the best trial: biomarkers for evaluating spine treatments

Conditions: Chronic Low-back Pain

Summary: the best trial (biomarkers for evaluating spine treatments) is a niams-sponsored clinical trial being conducted through the nih heal initiative's back pain consortium (bacpac) research program. the primary objective of this trial is to inform a precision medicine approach to the treatment of chronic low-back pain by estimating the optimal treatment or combination of treatments based on patient features and response to the initial treatment. interventions being evaluated in this trial are: (1) enhanced self-care (esc), (2) acceptance and commitment therapy (act), (3) evidence-based exercise and manual therapy (ebem), and (4) duloxetine.

each participant will complete an initial screening call and enrollment visit, followed by a 2-week run-in period, two consecutive 12-week treatment periods, and a 12-week post-treatment follow-up period. upon completion of the run-in period, participant eligibility will be reassessed based on adherence to study protocol. participants who no longer meet eligibility criteria will be considered screen failures and discontinued from the study. all participants will undergo phenotyping assessments at visit 0, 1 and 2 corresponding to baseline, the end of the first 12-week intervention period, and the end of the second 12-week intervention period, respectively. a subset of participants will undergo additional phenotyping, consisting of a more comprehensive set of phenotyping assessments, at the same visits. pain, enjoyment of life, and general activity (peg) and patient global impressions scale (pgic) will be assessed at 6 weeks (midpoint of intervention period one), 12 weeks (visit 1), 18 weeks (midpoint of intervention period two), 24 weeks (visit 2), and 36 weeks post-baseline (12 weeks after intervention period two). basic safety assessments will also be performed at these time points to assess participant tolerability to their current study intervention(s). patients who are unable to tolerate their assigned study treatment will be educated on how to safely discontinue their current treatment plan but will otherwise remain in the study.
