Trial design

Randomised, matching placebo control arms (placebo tablets identical to active minocycline tablets and relabelled identical to the study drug). active investigational arms include: metformin (oral; maximum daily dose listed as 1500 mg; max treatment period 12 weeks), colchicine (oral; maximum daily dose listed as 1 mg; max treatment period 12 weeks), minocycline (oral; maximum daily dose listed as 100 mg; max treatment period 16 weeks). exact day-to-day dosing schedules are not specified in the provided part 1/part 2 summary., adaptive Phase III trial across 1 site in Netherlands.

Yes
Comparator
Matching placebo control arms (placebo tablets identical to active minocycline tablets and relabelled identical to the study drug). Active investigational arms include: METFORMIN (oral; maximum daily dose listed as 1500 mg; max treatment period 12 weeks), COLCHICINE (oral; maximum daily dose listed as 1 mg; max treatment period 12 weeks), MINOCYCLINE (oral; maximum daily dose listed as 100 mg; max treatment period 16 weeks). Exact day-to-day dosing schedules are not specified in the provided Part 1/Part 2 summary.
Adaptive
True, includes platform/adaptive design elements: multiple treatment-specific domains (TSAs) and appendices, the ability to evaluate multiple IPs vs control within domains, and domain-specific randomisation rules described in the TSAs. Adaptive platform structure (RECLAIM) is explicit in the title and protocol groupings; specific dose-escalation rules or stopping rules are described in TSAs (not included verbatim here).

Inclusion criteria

  • {"criterion_text":"- Adults aged 18 years or older.\n- Residing in the study area (defined in each respective CSA) for the duration of trial participation.\n- Persistent PASC signs and symptoms, including fatigue and/or PEM, for a period of at least 12 weeks after the onset of a SARS-CoV-2 infection. The symptoms were not present prior to the infection, but may have partially subsided and resurged after the infection.\n- Self-reported confirmation of having had a SARS-CoV-2 infection by: a. Positive SARS-CoV-2 nucleic acid amplification test (NAAT), such as PCR; b. Positive SARS-CoV-2 rapid diagnostic test, including home-administered tests; c. COVID-19 diagnosis by a treating physician (GP or medical specialist), based on the above or other clinical tests and assessments. Alternatively, a treating physician may have diagnosed the patient with PASC, thereby implicitly acknowledging that the patient had COVID-19 in the past.\n- Willing and able to provide informed consent\n- Willing and able to perform trial procedures\n- Allowing their GP/pharmacy and the RECLAIM trial team to exchange medical information that is relevant for the participant’s safety and trial assessments."}

Exclusion criteria

  • {"criterion_text":"- Having been diagnosed with (exacerbation of) a chronic disease that can account for the onset of the PASC-like symptoms.\n- Being hospitalised or institutionalised at screening. Patients can be rescreened after discharge.\n- Presence of a serious medical condition that would prevent completion of follow-up.\n- Currently enrolled, or having been enrolled within the last 30 days, in any other study where that study’s interventions or procedures may affect RECLAIM outcomes or procedures. Individuals can be rescreened after at least 30 days have passed since participation in such a study has been completed.\n- Having initiated chronic use of a new licensed medication for any indication in the three months prior to the eligibility confirmation by a trial physician. This criterion may be reassessed after sufficient time has passed. Similarly, the potential participant should commit to not starting any chronic use of new licensed medications for any indication between eligibility confirmation and Week-12 unless medically necessary as determined by a treating physician (see section 8.1.1.1).\n- The following exclusion criteria will apply to all potential participants WITHIN ONE TRIAL DOMAIN (these patients may still qualify for another trial domain): 6 The participant cannot be randomised to at least one IP arm and its control arm within a trial domain due to (refer to relevant TSAs for details): a. Known hypersensitivity to an active IP ingredient or IP/placebo excipient; b. Receiving a treatment that is contraindicated to a trial IP; c. Already using a trial IP, or a drug in the same drug class as a trial IP, outside of the trial; d. Any other reason why a trial IP cannot be used, such as (risk of) pregnancy or breastfeeding or renal insufficiency."}
