Lignosus Rhinoceros TM02® as a Complementary Therapy for Uncontrolled Asthma

This 90-day prospective phase II, open label, single-arm study was conducted from March 2022 to February 2023. Subjects with partially controlled or uncontrolled asthma, assessed according to the Global Initiative for Asthma (GINA) guidelines, were enrolled from the outpatient asthma clinic at the Universiti Malaya Medical Centre, Kuala Lumpur, Malaysia. The effects of TM02® on bronchodilation was determined via trough forced expiratory volume in 1 second (FEV1) assessment. Improvement of asthma control was assessed using the Asthma Control Questionnaire-7 (ACQ-7). Serial measurements of fractional exhaled nitric oxide (FeNO) levels at baseline, 30, 60 and 90 days were performed to assess the effectiveness of TM02® in reducing FeNO, a marker of Type 2 airway inflammation. Blood eosinophil count and serum immunoglobulin E (IgE) level were also measured.
