Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male or female; age between 18 and 75 years.
  • Patient with symptomatic STT OA.
  • Patient treated medically for functional signs for more than 3 months, without improvement, justifying a surgical intervention.
  • Patient with a QuickDash score > 33 points (converted to 50%).
  • Patient with wrist pain in front of the STT joint at rest = or > 4/10 on VAS.
  • Patient who received the study information and provided consent.
  • Member or beneficiary of a national health insurance plan.

Exclusion Criteria:

  • Pregnant or breastfeeding woman; woman without effective contraception.
  • Patient with functional rhizarthrosis that has not been stabilized or treated medically or surgically.
  • Patient with signs of neuropathy with functional disorders such as hyperesthesia.
  • Patient with uncontrolled epilepsy or neuropathy that contraindicates locoregional anesthesia.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Decrease of the symptomatology related to the STT OA
Time Frame: 12 months
Quality of life related to STT OA evaluated using Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire (0 = no disability, 100 = most severe disability); a decrease of 25% of the score is expected between subject's inclusion and the 12-month postoperative visit
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
No apparent joint space anomaly
Time Frame: 12 months
Joint space evaluated on radiography using Crosby's classification
12 months
Absence of inflammatory reactions and good local tolerance of the implant
Time Frame: Through study completion (12 months)
No inflammatory reactions (oedema, erythema, necrosis, ulceration and/or delayed wound healing), no adverse effects or serious adverse effects.
Through study completion (12 months)
Decrease of pain related to STT OA
Time Frame: 1 month, 3 months, 6 months, 12 months
Pain evaluated from 0 (no pain) to 10 (worst imaginable pain) on a visual analog scale (VAS)
1 month, 3 months, 6 months, 12 months
Improvement of functional activities involving the thumb
Time Frame: 1 month, 3 months, 6 months, 12 months

1 month, 3 months, 6 months, 12 months
Increase of thumb strength
Time Frame: 3 months, 6 months, 12 months

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
