Brief Summary

Cordyceps is a medicinal Chinese medicine. The benefits of cordyceps-related therapeutic action have been studied due to its anti-inflammation and immunomodulation features. Thus, Cordyceps may have efficacy against health problems in the post-COVID era. the Cs4 is a Chinese medicine nutritional supplement fermented by Cordyceps. This Project conducts a two-stage waitlist-controlled trial to examine the therapeutic effect of the Cs4 on long-COVID patients. 110 Patients will be recruited and divided into two groups. Each group contains 55 patients. In the first-stage clinical trial for 12 weeks, group A will have treatment while group B will have no Cs4 treatment. In the second-stage clinical trial for 12 weeks, group A will have no Cs4 treatment while group B will have Cs4 treatment. A 12-week follow-up will be conducted after the intervention of Cs4 for group A. The primary outcome will be the change from 0 to 12 weeks in symptom severity measured by self-declared modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm). In our study, we intend to analyse the efficacy of Cs4 on the improvement of long Covid symptoms by using a comprehensive measurement to cover most symptoms, and be condition-specific. The secondary outcomes will include the change from 0 to 12 weeks of Insomnia Severity Index (ISI), Brief Fatigue Inventory Form, St. George's Respiratory Questionnaire (SGRQ), Hospital Anxiety and Depression Scale (HADS), and the Short Form 12 (SF12). Blood tests will be assessed for safety study. primary outcomes and secondary outcomes will be assessed at baseline (week 0) and week 12. The anticipated outcome of the study is to provide evidence of Cs4 in the improvement of long COVID symptoms. This project can serve to the development of a nutritional supplement for the management of post-COVID-related health problems.

Outcome Measures

Primary Outcomes (1)

  • the change in symptom severity from 0 to 12 weeks measured by the modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm)

    Symptom severity is one of the sub-scale of C19-YRSm. Range 0-78, with higher scores indicating greater impact of symptoms. C19-YRSm is the first validated scale describing post-COVID-19 symptoms and grading the severity of symptoms and functional disability.

    will be assessed at baseline and 12 weeks.

Secondary Outcomes (5)

  • the change in Insomnia Severity Index (ISI) from 0 to 12 weeks

    will be assessed at baseline and 12 weeks.

  • the change in Brief Fatigue Inventory Form (BFI) from 0 to 12 weeks

    will be assessed at baseline and 12 weeks.

  • the change in St. George's Respiratory Questionnaire (SGRQ) from 0 to 12 weeks

    will be assessed at baseline and 12 weeks.

  • the change in Hospital Anxiety and Depression Scale (HADS) from 0 to 12 weeks

    will be assessed at baseline and 12 weeks.

  • the change in Short Form 12 (SF12) from 0 to 12 weeks

    will be assessed at baseline and 12 weeks.

Interventions

Cs4 will be provided by Chinese Pharm, produced by GMP standard manufacturing. The intervention will be given according to the product instruction. Each capsule is 0.4g. According to the product sheet, adults should take 3-4 capsules daily as a way to nourish and strengthen the lungs and kidneys. In our study, the participants are people with long-COVID symptoms. Therefore, in order to achieve maximum efficacy, we will follow the directions and let participants take the maximum amount allowed by the product which is 4 capsules daily. Participants will take one capsule (each 400mg) 4 times a day, for a total of 1.6g. Treatment will last 12 weeks.
