Products and pipelineEdit

Voretigene neparvovecEdit

Voretigene neparvovec, marketed under the tradename Luxturna, is a gene therapy approved by the Food and Drug Administration for treatment of Leber's congenital amaurosis, a rare genetic eye disease.[6]

Fidanacogene elaparvovecEdit

Fidanacogene elaparvovec, previously known by its study ID number SPK-9001,[7] is an experimental drug under investigation for treatment of hemophilia B. Spark partnered with pharmaceutical giant Pfizer to develop fidanacogene elaparvovec.[2] Fidanacogene elaparvovec is an adeno-associated viral vector which is designed to transfer a working copy of the Factor IX gene into the livers of patients who carry non-functioning copies.[8] In July, 2018 Pfizer said fidanacogene elaparvovec was entering late stage clinical trials.[9]

SPK-8011Edit

SPK-8011 is an experimental drug under investigation for treatment of hemophilia A. It is entering phase III clinical trials in the United States. The therapy transfers a working copy of the Factor VIII gene into patients who lack one. In Phase II clinical trials 2 of 7 patients receiving the highest dose of the drug suffered immune responses. One patient had to be hospitalized. The reactions against the treatment were seen as a set back, though Spark suggested the responses could be controlled with steroids and promised to move forward with Phase III testing.[10][11]

SPK-7001Edit

SPK-7001 is an experimental drug under investigation for treatment of choroideremia, a genetic disorder that causes blindness.[12]

SPK-3006Edit

SPK-3006 is an experimental drug under investigation for treatment of Pompe disease, a genetic disorder that leads to failure to correctly metabolize glycogen.[12]

SPK-1001Edit

SPK-1001 is an experimental drug under investigation for treatment of Batten disease, a fatal genetic, nervous system disorder.[12]
