Choosing PD-1 Inhibitors in Oncology Setting, Left or Right?-Lessons From Value Assessment With ASCO-VF and ESMO-MCBS.

Influx of innovative therapies and dramatic rise in prices have been prompting value-driven decision-making. Both the American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) have independently proposed value assessment frameworks. To comprehensively examine the value of nivolumab and pembrolizumab by two value assessment frameworks with a cohort of published randomized controlled trials and offer insight into the association between these two frameworks. Trials were identified with a cutoff date of Nov 30th, 2019. Receiver operating characteristic curves were generated to establish the predictive value of ASCO-VF score to meet ESMO-MCBS grade and discriminate the agreement of these two value assessment tools. Spearman correlation was used to assess the association between monthly cost and ASCO-VF score/ESMO-MCBS grade. 19 randomized controlled trials were eligible. seven (36.8%) trials were of treatment included nivolumab while 12 (63.2%) pembrolizumab. 8 (42.1%) of the trials were of treatments for non-small-cell lung cancer, 5 (26.3%) for melanoma, 2 (10.5%) were for head and neck squamous cell carcinoma, 2 (10.5%) for gastric or gastro-oesophageal junction cancer and 1 (5.3%) for urothelial cancer and renal-cell carcinoma respectively. ASCO scores ranged from 7 to 94.7 with median 40.90. 11 (57.9%) trials met the ESMO criteria for meaningful value achieved. Of 14 trials not meeting the ASCO cutoff score, only 8 did not meet the meaningful ESMO criteria. Agreement between these two frameworks thresholds was only fair ( = 0.412, ＜0.05). A negative correlation was noted between increment monthly cost and value assessment results. There is only fair correlation between ASCO and ESMO value assessment frameworks. Not all treatment with nivolumab and pembrolizumab meet valuable thresholds.
