Registration Number
NCT05951777
Lead Sponsor
Hope Biosciences
Brief Summary

The global objective of this study is to establish the safety and investigate the potential treatment effect of an intravenous infusion of HB-adMSCs (Hope Biosciences adipose-derived mesenchymal stem cells) on brain structure, neurocognitive/functional outcomes, and neuroinflammation after traumatic brain injury.

Detailed Description

This study is a prospective, randomized, double-blind, placebo-controlled Phase 2a study of three infusions of autologous HB-adMSCs (Hope Biosciences adipose-derived mesenchymal stem cells) (2 x 10\^8 total cells per dose) administered over a 6 week period with 14 day intervals between infusions. Subjects will be monitored and assessed for infusion related toxicity for at least 1 hour after the infusion and by telephone 24hr. after each infusion. Safety assessments will be conducted at the study follow-up clinic visits 6 and 12 months, and 2 years (telephone call) after the last HB-adMSC (Hope Biosciences adipose-derived mesenchymal stem cells) infusion, or more frequently if infusion related adverse events are suspected.

Brief Symptom Inventory 18Baseline, change from baseline at 6 months post-infusion, change from baseline at 1 year post-infusion

Brief Symptom Inventory with 18 items contains three six-item scales for somatization, anxiety, depression, and the global Scale Global Severity Index (GSI). Each item is scored either 0 (Not at all), 1 (A little bit), 2 (Moderately), 3 (Quite a bit), 4 (Extremely), or R (Refused).

The GSI therefore ranges between 0 (minimum) - 72 (maximum) and the three scales range between 0 (minimum) - 24 (maximum).

Higher scores indicate worse outcome.

Wechsler Adult Intelligence Scale - IV: Processing Speed IndexBaseline, change from baseline at 6 months post-infusion, change from baseline at 1 year post-infusion

Information processing rate on paper-pencil tasks requiring visual attention. It is composed of 10 core subtests and five supplemental subtests, with the 10 core subtests comprising the Full Scale IQ.

There are four index scores representing major components of intelligence: Verbal Comprehension Index (VCI); Perceptual Reasoning Index (PRI); Working Memory Index (WMI); Processing Speed Index (PSI)

Two broad scores are also generated, which can be used to summarize general intellectual abilities: Full Scale IQ (FSIQ), based on the total combined performance of the VCI, PRI, WMI, and PSI; General Ability Index (GAI), based only on the six subtests that comprise the VCI and PRI

The range of possible WAIS-IV (Wechsler Adult Intelligence Scale - IV) full scale IQs is 45-155. The WAIS-IV computes scaled scores for each individual based exclusively on chronological age.

Higher score indicates better outcome.
