About this study
Official title: APOLLO: A Phase 3 Multicenter, Multinational, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of Patisiran (ALN-TTR02) in Transthyretin (TTR)-Mediated Polyneuropathy (Familial Amyloidotic Polyneuropathy-FAP)
The purpose of this study is to evaluate the safety and efficacy of patisiran (ALN-TTR02) in patients with transthyretin (TTR) mediated amyloidosis. An open-label, single-arm, long-term follow-up extension study NCT02510261 (ALN-TTR02-006) was initiated to provide participants who completed this study with continued patisiran-LNP (lipid nanoparticle) treatment.

What is being measured
The primary outcome is the main question the study is designed to answer.
Modified Neuropathy Impairment Score +7 (mNIS+7)
The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in mNIS+7 at 18 months. The mNIS+7 is a composite score that quantitates motor, sensory, and autonomic neurologic impairment due to injury of large and small nerves. The minimum and maximum values are 0 and 304, respectively. A higher score indicates a worse outcome.
Measured: 18mo
Secondary outcomes (6)
Norfolk Quality of Life-Diabetic Neuropathy (Norfolk QoL-DN) Questionnaire
The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in Norfolk QoL-DN at 18 months. The Norfolk QoL-DN questionnaire is a standardized 35-item patient-reported outcomes measure that is sensitive to the different features of diabetic neuropathy - small fiber, large fiber, and autonomic nerve function. The minimum and maximum values are -4 and 136, respectively. A higher score indicates a worse outcome.
Measured: 18mo
Neurological Impairment Score-Weakness (NIS-W) Score
The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in NIS-W at 18 months. NIS-W is a measure of motor strength, comprised of cranial nerve and both upper and lower limb motor assessments. The minimum and maximum values are 0 and 192, respectively. A higher score indicates a worse outcome.
Measured: 18mo
Rasch-built Overall Disability Scale (R-ODS) Score
The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in R-ODS score at 18 months. The R-ODS is comprised of a 24-item linearly weighted scale that specifically captures activity and social participation limitations in patients. The minimum and maximum values are 0 and 48, respectively. A higher score indicates a better outcome.
Measured: 18mo
Timed 10-meter Walk Test (10-MWT, Gait Speed)
The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in 10-MWT at 18 months. Ability to ambulate (gait speed) was assessed through the 10-meter walk test (10-MWT). The walk had to be completed without assistance from another person; ambulatory aids such as canes and walkers were permitted.
Measured: 18mo
Modified Body Mass Index (mBMI)
The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in mBMI at 18 months. The nutritional status of patients was evaluated using the mBMI; calculated as the product of BMI (weight in kilograms divided by the square of height in meters) and serum albumin (g/L).
Measured: 18mo
Autonomic Symptoms Questionnaire (Composite Autonomic Symptom Score [COMPASS 31])
The difference between the patisiran (ALN-TTR02) and placebo groups in the change from baseline in COMPASS 31 at 18 months. The COMPASS 31 is a measure of autonomic neuropathy symptoms. The questions evaluated 6 autonomic domains (orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor). The minimum and maximum values are 0 and 100, respectively. A higher score indicates a worse outcome.
Measured: 18mo

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing patisiran (ALN-TTR02) and Sterile Normal Saline (0.9% NaCl) in people with TTR-mediated Amyloidosis and Amyloidosis, Hereditary, run by Alnylam Pharmaceuticals at 52 sites in 21 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 52 sites in United States, France, Spain, Brazil, Germany and 16 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 Sep 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Modified Neuropathy Impairment Score +7 (mNIS+7) (time frame: 18mo). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01960348, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2024; AzTrials last refreshed its copy on 8 Nov 2026.
