Assessing the risk-benefit profile of ramucirumab in patients with advanced solid tumors: A meta-analysis of randomized controlled trials.

ABSTRACT: Background:Ramucirumab is a widely used cancer drug having gained six regulatory approvals in various advanced solid tumors. Thus, assessing the risk-benefit profile of such a commonly used drug across multiple tumor types is necessary to inform clinical and reimbursement decisions. To objectively assess the risks and benefits of ramucirumab in patients with advanced solid tumors, we performed a systematic review and meta-analysis of published randomized controlled trials (RCTs). Methods:A systematic search of PubMed, the Cochrane Library, Google Scholar and conference abstracts for all RCTs of ramucirumab in patients with advanced solid cancer was conducted according to the PRISMA guidelines. Data on treatment-related serious adverse events (SAEs), fatal adverse events (FAEs), primary endpoint, gains in median overall survival (OS), progression-free survival (PFS) with their hazard ratios (HR) and 95% confidence intervals (CIs) and quality of life (QOL) were extracted from each RCT. Summary relative risks (RR) with 95% CI for SAEs and FAEs were calculated by pooling data across the RCTs using random-effects model. Treatment benefit was evaluated descriptively in terms of median and HR with 95% CI of OS and PFS gains as well as improvements in QOL. ESMO-Magnitude of Clinical Benefit Scale (MCBS), a validated tool, was used to objectively quantify clinical benefit of ramucirumab in approved settings. Findings:Ten RCTs met our inclusion criteria. Compared with the control arm, the use of ramucirumab was associated with a significantly increased risk of developing SAE (RR 1.13, 95% CI 1.05-1.21, incidence 37.5% v 33.5%). The increase in risk of FAE (RR 1.41, 95% CI 0.96-2.07, incidence 1.8% v 1.3%) was not statistically significant. Using the ESMO MCBS tool, clinical benefit with ramucirumab was not substantial in any indication, five of six approvals scoring a "negligible benefit" score of 1 or 2. QOL was either not reported (30%) or not improved (70%) in these RCTs. Interpretation:In this meta-analysis of RCTs, use of ramucirumab in patients with advanced cancer was associated with increased risk of treatment related serious and possibly fatal adverse events but the magnitude of clinical benefit from ramucirumab was mostly negligible with no trial reporting an improvement in QOL. These relative risks and benefits should be considered in clinical and regulatory decision making. Funding:None.

Project description:ImportanceUse of next-generation sequencing (NGS) to identify clinically actionable genomic targets has been incorporated into routine clinical practice in the management of advanced solid tumors; however, the clinical utility of this testing remains uncertain.ObjectiveTo determine which patients derived the greatest degree of clinical benefit from NGS profiling.Design, setting, and participantsPatients in this cohort study underwent fresh tumor biopsy and blood sample collection for genomic profiling of paired tumor and normal DNA (whole-exome or targeted-exome capture with analysis of 1700 genes) and tumor transcriptome (RNA) sequencing. Somatic and germline genomic alterations were annotated and classified according to degree of clinical actionability. Results were returned to treating oncologists. Data were collected from May 1, 2011, to February 28, 2018, and analyzed from May 1, 2011, to April 30, 2020.Main outcomes and measuresPatients' subsequent therapy and treatment response were extracted from the medical record to determine clinical benefit rate from NGS-directed therapy at 6 months and exceptional responses lasting 12 months or longer.ResultsDuring the study period, NGS was attempted on tumors from 1138 patients and was successful in 1015 (89.2%) (MET1000 cohort) (538 men [53.0%]; mean [SD] age, 57.7 [13.3] years). Potentially clinically actionable genomic alterations were discovered in 817 patients (80.5%). Of these, 132 patients (16.2%) received sequencing-directed therapy, and 49 had clinical benefit (37.1%). Exceptional responses were observed in 26 patients (19.7% of treated patients). Pathogenic germline variants (PGVs) were identified in 160 patients (15.8% of cohort), including 49 PGVs (4.8% of cohort) with therapeutic relevance. For 55 patients with carcinoma of unknown primary origin, NGS identified the primary site in 28 (50.9%), and sequencing-directed therapy in 13 patients resulted in clinical benefit in 7 instances (53.8%), including 5 exceptional responses.Conclusions and relevanceThe high rate of therapeutically relevant PGVs identified across diverse cancer types supports a recommendation for directed germline testing in all patients with advanced cancer. The high frequency of therapeutically relevant somatic and germline findings in patients with carcinoma of unknown primary origin and other rare cancers supports the use of comprehensive NGS profiling as a component of standard of care for these disease entities.

Project description:BackgroundAntibodies targeting the programmed death-ligand 1 (PD-L1)/programmed cell death protein 1 (PD-1) checkpoint may cause adverse events (AEs) that are linked to the mechanism of action of this therapeutic class and unique from those observed with conventional chemotherapy.MethodsPatients with advanced solid tumors who were enrolled in the phase 1 JAVELIN Solid Tumor (1650 patients) and phase 2 JAVELIN Merkel 200 (88 patients) trials received avelumab, a human anti-PD-L1 IgG1 antibody at a dose of 10 mg/kg every 2 weeks. Treatment-related AEs (TRAEs) were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0). In post hoc analyses, immune-related AEs (irAEs) were identified via an expanded AE list and medical review, and infusion-related reactions (IRRs) occurring ≤2 days after infusion and symptoms occurring ≤1 day after infusion and resolving ≤2 days after onset were identified based on prespecified Medical Dictionary for Regulatory Activities (MedDRA) terms.ResultsOf the 1738 patients analyzed, grade ≥3 TRAEs occurred in 177 (10.2%); the most common were fatigue (17 patients; 1.0%) and IRR (10 patients; 0.6%). TRAEs led to discontinuation in 107 patients (6.2%) and death in 4 patients (0.2%). Grade ≥3 irAEs occurred in 39 patients (2.2%) and led to discontinuation in 34 patients (2.0%). IRRs or related symptoms occurred in 439 patients (25.3%; grade 3 in 0.5% [9 patients] and grade 4 in 0.2% [3 patients]). An IRR occurred at the time of first infusion in 79.5% of 439 patients who had an IRR, within the first 4 doses in 98.6% of 439 patients who had an IRR, and led to discontinuation in 35 patients (2.0%).ConclusionsAvelumab generally was found to be well tolerated and to have a manageable safety profile. A minority of patients experienced grade ≥3 TRAEs or irAEs, and discontinuation was uncommon. IRRs occurred mainly at the time of first infusion, and repeated events were infrequent.

Project description:Definitive management of locoregionally advanced solid tumors presents a major challenge and often consists of a combination of surgical, radiotherapeutic and systemic therapy approaches. Upfront surgical treatment with or without adjuvant radiotherapy carries the risks of significant morbidities and potential complications that could be lasting. In addition, these patients continue to have a high risk of local or distant disease relapse despite the use of standard adjuvant therapy. Preoperative neoadjuvant systemic therapy has the potential to significantly improve clinical outcomes, particularly in this era of expanding immunotherapeutic agents that have transformed the care of patients with metastatic/unresectable malignancies. Tremendous progress has been made with neoadjuvant immunotherapy in the treatment of several locoregionally advanced resectable solid tumors leading to ongoing phase 3 trials and change in clinical practice. The promise of neoadjuvant immunotherapy has been supported by the high pathologic tumor response rates in early trials as well as the durability of these responses making cure a more achievable potential outcome compared with other forms of systemic therapy. Furthermore, neoadjuvant studies allow the assessment of radiologic and pathological responses and the access to biospecimens before and during systemic therapy. Pathological responses may guide future treatment decisions, and biospecimens allow the conduct of mechanistic and biomarker studies that may guide future drug development. On behalf of the National Cancer Institute Early Drug Development Neoadjuvant Immunotherapy Working Group, this article summarizes the current state of neoadjuvant immunotherapy of solid tumors focusing primarily on locoregionally advanced melanoma, gynecologic malignancies, gastrointestinal malignancies, non-small cell lung cancer and head and neck cancer including recent advances and our expert recommendations related to future neoadjuvant trial designs and associated clinical and translational research questions.
