Mořské lipidy zmírňují bolestivé TMD (ADAPT)
Bezpečnost a analgetická účinnost mořských lipidových prekurzorů specializovaných pro-řešicích mediátorů u dospělých s chronickou temporomandibulární bolestí
The ADAPT study is a single-site, Phase 2b, randomized, quadruple-masked, placebo-controlled trial evaluating an omega-3 dietary supplement enriched with specialized pro-resolving mediator (SPM) precursors in adults with chronic temporomandibular disorder (TMD) pain. The trial will enroll 100 adults aged 18 years or older with examiner-confirmed TMD myalgia or arthralgia will be enrolled at the University of North Carolina at Chapel Hill, Adams School of Dentistry.
Participants are randomized 1:1 to receive either the SPM precursor supplement or a matched placebo daily for 8 weeks. Randomization is stratified by sex, and study agents are identical in appearance to maintain masking.
The study aims to evaluate whether the SPM precursor supplement:
Reduces facial pain intensity compared with placebo.
Changes pressure pain sensitivity at the jaw and other standard body sites.
Affects other aspects of chronic pain, including duration, interference with daily activities, headache burden, anxiety, depression, jaw-related quality of life, and overall patient-reported change.
Participants will record their daily facial pain intensity in paper diaries, complete short questionnaires at baseline, Week 4, and Week 8, and undergo experimental pain testing with a handheld algometer at baseline, Week 4, and Week 8. Safety is monitored through the documentation of all adverse events throughout the study period.

Daily Diaries: Participants record facial pain intensity (0-100 NRS) each day for 8 weeks.
Mid-study Assessment (Week 4, Visit 2): Questionnaires for pain, mood, quality of life; pressure pain threshold testing.
Final Visit (Week 8, Visit 3): Repeat questionnaires, pressure pain testing, and body manikin assessments; blood collection for polyunsaturated fatty acid (PUFA)/oxylipin analysis.
Follow-up Call (1 week post-intervention): Safety check for adverse events.
Study Duration
Total participation: up to 12 weeks (pre-screening, 8-week intervention, 1-week follow-up).
Assessments at baseline, Week 4, Week 8, and follow-up call.
Population and Recruitment Adults ≥18 years with examiner-confirmed TMD myalgia or arthralgia. Participants of all races and ethnicities are eligible; anticipated demographics: ~77% female, 6% Hispanic, 83% White, 8% African American, 9% other.
Overall Goal To provide high-quality evidence on the effects of omega-3 SPM precursors on facial pain, pressure pain sensitivity, psychosocial distress, headache burden, jaw-related quality of life.

Experimentální: SPM precursor marine lipid dietary supplement
Experimental Arm - SPM Precursor Marine Lipid Supplement: Participants receive 2 g/day (1 g twice daily) of SPM Active® softgels containing 18-HEPE, 17-HDHA, and 14-HDHA. Softgels are identical in appearance to placebo. Duration: 8 weeks. Placebo Arm - Medium-Chain Triglyceride (MCT) Supplement: Participants receive 2 g/day (1 g twice daily) of MCT oil softgels, identical in appearance to active supplement. Duration: 8 weeks. |
Participants receive omega-3 SPM precursor-enriched marine lipid softgels administered daily for 8 weeks at the dose specified in the protocol. |
|
Komparátor placeba: Medium-chain triglyceride dietary supplement
Participants receive 2 grams per day of a placebo supplement, administered as medium-chain triglyceride (MCT) oil softgels. Participants take 1 gram orally twice daily for 8 weeks. The placebo softgels are identical in appearance and packaging to the active supplement. Participants remain in this arm for the full duration of the study. |
