Cs4 for Pneumoconiosis Rehabilitation

6 novembre 2026 aggiornato da: Tung Leong FONG

Efficacy and Safety of Cordyceps Sinensis Mycelium Culture Extract (Cs4) Supplementation in Pneumoconiosis Rehabilitation: a Randomized, Controlled Trial

This clinical trial will test whether a Cordyceps supplement improves lung function. The supplement is called Cordyceps sinensis mycelium Culture extract (Cs4). The study will include adults with pneumoconiosis, a lung disease caused by breathing in mineral dust. Researchers will also assess Cs4 safety.

The main questions are: (1) does Cs4 improve lung function compared with a placebo? (2) what health problems occur while participants take Cs4?

The study will include 84 adults aged 18 to 75 years. Their breathing condition must have been stable for at least three months. The study will take place at the School of Chinese Medicine, The University of Hong Kong.

Researchers will compare Cs4 with a placebo, a look-alike capsule containing no Cs4. Chance will determine which capsules each participant receives. Each participant has an equal chance of joining either group. Participants and researchers who assess them will not know which capsules participants receive.

Participants will: (1) take two capsules of Cs4 or placebo twice daily for 24 weeks; (2) record the capsules they take each day and return unused capsules at study visits; (3) attend clinic visits for breathing tests, a walking test, and blood tests; (4)answer questions about their breathing symptoms and daily life. (5) continue follow-up visits for 12 weeks after finishing the capsules.

Descrizione

Inclusion Criteria: (1) adults aged 18-75 years; (2) diagnosed with pneumoconiosis based on clinical and radiological criteria, including chest X-ray/computed tomography and International Labour Organization (ILO) classification; (3)stable respiratory condition for at least 3 months before enrollment, with no acute exacerbations, hospitalizations, or changes in respiratory medication; (4)able to provide written informed consent.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Cs4 supplementation

Participants will receive Cordyceps sinensis mycelium culture extract (Cs4) orally at 1.6 g per day, administered as two 0.4 g capsules twice daily for 24 weeks, followed by 12 weeks of follow-up.

Cordyceps sinensis Mycelium Culture Extract (Cs4) is a fermented mycelial preparation of Cordyceps sinensis, a fungus used in Traditional Chinese Medicine. It is produced by cultivating and fermenting the mycelium, the vegetative part of the fungus. In this trial, Cs4 is used as a dietary supplement to investigate its effects on lung function and rehabilitation outcomes in adults with pneumoconiosis.

Comparatore placebo: Matching placebo

Participants will receive matching placebo orally, administered as two capsules twice daily for 24 weeks, followed by 12 weeks of follow-up. Placebo capsules will contain starch, sucrose, and food-grade colorants and will match Cs4 capsules in size, color, weight, smell, and packaging.

Matching placebo capsules containing starch, sucrose, and food-grade colorants, with no Cs4 extract. The placebo capsules will match the Cs4 capsules in size, color, weight, and smell and will be supplied in identical blister packs to maintain blinding. Participants will take two capsules orally twice daily for 24 weeks.
