Introduction: Patients with cognitive impairments, who may be unable to engage in traditional psychotherapies, may require support through non-cognitive interventions. This review synthesizes the existing literature to assess the evidence base for these interventions and to propose future directions for research. Methods: A comprehensive literature search was conducted across seven electronic databases on October 17, 2024. Eligible studies assessed psychological, emotional, social, or spiritual outcomes. Results: Seventy-three studies were included, conducted across 18 countries. Music therapy and art therapy had the strongest empirical support, with consistent effects on distress, emotional expression, social and spiritual connectedness, and finding meaning. Other approaches, including movement therapy, spiritual interventions, and pet therapy, showed promising but preliminary results. Aromatherapy and massage therapy yielded mixed findings, while energy-based methods lacked robust evidence. Most studies had a high risk of bias, primarily due to confounding. Few interventions were conducted with patients with cognitive impairments, despite their potential relevance. Conclusion: A variety of interventions compatible with cognitive impairment show promise in palliative care settings. However, existing empirical support is constrained by bias and a lack of research in cognitively-impaired populations.

370 Background: The Phase 1 portion of a Phase 1/2 trial of Necuparanib (“Necu”) combined with nab-paclitaxel (nabP) + gemcitabine (gem) in patients with metastatic pancreatic cancer (ClinicalTrials.gov Identifier NCT01621243) showed acceptable safety and tolerability and encouraging signals of activity and established a dose for the randomized, placebo (PBO)-controlled Phase 2 portion. Methods: In Phase 2, patients received daily s.c. injections of either 5 mg/kg Necu daily or PBO, combined with i.v. 125 mg/m2 nabP and 1000 mg/m2 gem (Days 1, 8, 15 of each 28-day cycle). The primary endpoint was overall survival (OS); other endpoints included progression-free survival (PFS), response rates, safety, and CA19.9 levels. An interim futility analysis was conducted in July 2016 once 57 deaths (50% of the target number of 114 events required for trial completion) had occurred. Results: The analysis was conducted on data from 120 randomized patients (62 Necu, 58 PBO). The Z-score for futility was -0.42 (prespecified boundary of -0.148 was crossed as actual score was lower). Median OS was Necu = 10.71 and PBO = 9.99 months; hazard ratio (HR) = 1.12 (favoring PBO); OS curves were intertwined. PFS was Necu = 5.52 and PBO = 6.93 months; HR = 0.97. RECIST response rates were comparable between arms: complete response, Necu = 0%, PBO = 3%; partial response, Necu = 26%, PBO = 26%; stable disease, Necu = 31%, PBO = 34%; disease control rate, Necu = 56%, PBO = 64%. The most common Grade 3+ adverse events (AEs) were neutropenia (Necu = 33%, PBO = 33%), thrombocytopenia (Necu = 27%, PBO = 5%), and anemia (Necu = 22%, PBO = 11%). There were lower rate of serious AEs with Necu (48%) vs. PBO (60%). Modest increases in APTT, AST, and ALT were noted following Necu relative to PBO. 23% of Necu and 5% of PBO patients were IgG positive with an anti-heparin/PF4 antibody titer of ≥ 0.4 at any time. There were no treatment differences for decreases in CA19.9. Conclusions: No new safety signals were observed and the toxicity profile was considered manageable; however, Necu in combination with nabP and gem did not show a sufficient level of efficacy in metastatic pancreatic cancer to warrant continued enrollment.
