E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is: • to study the benefit-risk of SPI-62 in participants with complications due to endogenous hypercortisolism related to autonomous cortisol secretion (ACS) in participants under current ‘standard of care’.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are: • to study the efficacy of SPI-62 in reducing morbidity and mortality related to hypercortisolism. • short-term progression, persistence, improvement, or resolution of clinical signs, markers, and symptom of hypercortisolism including: hyperglycemia, dyslipidemia, osteopenia, hypertension, and other features associated with endogenous hypercortisolism. • long-term safety as it relates to serious morbidity and mortality. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
The following are the main inclusion criteria: 1. Adults able to provide informed consent and willing to adhere to necessary reproductive precautions: •Reasonably effective contraception or abstinence •This excludes those below the local age of majority and those who are incarcerated or otherwise unable to freely provide consent 2. Participants with benign adrenal lesion(s) with proven ACS: •Clinical evidence of ACS confirmed by positive diagnostic tests per current guidelines1, 2 •This minimally includes a non-suppressed morning serum cortisol > 50 nmol/L (1.8 mcg/dL) after a 1 mg (or greater) overnight dexamethasone suppression test (ONDST) within the last 3 years attributable to otherwise benign ACS. ONDST results between 1.8 and 5 mcg/dL (139 nmol/L) should be repeated at screening to confirm non-suppression unless other testing (see point iii below) supports the diagnosis of ACS. •Testing should be confirmed by concurrent dexamethasone level adequate to provide suppression. Individuals using estrogen should meet further criteria accounting for potential increased corticosteroid binding globulin (CBG), e.g., free cortisol ≥ 2.2 nM (80 ng/dL), total serum cortisol ≥ 5 mcg/dL (138 nmol/L), or correction based on CBG measurement. •The dates and results of other tests used in confirmation of the diagnosis of ACS (e.g., non-suppressed repeat ONDST, elevated 24-hour UFC or LNSC, low DHEA-S or basal ACTH) must be recorded. •These benign adrenal nodule(s) may be either unilateral or bilateral (e.g., including primary macronodular adrenal hyperplasia), and should have characteristics inconsistent with malignancy. Such characteristics may include having an individual diameter ≤ 4 cm, homogenous texture, non-contrast computerized tomography ≤ 20 HU attenuation or washout (or comparable MRI iso-intensity or chemical shift), slow rate of growth, known benign etiology, or other evidence of a non malignant disease process. •Participants should have a documentation of a clinical need for intervention for consequences of glucocorticoid toxicity: •This includes treatment for, or evidence of ongoing metabolic consequences of ACS e.g., hyperglycemia, hypertension, hyperlipidemia, osteopenia, or other features of hypercortisolism. Such abnormalities should not be considered clinically relevant consequences of hypercortisolism if their onset was demonstrably present > 5 years prior to the evidence for hypercortisolism, or diagnosis of ACS and they do not meet any of the criteria noted in “b” below. •Presence of at least one of the following features in comorbidities potentially attributable to hypercortisolism: progressive, difficult to treat, associated with disproportionate end organ damage for age, unusual for age or discrepant from family history, or multiple comorbidities. •Surgery as first-line therapy should be discussed with participants having ACS, particularly those with a unilateral mass, and evidence of more severe glucocorticoid toxicity. The decision to pursue surgery or medical treatment should be based on patient preference and consensus of a multidisciplinary group of surgical, radiology, and endocrinology experts.
3. Participants should have a documentation of a clinical need for intervention for consequences of glucocorticoid toxicity: •This includes treatment for, or evidence of ongoing metabolic consequences of ACS e.g., hyperglycemia, hypertension, hyperlipidemia, osteopenia, or other features of hypercortisolism. Such abnormalities should not be considered clinically relevant consequences of hypercortisolism if their onset was demonstrably present > 5 years prior to the evidence for hypercortisolism, or diagnosis of ACS and they do not meet any of the criteria noted in “b” below. •Presence of at least one of the following features in comorbidities potentially attributable to hypercortisolism: progressive, difficult to treat, associated with disproportionate end organ damage for age, unusual for age or discrepant from family history, or multiple comorbidities. •Surgery as first-line therapy should be discussed with participants having ACS, particularly those with a unilateral mass, and evidence of more severe glucocorticoid toxicity. The decision to pursue surgery or medical treatment should be based on patient preference and consensus of a multidisciplinary group of surgical, radiology, and endocrinology experts.

E.4 | Principal exclusion criteria |
Participants will be excluded from the study if they satisfy any of the following criteria during screening unless otherwise stated: 1. Participants with adrenal Cushing’s syndrome (aCs), i.e., autonomous cortisol secretion having clear stigmata of Cushing’s syndrome, are excluded. 2. History of adrenalectomy or planned adrenalectomy within 4 months after enrollment (history of unilateral or incomplete bilateral adrenalectomy occurring before 4 months prior to enrollment is not exclusionary). 3. Hypercortisolism which is exogenous (iatrogenic or factitious), ACTH-dependent (Cushing’s disease or ectopic), cyclical, intermittent, or physiological (a.k.a. “pseudo-Cushing’s syndrome). Generally, a basal morning ACTH > 20 pg/mL is consistent with ACTH-dependent Cushing’s or pseudo-Cushing’s. 4. Participants who plan to undergo curative adrenal surgery within the next 3 years. 5. History of idiopathic thrombocytopenia. 6. History of cancer within 3 years likely to require further testing or intervention during the trial period or associated with a poor prognosis (e.g., other than treatable skin, thyroid, or early-stage prostate cancer, please consult with Medical Monitor for others). 7. Any major surgery, or significant post-operative sequelae, within 1 month prior to informed consent or planned during the trial. 8. Pregnant or lactating. 9. Other medical contraindications to SPI-62 therapy or other current or prior medical condition (including those listed in Section 4.3.2) or medication (as listed in Section 6.1 “Concomitant Therapy”) expected to interfere with the conduct of the trial or the evaluation of its results. a. Serious hypersensitivity to SPI-62 or its excipients b. Moderately or severely impaired renal function (estimated glomerular filtration rate < 60 mL/min/1.73m2) c. Uncontrolled, clinically significant hypo- or hyperthyroidism (abnormal TSH values are acceptable as long as the free T4 values are within 0.75-fold of the lower to 1.25-fold of the upper limits of the normal range) d. Hepatic disease including moderate or severe hepatic impairment (e.g., Child Pugh Class B or C; baseline elevations of liver transaminases [alanine aminotransferase and/or aspartate aminotransferase)] > 3 x ULN; or baseline elevations of total bilirubin > 1.5 x ULN [except in benign conditions, e.g., Gilbert’s syndrome]) e. Participants without hepatic impairment, but evidence of inadequately treated hepatitis B (HBsAg positive) or C (hepatitis C antibody positive unless viral load adequately suppressed). f. Baseline prolonged QT interval (defined as QTc > 500 msec or uncorrected QT > 600 msec), poorly controlled hypertension (resting supine blood pressure ≥ 180 mmHg systolic or ≥ 120 mmHg diastolic), or persistent or recurrent atrial fibrillation poorly managed on anticoagulant therapy. g. Positive test for SARS-CoV-2 active, transmissible infection within 4 weeks, or hospitalization for SARS-CoV-2 within 6 months, prior to randomization 10. Participation in any clinical trial within 3 months prior to the first dose of study drug, or longer depending on half-life of the investigational therapy. 11. Persons deprived of their liberty by a judicial or administrative decision, persons under psychiatric care, persons admitted to a sanitary or social institution for purposes other than research and major persons subject to a legal protection measure.
