Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of the treatment with Bromelain tablets in COVID-19 positive patients is to assess the change in Patient reported symptoms.;Secondary Objective: Secondary objectives of the Trial are: - to assess the Clinical improvement of the Patient Status via a WHO ordinal scale - to assess the Clinical improvement of the Patient state via measurement of Body temperature and blood Oxygen Saturation - to assess the Clinical improvement of the Patient state via measurement of blood Parameters - to assess the Clinical improvement of the Patient state via measurement of Virus load in nasopharyngeal swabs (Ct values) - to assess the clincal Impact of the Treatment with Bromelain tablets with regards to Quality of Life ;Primary end point(s): Primary endpoint of the efficacy of Bromelain tablets in COVID-positive patients is the baseline-adjusted course of the median of Symptoms (anosmia, ageusia, fever, cough, sore throat, shortness of breath, coryza, general weakness, headache, aching limbs, loss of appetite, nausea, abdominal pain, vomiting, diarrhoea, conjunctivitis, rash, lymph node swelling, apathy, somnolence) documented over the course of the study (day 1 - day 11). ;Timepoint(s) of evaluation of this end point: COVID-19 symptom severity will be assessed daily (day 1 to day 11).

Secondary

MeasureTime frame
Secondary end point(s): 1. baseline-adjusted area under the curve of the total symptom score 2. baseline-adjusted area under the curve of each individual symptom 3. proportion of patients who show a decrease in their baseline-adjusted symptoms score of SARS-CoV-2 within 3 days of treatment 4. change in patient status via measurement of virus load in nasopharyngeal swabs (Ct value at baseline V1 (D1) vs. Ct-values at V2 (D4 +/- 1 day), V3 (D7 +/- 1 day) and V4 (D11 +/- 2 days)). 5. proportion of patients with the presence of a positive PCR-test at V4 (D11 +/- 2 days) (virus load in nasopharyngeal swabs) 6. change in patient status using a 11-category ordinal score as proposed by the WHO 7. baseline-adjusted change in patient status by measurement of temperature (fever) and oxygen saturation of the blood 8. baseline-adjusted Change in patient status via measurement of blood parameters 9. baseline-adjusted change in quality of life as assessed by the SF-36 generic quality of life questionnaire. 10. Treatment emergent adverse Events and adverse drug reactions ;Timepoint(s) of evaluation of this end point: 1) baseline-adjusted area under the curve (day 1 - day 11) 2) baseline-adjusted area under the curve (day 1 - day 11) 3) V2 (D4 +/- 1 day) 4) V1, V2, V4 and V4 5) V4 6) V1, V2, V3, V4, V5, V6 7) V1, V2, V3, V4 8) V1, V2, V3, V4 9) V1, V2, V3, V4 10) over the entire study period (V1 - V6)
