New version of fabry drug tested against Brand-Name in healthy volunteers
NCT ID NCT05343715
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tested whether a new version of the enzyme replacement drug agalsidase beta (made by Biosidus) works similarly to the approved drug Fabrazyme. Twenty-four healthy men received a single infusion of one of the two drugs. Researchers measured how the drug moved through the body and its enzyme activity to see if the new version could be a potential alternative for treating Fabry disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- agalsidase beta (enzyme replacement therapy)
- What this could lead to
- If the new formulation works similarly to Fabrazyme, it could offer an alternative treatment option for Fabry disease.
- What could go wrong
- This is a very early, small study in healthy volunteers, not Fabry patients. It only tests a single dose, so it cannot predict long-term safety or effectiveness.

Inclusion Criteria: 1. Male subjects between the ages of 18 and 40 2. Body mass index (BMI) between 19 and 25 kg/m². 3. Volunteers whose complementary exams (ECG, chest X-ray, blood and urine, PCR for COVID-19), performed prior to their inclusion are within the normal range and/or are not clinically significant according to the investigator's judgement. 4. Subjects with systolic blood pressure higher than 110 mmHg and lower than 139 mmHg, diastolic blood pressure higher than 70 mmHg and lower than 89 mmHg with a heart rate higher than 50 and lower than 90 beats per minute after being seated for 5 minutes and, then, standing up (extreme values are included) 5. Volunteers who are well disposed to the study and have signed the approved informed consent prior to the start of the study Exclusion Criteria: 1. History of clinically significant allergies (except for untreated asymptomatic seasonal allergies) 2. A drop of ≥ 20 mmHg of systolic blood pressure or ≥ 10 mmHg of diastolic blood pressure within the first 3 minutes after the postural change 3. Volunteers who are receiving other drugs (prescription or over-the-counter) or who have within the 2 weeks prior to the study 4. Volunteers with history of autoimmune diseases. 5. Chronic disorders of the CNS, psychological and/or psychiatric disorders: bipolar disorder, severe depression, insomnia, changes in personality 6. Active or chronic infections 7. Having received live or inactivated viral or bacterial vaccines, within the fifteen days prior to visits 1 or 2 8. For COVID vaccines, a 15 day window period prior to visits #1 or #2 must be respected. This period was taken from the recommendations published by the National Ministry of Health on May 29th 2021. The volunteer will be able to receive the vaccine 35 days after receiving the investigational product. 9. Known allergies to any of the components of the formulations 10. Active smoker, of more than 10 cigarettes/day 11. Current clinical evidence of severe digestive disorders, surgeries of the gastrointestinal tract (except for appendectomy) 12. Current clinical evidence of kidney disease 13. Current clinical evidence of liver disorders 14. Current clinical evidence of respiratory and cardiac disease 15. Presence of diabetes mellitus, thyroid dysfunction or other endocrine disorders 16. Evidence of active gastroduodenal disease 17. History of peripheral thrombotic phenomena 18. Underlying neurological disease 19. Presence of a current progressive chronic disease 20. History of drug or alcohol abuse or addiction within the last three years 21. Participation in a clinical study within the last three months 22. Use of any drug within the fourteen days prior to the start of the study that, according to the principal investigator's judgement may interfere with the biodistribution of the medicinal product. 23. Subjects who have donated or suffered from blood loss within the twelve weeks prior to the start of the study, or intends to donate blood within the following three months after the completion of the study. 24. Excessive drinker of tea, cocoa, mate, coffee and/or caffeinated drinks (\>5 cups/day) or of wine (\>0.5 L/day) or alcohol (\>50 ml/day) 25. Significant abnormalities in the electrocardiogram 26. Positive PCR test for COVID-19 27. Positive serology for HIV, hepatitis B or hepatitis C 28. Abnormal clinical laboratory test results (that according to the principal investigator's judgement are considered clinically significant) 29. Uncooperative volunteers
