7552 Background: Axi-cel is approved in the US for the treatment of adult patients with relapsed or refractory LBCL after 2 or more lines of systemic therapy. Post-market long term follow up study of commercial Axi-cel recipients using the Center for International Blood and Marrow Transplant Research was recently completed. Methods: From October 2017 to August 2020, 1,500 Axi-cel recipients from 79 centers were enrolled. Of these, 1001 patients with at least 6 months of follow-up were included in this analysis. Outcomes include complete and overall responses rates (CR and ORR), duration of response (DOR), progression-free and overall survival (PFS and OS), cytokine release syndrome (CRS) (Lee D 2014 and American Society for Transplantation and Cellular Therapy [ASTCT]), immune effector cell associated neurotoxicity syndrome (ICANS), hematologic recovery and subsequent neoplasm (SN). Subgroup analysis by sensitivity to therapy, defined as responsive to the last line of therapy prior to Axi-cel. Median follow-up was 12 months (range, 6-28 months). Results: The median age overall was 62 years, 37% were ≥ 65 years, 83% with Eastern Cooperative Oncology Group (ECOG) performance score 0-1, 28% with transformed lymphoma, 14% with high grade lymphoma, 29% with prior autologous transplant, and 66% with chemotherapy-resistant disease prior to Axi-cel. The median time from diagnosis to Axi-cel infusion was 15 months. Best ORR was 70% (CR 53%). Landmark analysis of patients in CR at 6 months post Axi-cel demonstrates a low number of subsequent progression/death events. With respect to outcomes for chemotherapy-sensitive disease versus resistant disease, the ORR, CR, 12-month PFS and OS were 78% vs. 66%, 60% vs. 48%, 55% (95% CI, 48-62%) vs. 40% (95% CI, 37-44%), and 70% (95% CI, 63-76%) vs. 54% (95% CI, 50-58%), respectively. CRS of any grade was reported in 83% of patients. Incidence of Grades ≥ 3 CRS was 10% according to Lee et al 2014, and 13% according to ASTCT Consensus Grading. Median time to any grade CRS was 4 days (range, 1-28 days), and 93% of CRS cases resolved with a median duration of 7 days (range, 1-121 days). ICANS were reported in 576 (57%) patients, grade >3 was 26%. The median time to onset of ICANS was 7 days (range, 1-82 days), and 86% resolved with a median duration of 9 days (range, 1 to 115 days). Twenty-nine patients (2.9%) reported SN: hematologic (N = 17), solid tumors (N = 12). Conclusions: This is the largest report on Axi-cel in the real-world setting and demonstrates consistent efficacy outcomes and further characterizes safety outcomes. Patients in CR at 6 months have sustained disease control with low number of relapse events. Although patients with therapy-sensitive disease experience better outcomes than patients with therapy-resistant, the overall outcomes on both groups of patients are favorable.

2016 Background: Among the primary aims of new therapies for glioblastoma (GBM) are the reduction of morbidity and restoration or preservation of quality of life (QoL). Selinexor (SEL) is a first-in class, oral, selective inhibitor of nuclear export which blocks exportin 1 (XPO1), forcing the nuclear retention and reactivation of tumor suppressor proteins, ultimately causing cell death in cancer cells. SEL is approved for the treatment of previously treated multiple myeloma and DLBCL. XPORT-GBM-029 (NCT04421378) is a phase 1 dose finding study followed by an open-label randomized phase 2, 3-arm trial to evaluate SEL in combination with standard therapies for newly diagnosed and recurrent GBM: Arm A (ndGBM, uMGMT) – radiation +/- SEL; Arm B (ndGBM, mMGMT) – radiation and temozolomide +/- SEL; Arm C (rGBM) – lomustine +/- SEL at first relapse. We look to identify sensitive, reliable, and clinically meaningful digital assessments of the functional status of ndGBM and rGBM patients via a patient-centric approach. Methods: XPORT-GBM-029 incorporates standard clinical and imaging evaluations of GBM progression with novel digital tools that objectively measure motor and cognitive function. The study is conducted at 50 sites globally with the aim of enrolling 350 patients with newly diagnosed and recurrent GBM. Following discussions with KOLs and patient advocacy partners at EndbrainCancer, we surveyed GBM patients and their caregivers to identify disease manifestations critical to patients’ QoL. The survey revealed four key areas impacting patients’ QoL that can be affected by GBM therapies and can be objectively monitored: cognitive function, lateralization, fatigue, and sleep. In this trial we use objective measurements to evaluate SEL’s effects on GBM patients’ QoL. Patients wear inertial sensors to measure their activity and sleep and complete a cognitive battery at baseline and before each MRI. Results: Associations between objective digital measures of activity, gait, fatigue, sleep, and cognition will be examined with respect to clinical assessments including physical examinations, modified Response Assessment in Neuro-Oncology (mRANO), Neurologic Assessment in Neuro-Oncology (NANO), Karnofsky Performance Score (KPS) and Patient Reported Outcome (PRO) QoL questionnaires. Descriptive summary statistics and plots are employed in exploratory data analysis, and other advanced data mining methods may also be considered. Conclusions: XPORT-GBM-029 trial is probably the first large, prospective, longitudinal study in GBM patients employing digital markers and may provide useful information regarding the utility of wearable and mobile devices for measuring functional outcomes in clinical trials.

2000 Background: Craniopharyngiomas, a rare brain tumor along the pituitary-hypothalamic axis, can cause significant clinical sequelae. Surgery and radiation, the only effective treatments, can cause significant morbidity. Genetic analysis of craniopharyngiomas revealed that 95% of papillary craniopharyngiomas (PCP) have BRAF V600E mutations (Brastianos et al. Nature Genetics 2014). We evaluated the efficacy of BRAF/MEK inhibition in patients (pts) with previously untreated PCP. Methods: Eligible pts without prior radiation whose PCP screened positively for BRAF mutations were treated with oral vemurafenib/cobimetinib in 28-day cycles. The primary endpoint of response rate (RR) based on centrally determined volumetric data was evaluated in 16 pts, where a partial response was defined as >20% decrease in volume. This single arm, Simon two-stage phase 2 trial had 89% power to detect a true RR of at least 30% (vs. the null RR 5%; alpha=0.04). In this design, 3 or more observed volumetric responses in 16 evaluable pts would be considered promising activity. Results: In the 16 pts evaluated, 56% were female, and the median age was 49.5 years. Median follow-up was 22 months (95% CI: 16-26.5) and median number of treatment cycles was 8. Three patients progressed after therapy was discontinued and none have died. Based on volumetric response criteria, 14 of 15 pts with volumetric data available for central review had response to therapy (93%; 95% CI: 68% to 99.8%). Of 16 patients evaluable based on local review, 15 had response to therapy (93.75%; 95% CI: 70% to 99.8%). The median tumor reduction was -83% (range: -52% to -99%). The one nonresponder received 2 days of treatment before coming off therapy due to toxicity. Median progression-free survival was not reached. Grade 3 toxicities at least possibly related to treatment occurred in 12 pts (rash in 6 pts). Grade 4 toxicities were observed in two pts: hyperglycemia (n=1) and increased CPK (n=1). Three pts discontinued treatment for adverse events. Conclusions: Vemurafenib/cobimetinib resulted in an objective response in all pts who received 1 or more cycles of therapy. Our study indicates that BRAF/MEK inhibitors could be a powerful tool in the treatment of previously untreated PCP and warrants further evaluation in larger studies. A second arm of this study is enrolling pts with progressive PCP after prior radiotherapy.

Abstract Diagnosis of interstitial lung disease (ILD) requires a multidisciplinary discussion approach that includes clinicians, radiologists, and pathologists. Surgical lung biopsy (SLB) is currently the recommended standard in obtaining pathologic specimens for patients with ILD requiring a tissue diagnosis. The increased diagnostic confidence and accuracy provided by microscopic pathology assessment of SLB specimens must be balanced with the associated risks in patients with ILD. This document was developed by the SLB Working Group of the Pulmonary Fibrosis Foundation, composed of a multidisciplinary group of ILD physicians, including pulmonologists, radiologists, pathologists, and thoracic surgeons. In this document, we present an up-to-date literature review of the indications, contraindications, risks, and alternatives to SLB in the diagnosis of fibrotic ILD; outline an integrated approach to the decision-making around SLB in the diagnosis of fibrotic ILD; and provide practical information to maximize the yield and safety of SLB.

Introduction: The risk of major atherosclerotic CV events increases with age, as do comorbidities, polypharmacy, and greater vulnerability to adverse drug reactions/events, posing challenges in the treatment of dyslipidemia. Three Phase III placebo-controlled trials evaluated the efficacy and safety of inclisiran according to age. Objective: To assess the efficacy and safety of inclisiran in patients across age categories. Methods: Patients were categorized according to age: <65 years (not old), ≥65 and <75 years (old), or ≥75 years (very old). The co-primary endpoints were percentage change in LDL-C from baseline to Day 510 and time-adjusted percentage change from baseline after Day 90 up to Day 540. Efficacy and safety parameters were assessed over 18 months. Results: Of a total 3660 patients, 1737 [47.5%] were not old, 1431 [39.1%] were old, and 492 [13.4%] were very old. At baseline, the prevalence of comorbidities increased with age (not old, old, very old): stage 3 CKD (8.4%, 19.9%, 31.2%), hypertension (72.9%, 85.2%, 88.1%) and diabetes mellitus (32.2%, 40.0%, 38.0%), respectively. The placebo-corrected percentage change in LDL-C with inclisiran was similar across all ages: from baseline to Day 510 [–51.3% (not old), –49.9% (old), –51.0% (very old); P <0.0001 for all] and time-adjusted from baseline to Day 90 up to Day 540 [–49.6% (not old), –51.5% (old), –50.8% (very old); P <0.0001 for all]. Overall AE and SAE rates increased with age and were similar between both treatment arms in all groups, except for injection-site reactions that were higher with inclisiran vs placebo across all ages, and were more frequent in not old patients. CK levels >5x ULN were more frequently elevated in the not old category (Table). Conclusion: Inclisiran lowered LDL-C similarly across all ages with an acceptable safety profile. Inclisiran added to maximally tolerated statin therapy could be a safe option for older patients with ASCVD who need more intensive lipid-lowering treatment.

Abstract Background: Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare, autosomal dominant disorder driven by mutations in ACVR1 that render it responsive to Activin A. FOP is characterized by progressive heterotopic ossification (HO) and distressing inflammatory events called “flare-ups.” Flare-ups can precede new HO; however, limited prospective data exists on this phenomenon. Garetosmab (GAR), an investigational human monoclonal antibody against Activin A, blocks formation of new HO in FOP. Methods: This is a post-hoc analysis of LUMINA-1 (NCT03188666) a phase 2, randomized, double-blind, placebo-controlled study, which evaluated the safety and efficacy of GAR (10 mg/kg/week IV) versus placebo (PBO) in adult patients with FOP over 28 weeks. Patient-reported flare-ups were collected via a patient diary and severity level was reported as mild, moderate or severe. Clinician-reported flare-ups were collected as adverse events in the trial. HO lesions were imaged by 18F-NaF positron emission tomography (PET) and whole-body low-dose X-ray computed tomography (CT). Results: There was a two-fold higher proportion of patients who reported one or more flare-ups on PBO 17/24 (71%) compared with GAR 7/20 (35%). Clinicians reported a four-fold higher proportion of patients experiencing one or more flare-ups on PBO 10/24 (42%) compared with GAR 2/20 (10%). Overall rates of flare-up events were two-fold higher on PBO vs. GAR (1.4 vs. 0.65 events/patient/28 weeks) for patient-reported events and eight-fold higher on PBO vs. GAR by clinician report (0.83 vs. 0.10 events/patient/28 weeks). Most flare-ups occurred on the extremities and back; pain was the most commonly reported symptom. Patient-reported flare-ups on PBO were more frequently reported as severe (29.4%) compared with GAR (7.7%). Among subjects with at least 12 weeks of follow-up from start of patient-reported flare-up, development of new HO near the site was 5/27 (18.5%) on PBO and (0%) on GAR. Of all new HO lesions, 41% on PBO and 0% on GAR occurred with spatial and temporal relation to flare-up. Conclusions: Approximately two-thirds of patients on PBO reported flare-ups over 28 weeks. GAR was associated with reductions in frequency and severity of flare-ups. Fewer than 20% of patient-reported flare-ups were associated with new HO, indicating frequent discordance of these phenomena, and compatible with previous reports. GAR’s ability to reduce patient- and clinician-reported flare-ups, as well as new HO lesions may provide an important therapeutic option.
