A Study to Assess the Safety, Tolerability, and Pharmacokinetics of Multiple Doses of ISIS 396443 Delivered Intrathecally to Patients With Infantile-Onset Spinal Muscular Atrophy

This study will test the safety, tolerability, and pharmacokinetics of multiple doses of ISIS-SMNRx administered into the spinal fluid three times over the duration of the trial, in patients with Infantile-Onset Spinal Muscular Atrophy.

This study will test the safety, tolerability, and pharmacokinetics of multiple doses of ISIS-SMNRx administered into the spinal fluid three times over the duration of the trial, in patients with Infantile-Onset Spinal Muscular Atrophy. Two dose levels will be evaluated sequentially. The lowest dose level will be studied in a cohort of 4 patients, and the highest dose level will be studied in a cohort of 4-16 patients. All patients will receive active drug.

April 2014   (final data collection date for primary outcome measure)

Inclusion Criteria:

  • Genetic documentation of 5q SMA (homozygous gene deletion or mutation)
  • Onset of clinical signs and symptoms consistent with SMA at ≥ 21 days and <6 months (180 days) of age
  • At study entry, receiving adequate nutrition and hydration (with or without gastrostomy), in the opinion of the Site Investigator
  • Body weight >5th percentile for age using CDC guidelines
  • Medical care meets and is expected to continue to meet guidelines set out in the Consensus Statement for Standard of Care in SMA (Wang et al. 2007), in the opinion of the Site Investigator
  • Gestational age of 35 to 42 weeks and gestation body weight ≥2 kg
  • Reside within approximately 9 hours ground-travel distance from a participating study center for the duration of the study. Residence >2 hours ground-travel distance from a study center must obtain clearance from the Site Investigator and the study Medical Monitor
  • Able to complete all study procedures, measurements and visits and parent or guardian/subject has adequately supportive psychosocial circumstances, in the opinion of the Site Investigator

Exclusion Criteria:

  • Hypoxemia (O2 saturation awake <96% or O2 saturation asleep <96%, without ventilation support)
  • Presence of an untreated or inadequately treated active infection requiring systemic antiviral or antimicrobial therapy at any time during the screening period
  • History of brain or spinal cord disease that would interfere with the LP procedures, CSF circulation, or safety assessments
  • Presence of an implanted shunt for the drainage of CSF or an implanted CNS catheter
  • History of bacterial meningitis
  • Clinically significant abnormalities in hematology or clinical chemistry parameters, as assessed by the Site Investigator, at screening that would render the subject unsuitable for inclusion
  • Treatment with another investigational drug (e.g., albuterol, riluzole, carnitine, creatine, sodium phenylbutyrate, salbutamol, valproate, hydroxyurea etc), biological agent, or device within 90 days prior to enrollment or anytime during the study. Any history of gene therapy or cell transplantation
  • The subject's parent(s) or legal guardian(s) is unable to understand the nature, scope, and possible consequences of the study, or does not agree to comply with the protocol defined schedule of assessments
  • Ongoing medical condition that according to the Site Investigator would interfere with the conduct and assessments of the study. Examples are medical disability other than SMA that would interfere with the assessment of safety or would compromise the ability of the subject to undergo study procedures
