Summary
Pacing is tracked by OSMF as an investigational option for ME/CFS; no regulator has approved it for this indication, and most post-viral conditions have no approved disease-modifying therapy at all. ClinicalTrials.gov lists 1 registered trial linking Pacing to ME/CFS: 1 has completed. The most advanced is Phase 2 (NCT01512342, sponsored by Vrije Universiteit Brussel). It plans or enrolled 33 participants. Registered activity dates to 2011. No published literature item is linked to Pacing and ME/CFS in the OSMF database yet, so the record rests on registry entries alone. Registry entries describe intent to study, not outcomes.
Myalgic Encephalomyelitis / Chronic Fatigue Syndrome is tracked on the OSMF post-viral programme alongside ME/CFS, Long COVID, POTS and MCAS. Across the programme, 191 candidate agents are logged for ME/CFS, most of them preliminary; this page isolates the record for one of them.

How the evidence score is calculated
- Each registered trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5). The trial component is capped at 30.
- Each literature item scores by design (Cochrane review 5, meta-analysis 4, systematic review 3, RCT 3, clinical trial publication 2, curated reference 1.5, other PubMed record 1). The literature component is capped at 30.
- The existing evidence tier adds 15 (A / Strong), 10 (B / Moderate), 5 (C / Preliminary) or 0 (D / Anecdotal).
- Agents approved for any indication (max clinical phase 4) add 5, because an approved agent has an established safety profile that lowers the barrier to repurposing trials.
- The score ranks what has been studied, not what works. It does not read effect sizes or directions of effect.

Mechanism and notes
This is a behavioural, rehabilitation or protocol-based intervention rather than a molecule, so no pharmacological mechanism is recorded.
Clinical notes: Investigational for listed conditions. 1 associated trial(s) and 0 study reference(s) in current data. Review primary sources and consult specialists before use.
Safety: Limited specific safety data in these populations. Review full prescribing information and consult specialist. Many agents used off-label or investigational.
Dosing in studies: See linked studies/trials for reported doses and durations; typical protocols vary widely.
Frequently asked questions
Is Pacing approved for ME/CFS?
Pacing is tracked by OSMF as an investigational option for ME/CFS; no regulator has approved it for this indication, and most post-viral conditions have no approved disease-modifying therapy at all. Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Pacing in clinical trials for ME/CFS?
ClinicalTrials.gov lists 1 registered trial linking Pacing to ME/CFS: 1 has completed. The most advanced is Phase 2 (NCT01512342, sponsored by Vrije Universiteit Brussel). It plans or enrolled 33 participants. Registered activity dates to 2011.
What does the evidence show for Pacing in ME/CFS?
Pacing has 1 completed registered trial for ME/CFS but no linked publication, which usually means results are unpublished, pending, or not yet matched to this record. OSMF's existing evidence tier for this pair is C (Preliminary), taken from the OSMF therapeutic agent database, which grades agents by the volume and design of condition-specific evidence rather than by effect size.
