    Incidence of Venous Thromboembolic Events in Patients With Endogenous Cushing Syndrome
    (Endocrine Society, 2021-05-03) Subbu, Karthik; Tariq, Zunera; Erickson, Dana Z.; Bancos, Irina; Donegan, Diane; Medicine, School of Medicine
    Background: Hypercortisolemia is a hypercoagulable state associated with increased risk of venous thromboembolic events (VTE). The reported incidence of VTE in patients with ACTH-dependent or independent Cushing Syndrome (CS) is variable, ranging from 3 to 14%. Our aim was to assess the incidence of clinically significant VTE among patients with endogenous CS and to identify risk factors for the development of VTE. Methods: We conducted a single center retrospective longitudinal study of adult patients diagnosed with endogenous CS between 2010 and 2020. Patients with a known prothrombotic disease (e.g. Factor V Leiden), insufficient data, or non-neoplastic hypercortisolism were excluded. Data collected included patient demographics, presenting symptoms, biochemical and radiological workup, treatment details, and incidence of clinically significant VTE. Results: A total of 114 patients (mean age of 45.55 ± 14.78 years, 79.8% women) followed for mean of 3.26 ± 2.9 years were included. Of the 114 patients, 58 (50.9%) had Cushing disease (CD), 40 (35.1%) had CS due to adrenal adenoma/hyperplasia, 6 (3.5%) had adrenocortical carcinoma (ACC), and 10 (8.8%) had ectopic Cushing syndrome (eCS). The overall incidence of VTE at any time point was 14/114 (12.3%); 11 (79%) VTEs were associated with presence of an additional VTE risk factor (8 surgery and 3 malignancy). Prior to any intervention for CS, 3 of 114 (2.6%) patients had a VTE. Surgery for CS (adrenalectomy, transsphenoidal surgery, tumor resection) was performed in 97 patients (85.1%) whereas 17 were treated medically (n=10), died before treatment (n=1) or observed (n=6). VTE occurred in 2 patients receiving medical therapy for CS. The post-operative incidence of VTE was 9 (9.3%; 4 in CD, 1 in adrenal CS, 3 in ACC, and 1 in eCS). VTE occurred ≤ 3-month post-operative in 4 patients (44.4%). Among the 5 patients in whom VTE occurred >3 months post-operative, 3 had recurrent metastatic ACC with hypercortisolemia and 2 were in remission (1 with CS and 1 with eCS). The median time from surgery to VTE occurrence was 315 days (8-1006). Compared to those who did not develop VTE, those who developed VTE had higher mean 24-hour urine free cortisol (4663.6 vs 558.21 mcg/dL; n = 100, P < 0.0001) and mean 1 mg overnight dexamethasone suppression test (36.3 vs 11.8 mcg/dL; n = 69, P = 0.0003), but similar mean late-night salivary cortisol (0.591 vs 0.790 ng/dL, n = 84, P = 0.71) at diagnosis of CS. Discussion: Among those with CS, the overall incidence of VTE was 12.3% and the majority of VTE were provoked (surgery, malignancy). Moreover, VTE was more likely in those with higher UFC and 1 mg overnight dexamethasone suppression test in our cohort. This suggests that in patients with CS who have an active malignancy, severe CS or those undergoing a surgical procedure may be at increased risk of VTE. Future studies should investigate the optimal type and duration of the VTE prophylaxis.

    Relacorilant, a Selective Glucocorticoid Receptor Modulator, Induces Clinical Improvements in Patients With Cushing Syndrome: Results From A Prospective, Open-Label Phase 2 Study
    (Frontiers Media, 2021-07) Pivonello, Rosario; Bancos, Irina; Feelders, Richard A.; Kargi, Atil Y.; Kerr, Janice M.; Gordon, Murray B.; Mariash, Cary N.; Terzolo, Massimo; Ellison, Noel; Moraitis, Andreas G.; Medicine, School of Medicine
    Introduction/purpose: Relacorilant is a selective glucocorticoid receptor modulator (SGRM) with no progesterone receptor activity. We evaluated the efficacy and safety of relacorilant in patients with endogenous Cushing syndrome (CS). Materials and methods: A single-arm, open-label, phase 2, dose-finding study with 2 dose groups (NCT02804750, https://clinicaltrials.gov/ct2/show/NCT02804750) was conducted at 19 sites in the U.S. and Europe. Low-dose relacorilant (100-200 mg/d; n = 17) was administered for 12 weeks or high-dose relacorilant (250-400 mg/d; n = 18) for 16 weeks; doses were up-titrated by 50 mg every 4 weeks. Outcome measures included proportion of patients with clinically meaningful changes in hypertension and/or hyperglycemia from baseline to last observed visit. For patients with hypertension, clinical response was defined as a ≥5-mmHg decrease in mean systolic or diastolic blood pressure, measured by a standardized and validated 24-h ABPM. For patients with hyperglycemia, clinical response was defined ad-hoc as ≥0.5% decrease in HbA1c, normalization or ≥50-mg/dL decrease in 2-h plasma glucose value on oral glucose tolerance test, or decrease in daily insulin (≥25%) or sulfonylurea dose (≥50%). Results: 35 adults with CS and hypertension and/or hyperglycemia (impaired glucose tolerance or type 2 diabetes mellitus) were enrolled, of which 34 (24 women/10 men) received treatment and had postbaseline data. In the low-dose group, 5/12 patients (41.7%) with hypertension and 2/13 patients (15.4%) with hyperglycemia achieved response. In the high-dose group, 7/11 patients (63.6%) with hypertension and 6/12 patients (50%) with hyperglycemia achieved response. Common (≥20%) adverse events included back pain, headache, peripheral edema, nausea, pain at extremities, diarrhea, and dizziness. No drug-induced vaginal bleeding or hypokalemia occurred. Conclusions: The SGRM relacorilant provided clinical benefit to patients with CS without undesirable antiprogesterone effects or drug-induced hypokalemia.
