    Reproductive system

  27. Pregnancy.
  28. Planned pregnancy within the study period, 3 months after end of study treatment for female fertile participant and 6 months after end of study treatment for male participant.
  29. Insufficient anti-conception therapy for female fertile participants within the study period and 3 months after end of study treatment. Sufficient anti-conception therapy consists of intra-uterine device (coil),hormonal anti-conception (birth control pills, implant, intra-uterine system, dermal patch, vaginal ring, or injections) or sexual abstinence Female participants are considered infertile if they are postmenopausal or if they have undergone surgical sterilisation (bilateral salpingectomy, hysterectomy or bilateral oophorectomy). Postmenopausal state is defined as no menses for 12 months without alternative medical cause before inclusion in the study. Menopause state will be confirmed by measurement of follicle stimulating hormone.
  30. Insufficient anti-conception therapy for male participants within the study period and 6 months after end of study treatment. Sufficient anti-conception therapy consists of condom or sexual abstinence. Male participants are considered sterile if they have undergone surgical sterilisation (vasectomy).
  31. Breast-feeding

A target hand will be selected for outcome assessment once individual fulfills in- and exclusions criterias. Selection of the target hand will adhere to the following, with advancement to next step if unable to choose target hand based on the given criteria.

  1. The hand with most overall pain, assessed by VAS finger joint pain.
  2. The hand with most overall reduced function, assessed by AUSCAN function subscale.
  3. The hand with most overall stiffness, assessed by AUSCAN stiffness subscale.
  4. The hand with most swollen joints, assessed by physician joint count.
  5. The hand with most tender joints, assessed by physician joint count.
  6. The hand with highest summed radiographic score, assessed by radiographic scoring of conventional X-ray.
  7. If unable to select target hand based on the above criteria, a target hand will be randomly assigned.

What researchers measure

Primary outcomes

  1. Finger pain

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, on changes in finger joint pain of the target hand from baseline to week 12, in patients with painful hand OA measured on a visual analogue scale spanning from 0 to 100, where 0 equals no symptoms and 100 equals worst imaginable symptoms.

    Time frame: Week 12

Secondary outcomes

  1. Function

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, from baseline to week 12, in patients with painful hand OA on changes in function of both hands measured on the Australian/Canadian Hand Index Function Score spanning from 0 to 900, where higher scores equals worse function.

    Time frame: Week 12

  2. Thumb base pain

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, from baseline to week 12, in patients with painful hand OA on changes in thumb base pain of the target hand measured on a visual analogue scale spanning from 0 to 100, where 0 equals no symptoms and 100 equals worst imaginable symptoms.

    Time frame: Week 12

  3. Pain hands

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, from baseline to week 12, in patients with painful hand OA on changes in pain of both hands measured on the Australian/Canadian Hand Index Pain Score spanning from 0 to 500, where higher scores equals worse pain.

    Time frame: Week 12

  4. Joint activity

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, from baseline to week 12, in patients with painful hand OA on changes in joint activity of the target hand measured on physician tender joint count

    Time frame: Week 12

  5. Patient global assessment

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, from baseline to week 12, in patients with painful hand OA on changes in patient global assessment measured on a visual analogue scale spanning from 0 to 100, where 0 equals no symptoms and 100 equals worst imaginable symptoms.

    Time frame: Week 12

  6. Quality of life measured by European Quality of Life 5 Dimensions

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, from baseline to week 12, in patients with painful hand OA on changes in quality of life measured on the European Quality of Life 5 Dimensions spanning from -0.624 to 1.000, where higher scores equals better quality of life.

    Time frame: Week 12

  7. Hand strength

    To compare the effect of oral colchicine 0.5 mg bid, relative to placebo, from baseline to week 12, in patients with painful hand OA on changes in hand strength of the target hand measured on grippit

    Time frame: Week 12

  8. Number of treatment responders according to OMERACT-OARSI response criteria

    The following two conditions is observed at the post-baseline assessment: 1. In either pain (finger pain) or function (function), a high improvement in the subscale, where high improvement in a subscale is achieved if there is both a \> 50% improvement from Baseline and an absolute change from Baseline of \> 20 percent points (0-100 scale), OR 2. Improvement in at least two of the following three: * Improvement in pain (finger pain) defined as \> 20% improvement from Baseline and an absolute change from Baseline of \> 10 points (0-100 scale) * Improvement in function (function) defined as \> 20% improvement from Baseline and an absolute change from Baseline of \> 10 points (0-100 scale) * Improvement in patient's global assessment defined as \> 20% improvement from Baseline and an absolute change from Baseline of \> 10 mm (0-100 scale)

    Time frame: Week 12
