Abstract Background Upadacitinib (UPA) is an oral Janus kinase inhibitor approved for the treatment of moderately to severely active Crohn’s disease (CD).1 The U-ENDURE (NCT03345823) maintenance study and long-term extension (LTE) evaluate the long-term efficacy and safety of UPA maintenance therapy. Here, we report the results of the U-ENDURE LTE. Methods Patients (pts) completing the U-ENDURE 52-week (wk) maintenance study were eligible to participate in the LTE and continue their previously assigned treatment (placebo [PBO], UPA 15 mg [UPA15] once daily [QD], or UPA 30 mg [UPA30] QD; blinded until the last pt completed maintenance wk52). Clinical response, clinical remission, endoscopic response, endoscopic remission, as well as high-sensitivity C-reactive protein (hs-CRP) and faecal calprotectin (FCP) were evaluated as-observed up to wk48 of the LTE among pts (PBO [N = 89], UPA15 [N = 107], UPA30 [N = 173]); excluding pts who received open-label UPA30 rescue therapy. Safety was assessed in all pts (PBO [N = 223], UPA15 [N = 221], UPA30 [N = 229]) from wk0 of the maintenance study up to LTE wk204 (cut-off date: 01 Aug 2023). Results At LTE wk0, the SF/APS clinical remission rates were 73.0%, 78.3%, and 80.3% for PBO, UPA15, and UPA30, respectively (Figure 1A). Similar rates were reported at LTE wk0 for CDAI clinical remission (PBO 75.3%, UPA15 81.3%, UPA30 80.9%; Figure 1B) and clinical response (CR-100: PBO 79.5%, UPA15 84.9%, UPA30 84.4%). Rates of clinical remission were stable through wk48 of the LTE. Endoscopic response (PBO 32.9%, UPA15 59.6%, UPA30 66.5%) and remission rates (PBO 27.8%, UPA15 42.4%, UPA30 47.3%) at LTE wk0 were sustained through wk48 with UPA while decreased with PBO (Figure 1C-D). At LTE wk0, the mean [95% CI] change from induction BL in hs-CRP was 1.8 [–0.4, 4.1], –13.2 [–17.9, –8.6], and –12.8 [–16.8, –8.9] for PBO, UPA15, and UPA30, respectively; sustained through wk48. Similar results were observed with FCP (mean [95% CI] change from induction BL: PBO 126 [–103, 356], UPA15 –2946 [–4121, –1772], UPA30 –1871 [–2577, –1165]). Severe adverse events (AEs) and serious AEs were lower with UPA treatment compared with PBO (Table 1). The rates of most AEs of special interest were similar between UPA and PBO; however, numerically higher rates of herpes zoster, adjudicated gastrointestinal perforations, neutropenia, lymphopenia, creatine phosphokinase elevation, and hepatic disorders were reported in pts treated with UPA vs PBO (Table 1). Conclusion In pts completing wk48 of the LTE, sustained efficacy was observed in clinical and endoscopic endpoints with over 2 years of UPA treatment, while maintaining an overall positive safety profile in pts with CD.

748 Background: Ripretinib is a switch-control tyrosine kinase inhibitor approved for patients (pts) with gastrointestinal stromal tumor (GIST) who received prior treatment with 3 or more kinase inhibitors, including imatinib. Sunitinib is approved for advanced GIST after imatinib failure. In the second interim analysis of overall survival (OS) from the phase 3 INTRIGUE study, the OS event rate was 41% in the all-patient (AP) intent-to-treat (ITT) population, and OS was similar between treatment arms in both the KIT exon 11 ITT and AP ITT populations. Here, we present the final OS and updated safety from INTRIGUE. Methods: INTRIGUE (NCT03673501) is an open-label, phase 3 study of adults with advanced GIST who had disease progression on or intolerance to imatinib. Randomization was 1:1 to ripretinib 150 mg once daily (QD) or sunitinib 50 mg QD (4 weeks on/2 weeks off) and was stratified by KIT mutational status and imatinib intolerance. OS was a key secondary endpoint (the primary endpoint of progression-free survival was reported previously); final OS analysis was prespecified to occur with ≥200 and ≥145 events in the AP ITT and KIT exon 11 ITT populations, respectively. Data cutoff was March 15, 2023. Results: Of 453 pts, 444 received treatment; 40 remain on treatment (ripretinib, 28/223 [13%]; sunitinib, 12/221 [5%]). Treatment discontinuation was due to progressive disease (PD) by independent radiologic review (56%), PD by investigator (11%), clinical PD (6%), withdrawal of consent (6%), and adverse events (AEs; 5%). Fewer pts discontinued treatment due to AEs with ripretinib vs sunitinib (3% vs 6%). There were 211 OS events (47%) in the AP ITT population and 151 OS events (46%) in the KIT exon 11 ITT population. OS was similar with ripretinib vs sunitinib in the 2 ITT populations (Table). Fewer pts had grade 3/4 treatment-emergent AEs with ripretinib vs sunitinib (43% vs 67%). Dose interruptions and reductions were lower with ripretinib vs sunitinib. Median treatment duration for ripretinib vs sunitinib was 7.9 vs 6.5 months. Conclusions: In the finalOS analysis from the INTRIGUE study, OS was similar between treatment arms. The safety profile remained consistent and more favorable for ripretinib vs sunitinib in pts with advanced GIST previously treated with imatinib. Clinical trial information: NCT03673501 .

OBJECTIVE It is not clear whether there is an additive effect of social factors in keeping patients with cervical spondylotic myelopathy (CSM) from achieving both a minimum clinically important difference (MCID) in outcomes and satisfaction after surgery. The aim of this study was to explore the effect of multiple social factors on postoperative outcomes and satisfaction. METHODS This was a multiinstitutional, retrospective study of the prospective Quality Outcomes Database (QOD) CSM cohort, which included patients aged 18 years or older who were diagnosed with primary CSM and underwent operative management. Social factors included race (White vs non-White), education (high school or below vs above), employment (employed vs not), and insurance (private vs nonprivate). Patients were considered to have improved from surgery if the following criteria were met: 1) they reported a score of 1 or 2 on the North American Spine Society index, and 2) they met the MCID in patient-reported outcomes (i.e., visual analog scale [VAS] neck and arm pain, Neck Disability Index [NDI], and EuroQol-5D [EQ-5D]). RESULTS Of the 1141 patients included in the study, 205 (18.0%) had 0, 347 (30.4%) had 1, 334 (29.3%) had 2, and 255 (22.3%) had 3 social factors. The 24-month follow-up rate was > 80% for all patient-reported outcomes. After adjusting for all relevant covariates (p < 0.02), patients with 1 or more social factors were less likely to improve from surgery in all measured outcomes including VAS neck pain (OR 0.90, 95% CI 0.83–0.99) and arm pain (OR 0.88, 95% CI 0.80–0.96); NDI (OR 0.90, 95% CI 0.83–0.98); and EQ-5D (OR 0.90, 95% CI 0.83–0.97) (all p < 0.05) compared to those without any social factors. Patients with 2 social factors (outcomes: neck pain OR 0.86, arm pain OR 0.81, NDI OR 0.84, EQ-5D OR 0.81; all p < 0.05) or 3 social factors (outcomes: neck pain OR 0.84, arm pain OR 0.84, NDI OR 0.84, EQ-5D OR 0.84; all p < 0.05) were more likely to fare worse in all outcomes compared to those with only 1 social factor. CONCLUSIONS Compared to those without any social factors, patients who had at least 1 social factor were less likely to achieve MCID and feel satisfied after surgery. The effect of social factors is additive in that patients with a higher number of factors are less likely to improve compared to those with only 1 social factor.

OBJECTIVE Microvascular decompression (MVD) is a well-established and highly effective treatment option for hemifacial spasm (HFS). Lateral spread response (LSR) has been used as an intraoperative indicator of HFS resolution, with controversial reliability. The purpose of this study was to determine long-term outcomes of MVD for HFS and the role of LSR and other preoperative predictors. METHODS The authors conducted a cohort study of all patients treated with MVD for HFS at a single institution from January 1, 1998, to December 31, 2019. In addition to a retrospective chart review, all patients were contacted at the time of the study to provide informed consent and responded to a telephone survey to ascertain their current disease and medication status. Patients with at least 12 months of postoperative follow-up were included. Statistical testing included a Student t-test, Fisher’s exact test, logistic regression, and Cox proportional hazards analysis. RESULTS One hundred nineteen patients met study criteria; 41 (34%) had at least 10 years of clinical follow-up. HFS fully resolved in 93 (78%), symptoms subjectively improved in 11 (9%) and were unchanged in 15 (13%). Immediate postoperative HFS status did not correlate with long-term outcome (p = 0.13). Changes in LSR were not associated with outcome. Patients receiving neuromodulating agents had significantly longer preoperative duration of symptoms and were more likely to show persistent LSR intraoperatively. HFS recurrence was associated with younger age at the time of surgery but not with intraoperative LSR resolution. CONCLUSIONS This study demonstrated that MVD for HFS is highly effective for most patients. Neither intraoperative LSR change nor immediate postoperative status was predictive of long-term outcomes.

Background Sex‐specific risk management may improve outcomes in congenital long QT syndrome (LQTS). We recently developed a prediction score for cardiac events (CEs) and life‐threatening events (LTEs) in postadolescent women with LQTS. In the present study, we aimed to develop personalized risk estimates for the burden of CEs and LTEs in male adolescents with potassium channel‐mediated LQTS. Methods and Results The prognostic model was derived from the LQTS Registry headquartered in Rochester, NY, comprising 611 LQT1 or LQT2 male adolescents from age 10 through 20 years, using the following variables: genotype/mutation location, QTc‐specific thresholds, history of syncope, and β‐blocker therapy. Anderson‐Gill modeling was performed for the end point of CE burden (total number of syncope, aborted cardiac arrest, and appropriate defibrillator shocks). The applicability of the CE prediction model was tested for the end point of the first LTE (excluding syncope and adding sudden cardiac death) using Cox modeling. A total of 270 CEs occurred during follow‐up. The genotype–phenotype risk prediction model identified low‐, intermediate‐, and high‐risk groups, comprising 74%, 14%, and 12% of the study population, respectively. Compared with the low‐risk group, high‐risk male subjects experienced a pronounced 5.2‐fold increased risk of recurrent CEs ( P <0.001), whereas intermediate‐risk patients had a 2.1‐fold ( P =0.004) increased risk . At age 20 years, the low‐, intermediate‐, and high‐risk adolescent male patients had on average 0.3, 0.6, and 1.4 CEs per person, respectively. Corresponding 10‐year adjusted probabilities for a first LTE were 2%, 6%, and 8%. Conclusions Personalized genotype–phenotype risk estimates can be used to guide sex‐specific management in male adolescents with potassium channel‐mediated LQTS.

Background We aimed to identify patients with subphenotypes of postacute coronary syndrome (ACS) using repeated measurements of high‐sensitivity cardiac troponin T, N‐terminal pro‐B‐type natriuretic peptide, high‐sensitivity C‐reactive protein, and growth differentiation factor 15 in the year after the index admission, and to investigate their association with long‐term mortality risk. Methods and Results BIOMArCS (BIOMarker Study to Identify the Acute Risk of a Coronary Syndrome) was an observational study of patients with ACS, who underwent high‐frequency blood sampling for 1 year. Biomarkers were measured in a median of 16 repeated samples per individual. Cluster analysis was performed to identify biomarker‐based subphenotypes in 723 patients without a repeat ACS in the first year. Patients with a repeat ACS (N=36) were considered a separate cluster. Differences in all‐cause death were evaluated using accelerated failure time models (median follow‐up, 9.1 years; 141 deaths). Three biomarker‐based clusters were identified: cluster 1 showed low and stable biomarker concentrations, cluster 2 had elevated concentrations that subsequently decreased, and cluster 3 showed persistently elevated concentrations. The temporal biomarker patterns of patients in cluster 3 were similar to those with a repeat ACS during the first year. Clusters 1 and 2 had a similar and favorable long‐term mortality risk. Cluster 3 had the highest mortality risk. The adjusted survival time ratio was 0.64 (95% CI, 0.44–0.93; P =0.018) compared with cluster 1, and 0.71 (95% CI, 0.39–1.32; P =0.281) compared with patients with a repeat ACS. Conclusions Patients with subphenotypes of post‐ACS with different all‐cause mortality risks during long‐term follow‐up can be identified on the basis of repeatedly measured cardiovascular biomarkers. Patients with persistently elevated biomarkers have the worst outcomes, regardless of whether they experienced a repeat ACS in the first year.

Background: Multiligamentous knee injuries (MLKIs) are devastating injuries with concomitant injuries that complicate treatment and recovery. Short-term studies have shown satisfactory patient outcomes after surgical treatment; however, evaluations of long-term outcomes remain scarce. Purpose: To evaluate long-term outcomes after surgically reconstructed MLKIs and further investigate the relationship between patient age on clinical outcomes. Study Design: Case series; Level of evidence, 4. Methods: A total of 55 knees (age, 36 ± 11 years; 24% female subjects) who underwent surgical reconstruction for MLKI between 1992 and 2013 met the study inclusion criteria and were evaluated with postoperative patient-reported outcomes (PROs) including International Knee Documentation Committee (IKDC) score, Lysholm score, visual analog scale (VAS) for pain, Forgotten Joint Score, subjective improvement ratings and surgery satisfaction, and Tegner activity scores. PRO scores, revision, and conversion to arthroplasty were analyzed using descriptive statistics, linear regression, Wilcoxon rank-sum, and Fisher exact tests. Results: At final follow-up (mean, 15 ± 5 years; range, 10-31 years), 67% of the cohort reported subjective improvement in their knee, and 82% reported satisfaction with their surgery. Compared with preoperative scores, there were significant improvements in postoperative VAS pain at rest in the full cohort, age ≤30-year cohort, and age >30-year cohort (4 ± 1 vs 2 ± 2; 4 ± 1 vs 2 ± 3; 4 ± 1 vs 1 ± 2, respectively; P≤ .029 for all) but significant reductions in Tegner scores (6 ± 3 vs 4 ± 2; 7 ± 2 vs 5 ± 2; 5 ± 2 vs 3 ± 1; P≤ .003 for all). Younger patients had higher postoperative Tegner scores than older patients (5 ± 2 vs 3 ± 1, respectively; P = .003), but no other differences in PROs were observed based on age. At a mean 15-year follow-up, 3.6% of the cohort underwent revision ligament surgery and 10.9% required arthroplasty. Conclusion: The majority of the cohort reported modest subjective improvement and were satisfied with their surgery. Gradual but expected age-related decreases in Tegner scores were observed, and some patients demonstrated continued symptomatic and functional limitations, but mean PRO scores remained satisfactory. Revision surgery and conversion to arthroplasty were not commonly required.

The application of cryotherapy in the extraction of airway blood clots has gained increased precedence over Fogarty catheter and biopsy forceps. The cryoprobe, passed through a flexible bronchoscope, adheres and aids in the removal of foreign body through cryoadhesion within minutes. Besides blood clots, this method was found to be extremely efficient in removing different kinds of foreign bodies including food particles like peanuts, pills, and inspissated mucus.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical trial updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. In 2003, the Eastern Cooperative Oncology Group initiated a randomized phase III clinical trial (E4402) comparing two different rituximab dosing strategies for patients with previously untreated low–tumor burden follicular lymphoma. Rituximab-responsive patients (n = 299) were randomly assigned to either a retreatment rituximab (RR) strategy or a maintenance rituximab (MR) strategy. Each dosing strategy was continued until treatment failure. The primary end point of the study was time to treatment failure (TTF). In the original report, there was no difference in TTF between the two dosing strategies. Here, we report on the long-term outcomes for secondary end points of time to first cytotoxic therapy, duration of response, and overall survival (OS). At 7 years, 83% of MR patients had not required first chemotherapy compared with 63% of RR patients (hazard ratio, 2.37 [95% CI, 1.5 to 3.76]). At 7 years, 71% of MR remained in their first remission compared with 37% of RR patients. Despite the improved first remission length with MR, there was no difference in OS at 10 years (83% v 84%). With mature long-term data, we confirm that prolonged maintenance rituximab does not confer an OS advantage in low–tumor burden follicular lymphoma.
