CLEOPATTRA: A Research Study to Look at the Effects of Treatment With a Medicine Called Coramitug (NNC6019-0001) in People With Heart Failure Due to Transthyretin Amyloid (ATTR) Amyloidosis
- Conditions
- Transthyretin Amyloid Cardiomyopathy (ATTR CM)
- Interventions
- Drug: Placebo (NNC6019-0001)
- Registration Number
- NCT07207811
- Lead Sponsor
- Novo Nordisk A/S
- Brief Summary
This study will find out if a new medicine called NNC6019-0001 can help reduce the risk of heart-related death and illness in participants with a condition called transthyretin amyloid cardiomyopathy (ATTR-CM), which affects the heart. Participants will either receive NNC6019-0001 or a placebo (a treatment with no active medicine), and which one they get is decided by chance. Everyone in the study will continue receiving their usual heart treatments as recommended by their doctor.

- Male or female.

Cardiac amyloid infiltration demonstrated by:
- Cardiac biopsy positive for TTR amyloid, OR
- Grade 2 or 3 cardiac uptake at pyrophosphate (PYP)/diphosphono-1,2-propanodicarboxylic acid (DPD)/ hydroxymethylene diphosphonate (HMDP) scintigraphy with single-photon emission computed tomography (SPECT/CT) combined with an extracardiac biopsy positive for TTR amyloid, OR
- Grade 2 or 3 cardiac uptake at PYP/DPD/HMDP scintigraphy with SPECT/CT combined with normal serum free light chain ratio, and negative serum and urine protein electrophoresis with immunofixation (SPIE & UPIE).
Notes:
- Non-invasive diagnostic pathway will be confirmed by a centralised expert review.
- Bone tracer scintigraphy will be conducted using 99m-technetium (Tc)-labelled pyrophosphate (99mTc-PYP), 99mTc-labelled 3,3-diphosphono-1,2-propanodicarboxylic acid (99mTc-DPD), or 99mTc-labeled hydroxymethylene diphosphonate (99mTc-HMDP).

- Current diagnosis or history of amyloid light chain, other non-ATTR amyloidosis, known leptomeningeal amyloidosis, or multiple myeloma.
- HF not primarily caused by ATTR-CM (e.g., due to hypertension, valvular heart disease, or ischemic heart disease in the opinion of the investigator).
- Currently hospitalised or hospitalised within 14 days prior to screening.
- Currently treated with positive inotropic medication.
- Uncorrected, severe, haemodynamically significant, left-sided heart valve disease.
Note: Pre-existing echocardiogram up to 2 years old may be used.
- Acute coronary syndrome, unstable angina, stroke, transient ischemic attack, coronary revascularisation, cardiac device implantation, cardiac valve repair, or major surgery within 60 days of screening.
- Prior solid organ transplant or planned solid organ transplant during the study.
- Left ventricular ejection fraction (LVEF) less than 30 percent as assessed by centralised review of echocardiography.
- Presence or history of malignant neoplasm (other than basal or squamous cell skin cancer, in situ carcinomas of the cervix, carcinoma in situ/high-grade prostatic intraepithelial neoplasia [PIN], low-risk prostate cancer, or on stable therapy for prostate cancer) within 3 years before screening.
- End-stage renal disease (estimated glomerular filtration rate [eGFR] less than 15 mL/min/1.73 m^2 at screening, or chronic/intermittent haemodialysis or peritoneal dialysis).

Group Intervention Description NNC6019-0001 NNC6019-0001 Participants will receive NNC6019-0001 intravenously (IV). Participants will also have the option to continue any Standard of care (SoC) treatments as recommended by their medical health professional. Placebo Placebo (NNC6019-0001) Participants will receive placebo matched to NNC6019-0001 IV. Participants will also have the option to continue any SoC treatments as recommended by their medical health professional.
- Primary Outcome Measures
Name Time Method Number of occurrences of composite endpoint of cardiovascular (CV) deaths and recurrent CV events (CV hospitalisations and urgent heart failure [HF] visits) From baseline (week 0) to end of study (EOS) (up to approximately 4 years) Measured as count of events.
- Secondary Outcome Measures
Name Time Method Change in Kansas city cardiomyopathy questionnaire- clinical summary score (KCCQ-CSS) From baseline (week 0) to approximately 2 years Measured as score on a scale. KCCQ-CSS is a score derived from a 23-item patient-reported outcome (PRO) measure assessing health status in individuals with HF. The score ranges from 0 to 100, with higher scores indicating better health status.
Change in Kansas city cardiomyopathy questionnaire- overall summary score (KCCQ-OSS) From baseline (week 0) to approximately 2 years Measured as score on a scale. KCCQ-OSS is a score derived from a 23-item PRO measure assessing health status in individuals with HF. The score ranges from 0 to 100, with higher scores indicating better health status.
