Study to Investigate Improvement in Physical Function in SF-36 With Vericiguat Compared With Placebo in Participants With Post-COVID-19 Syndrome

The goal of this clinical trial is to evaluate the therapeutic value of an approved drug (Vericiguat) in patients with post-COVID-19 syndrome, who suffer from profound tiredness or fatigue, regardless of bed rest.The main questions it aims to answer are: • Does Vericiguat relieve fatigue and/or other symptoms associated with post-COVID-19 syndrome? • What are the side effects of Vericiguat in this patient population; and how common are they? Participants will be asked to participate for approx. 18 weeks. After screening, participants will receive assigned intervention of either 10 weeks of treatment with Vericiguat or matching placebo tablet, followed by 30 day follow-up period. Every participant will undergo trial, cardiovascular safety, and monitoring assessments. The results of this study will provide information on whether Vericiguat can alleviate PCS-related symptoms as well as insights into the pathophysiological processes of PCS, which in turn can help to develop therapies.

Hyperbaric High Pressure Oxygen Therapy in Post-COVID Syndrome and ME/CFS

The objective of this observational study is to document symptom progression in 60 patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) who undergo Hyperbaric Oxygen Therapy (HBOT) following COVID or other infections. Participants will receive HBOT treatment as an additional option after completing the Chronic Fatigue Syndrome CARE (CFS\_CARE) study and will be invited to take part in this observational study. Patients will complete health evaluations in the form of questionnaires, including the 36-Item Short Form Health Survey (SF-36), to assess changes in ME/CFS-related symptoms after HBOT. Rather than evaluating the efficacy of HBOT itself, the study will focus on observing and documenting these changes. Its goal is to offer valuable insights into symptom progression in ME/CFS patients receiving HBOT, which can serve as a foundation for future interventional randomized controlled trials.

RCT of Efficacy and Safety of CP003 on CFS/ME or Post-COVID Fatigue

The goal of this clinical trial is to test if a Lingzhi supplement (CP003) helps people with chronic fatigue or post-COVID fatigue feel better. It will also check if the supplement is safe to use. The main questions it aims to answer are: Does the Lingzhi supplement reduce fatigue symptoms? Is it safe to take? How does it affect the body's immune system and inflammation? Researchers will compare people taking the Lingzhi supplement to those who don't take anything (waitlist group) to see if it works. Participants will: * Take 5 capsules once daily for 6 weeks (or wait to start treatment if in waitlist group) * Visit the clinic 2 times for blood tests (before and after taking the supplement) * Complete questionnaires 3 times about their fatigue and quality of life (4 times questionnaires for waitlist group)
