of patients exposed to these agents in adjuvant, first-line metastatic, second-line metastatic, and refractory treatment settings is increasing rapidly. Although some patients will experience durable benefit, many have either no clinical response or see their disease progress following an initial response to therapy. There is a significant need to identify therapeutic approaches to overcome resistance and confer clinical benefits for these patients.

Immune-related adverse events (irAEs) associated with immune checkpoint inhibitor (ICI) therapy may vary substantially in their clinical presentation, including natural history, outcomes to treatment, and patterns. The application of clinical guidelines for irAE management can be challenging for practitioners due to a lack of common or consistently applied terminology. Furthermore, given the growing body of clinical experience and published data on irAEs, there is a greater appreciation for the heterogeneous natural histories, responses to treatment, and patterns of these toxicities, which is not currently reflected in irAE guidelines.
