Effect and Tolerance of Standardized Exclusive Dry Extracts of Curcuma Longa and of Boswellia Serrata Among People With Hand Joint Discomfort and Dysfunction (CUBO)
Effect and Tolerance of Standardized Exclusive Dry Extracts of Curcuma Longa (CURTIL03) and of Boswellia Serrata (BOSTIL01) in Support of Standard Treatments Among People With Hand Joint Discomfort and Dysfunction: a Multicenter Hospital Setting, Randomized, Blinded, Placebo-controlled Clinical Study.
The objective of the study is to evaluate the effect and tolerance of standardized exclusive dry extracts of Curcuma longa (CURTIL03) and of Boswellia serrata (BOSTIL01) among people with hand joint discomfort and dysfunction.
The study is prospective, randomized, double-blinded, placebo-controlled with 2 parallel-groups in 200 participants. The study is multicentric and will be done by 11 investigators located in Belgium including rheumatologists, sports and rehabilitation physicians, physical therapists, or any hand articular disease specialists.

Detailed Description
200 adult subjects suffering from significant hand joint discomfort will be randomized per site in 2 parallel groups (100 subjects per group).
Each patient will be enrolled in the study for 3 months including 3 visits: Inclusion/Baseline visit (V0), follow-up visits after 1 month (V1) and 3 months (V2).
A-PRIMARY OBJECTIVE Evaluate the effect of the association of standardized exclusive dry extracts of Curcuma longa CURTIL03 and Boswellia serrata BOSTIL01 versus placebo on the fingers pain after 3 months supplementation.
B-SECONDARY OBJECTIVES
Evaluate:
- finger pain on both hands at 1 month (mean and AUC) and 3 months (AUC)
- Functional disability at any timepoint (self-administrate questionnaire)
- Participant Global Assessment (PGA) at any timepoint
- To evaluate Minimum Clinically Important Improvement (MCII)
- To calculate Participant Acceptable important Symptom State (PASS)
- Consumption of rescue treatment (Paracetamol and oral NSAIDS) for hand pain at any timepoint
- Tender and swollen joints at any timepoint
- Grip strength at any timepoint
- Quality of life (e.g. including mood, sleep, disability) at any timepoint
- Tolerance to the product at 1 and 3 months
- Compliance to the product at 1 and 3 months
- Responder to supplementation at 1 and 3 months
EXPLORATIVE OBJECTIVES
• Evaluate the blood level of cartilage catabolism and inflammatory biomarkers before and after 3 months of supplementation.

Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Body Mass Index ≤ 35 kg/m2
Subjects that fulfil the following American College of Rheumatology (ACR) clinical criteria :
- Hand pain, aching, or stiffness AND
3 or 4 of the following features:
- Hard tissue enlargement of 2 or more of 10 selected joints,
- Hard tissue enlargement of 2 or more Distal interphalangeal (DIP) joints,
- Fewer than three swollen metacarpophalangeal (MCP) joints,
- Deformity of at least 1 of 10 selected hand joints.
The 10 selected joints are the second and third Distal Interphalangeal joint (DIP), the second and third Proximal Interphalangeal joints (PIP), and the first carpometacarpal (CMC) joints of both hands.
- Pain in hands at least half of the days in the previous month and for at least 48 h prior to the inclusion/baseline visit.
- Finger pain score of 40-80 mm on a 100 mm Visual Analog Scale (VAS) on at least one hand over the last 24 hours. Subjects should respect a 24-hours wash-out period of authorized analgesic/anti-inflammatory medications (Paracetamol/oral NSAIDs) before the visit.
- Willing to use only Paracetamol and oral NSAIDS as rescue treatment to manage hand pain during the study. Others analgesics and anti-inflammatory medication (oral and topic) are not allowed during the study and a wash out period of 5 half-life depending of the molecule should be respected before study entry.
- Able to follow the instructions of the study
- Having signed an informed consent
Exclusion Criteria:
Subjects that meet AT LEAST one of the following criteria will be excluded:
Related to hand

- Oral corticotherapy ≥ 5mg/day (in Prednisolone equivalent) in the last 3 months
- Allergy or contra-indication to the studied product or any ingredient present in this product or in placebo. Attention to medication interaction, see section on prohibited treatments
