Study summary

The study aimed to confirm long-term efficacy and safety of LCI699 for the treatment of patients with Cushing's disease. It was a pivotal trial which supported the registration of LCI699 for the treatment of patients with Cushing's disease in the US and the EU.

This is a phase lll, multi-center, double-blind, randomized withdrawal study of LCI699 following a 24 week, single-arm, open-label dose titration and treatment period which evaluated the safety and efficacy of LCI699 for the treatment of patients with Cushing's disease.

Read the detailed description

The primary objective compared the complete response rate at the end of the 8-week period of randomized withdrawal (Week 34) between patients randomized to continued osilodrostat therapy vs.

placebo. The key secondary objective assessed the complete response rate at the end of individual dose titration and treatment with osilodrostat in the initial single-arm, open label period (Week 24).

Eligible patients were randomized in a double-blinded fashion at Week 26 at a 1:1 ratio either to continue treatment with osilodrostat at the same dose or to matching placebo. Randomization was stratified by osilodrostat dose at Week 24 (≤ 5mg bid vs. >5mg bid); and history of pituitary irradiation (yes/no).

The study had four periods combined in the Core Period (Study Period 1 to 4) and an optional Extension Period. The optional Extension Period starting at Week 48.

Study Period 1 consisted of a single-arm, open-label, osilodrostat dose-titration in individual patients (Week 1 to Week 12). Dose adjustments were based on the mean of three 24-hour UFC (mUFC) values as measured by the central laboratory.

During study Period 2 (Week 13 to Week 24), osilodrostat efficacy and safety were assessed at the therapeutic dose determined during study Period 1. Patients whose mUFC became elevated during this period had their osilodrostat dose increased further, if it was tolerated, up to 30 mg bid. Such patients were followed for long-term safety and efficacy and were not considered responders for the key secondary endpoint, hence were not randomized in Study Period 3.

Study Period 3 was a double-blind, placebo-controlled randomized withdrawal (RW) Period (Week 26 to Week 34). In order to be eligible for randomization in study Period 3, patients had to have completed dose titration during study Period 1, and had to be classified as complete responders at Week 24 of study Period 2. Patients not eligible for randomization received open-label osilodrostat until the end of the Core Period (Week 48), unless there was a reason to discontinue from the study prematurely.

During study Period 3, mUFC was measured at scheduled visits every 2 weeks. However, patients were also allowed to have unscheduled visits at any time during the RW if they reported symptoms of hypercortisolism or hypocortisolism.

The dose of study drug remained unchanged for patients who maintained a normal mUFC and did not develop adverse events (AEs) related to study drug during RW. The Investigator could reduce or temporally withhold a dose of study drug for safety reasons at any time during the study, including the RW Period.

During this study period, a patient was discontinued from the RW Period and declared a nonresponder, if the mUFC increased to >1.5×ULN. After discontinuation from RW treatment, or at the end of the RW Period (Week 34), whichever came first, the patient resumed open-label osilodrostat at a dose selected by the Investigator.

Patients who discontinued from the study during the RW Period were no longer in the study, and consequently were not permitted to receive open-label osilodrostat and could not move to study Period 4.

Patients who discontinued from RW treatment due to lack of efficacy resumed open-label osilodrostat at the time of discontinuation, which could occur before Week 34. Patients who were not discontinued during RW resumed open-label osilodrostat at the end of RW (Week 34) and continued osilodrostat thereafter (study Period 4).

The Novartis study team, the patient, the Investigator, and all other site staff remained blinded to treatment assignment from the time of randomization to the time of database lock at the end of the Core Period. Novartis Drug Supply Management department members were unblinded in order to prepare the study drug supplies.

Study Period 4 was a single-arm, open-label therapy (end of Week 34 to Week 48). At the end of Week 34, all patients received open-label osilodrostat treatment. The Investigator had the discretion to select the dose during this period.

Patients continued open-label therapy until Week 48. At Week 48, patients had the option to enter an Extension Period, or discontinue osilodrostat at Week 48 to conclude with an end of Core Period visit 4 weeks off study drug (at Week 52).

Patients who continued to receive clinical benefit, as assessed by the study Investigator, and who wished to enter the Extension Period were re-consented at Week 48. Patients entered the Extension period without interruption of study drug or assessments. At the end of the study, patients who continued to benefit from treatment were offered to participate in a separate long-term safety follow-up study. The optional Extension Period ended after all patients completed Week 72 or discontinued early.

Terms in these criteria, in plain language(12)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

What researchers measure

Primary outcomes

  1. Percentage of Primary Efficacy Responder at Week 34 by Randomized Treatment and Strata

    To compare the complete response rate at the end of the 8-week period of randomized withdrawal between randomized patients.A primary efficacy responder is defined as a randomized patient who has mUFC ≤ ULN at Week 34 and who was neither discontinued (study or RW treatment) nor had osilodrostat dose increase above the level at Week 26 during the RW Period of the study. mUFC: mean urinary free cortisol; ULN: Upper Limit of Normal

  12. Actual Change From Baseline in Patient-Reported Outcomes (Cushing's Health-Related Quality of Life (QoL)) - Total Score

    Cushing's Disease Health-Related Quality of Life Questionnaire was developed to evaluate quality of life in patients with Cushing's syndrome. It is comprised of 12 items that capture patient responses on 7 concepts: daily activities, healing \& pain, mood \& self-confidence, social concerns, physical appearance, memory \& concern about the future. These items are measured on a 5- point Likert-type scale assessing how often or how much each item has been related to the patient's Cushing's disease in the previous 4 weeks. The raw score is calculated by summing the individual item scores prior to being standardized so that the total score ranges from 0 to 100. Content reliability, sensitivity to change \& psychometric properties have been validated in patients with Cushing's disease. Patients were asked to complete the questionnaire prior to clinical assessments being undertaken. Increases from baseline are indicative of an improvement.

    Time frame: Baseline, Week (W) 48, W72, Last available assessment

  13. Actual Change From Baseline in Patient-Reported Outcomes: Beck Depression Inventory-II (BDI-II)

    BDI-II is a patient-reported instrument developed to measure the severity of depression in adults \& adolescents aged 13 years \& older. It is designed to be completed by the patient on paper \& takes approximately 5 minutes to complete. The BDI-II consists of 21 items designed to assess the intensity of depression in clinical \& normal patients in the preceding 2 weeks. Items are rated on a 4-point severity scale of 0 ('not at all') to 3 ('extreme' form of each symptom) with differing response options for each item. A global score ranging from 0 to 63 is calculated with a higher score representing a greater level of depression. The following scoring guidelines for interpretation of BDI-II have been suggested (Smarr, 2011): Minimal range =0-13, Mild depression =14-19, Moderate depression =20-28 and Severe depression = 29-63. Patients were asked to complete the questionnaire prior to clinical assessments being undertaken. A reduction from baseline in BDI-II is indicative of an improvement.

  14. Actual Change in Patient-Reported Outcomes: EQ-5D-5L Utility Index

    The EQ-5D-5L questionnaire is a standardized measure of health status developed by the EuroQol Group in order to provide a simple, generic measure of health for clinical and economic appraisal. It is cognitively undemanding, taking only a few minutes to complete. Instructions to respondents are included in the questionnaire. The EQ-5D-5L measures 5 items on mobility, self-care, usual activities, pain/discomfort, anxiety/depression, measured on 5 levels: no problems, slight problems, moderate problems, severe problems, \& extreme problems. A utility index can be computed from the EQ 5D-5L descriptive system with utility scores ranging from -0.281 (worst imaginable health state) to 1 (best imaginable health state), with -0.281 representing an "unconscious" health state. A single index value is analyzed for the EQ-5D-5L score. An increase from baseline in the EQ-ED-5L utility index is indicative of an improvement.

    Time frame: Baseline, W48, W72, Last available assessment

SecondaryActual Change From Baseline in Patient-Reported Outcomes (Cushing's Health-Related Quality of Life (QoL)) - Total Score

Cushing's Disease Health-Related Quality of Life Questionnaire was developed to evaluate quality of life in patients with Cushing's syndrome. It is comprised of 12 items that capture patient responses on 7 concepts: daily activities, healing \& pain, mood \& self-confidence, social concerns, physical appearance, memory \& concern about the future. These items are measured on a 5- point Likert-type scale assessing how often or how much each item has been related to the patient's Cushing's disease in the previous 4 weeks. The raw score is calculated by summing the individual item scores prior to being standardized so that the total score ranges from 0 to 100. Content reliability, sensitivity to change \& psychometric properties have been validated in patients with Cushing's disease. Patients were asked to complete the questionnaire prior to clinical assessments being undertaken. Increases from baseline are indicative of an improvement.

SecondaryActual Change From Baseline in Patient-Reported Outcomes: Beck Depression Inventory-II (BDI-II)

BDI-II is a patient-reported instrument developed to measure the severity of depression in adults \& adolescents aged 13 years \& older. It is designed to be completed by the patient on paper \& takes approximately 5 minutes to complete. The BDI-II consists of 21 items designed to assess the intensity of depression in clinical \& normal patients in the preceding 2 weeks. Items are rated on a 4-point severity scale of 0 ('not at all') to 3 ('extreme' form of each symptom) with differing response options for each item. A global score ranging from 0 to 63 is calculated with a higher score representing a greater level of depression. The following scoring guidelines for interpretation of BDI-II have been suggested (Smarr, 2011): Minimal range =0-13, Mild depression =14-19, Moderate depression =20-28 and Severe depression = 29-63. Patients were asked to complete the questionnaire prior to clinical assessments being undertaken. A reduction from baseline in BDI-II is indicative of an improvement.

SecondaryActual Change in Patient-Reported Outcomes: EQ-5D-5L Utility Index

The EQ-5D-5L questionnaire is a standardized measure of health status developed by the EuroQol Group in order to provide a simple, generic measure of health for clinical and economic appraisal. It is cognitively undemanding, taking only a few minutes to complete. Instructions to respondents are included in the questionnaire. The EQ-5D-5L measures 5 items on mobility, self-care, usual activities, pain/discomfort, anxiety/depression, measured on 5 levels: no problems, slight problems, moderate problems, severe problems, \& extreme problems. A utility index can be computed from the EQ 5D-5L descriptive system with utility scores ranging from -0.281 (worst imaginable health state) to 1 (best imaginable health state), with -0.281 representing an "unconscious" health state. A single index value is analyzed for the EQ-5D-5L score. An increase from baseline in the EQ-ED-5L utility index is indicative of an improvement.
