Study summary

The purpose of the chronic pain master protocol is to compare independent pain interventions and establish an overarching structure for the disease-state addenda (DSA) and intervention-specific appendices (ISAs). The ISAs may start independently of other ISAs as interventions become available for clinical testing.

Read the detailed description

The chronic pain master protocol (CPMP) establishes entry criteria and includes DSA for osteoarthritis of the knee, chronic low back pain, and diabetic peripheral neuropathic pain. The DSA have specific study elements to appropriately define the target population and unique scales for assessment. Also, the master protocol governs ISAs that may start independently of other ISAs as interventions become available for clinical testing.

Note: Results for all outcomes are posted in the intervention records. No need for duplication.

Inclusion criteria

  • have a visual analog scale (VAS) pain value ≥40 and \<95 at screening and prerandomization screening.
  • have a history of daily pain for at least 12 weeks based on participant report or medical history
  • have a value of ≤30 on the pain catastrophizing scale
  • are willing to maintain a consistent regimen of any ongoing nonpharmacologic pain-relieving therapies (for example, physical therapy) and/or nutritional supplements and will not start any new nonpharmacologic pain-relieving therapies and/or nutritional supplements during study participation
  • are willing to discontinue all medications taken for chronic pain conditions, except rescue medication for the duration of the study

Exclusion criteria

Exclusion Criteria:

  • have second- or third-degree atrioventricular (AV) heart block or AV dissociation or history of ventricular tachycardia
  • have had a procedure within the past 6 months intended to produce permanent sensory loss in the target area of interest (for example, ablation techniques)
  • have surgery planned during the study for any reason, related or not to the disease state under evaluation.
  • have, in the judgment of the investigator, an acute, serious, or unstable medical condition or a history or presence of any other medical illness that would preclude study participation.
  • have had cancer within 2 years of baseline, except for cutaneous basal cell or squamous cell carcinoma resolved by excision.
  • have fibromyalgia
  • have any abnormality at screening, as determined by investigator, in physical or neurological examination, vital signs, (ECG), or clinical laboratory test results that could be detrimental to the participant or could compromise the study.
  • have a positive (HIV) test result at screening
  • have a history of alcohol, illicit drug, analgesic or narcotic use disorder within 2 years prior to screening.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
