Type 1 Spinal Muscular Atrophy
Brief summary
An open-label, multi-part, first-in-human study of oral branaplam in infants with Type 1 spinal muscular atrophy. The purpose of this study was to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy after 13 weeks; and to estimate the Maximum Tolerated Dose (MTD) of orally administered branaplam; and to identify the dose that was safe for long term use as well as that can provide durable efficacy optimal dosing regimen in patients with Type 1 SMA.
Detailed description
This was an open-label, multi-part, first-in-human, proof of concept study in infants with Type 1 spinal muscular atrophy who have exactly 2 copies of SMN2, to evaluate safety, tolerability, PK, PD and efficacy of oral branaplam after 13 weeks treatment. Parts 1,2 and 3 were intended to be non-confirmatory. In Part 1 of the study, patients were dosed once weekly with branaplam. The branaplam dose was escalated in subsequent cohorts until MTD was determined or when sufficient PK results confirmed that the MTD could not be reached due to a potential pharmacokinetic plateau at higher doses. A decision to dose escalate the next cohort was made after safety data was collected for 14 days following the first dose (14-day DLT window). PK was used to confirm that there was no accumulation of the compound. After 13 weeks treatment, participants in part 1 could enter an extension treatment phase until they discontinued from the study or were transferred into part 3. Part 2 of the study enrolled new patients into one 2 dose cohorts with once weekly dosing for 52 weeks. The branaplam dose was escalated in subsequent cohorts after 6 patients were enrolled and at least 3 patients from the previous cohort completed 13 weeks of treatment. After 52 weeks, patients may have continued treatment in part 3 if it was in the best interest of the patient. Part 3, participants from part 1 and 2 who have completed at least 52 weeks of banaplam treatment were elegible to continue receiving treatment as long as in the best interest of the patient. In all cases continuation of the treatment was done at a dose selected as optimum, considering existing safety as well as efficacy data.

In SMA type I, paradoxical breathing is often a sign of breathing problems where the pulmonary ribcage moves inward during inspiration rather than outward while the abdomen expands. In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration. |

| Summary of CHOP INTEND Total Score - Parts 1 and 3 and Parts 2 and 3 - FAS | Baseline, Week 52 and Month 6 of Part 3 | CHOP INTEND is a motor test measure for SMA Type 1 and similarly weak infants with neuromuscular disease. The CHOP INTEND provides a useful measure of motor skills and strength in this population. It is a 16 item, 64 point scale. Each item (motor skill) is given a score from zero to 4: zero indicates can't complete the movement, 1 to 3 indicates partial performance and a 4 indicates person can complete the movement on their own without assistance. These scores are added up to a possible total score of 64 and higher scores indicate better outcomes. In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration. |

It evaluates 8 items; grasp, head control, kicking, rolling over, sitting up, crawling, standing and walking. Motor skills are assigned a score of 0 to 3 to 5 points and zero means the child lacks that motor skill. The maximum score is 26 which is dependent on age, level of development and severity of disease. A higher score is a better outcome. This assessment was added with amendment 6, therefore no baseline was available. In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration. |

It evaluates 8 items; grasp, head control, kicking, rolling over, sitting up, crawling, standing and walking. Motor skills are assigned a score of 0 to 3 to 5 points and zero means the child lacks that motor skill. The maximum score is 26 which is dependent on age, level of development and severity of disease. A higher score is a better outcome. This assessment was added with amendment 6, therefore no baseline was available. In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration. |
| Ventilation Use for Parts 1 and 3 and Parts 2 and 3 - FAS | Baseline up to 82 months | BiBAP (bilevel positive airway pressure) ventilation is a 2 level breathing support which has a tube that connects to a mask.

Mean change from baseline in percentage of oxygen saturation is reported. Negative numbers indicate a decrease from baseline In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration. |
| Summary of Plasma Pharmacokinetic (PK) Parameter Area Under the Curve (AUCinf) for All Observation Periods - Part 1 - PAS | from 0 h to 168 h after first/single dose | The area under the plasma (or serum or blood) concentration-time curve from time zero to infinity \[mass x time / volume\] for all observations.

Number of Participants and HINE Motor Subscale Milestones (Ability to Sit, Stand or Walk Without Support) - FAS
HINE Section 2 is a standardized evaluation of motor function. It evaluates 8 items; grasp, head control, kicking, rolling over, sitting up, crawling, standing and walking. Motor skills are assigned a score of 0 to 3 to 5 points and zero means the child lacks that motor skill. The maximum score is 26 which is dependent on age, level of development and severity of disease. A higher score is a better outcome. This assessment was added with amendment 6, therefore no baseline was available. In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration.

Summary of CHOP INTEND Total Score - Parts 1 and 3 and Parts 2 and 3 - FAS
CHOP INTEND is a motor test measure for SMA Type 1 and similarly weak infants with neuromuscular disease. The CHOP INTEND provides a useful measure of motor skills and strength in this population. It is a 16 item, 64 point scale. Each item (motor skill) is given a score from zero to 4: zero indicates can't complete the movement, 1 to 3 indicates partial performance and a 4 indicates person can complete the movement on their own without assistance. These scores are added up to a possible total score of 64 and higher scores indicate better outcomes. In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration.

Ventilation Use for Parts 1 and 3 and Parts 2 and 3 - FAS
BiBAP (bilevel positive airway pressure) ventilation is a 2 level breathing support which has a tube that connects to a mask. It provides a different level of air pressure for inhalation vs. exhalation, whereas a CPAP (continuous positive airway pressure) only pumps one level of air pressure but is also non-invasiive. Invasive ventilation is delivered via an endotracheal or tracheostomy tube. In alignment with the study objectives and protocol defined analyses, secondary efficacy endpoints were analyzed according to the treatment group that participants were assigned at baseline (Part 1&3 and Part 2&3) irrespective of study dose or route of administration.
Time frame: Baseline up to 82 months
