Patient and Staff Experiences of Embedding Electronic Patient Reported Outcome Measures for Distress Screening and Quality of Life Assessment, Into Routine Melanoma Care: A Mixed-Methods Study.

Objective: Patient reported outcome measures (PROMs) are commonly collected in melanoma research. However, they are not used to guide immediate clinical care in Australia. This study explored the views and experiences of patients with Stage III melanoma and clinic staff during implementation of an electronic Patient-Reported Outcome Measures in melanoma (ePROMs-MEL) pilot to assess distress and quality of life.

Three-Year Overall Survival With Nivolumab Plus Relatlimab in Advanced Melanoma From RELATIVITY-047.

Nivolumab plus relatlimab demonstrated a statistically significant improvement in progression-free survival (PFS), along with a clinically meaningful, but not statistically significant improvement in overall survival (OS) and a numerically higher objective response rate (ORR) compared with nivolumab in the RELATIVITY-047 trial (ClinicalTrials.gov identifier: NCT03470922). We report updated descriptive efficacy and safety results from RELATIVITY-047 with a median follow-up of 33.

Outcomes following long-term disease control with immune checkpoint inhibitors in patients with advanced melanoma.

Immune checkpoint inhibitors (ICI) can achieve durable responses in patients with advanced melanoma, and results from clinical trials suggest cure may be possible for a subset of patients. Despite clinical trial data, little is known about the risk, character, and clinical outcome of late recurrences after ICI. This study aimed to explore the disease outcomes and survival in a cohort of patients with long-term responses to ICI.

Treatment sequence with tebentafusp and immune checkpoint inhibitors in patients with metastatic uveal melanoma and metastatic GNA11/GNAQ mutant melanocytic tumors.

Background: Metastatic uveal melanoma (mUM) is rare. Immune checkpoint inhibitors (ICIs) have shown modest efficacy in mUM. Tebentafusp prolonged overall survival (OS) in a phase 3 study.

Long-term outcomes among patients who respond within the first year to nivolumab plus ipilimumab or nivolumab monotherapy: A pooled analysis in 935 patients.

Purpose: To investigate the predictive value of RECIST response within 3, 6, or 12 months on long-term survival, and explore differences between nivolumab+ipilimumab and nivolumab monotherapy, we analyzed pooled 5-year data of 935 responder and non-responder patients at various time points after treatment initiation in CheckMate 069, 066, and 067 studies.

Patients And Methods: Treatment-naive advanced melanoma patients received nivolumab+ipilimumab or nivolumab monotherapy. To decrease immortal time bias, 3-, 6-, or 12-month overall survival (OS) and progression-free survival (PFS) landmark analyses were performed.

Impact of personalized response-directed surgery and adjuvant therapy on survival after neoadjuvant immunotherapy in stage III melanoma: Comparison of 3-year data from PRADO and OpACIN-neo.

Background: Pathologic response following neoadjuvant immune checkpoint blockade (ICB) in stage III melanoma serves as a surrogate marker for long-term outcomes. This may support more personalized, response-directed treatment strategies.

Methods: The OpACIN-neo and PRADO trials were phase 2 studies evaluating neoadjuvant treatment with ipilimumab and nivolumab in stage III melanoma.

Pembrolizumab versus ipilimumab for advanced melanoma: 10-year follow-up of the phase III KEYNOTE-006 study.

Background: Pembrolizumab significantly improved overall survival (OS) versus ipilimumab for unresectable advanced melanoma in KEYNOTE-006 (NCT01866319); 10-year follow-up data are presented.

Patients And Methods: Patients with unresectable stage III or IV melanoma were randomly assigned (1:1:1) to pembrolizumab 10 mg/kg i.v.

Efficacy of anti PD-1 therapy in children and adolescent melanoma patients (MELCAYA study).

Background: Data on the efficacy and safety of anti PD-1 antibodies in children and adolescents (CA) with melanoma are lacking. The aim of this study was to determine outcomes of CA melanoma patients receiving anti PD-1 antibodies.

Methods: Melanoma patients ≤18 years treated with anti PD-1 were retrospectively retrieved from 15 academic centers.

Single-cell RNA sequencing reveals melanoma cell state-dependent heterogeneity of response to MAPK inhibitors.

Background: Melanoma is a heterogeneous cancer influenced by the plasticity of melanoma cells and their dynamic adaptations to microenvironmental cues. Melanoma cells transition between well-defined transcriptional cell states that impact treatment response and resistance.

Methods: In this study, we applied single-cell RNA sequencing to interrogate the molecular features of immunotherapy-naive and immunotherapy-resistant melanoma tumours in response to ex vivo BRAF/MEK inhibitor treatment.

A targetable type III immune response with increase of IL-17A expressing CD4 T cells is associated with immunotherapy-induced toxicity in melanoma.

Immune checkpoint inhibitors are standard-of-care for the treatment of advanced melanoma, but their use is limited by immune-related adverse events. Proteomic analyses and multiplex cytokine and chemokine assays from serum at baseline and at the adverse event onset indicated aberrant T cell activity with differential expression of type I and III immune signatures. This was in line with the finding of an increase in the proportion of CD4 T cells with IL-17A expression at the adverse event onset in the peripheral blood using flow cytometry.

Circulating tumour DNA dynamics predict recurrence in stage III melanoma patients receiving neoadjuvant immunotherapy.

Background: Neoadjuvant therapy improves recurrence-free survival (RFS) in resectable stage III cutaneous melanoma. However, accurately predicting individual recurrence risk remains a significant challenge. We investigated circulating tumour DNA (ctDNA) as a biomarker for recurrence in measurable stage IIIB/C melanoma patients undergoing neoadjuvant immunotherapy.

Outcomes With Postrecurrence Systemic Therapy Following Adjuvant Checkpoint Inhibitor Treatment for Resected Melanoma in CheckMate 238.

Purpose: In phase III CheckMate 238, adjuvant nivolumab significantly improved recurrence-free survival compared with ipilimumab in patients with resected stage IIIB-C/IV melanoma without a significant difference in overall survival (OS). Here, we investigate progression-free survival (PFS) and OS after postrecurrence systemic therapy.

Patients And Methods: Patients 15 years or older with resected stage IIIB-C/IV melanoma were stratified by stage and tumor PD-L1 status and randomly assigned to receive nivolumab 3 mg/kg every 2 weeks, or ipilimumab 10 mg/kg every 3 weeks for four doses and then every 12 weeks for 1 year or until disease recurrence, unacceptable toxicity, or withdrawal of consent.

Alcohol does not impact chronic hepatitis C treatment outcomes but increases risk for progressive liver disease: Findings from a prospective multicentre Australian study (OPERA-C).

Introduction: Alcohol use is common in patients with chronic hepatitis C virus (HCV) infection. We examined the impact of alcohol use on direct-acting antiviral (DAA) therapy outcome and the clinical course of liver disease and 2-year survival for patients receiving HCV DAA therapy.

Methods: Adults (n = 2624) recruited from 26 Australian hospital liver clinics during 2016-2021 were followed up for 2 years.

Baseline biomarkers of efficacy and on-treatment immune-profile changes associated with bempegaldesleukin plus nivolumab.

In PIVOT IO 001 (NCT03635983), the combination of the investigational interleukin-2 agonist bempegaldesleukin (BEMPEG) with nivolumab (NIVO) had no added clinical benefit over NIVO monotherapy in unresectable/metastatic melanoma. Pre-defined baseline and on-treatment changes in selected biomarkers were analyzed to explore the potential mechanisms underlying the clinical observations. In each treatment arm, higher baseline tumor mutational burden or immune infiltration/inflammation was associated with improved efficacy compared with lower levels.

Single-cell spatial multiomics reveals tumor microenvironment vulnerabilities in cancer resistance to immunotherapy.

Heterogeneous resistance to immunotherapy remains a major challenge in cancer treatment, often leading to disease progression and death. Using CITE-seq and matched 40-plex PhenoCycler tissue imaging, we performed longitudinal multimodal single-cell analysis of tumors from metastatic melanoma patients with innate resistance, acquired resistance, or response to immunotherapy. We established the multimodal integration toolkit to align transcriptomic features, cellular epitopes, and spatial information to provide deeper insights into the tumors.

Exploiting temporal aspects of cancer immunotherapy.

Many mechanisms underlying an effective immunotherapy-induced antitumour response are transient and critically time dependent. This is equally true for several immunological events in the tumour microenvironment induced by other cancer treatments. Immune checkpoint therapy (ICT) has proven to be very effective in the treatment of some cancers, but unfortunately, with many cancer types, most patients do not experience a benefit.

Open-label, phase II study of talimogene laherparepvec plus pembrolizumab for the treatment of advanced melanoma that progressed on prior anti-PD-1 therapy: MASTERKEY-115.

Background: Treatment options for immunotherapy-refractory melanoma are an unmet need. The MASTERKEY-115 phase II, open-label, multicenter trial evaluated talimogene laherparepvec (T-VEC) plus pembrolizumab in advanced melanoma that progressed on prior programmed cell death protein-1 (PD-1) inhibitors.

Methods: Cohorts 1 and 2 comprised patients (unresectable/metastatic melanoma) who had primary or acquired resistance, respectively, and disease progression within 12 weeks of their last anti-PD-1 dose.
