Context: Patients with hypopituitarism have increased morbidity and mortality. There is ongoing debate around the optimum glucocorticoid replacement therapy.Objective: To assess the effect of glucocorticoid replacement in hypopituitarism on corticosteroid metabolism and its impact on body composition.Design and patients: We assessed the urinary corticosteroid metabolite profile (using gas chromatography/mass spectrometry) and body ...

Background: Many patients with acromegaly report limitations of long-acting somatostatin receptor ligand (SRL) injections, including ongoing disease symptoms near cycle-end and injection-site pain. Oral octreotide capsules (OOC) may provide an alternative to monthly injections. The phase 3 CHIASMA OPTIMAL study assessed efficacy and safety of OOC in patients with acromegaly controlled on injectable SRLs.Methods: A multinational, randomized, placebo-contr...

Peptide long-acting somatostatin receptor ligands (SRLs) are a first line medical treatment for acromegaly but are not efficiently absorbed when delivered orally. Years of injections with SRLs are associated with variable dose delivery, injection site reactions, and excessive life burden. Paltusotine (CRN00808) is a nonpeptide small molecule somatostatin type 2 (sst2) receptor agonist with high oral bioavailability (70%) and a 42–50 hour terminal elimination half-life in...

Long-acting somatostatin receptor ligands (LA-SRLs) are a first line medical treatment for acromegaly but require monthly parenteral administration. Paltusotine (CRN00808) is a nonpeptide, small molecule somatostatin type 2 (SST2) receptor agonist with high oral bioavailability (70%), suitable for once daily, oral dosing. The recently reported results of the ACROBAT Edge study (NCT03789656) suggest that patients with acromegaly treated with injected SRLs can switch to once dai...

Introduction: In response to the proposed move to decommission genitoplasty surgery for DSD, we investigated parental views on surgery for girls with virilising 46XX Congenital Adrenal Hyperplasia (CAH).Materials and Methods: In this prospective study, after ethical approval, parents of surgically treated CAH girls completed an electronic questionnaire.Results: 50 parents were cont...

Introduction: Timing of DSD surgery is debated. This study aimed to investigate outcomes of genitoplasty in CAH and assess patient’s opinion on surgery.Materials and methods: In this ethically approved prospective study, surgically treated CAH girls ≥16 years completed an electronic questionnaire.Results27 patients were contacted 13 completed questionnaires, 10 declined, 4 did not reply. Current median age 27 ...

Objective: Remission rates in young people with Graves’ hyperthyroidism are <25% after a 2-yr course of thionamide antithyroid drug (ATD). Immunomodulatory agents might improve outcome by facilitating immune tolerance. We explored whether rituximab (RTX) would increase remission rates when administered with a short course of ATD.Design: This was an open label multi-centre single arm phase 2 trial in newly presenting young people (12-20y) with Gr...

Paltusotine is a once-daily, oral selective nonpeptide somatostatin receptor type 2 (SST2) agonist, which is in clinical development for the treatment of acromegaly. Maintenance of insulin-like growth factor 1 (IGF-1) control and toleration was demonstrated in phase 2 studies evaluating paltusotine in biochemically controlled (IGF-1 ≤1xULN) [ACROBAT Evolve (NCT03792555)] and uncontrolled (1> IGF-1 ≤2.5xULN) [ACROBAT Edge (NCT03789656)] patients with acromegaly ...

Paltusotine is a once-daily, oral, nonpeptide somatostatin receptor type 2 (SST2) specific agonist, in development for the treatment of acromegaly and neuroendocrine tumors. We report interim results from ACROBAT Advance (NCT04261712), an ongoing, multicenter, open-label, long-term extension study of paltusotine in subjects with acromegaly who previously completed either Phase 2 study ACROBAT Edge (NCT03789656) or Evolve (NCT03792555). ACROBAT Edge enrolled 47 subjects with el...

Objective: The phase 3 CHIASMA OPTIMAL study assessed efficacy and safety of oral octreotide capsules (OOC) in patients with acromegaly controlled on injectable somatostatin receptor ligands (SRLs). Sensitivity analyses were conducted for efficacy endpoints using two methods of imputation (i.e., the process of replacing clinical data with substitution values) to address missing data points due to some subjects reverting back to their prior injectable SRL treatment.<p class...
