InVivo Therapeutics Announces Contemporary Thoracic SCI Registry Study (the “CONTEMPO Registry Study”) Findings

A compilation of neurological recovery data from three established SCI registries was used for the CONTEMPO Registry Study, including the North American Clinical Trials Network (NACTN), European Multicenter Study about Spinal Cord Injury (EMSCI), and Spinal Cord Injury Model Systems. A total of 170 patients were included from the three registries: 12 individuals from NACTN, 64 from EMSCI, and 94 from Model Systems. AIS conversion rates at approximately six months post-injury varied from 16.7% - 23.4% across the three registries.

In two of the registries, there was a skew of the patient population to low (T10-T12) thoracic injuries, representing 46-47% of the registry population. This compares to just four out of sixteen patients (25%) in follow-up in the INSPIRE study with low thoracic injuries. Patients with low thoracic injuries are known to have the best prognoses, and the conversion rates were the highest in the low thoracic group in all three registries and the INSPIRE study. When all three registries were normalized to the INSPIRE patient population distribution across T2-T5, T6-T9 and T10-T12 injury groups, the normalized conversion rate for CONTEMPO registries ranged from 15.5%-20.6%.

“The CONTEMPO study represents a valuable compilation of neurological recovery data from three established SCI registries. This compilation, which is first of its kind, can help guide the development of future clinical trial protocols and aid in the interpretation of the safety and potential clinical benefit of new therapies,” stated Dr. Guest.

“Given that published historical benchmarks for AIS conversion rates were used to establish the INSPIRE OPC of 25%, we were pleased to see that the CONTEMPO Registry Study results validated and supported our OPC,” Richard Toselli, Chief Executive Officer, said. “The CONTEMPO Study will be an important component of our planned Humanitarian Device Exemption (HDE) regulatory submission, and we were pleased to have Dr. Guest present topline findings of the CONTEMPO Registry Study in Orlando.”
