Hand Osteoarthritis
Conditions
Brief summary
PICASSO has been designed to demonstrate that combination therapy with CS/GH has superior efficacy compared to placebo in pain reduction (average score reduction in Huskisson's 0 to 100 mm Visual Analogue Scale) from baseline to 6 months of treatment in patients with symptomatic hand osteoarthritis.

Patients who present a Functional Index of Hand Osteoarthritis (FIHOA) score ≥ 6 at the screening visit; 9. Women of childbearing age (women whose last menstrual period was more than one year before study enrolment and those who have had tubal ligation or a hysterectomy performed are excluded) must have obtained a negative result for the pregnancy test conducted in the screening phase and must agree to use a medically acceptable contraceptive method throughout the duration of the study.

Patients must have a sufficient level of cognition to allow for proper communication and cooperation with all tests and examinations required in the protocol; 11.

Patients who are not participating in another clinical trial; 13. Patients who agree to respect the protocol, attending visits related to the study;
Exclusion criteria
1. Patients with isolated unilateral or bilateral rhizarthrosis only and/or radiological evidence of presence of erosive hand osteoarthritis (having just one erosive joint leads to classifying the patient as erosive). 2. Patients with a known allergy to CS or GH; 3. Patients with a seafood allergy; 4. Patients with a history of intolerance to paracetamol; 5. Patients with active malignancy of any type or with a history of malignancy in the last five years; 6. Patients who, in the investigator's judgement, do not have significant clinical alterations in their physical examination and laboratory parameters; 7. History of any condition which, in the investigator's opinion, could lead to misinterpretation of the study results or could pose an additional risk to the patient; 8. Concurrent articular rheumatism (history and/or current presence of signs) that could give rise to an erroneous interpretation of the efficacy on pain or which interfere in its assessment, such as carpal tunnel syndrome, Guyon's canal syndrome (involvement of cubital nervous), flexor tenosynovitis, trigger finger, chondrocalcinosis, , aseptic osteonecrosis, gout, septic arthritis, ochronosis, acromegaly, haemochromatosis, Wilson's disease, osteochondromatosis, rheumatoid arthritis, ankilosing spondylitis, psoriasis, inflammatory bowel disease, connective tissue disease, vasculitis, diabetic neuropathy, post-traumatic osteoarthritis of the finger; 9. Pain in other parts of the body more intense than in the hand, which could interfere with the assessment of the joint index; 10. Patients with fibromyalgia; 11. Patients with surgery scheduled during the clinical trial period; 12. Patients with important diseases or processes, such as psychological or psychiatric disorders or drug consumption which, in the investigator's opinion, is likely to alter the progress of the osteoarthritis or the patient's ability to complete the study; 13. Patients with poorly controlled diabetes mellitus defined as a level of haemoglobin A1c\> 8%; 14. Patients with poorly controlled hypertension (sustained systolic blood pressure ≥160 mm Hg or sustained diastolic blood pressure ≥100 mm Hg); 15. Patients with active acute or chronic infections that require antibiotic treatment, or serious fungal or viral infections (for example, hepatitis, herpes zoster, HIV positive); 16. Patients with chronic liver or kidney disease, defined by AST or ALT levels \> 2 times the upper limit of normal (ULN) or blood urea nitrogen (BUN) or serum creatinine levels \> 2 times the ULN at the inclusion visit; 17. Patients with a history of alcohol or drug consumption or abuse in the last 3 years; 18. Patients who have received any investigational drug in the 30 days prior to the screening visit; 19. Women who are breastfeeding; Treatment-related
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Huskisson's VAS | 6 months | Huskisson's Visual Analogue Scale of pain. Score Range: 0 (no pain) - 100 (maximum pain) The study was designed such that the outcome of primary interest is hand pain related to OA. The measure selected to best evaluate this is an improvement in the VAS pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in grip strength | 6 months | Grip strength in the study hand of the patient will be measured with a dynamometer. Patients sitting up in a chair supporting straight his/her back, in a position that allows hips and knees are at right angles; They flex the elbow at 90 ° between pronation and supination. Patients will be asked to squeeze the dynamometer as strong as they could according to their individual pain limits. This procedure will be repeated 3 times, with a break of 10 seconds between each of the measurements. The average value of these 3 measurements will be registered as the value for the parameter in the study. |
| Duration of morning stiffness | 6 months | The time in minutes that it took from the patient waking up in the morning until they felt that joint stiffness in the hand had diminished significantly. |
| Patient's global assessment of disease activity | 6 months | Patients were asked to quantify their disease status on a VAS scale with range 0 mm (best) and 100 mm (worst) as follows: Considering all the ways your arthritis of the knee affects you, mark (I) on the scale how well you are doing. Left hand marker Very Well, Right hand marked Very Poor. |
| FIHOA Index | 6 months | The FIHOA Index is a semi-quantitative questionnaire administered by the doctor or self-administered by the patient. If necessary, it is the questionnaire can be hetero-administered; investigator can assist the patient in understanding and completing the FIHOA. The questionnaire consists of 10 questions that score between 0 and 3 points (total range of 0-30) assessing the dexterity of the patient suffering from symptomatic Hand Osteoarhritis. |
| EuroQoL-5D | 6 months | EuroQoL-5D was a standardized instrument for use as a measure of health outcome that provides a simple descriptive profile and a single index value for health status. It was assessed at all of the study visits. The EQ-5D-3L essentially consists of 2 pages - the EQ-5D descriptive system (page 2) and the EQ visual analogue scale (EQ VAS) (page 3). The EQ-5D-3L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, extreme problems. Total scale range for each dimension reported is 1 to 3. The EQ VAS records the respondent's self-rated health on a vertical, visual analogue scale where the endpoints are labelled 'Best imaginable health state' and 'Worst imaginable health state'. This information can be used as a quantitative measure of health outcome as judged by the individual respondents. Total scale range for VAS dimension reported is 0 to 100. |
| HAD scale | 6 months | The Hospital Anxiety and Depression (HAD) questionnaire aims to determine the emotional state of the patient, as the importance of emotional factors is well-recognised in the majority of diseases. It consists of 14 items, and each item is assigned a score of 0, 1, 2 or 3. The scores are added together and between 0 and 7 means there is no case, between 8 and 10 is a borderline case and scores above 11 are, likely, cases in each one of the sub-scales |
| Consumption of Rescue Medication | 6 months | Use of rescue medication as number of paracetamol tablets 500 mg since the last visit. The tablet count was reconciled with the patient diary. Total Number of pills per month |
| Patient's global assessment of response to treatment | 6 months | The patient will be asked to score the overall response to the study drug in the hand, placing a vertical line (\|) on a 100 mm VAS in the following way: If they mark the left edge (0 mm), it means none, poor response, ineffective and if they mark on the right edge (100 mm), it means excellent, ideal response, virtually pain-free. |
