ABSTRACT

BACKGROUND: Geographic atrophy is an advanced form of dry age-related macular degeneration that can lead to irreversible vision loss and high burden of disease. We aimed to assess efficacy and safety of avacincaptad pegol 2 mg in reducing geographic atrophy lesion growth. METHODS: GATHER2 is a randomised, double-masked, sham-controlled, 24-month, phase 3 trial across 205 retina clinics, research hospitals, and academic institutions globally. To be eligible, patients had to be aged 50 years or older with non-centrepoint-involving geographic atrophy and best corrected visual acuity between 20/25 and 20/320 in the study eye. Eligible patients were randomly assigned (1:1) to monthly avacincaptad pegol 2 mg administered as a 100 µL intravitreal injection or sham for the first 12 months. Randomisation was performed using an interactive response technology system with stratification by factors known to be of prognostic importance in age-related macular degeneration. Patients, investigators, study centre staff, sponsor personnel, and data analysts were masked to treatment allocation. The primary endpoint was geographic atrophy lesion size measured by fundus autofluorescence at baseline, month 6, and month 12. Efficacy and safety analyses were done in the modified intention-to-treat and safety populations, respectively. This trial is registered with ClinicalTrials.gov, NCT04435366. FINDINGS: Between June 22, 2020, and July 23, 2021, 1422 patients were screened for eligibility, of whom 448 were enrolled and randomly assigned to avacincaptad pegol 2 mg (n=225) or sham (n=223). One patient in the sham group did not receive study treatment and was excluded from analyses. There were 154 (68%) female patients and 71 (32%) male patients in the avacincaptad pegol 2 mg group, and 156 (70%) female patients and 66 (30%) male patients in the sham group. From baseline to month 12, the mean rate of square-root-transformed geographic atrophy area growth was 0·336 mm/year (SE 0·032) with avacincaptad pegol 2 mg and 0·392 mm/year (0·033) with sham, a difference in growth of 0·056 mm/year (95% CI 0·016-0·096; p=0·0064), representing a 14% difference between the avacincaptad pegol 2 mg group and the sham group. Ocular treatment-emergent adverse events in the study eye occurred in 110 (49%) patients in the avacincaptad pegol 2 mg group and 83 (37%) in the sham group. There were no endophthalmitis, intraocular inflammation, or ischaemic optic neuropathy events over 12 months. To month 12, macular neovascularisation in the study eye occurred in 15 (7%) patients in the avacincaptad pegol 2 mg group and nine (4%) in the sham group, with exudative macular neovascularisation occurring in 11 (5%) in the avacincaptad pegol 2 mg group and seven (3%) in the sham group. INTERPRETATION: Monthly avacincaptad pegol 2 mg was well tolerated and showed significantly slower geographic atrophy growth over 12 months than sham treatment, suggesting that avacincaptad pegol might slow disease progression and potentially change the trajectory of disease for patients with geographic atrophy.

ABSTRACT

The aim of this post-hoc analysis was to determine whether early symptom improvement with extended release quetiapine (quetiapine XR) may predict treatment outcome in patients with major depressive disorder. Data were from 6, double-blind, placebo-controlled studies of quetiapine XR (2 fixed-dose and 2 flexible-dose monotherapy and 2 adjunct studies) in adult patients with major depressive disorder. Montgomery-Åsberg Depression Rating Scale (MADRS) and Clinical Global Impression-Severity Score (CGI-S) were assessed at baseline, weeks 2, 4, and 6. Hamilton Rating Scale for Depression (HAM-D) was assessed at baseline and week 6. The MADRS improvement at week 2 (15%, 20%, 25%, 30%) was used to predict response and remission, based on MADRS (50% improvement; total score ≤ 12) or HAM-D (50% improvement; total score ≤ 7). The CGI-S improvement (1 point) at week 2 was used to predict final outcome (CGI-S score ≤ 2). The predictive value for early improvement with quetiapine XR was found to be "very strong" (Yule's Q coefficient, a combined measure of sensitivity and specificity) using 30% MADRS improvement as the threshold. This was relatively comparable for response and remission and for fixed-dose, flexible-dose, and adjunct studies. This was also observed for placebo. Exceptions were: adjunct studies (where predictivity was lower for ongoing antidepressant/placebo), and for remission (predictivity for remission appeared lower than for response with placebo). In conclusion, outcome at week 6 with quetiapine XR for a major depressive episode could be predicted by 30% improvement after 2 weeks, a finding that could give doctors confidence to continue treatment and may facilitate adherence in patients.

ABSTRACT

Safety and tolerability are important considerations when selecting patients' treatment for major depressive disorder. We report the long-term safety and tolerability of the nicotinic channel modulator dexmecamylamine (TC-5214), adjunct to selective serotonin reuptake inhibitors (SSRIs)/serotonin-norepinephrine reuptake inhibitors (SNRIs) in patients with major depressive disorder and who had an inadequate response to antidepressants. This 52-week, double-blind, placebo-controlled study explored the long-term safety and tolerability of dexmecamylamine. Patients were randomized 3:1 to receive flexibly dosed dexmecamylamine 1 to 4 mg adjunct to SSRI/SNRI or placebo plus SSRI/SNRI. The patient population comprised inadequate responders from 2 Phase III acute dexmecamylamine studies (NCT01157078 [study 002], NCT01153347 [study 004]) and de novo patients who responded inadequately during a 6-week open-label antidepressant treatment period preceding randomization. Safety and tolerability were assessed by monitoring adverse events, vital signs, and physical and laboratory parameters. Descriptive statistical analyses were performed on most efficacy-related end points. Sustained efficacy was analyzed using logistic regression. Overall, 813 patients were randomized (610 received dexmecamylamine, 203 received placebo). In total, 82.4% and 84.6% of patients, respectively, experienced an adverse event. Adverse events occurring more frequently with dexmecamylamine vs placebo were constipation (19.6% vs 6.0%), dizziness (12.0% vs 7.0%), and dry mouth (9.7% vs 5.0%). Back pain (2.8% vs 8.5%), weight increase (4.4% vs 7.0%), and fatigue (5.6 % vs 7.5%) occurred more frequently in placebo-treated patients. No notable differences were observed between dexmecamylamine and placebo for any secondary end point. In this long-term study, safety and tolerability of dexmecamylamine were consistent with that reported in acute Phase III studies of dexmecamylamine.

ABSTRACT

Diabetics are at high risk for atherosclerotic cardiovascular disease (ASCVD) and are considered a coronary heart disease risk equivalent. The utility of aspirin in primary prevention of ASCVD in diabetic patients has been widely studied and is still debated. Overall, the current evidence suggests a modest benefit for reduction in ASCVD events with the greatest benefit among those with higher baseline risk, but at the cost of increased risk of gastrointestinal bleeding. Diabetic patients at higher risk (with 10-year ASCVD risk >10 %) are generally recommended for aspirin therapy if bleeding risk is felt to be low. A patient-provider discussion is recommended before prescribing aspirin therapy. Novel markers such as coronary artery calcium scores and high-sensitivity C-reactive protein may help refine ASCVD risk prediction and guide utility for aspirin therapy. This article will review the literature for the most up-to-date studies evaluating aspirin therapy for primary prevention of ASCVD in patients with diabetes.

ABSTRACT

Problems with the efficacy of second-generation antipsychotics on negative symptoms and cognition have highlighted the need for further development of drugs targeting central nervous system neurotransmitter systems other than dopamine. One target in development is neurokinin 3 (NK(3)) tachykinin receptors, which are coreleased and interact with dopamine. This study investigates the efficacy, tolerability, and cognitive effects of AZD2624, a selective, orally active NK(3) receptor antagonist, in symptomatic patients with schizophrenia. Patients were randomly assigned to 1 of 3 treatment groups: AZD2624 40 mg, placebo, or olanzapine 15 mg. Treatment lasted for 28 days, and the Positive and Negative Syndrome Scale, the Clinical Global Impression Severity Scale and Improvement Scales, and cognition as assessed by CogState were used as primary outcome measures. There were no significant differences in patients treated with AZD2624 versus placebo on change in Positive and Negative Syndrome Scale total score and Clinical Global Impression Severity Scale; in addition, no change in CogState measures was found. Results of the trial do not support a role for the NK(3) antagonist AZD2624 as a therapeutic treatment for acute schizophrenia when used as monotherapy.

ABSTRACT

PURPOSE: To evaluate the impact of reduction in geographic atrophy (GA) lesion growth on visual acuity in the GATHER trials using categorical outcome measures. DESIGN: Randomized, double-masked, sham-controlled phase 3 trials. PARTICIPANTS: Aged ≥50 years with noncenter point-involving GA and best-corrected visual acuity (BCVA) of 25 to 80 ETDRS letters in the study eye. METHODS: GATHER1 consisted of 2 parts. In part 1, 77 patients were randomized 1:1:1 to avacincaptad pegol (ACP) 1 mg, ACP 2 mg, and sham. In part 2, 209 patients were randomized 1:2:2 to ACP 2 mg, ACP 4 mg, and sham. In GATHER2, patients were randomized 1:1 to ACP 2 mg (n = 225) and sham (n = 223). A post hoc analysis of 12-month data for pooled ACP 2 mg and sham groups is reported. MAIN OUTCOME MEASURES: Proportion of study eyes that experienced ≥10-, ≥15-, or ≥20-BCVA ETDRS letter loss from baseline to month 12; time-to-event analysis of persistent vision loss of ≥10, ≥15, or≥ 20 BCVA letters from baseline at ≥2 consecutive visits over 12 months; proportion of study eyes with BCVA loss to a level below driving eligibility threshold at month 12 among those eligible to drive at baseline. RESULTS: Lower proportions of study eyes experienced ≥10-, ≥15-, or ≥20-BCVA letter loss from baseline over 12 months with ACP 2 mg (11.6%, 4.0%, and 1.6%, respectively) versus sham (14.1%, 7.6%, and 4.5%, respectively). There was a reduction in the risk of persistent loss of ≥15 BCVA ETDRS letters with ACP 2 mg (3.4%) versus sham (7.8%) through 12 months. A lower proportion of study eyes treated with ACP 2 mg reached the threshold for driving ineligibility versus sham by 12 months. CONCLUSIONS: Treatment with ACP 2 mg delayed the risk of progression to persistent vision loss (i.e., ≥10-, ≥15-, and ≥20-BCVA letter loss or BCVA loss to a level below driving eligibility threshold) versus sham over 12 months.

ABSTRACT

There is increasing evidence that Takotsubo cardiomyopathy behaves more like a highly variable and dangerous syndrome than an isolated cardiomyopathy. In this case report, we describe a case of Takotsubo cardiomyopathy complicated by complete heart block. We discuss the potential mechanisms for its etiology and examine the need for pacemaker placement.

ABSTRACT

BACKGROUND/OBJECTIVES: To assess the safety and efficacy of avacincaptad pegol (ACP), a C5 inhibitor, for geographic atrophy (GA) secondary to age-related macular degeneration (AMD) over an 18-month treatment course. SUBJECTS/METHODS: This study was an international, prospective, randomized, double-masked, sham-controlled, phase 2/3 clinical trial that consisted of 2 parts. In part 1, 77 participants were randomized 1:1:1 to receive monthly intravitreal injections of ACP 1 mg, ACP 2 mg, or sham. In part 2, 209 participants were randomized 1:2:2 to receive monthly ACP 2 mg, ACP 4 mg, or sham. The mean rate of change of GA over 18 months was measured by fundus autofluorescence. RESULTS: Compared with their respective sham cohorts, monthly ACP treatment reduced the mean GA growth (square root transformation) over 18 months by 28.1% (0.168 mm, 95% CI [0.066, 0.271]) for the 2 mg cohort and 30.0% (0.167 mm, 95% CI [0.062, 0.273]) for the 4 mg cohort. ACP treatment was generally well tolerated over 18 months, with most ocular adverse events (AEs) related to the injection procedure. Macular neovascularization (MNV) was more frequent in both 2 mg (11.9%) and 4 mg (15.7%) cohorts than their respective sham control groups (2.7% and 2.4%). CONCLUSIONS: Over this 18-month study, ACP 2 mg and 4 mg showed continued reductions in the progression of GA growth compared to sham and continued to be generally well tolerated. A pivotal phase 3 GATHER2 trial is currently underway to support the efficacy and safety of ACP as a potential treatment for GA.

ABSTRACT

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT: • AZD7325 is an orally administered, potent, selective gamma-amino-butyric acid (GABA(A) ) α2,3 receptor modulator intended for the treatment of anxiety. • The induction effects of AZD7325 on CYP1A2 and CYP3A4 have not been systematically studied. WHAT THIS STUDY ADDS: • The in vitro studies showed that AZD7325 was a moderate CYP1A2 inducer and potent CYP3A4 inducer. • The follow-up clinical studies in healthy volunteers demonstrated that the expected efficacious daily dose of AZD7325 only weakly induced the pharmacokinetics of the CYP3A4 sensitive substrate, midazolam, and had no effect on the pharmacokinetics of the CYP1A2 substrate, caffeine. There was no apparent change in AZD7325 exposure following co-administration of midazolam or caffeine compared with AZD7325 alone. • The study demonstrated that clinical exposure of the inducer plays a critical role in the determination of cytochrome P450 induction risk of a drug candidate. AIM(S): To investigate the potential of AZD7325 to induce CYP1A2 and CYP3A4 enzyme activities. METHODS: Induction of CYP1A2 and CYP3A4 by AZD7325 was first evaluated using cultured human hepatocytes. The effect of multiple doses of 10 mg AZD7325 on the pharmacokinetics of midazolam and caffeine was then examined in healthy subjects. RESULTS: The highest CYP1A2 and CYP3A4 induction responses were observed in human hepatocytes treated with 1 or 10 µm of AZD7325, in the range of 17.9%-54.9% and 76.9%-85.7% of the positive control responses, respectively. The results triggered the further clinical evaluation of AZD7325 induction potential. AZD7325 reached a plasma C(max) of 0.2 µm after 10 mg daily dosing to steady-state. AZD7325 decreased midazolam geometric mean AUC by 19% (0.81-fold, 90% CI 0.77, 0.87), but had no effect on midazolam C(max) (90% CI 0.82, 0.97). The mean CL/F of midazolam increased from 62 l h(-1) (midazolam alone) to 76 l h(-1) when co-administered with AZD7325. The AUC and C(max) of caffeine were not changed after co-administration of AZD7325, with geometric mean ratios (90% CI) of 1.17 (1.12, 1.23) and 0.99 (0.95, 1.03), respectively. CONCLUSIONS: While AZD7325 appeared to be a potent CYP3A4 inducer and a moderate CYP1A2 inducer from in vitro studies, the expected efficacious dose of AZD7325 had no effect on CYP1A2 activity and only a weak inducing effect on CYP3A4 activity. This comparison of in vitro and in vivo results demonstrates the critical role that clinical exposure plays in evaluating the CYP induction risk of a drug candidate.

ABSTRACT

The pathophysiology of dry age-related macular degeneration (AMD) and specifically geographic atrophy (GA) has been linked to the complement cascade. This cascade is part of the innate immune system and is made up of the classical, alternative, and lectin pathways. The pathways comprise a system of plasma and membrane-associated serum proteins that are activated with identification of a nonself entity. A number of these proteins have been implicated in the development and progression of dry AMD. The three pathways converge at C3 and cascade down through C5, making both of these proteins viable targets for the treatment of dry AMD. In addition, there are a number of complement factors, CFB, CFD, CFH, and CFI, which are potential therapeutic targets as well. Several different complement-directed therapeutics are being studied for the treatment of dry AMD with the hope that one of these approaches will emerge as the first approved treatment for GA.

ABSTRACT

Atrial septal aneurysm (ASA) is a condition involving the bulging of the interatrial septum into one or both of the atrial chambers. We present the case of an ASA found on transesophageal echocardiogram in a patient who presented with exertional dyspnea. This case report aims to highlight the growing clinical association of ASA with arterial embolism through various mechanisms and emphasize the unknown aspects of clinical management for such patients. While there are currently no clear recommendations on whether to start anticoagulation after an ASA is diagnosed, many suggest a careful patient-centered approach for such decisions due to the reported increased risk of thromboembolic events. Further studies regarding the significance of ASA and cardioembolic events are needed.

ABSTRACT

BACKGROUND Pulmonary vein isolation is a method of cardiac ablation therapy used to treat irregular heart rhythm, including atrial fibrillation (AF). This report presents a case of esophagopericardial fistula (EPF) and pneumopericardium as a complication of pulmonary vein isolation in a 62-year-old man with AF. CASE REPORT We report the rare case of a 62-year-old man with a medical history of persistent atrial fibrillation status after ablation 3 days prior to his initial Emergency Department visit for chest pain. Acute coronary syndrome was ruled out with normal electrocardiogram, echocardiography, and troponin tests. Fluid overload and sotalol adverse effects were presumed to be the cause of his symptoms. We discontinued sotalol with diuresis and he was discharged home when his chest pain subsided. Nine days later, he returned to the Emergency Department with worsening similar symptoms and was eventually diagnosed with EPF and pneumopericardium on a computed tomography scan of the chest with contrast. He was managed with esophagogastroduodenoscopy and stent placement along with subxiphoid pericardial window and pericardial drain placement. The patient was discharged in stable condition after removing the pericardial drain. At 10-day and 1-month follow-up, he had no recurrent symptoms. CONCLUSIONS This report shows that although EPF with pneumopericardium is a rare complication of pulmonary vein isolation, it should be rapidly diagnosed and treated as a life-threatening emergency.

ABSTRACT

There are few major adverse events after the coronavirus disease 2019 (COVID-19) vaccination. However, increasing cases of myocarditis and pericarditis are being reported to the Vaccine Adverse Event Reporting System (VAERS) in young people, primarily after the second dose of messenger RNA (mRNA) COVID-19 vaccines. We present a case series of myopericarditis post mRNA (Moderna) and myocarditis post vector-based (Johnson & Johnson) COVID-19 vaccines. We intend to highlight the importance of early diagnosis and treatment of vaccine-related myocarditis to reduce mortality and morbidity.

ABSTRACT

PURPOSE: Studies examining seizures (Szs) and epileptiform abnormalities (EAs) using continuous EEG in acute ischemic stroke (AIS) are limited. Therefore, we aimed to describe the prevalence of Sz and EA in AIS, its impact on anti-Sz drug management, and association with discharge outcomes. METHODS: The study included 132 patients with AIS who underwent continuous EEG monitoring >6 hours. Continuous EEG was reviewed for background, Sz and EA (lateralized periodic discharges [LPD], generalized periodic discharges, lateralized rhythmic delta activity, and sporadic epileptiform discharges). Relevant clinical, demographic, and imaging factors were abstracted to identify risk factors for Sz and EA. Outcomes included all-cause mortality, functional outcome at discharge (good outcome as modified Rankin scale of 0-2 and poor outcome as modified Rankin scale of 3-6) and changes to anti-Sz drugs (escalation or de-escalation). RESULTS: The frequency of Sz was 7.6%, and EA was 37.9%. Patients with Sz or EA were more likely to have cortical involvement (84.6% vs. 67.5% P = 0.028). Among the EAs, the presence of LPD was associated with an increased risk of Sz (25.9% in LPD vs. 2.9% without LPD, P = 0.001). Overall, 21.2% patients had anti-Sz drug changes because of continuous EEG findings, 16.7% escalation and 4.5% de-escalation. The presence of EA or Sz was not associated with in-hospital mortality or discharge functional outcomes. CONCLUSIONS: Despite the high incidence of EA, the rate of Sz in AIS is relatively lower and is associated with the presence of LPDs. These continuous EEG findings resulted in anti-Sz drug changes in one-fifth of the cohort. Epileptiform abnormality and Sz did not affect mortality or discharge functional outcomes.

ABSTRACT

Anomalous coronary artery from the opposite sinus (ACAOS) is an uncommon, yet highly variable anatomical abnormality. These coronary anatomy variants are often discovered incidentally during cardiac catheterization. These variants can be challenging intraoperatively and require adjustment by the operator. We present the case of a 93-year-old female who presented for shortness of breath due to severe mitral regurgitation (MR), who was found to have an anomalous left main coronary artery (LMCA) from the right sinus of Valsalva (RSOV). This asymptomatic finding was managed conservatively and patient underwent successful MitraClip treatment.

ABSTRACT

Myxoma is a rare benign tumor of the heart. Cardiac myxomas are the most common primary cardiac tumor in adults, commonly found within the left atrium. It can occur at any age and is more common in females than males. This case report aims to identify the clinical symptoms of cardiac myxoma, which can be life-threatening if neglected. Here, we present the case of a 30-year-old female with past smoking history. For the past three to four weeks before this hospitalization, her symptoms worsened including shortness of breath with exertion, dry cough, and pleuritic chest pain. Outpatient treatment with antibiotics and nebulizers did not relieve her symptoms. She went to the emergency room and underwent computed tomography of the chest with contrast showing bilateral lower lobe pulmonary emboli and a large mass in the right atrium. Intravenous unfractionated heparin was initiated. A transthoracic echocardiogram confirmed a 3.76 cm × 4.95 cm mass in the right atrium. The patient underwent surgical resection of the right atrial mass the following day and was discharged four days later in a stable condition. Pathology of the mass confirmed atrial myxoma.

ABSTRACT

Primary cardiac tumors are an incredibly rare finding. Cardiac myxomas are the most primary cardiac tumors that often occur within the left atrium. When left untreated, they pose a high risk of causing hemodynamic collapse by obstruction or can embolize and result in thromboembolic stroke. The presentation of cardiac myxoma varies greatly and can be associated with significant morbidity and mortality when undiagnosed. A careful physical examination and high degree of suspicion is crucial in early diagnosis and intervention. Our team presents a 46-year-old female patient with no significant past medical history that presented to the emergency department with a neurological deficit that was concerning for a transient ischemic attack. Initial laboratory workup and electrocardiogram was suggestive for pulmonary embolism; however, upon evaluation with imaging, the patient was found to have a 1.6 × 3.4 cm mass fixed to the mitral leaflet that was then confirmed on transthoracic echocardiography. Our patient was found to have non-obstructive coronary artery disease on cardiac catheterization and ultimately underwent successful mass resection by cardiothoracic surgery.

ABSTRACT

OBJECTIVES: To evaluate and compare the 2 surgical approaches of urethral reconstruction for management of refractory female urethral strictures (FUS) in a prospective randomized setting. Early surgical reconstruction is becoming the preferred management strategy for recurrent FUS. Reconstructive techniques have been described as using either dorsal (12-o'clock) or ventral approach (6-o'clock), each with their own advantages. To our best knowledge, a direct comparison between the 2 techniques to prospectively compare outcomes hasn't been made. METHODS: We performed a prospective randomized study in a single tertiary care center on a total of 24 patients, randomizing them into 2 groups of 12 patients each. One group underwent dorsal onlay and other underwent ventral onlay urethroplasty. Preoperative, intraoperative and postoperative outcomes were evaluated and compared for the 2 approaches. RESULTS: There was high success rate (91%) with significant but comparable improvements in flow rates, post void residue and symptomatic outcomes without any major complication. There was 1 recurrence of stricture each in both groups. Important technical differences were noted with easier meatus preservation, lesser bleeding and wider operative field in the ventral approach, while the dorsal approach proving better in distal urethral strictures requiring meatal reconstruction. CONCLUSION: Both approaches of urethroplasty present a very promising modality of management of FUS with comparable outcomes but with important technical differences which must be considered to best tailor the approach for each patient.
