PURPOSE There is growing scientific interest in incorporating patient-reported outcomes (PROs) in early phase dose-finding oncology trials (DFOTs) to assess tolerability, inform dose selection, and guide later stage trial design. However, research indicates that PRO objectives in DFOTs are often unclear. The Incorporating Patient-Reported Outcomes in Dose-Finding Trials-Research Objectives Recommendations (OPTIMISE-ROR) project was established to support trialists to effectively incorporate PROs into DFOTs. METHODS Using the Enhancing Quality and Transparency of Health Research (EQUATOR) Network's methodological framework, guideline development included the following: (1) a methodological review of published DFOTs incorporating PROs; (2) candidate item generation, refined through expert consultation; (3) a two-round international multistakeholder Delphi survey (N = 109 in Round 1 [October 2024]; N = 96 in Round 2 [December 2024]); and (4) an independently chaired virtual consensus meeting (N = 31; January 2025) where multidisciplinary, international experts reviewed and voted to finalize items for inclusion. RESULTS Consensus was reached on six recommendations emphasizing three core PRO tolerability concepts: overall side effect impact, symptomatic adverse events, and overall health-related quality of life. The integration of PROs to inform final dose recommendations in dose escalation and optimization trials should be considered, regardless of trial design. The recommendations highlight the importance of PRO data analysis over time and across dose levels, defining PRO research objectives as descriptive or statistically powered, and assessing PRO-related end points to guide end point selection for subsequent studies. CONCLUSION This foundational guidance outlines key PRO research objectives in DFOTs. By facilitating the systematic integration of PROs, this guidance supports the utilization of patient-centered evidence for the tolerability and efficacy assessment of therapies to inform dose escalation, optimization, and regulatory evaluation—ultimately contributing to the development of safer, more effective therapies.

Introduction Approximately 20% of patients (pts) with classical Hodgkin lymphoma (cHL) are age ≥ 60 years (yrs) at diagnosis (dx). Standard anthracycline-based therapies (ABTx) have historically shown lower efficacy and greater toxicity in this older population compared with younger pts, especially for unfit or frail pts. However, prior analyses have pre-dated the use of brentuximab vedotin (BV) and other novel targeted agents in the front-line setting and there remains no clearly defined or unified standard of care for this pt population. Studies in older lymphoma pts have also defined specific categories of pt fitness that may potentially guide therapy, although continued validation of these definitions in cHL are needed. We performed a large, multicenter retrospective study to identify current practice patterns in the US in older untreated cHL pts with specific attention to pt fitness using established definitions and to outcomes with ABTx versus non-ABTx. Methods Following IRB approval at each site, detailed pathologic and clinical data, including geriatric assessments (GAs) for the latter, were collected across 10 US academic medical centers. Eligible pts included: cHL dx on or after 1/1/2010, age ≥ 60 yrs at dx, and no preceding hematologic malignancy. Subjects with inadequate clinicopathologic and outcomes data or with dx other than cHL were excluded. A multivariable Cox proportional hazards model was developed to study the association of PFS and OS with various factors of interest, and survival rates were estimated by Kaplan-Meier using SPSS. Associations were considered significant for two-sided P values ≤ 0.05. Results Among 254 eligible older cHL pts with newly diagnosed disease, clinical features included: median age 67 yrs (range 60-90+), 54% male, 64% stage III/IV, 46% B symptoms, and 86.1% ECOG PS 0-1. 68.9% had nodular sclerosis, 18.9% mixed cellularity, and 12.2% other subtypes; EBV was detectable by IHC or peripheral blood in 39.3% of evaluable cases (n=98). In terms of geriatric measures, 31 pts (12.2%) had loss of at least one ADL; 40 (15.8%) had a geriatric syndrome; and 16 (6.3%) had both. Of note, only one pt underwent a comprehensive GA prior to treatment. Using established fitness definitions in lymphoma (Tucci et al, 2015), pts were classified as "Fit" (n=129; 50.8%), "Unfit" (n=8; 3.2%), or "Frail" (n=112 (44.1%); 5 (2%) were unclassifiable due to incomplete data (Table 1). Front-line regimens included ABVD (n=145; 57.1%), AVD (n=33; 13.0%), and CHOP (n=18; 7.1%). 6 pts (2.4%) received BV monotherapy; 21 (8.3%) received BV with AVD, the latter either concurrently (N=11) or sequentially (n=10). 11 pts did not receive systemic tx, of whom 9 received radiation alone; 58 pts received radiation with systemic tx. ABVD recipients received an average of 7.4 doses of bleomycin (range 1-14) and 18.4% (n=26) had pulmonary toxicity. In addition, 56.7% (n=130) of pts experienced at least one tx-related toxicity, which was similar across all fitness groups (Table 1). 15.1% (n=38) of pts stopped tx due to toxicity, which was noted more often in "frail" pts though it was relatively uncommon. 11 pts (4.3%) experienced treatment-related mortality (TRM). Compared with pts receiving non-ABTx, ABTx was associated with significantly improved PFS (HR 0.391, P=0.008) and OS (HR 0.195, P=0.0004). ECOG PS >1 was associated with inferior PFS (HR=1.96, P=0.017) and OS (HR=3.09, P=0.002). Pts defined as "frail" had no apparent difference in PFS compared with fit pts (Figure 1A;P=0.169), although decreased OS was seen (Figure 1B; P=0.01). Discussion To the best of our knowledge, these data represent one of the largest analyses of older cHL pts in the modern era. Our real-world analysis shows that in those who are able to receive them, anthracyclines provide meaningful survival benefit in this older cHL patient population and can be well-tolerated for many pts. The impact of dose intensity and backbone regimen are not yet known. In addition, current definitions of "fitness" incompletely identified pts at risk for poor outcomes or greater toxicity. Further studies are planned to better delineate fitness in this population.
