Background: Menin, a protein involved in transcriptional regulation, plays a role in the genesis of multiple cancers. Preclinical data from BMF-219, an investigational, highly selective, oral small-molecule inhibitor of menin, show sustained potent abrogation of menin-dependent oncogenic signaling. BMF-219 is the first and only covalent menin inhibitor in clinical development and is being evaluated in multiple hematologic malignancies, solid tumors, and diabetes mellitus. COVALENT-101 (NCT05153330) is a Phase I dose-escalation and -expansion study of BMF-219 in R/R AL (Cohort 1), DLBCL (Cohort 2), MM (Cohort 3), and CLL (Cohort 4). Here we report preliminary safety, PK and anticancer activity data from Cohort 1 (AL). Methods: Doses of BMF-219 are escalated independently for each indication, initially in single-subject cohorts followed by a “3 + 3” design. Eligible patients (pts) include adults with R/R AL ineligible for standard therapy. Initially pts were enrolled agnostic to molecular status. A subsequent amendment introduced quotas for KMT2Ar (MLL1r), NPM1 and other known menin-dependent mutations: CEBP/A, MLL1-PTD, MN1, NUP98, NUP214, PICALM-AF10, SETBP1. Prior exposure to reversible menin inhibitor therapy is permitted. Subjects receive BMF-219 daily for continuous 28-day cycles until progression/intolerability. There are 2 parallel dose-escalation arms: pts not taking (Arm A) or taking (Arm B) moderate or strong CYP3A4 inhibitors. The study is ongoing and accruing in the escalation. Expansion cohorts will enroll pts to obtain further safety and efficacy data at the OBD/RP2D. Results: As of data cutoff of 7/24/2023, 26 pts with R/R AL (24 AML; 2 ALL) are enrolled; 7 remain on study treatment. Baseline characteristics include 17(65%) males and 9(35%) females with a median age of 57.5 years (range 33-84). There is a median of 4 (range 1-8) prior lines of therapy and 11 (42%) with prior HSCT(s). Six pts (23%) had KMT2Ar, 3 (12%) KMT2A-PTD, 4 (15%) NPM1, and 13 (50%) WT for KMT2A and NPM1. Dosing began with single-patient cohorts at 100 mg QD (Arm A) and 25 mg QD (Arm B) and has been escalated through 4 dose levels. Thus far, pts have been dosed up to 500 mg QD (Arm A) and 125 mg QD (Arm B). BMF-219 exposures were comparable between arms, with ~2-4-fold higher exposures observed with co-administration of a moderate or strong CYP3A4 inhibitor. At the highest dose (DL4) in which PK was evaluated, Arm A (500 mg QD) and Arm B (125 mg QD), pts on average achieved ~50% of target exposure (2000 ng*hr/mL) with some pts surpassing it. Higher QD dosing or corresponding BID dosing is expected to achieve desired exposure. BMF-219 has generally been well tolerated with no DLTs observed and no discontinuations due to treatment-related toxicities. No related QTc prolongation was observed. At the time of data cutoff, 23 of 26 pts were included in the safety population. Common TRAEs (≥10%) include vomiting 13% (3) and Differentiation Syndrome (DS) 13% (3). No Grade 5 TRAEs were reported. The only common Grade ≥3 TRAE (≥5%) was DS 13% (3). The efficacy evaluable population includes AML pts who meet the following criteria: dosed at or near predicted efficacious dose (500 mg or above [Arm A]; 125 mg or above [Arm B]), had known menin-dependent mutations, and completed at least one scheduled response assessment (or had a minimum of 7 doses if discontinued prematurely). Thus far, 2 of 5 efficacy evaluable patients achieved a complete remission (1 CR; 1 CRi) and both continue BMF-219 treatment. Patient A: 39/M, NUP98-NSD1, ECOG=0, 500 mg QD, Arm A, 4 prior lines of treatment including intensive chemotherapy and allo-HSCT. At C1D27, marrow blasts were reduced to 6% from 13% at study entry. The patient achieved CR at C2D28 with 0% blasts.Patient B: 70/F, NPM1m, ECOG=1, 125 mg QD, Arm B, 1 prior line of treatment with decitabine and an investigational agent. At C1D28, marrow blasts were reduced to 34% from 52% at study entry. The patient achieved CRi with 3% blasts at C2D28. Conclusion: BMF-219 is generally well tolerated with no DLT observed (and able to be taken with and without CYP3A4 inhibitors) with no pts discontinuing therapy due to toxicity. BMF-219 dose escalation is ongoing and approaching target exposure. BMF-219 demonstrates early signs of clinical activity in different genomic subgroups. The trial is ongoing and includes enrollment for pts diagnosed with AL, DLBCL, MM and CLL.

Abstract Background Two independent placebo-controlled clinical trials conducted prior to SARS-CoV-2 Omicron demonstrated that sotrovimab and remdesivir reduced hospitalization among high-risk outpatients with mild to moderate COVID-19. However, their effectiveness have not been directly compared. Methods This retrospective study examined all high-risk outpatients with mild to moderate COVID-19 who received either remdesivir or sotrovimab at Mayo Clinic during the Omicron BA.1 surge from January to March 2022. COVID-19-related hospitalization or death within 28 days were compared between the two treatment groups. Results Among 3,257 patients, 2,158 received sotrovimab and 1,099 received remdesivir. Patients treated with sotrovimab were younger (median age, 60 vs. 69 years) and had lower comorbidity (Monoclonal Antibody Screening Score, 5 vs. 6; Charlson Comorbidity Index, 3 vs. 4), but were more likely to be immunocompromised (47.3% vs. 30.2%) than remdesivir-treated patients. The majority (89%) had received at least one dose of COVID-19 vaccine (median, 3 doses [IQR 2-3] for both groups). COVID-19-related hospitalization (1.5% and 1.0% in remdesivir and sotrovimab groups, respectively, p=.15) and mortality within 28 days (0.4% in both groups, p=.82) were similarly low. A propensity score weighted analysis demonstrated no significant difference in the rates of COVID-related hospitalization and death within 28 days between the two groups. Conclusion This study demonstrated favorable outcomes that were not significantly different between patients treated with remdesivir or sotrovimab. As sotrovimab is no longer authorized, these results support the continued use of remdesivir for treating high-risk patients with COVID-19 during the current Omicron-predominant epoch.

Abstract Background Remdesivir is FDA-approved for the treatment of hospitalized patients with severe COVID-19. Many patients improve clinically to allow for hospital dismissal before completing the 5-day course. In prior work, those who continued remdesivir in an outpatient setting had better outcomes. Here, we assessed patients’ perspectives and the economic impact of this outpatient practice. Methods During a one-year period, 3,029 patients received remdesivir for COVID-19 in the hospital; of them, 542 were dismissed to continue remdesivir in the outpatient setting and were surveyed. The cost of care was compared between those who remained in the hospital vs. those who were dismissed. Results 470 of 542 patients were surveyed, and 93 (19.8%) responded. Responders were older than non-responders (median, 63 vs. 58 years). The majority (70.5%) had symptoms resolved by the time of the survey. Ten patients (11.4%) had persistent symptoms attributed to long COVID-19, including fatigue (30.1%), brain fog (23.7%), and insomnia (18.3%). 73.8% were excited to learn about the outpatient remdesivir program. The majority (81.0%) felt that receiving therapy at home was the right decision; 79.5% had support and felt the benefits of completing treatment at home. The majority were satisfied with communication before (75.6%) and during (80.5%) the outpatient appointment, information on benefits (80.3%) and risks (58.5%), time spent at the infusion center (88.6%), quality of care (82.3%) and overall experience (76.0%). The benefits of treatment were high-value (82.6%), while the infusions' cost, inconvenience, and discomfort were unimportant for most responders. After adjusting for gender, comorbidity score, and WHO scale, the predicted costs for the groups were $16,544 (inpatient) and $9,097 (outpatient) per patient (difference of $7,447; p< .01). During this study, we estimated a total of 1,077 hospital room-days were made available to other patients. Conclusion An outpatient remdesivir program that allowed for early dismissal was perceived favorably by patients hospitalized for COVID-19. The program resulted in significant cost and resource savings, the latter in terms of the availability of hospital rooms for other patients needing critical services. Disclosures Christina G.

Abstract Background Sequential vein grafting is utilized to revascularize multiple distal vascular territories in patients with diffusely diseased coronaries undergoing repeat coronary artery bypass grafting (CABG). However, sequential vein grafting is technically challenging due to the side-to-side anastomosis. This study expands on the usage of saphenous vein tributaries in sequential vein grafting (tributary technique) and its outcomes at a single institution. Methods A retrospective observational chart review was conducted on patients who underwent the proposed technique in our institution over three years. The primary outcome variables included all-cause mortality and freedom from major adverse cardiovascular events (MACE). A descriptive analysis was conducted to express the continuous variables as mean and standard deviation and categorical variables as frequency and percentages. Results The study included 187 patients with a mean follow-up duration of 24.8 ± 10.0 months and operative mortality of 1.7%. A total of 131 patients remained symptom-free starting from the date of surgery, and four cardiovascular mortalities were reported during the follow-up period. Conclusion The tributary technique is feasible and can be a potential option in repeat CABGs requiring multiple grafts in patients with adequate vein calibre in lower limbs.

AbstractPulmonary hypertension (PH) is a risk factor for mortality in patients with sarcoidosis. Severe PH in chronic lung disease has previously been defined as mean pulmonary arterial pressure (mPAP) ≥ 35 mmHg or mPAP 25 ≥ mmHg with cardiac index (CI) ≤ 2 L/min/m2. However, there is no clear definition denoting severity of sarcoidosis‐associated PH (SAPH). We aimed to determine pulmonary hemodynamic cut‐off values where transplant‐free survival was worse among patients with SAPH. This was a retrospective cohort analysis of the Registry of SAPH database focusing on pulmonary hemodynamic predictors of transplant‐free survival among patients with precapillary SAPH. Cox regression was performed to determine which pulmonary hemodynamic values predicted death or lung transplantation. Kaplan−Meier survival analysis was performed on statistically significant predictors to determine pulmonary hemodynamic cut‐off values where transplant‐free survival was decreased. Decreased transplant‐free survival occurred among SAPH patients with mPAP ≥ 40 mmHg and SAPH patients with pulmonary vascular resistance (PVR) ≥ 5 Woods units (WU). Transplant‐free survival was not decreased in patients who fulfilled prior criteria of severe PH in chronic lung disease. We identified new cut‐offs with decreased transplant‐free survival in the SAPH population. Neither cut‐off of mPAP ≥ 40 mmHg nor PVR ≥ 5 WU has previously been shown to be associated with decreased transplant‐free survival in SAPH. These values could suggest a new definition of severe SAPH. Our PVR findings are in line with the most recent European Society of Cardiology/European Respiratory Society guideline definition of severe PH in chronic lung disease.

Background: Complementary and alternative medicine (CAM) interventions are growing in popularity as possible treatments for long COVID symptoms. However, comprehensive analysis of current evidence in this setting is still lacking. Objective: This study aims to review existing published studies on the use of CAM interventions for patients experiencing long COVID through a systematic review. Design: Systematic review of randomized controlled trials (RCTs). Methods: A comprehensive electronic literature search was performed in multiple databases and clinical trial registries from September 2019 to January 2023. RCTs evaluating efficacy and safety of CAM for long COVID were included. Methodological quality of each included trial was appraised with the Cochrane ‘risk of bias’ tool. A qualitative analysis was conducted due to heterogeneity of included studies. Results: A total of 14 RCTs with 1195 participants were included in this review. Study findings demonstrated that CAM interventions could benefit patients with long COVID, especially those suffering from neuropsychiatric disorders, olfactory dysfunction, cognitive impairment, fatigue, breathlessness, and mild-to-moderate lung fibrosis. The main interventions reported were self-administered transcutaneous auricular vagus nerve stimulation, neuro-meditation, dietary supplements, olfactory training, aromatherapy, inspiratory muscle training, concurrent training, and an online breathing and well-being program. Conclusion: CAM interventions may be effective, safe, and acceptable to patients with symptoms of long COVID. However, the findings from this systematic review should be interpreted with caution due to various methodological limitations. More rigorous trials focused on CAM for long COVID are warranted in the future.

Background Alcohol-associated liver disease is increasing among females with an earlier onset and more severe disease at lower levels of exposure. However, there is paucity of literature regarding sex differences related to alcoholic hepatitis. Methods Hospitalized patients with alcoholic hepatitis were selected from the US Nationwide readmissions database 2019. In this cohort, we evaluated sex differences in baseline comorbidities, alcoholic hepatitis related complications and mortality. A subset of patients with alcoholic hepatitis who were hospitalized between January and June 2019 were identified to study sex differences in 6 month readmission rate, mortality during readmission, and composite of mortality during index hospitalization or readmission. Results Among 112 790 patients with alcoholic hepatitis, 33.3% were female. Female patients were younger [48 (38–57) vs. 49 (39–58) years; both P < 0.001] but had higher rates of important medical and mental-health related comorbidities. Compared with males, females had higher rates of hepatic encephalopathy (11.5% vs. 10.1; P < 0.001), ascites (27.9% vs. 22.5%; P < 0.001), portal hypertension (18.5% vs. 16.4%; P < 0.001), cirrhosis (37.3% vs. 31.9%; P < 0.001), weight loss (19.0% vs. 14.5%; P < 0.001), hepatorenal syndrome (4.4% vs. 3.8%; P < 0.001), spontaneous bacterial peritonitis (1.9% vs. 1.7%; P = 0.026), sepsis (11.1% vs. 9.5%; P < 0.001), and blood transfusion (12.9% vs. 8.7%; P < 0.001). Females had a similar in-hospital mortality rate (4.3%) compared to males (4.1%; P = 0.202; adjusted odds ratio (OR) 1.02, 95% CI (cardiac index) 0.89–1.15; P = 0.994). In the subset of patients (N = 58 688), females had a higher 6-month readmission rate (48.9% vs. 44.9%; adjusted OR 1.12 (1.06–1.18); P < 0.001), mortality during readmission (4.4% vs. 3.2%; OR 1.23 (1.08–1.40); P < 0.01), and composite of mortality during index hospitalization or readmission (8.7% vs. 7.2%; OR 1.15 (1.04–1.27); P < 0.01). Conclusion Compared to their male counterparts, females with alcoholic hepatitis were generally younger but had higher rates of comorbidities, alcoholic hepatitis related complications, rehospitalizations and associated mortality. The greater risks of alcohol-associated liver dysfunction in females indicate the need for more aggressive management.

The objective of this observational study is to determine whether vaccination for SARS-CoV-2 alters the clinical presentation of post-COVID conditions (PCC). Self-reported data provided by patients requesting care for PCC at the Mayo Clinic were analyzed to assess for a relationship between vaccination status prior to COVID infection and PCC symptoms. In all, 477 subjects were included in this study. In total, 245 (51.4%) were vaccinated. Vaccinated subjects with PCC reported less abdominal pain, anosmia, parosmia, chest pain/tightness, dizziness, numbness/tingling, dyspnea, spells/tremors, and weakness. For hospitalized patients who developed PCC, vaccinated patients reported less chest pain, cough, dizziness, and dyspnea. After applying Bonferroni correction for multiple comparisons, decreased abdominal pain remained significant. We conclude that vaccination against SARS-CoV-2 may reduce the symptoms of PCC, leading to improved morbidity and function. Further studies on the impact of vaccination on PCC and recovery are needed.

BACKGROUND: Premature menopause is a risk factor for accelerated cardiovascular aging, but underlying mechanisms remain incompletely understood. This study investigated the role of leukocyte telomere length (LTL), a marker of cellular aging and genomic instability, in the association of premature menopause with cardiovascular disease. METHODS: Participants from the UK Biobank and Women’s Health Initiative with complete reproductive history and LTL measurements were included. Primary analyses tested the association between age at menopause and LTL using multivariable-adjusted linear regression. Secondary analyses stratified women by history of gynecologic surgery. Mendelian randomization was used to infer causal relationships between LTL and age at natural menopause. Multivariable-adjusted Cox regression and mediation analyses tested the joint associations of premature menopause and LTL with incident coronary artery disease. RESULTS: This study included 130 254 postmenopausal women (UK Biobank: n=122 224; Women’s Health Initiative: n=8030), of whom 4809 (3.7%) had experienced menopause before age 40. Earlier menopause was associated with shorter LTL (meta-analyzed ß=−0.02 SD/5 years of earlier menopause [95% CI, −0.02 to −0.01]; P =7.2×10 -12 ). This association was stronger and significant in both cohorts for women with natural/spontaneous menopause (meta-analyzed ß=−0.04 SD/5 years of earlier menopause [95% CI, −0.04 to −0.03]; P <2.2×10 -16 ) and was independent of hormone therapy use. Mendelian randomization supported a causal association of shorter genetically predicted LTL with earlier age at natural menopause. LTL and age at menopause were independently associated with incident coronary artery disease, and mediation analyses indicated small but significant mediation effects of LTL in the association of menopausal age with coronary artery disease. CONCLUSIONS: Earlier age at menopause is associated with shorter LTL, especially among women with natural menopause. Accelerated telomere shortening may contribute to the heightened cardiovascular risk associated with premature menopause.
