Clinical trials have proven that Xenpozyme® Improved lung operate and decreased spleen and liver quantity in adults and youngsters
The ASCEND examine evaluated the efficacy and security of Xenpozyme®; 36 grownup sufferers with ASMD kind A/B or kind B have been randomized to obtain zempozyme or placebo for 52 weeks (major evaluation). In the examine, sufferers handled with Zenpozyme improved lung operate by 19% (p=0.0004) in comparison with the placebo arm, whereas spleen quantity decreased by 40% (p<0.0001) and spleen quantity decreased by 28% (p<). 0.0001) with the new treatment. Additionally, a 17% improve in platelet depend was noticed in sufferers handled with Genpozyme.®.

All ASCEND sufferers handled with Xenpozyme confirmed enchancment in major endpoints (lung operate, spleen and liver quantity), and the most incessantly reported opposed drug reactions (incidence ≥10%) in adults have been headache, cough, diarrhea, hypotension and ophthalmia.

The single-arm ASCEND-Peds examine studied 20 pediatric sufferers youthful than 18 years of age with ASMD kind A/B or kind B who acquired Xenpozyme.®With the major goal of evaluating the security and tolerability of Xenpozyme® for 64 weeks. All sufferers accomplished the examine and continued to take the drug in the prolonged examine. The ASCEND-Peds examine additionally explored efficacy endpoints in progressive lung illness, enlargement of the spleen and liver, and platelet counts. After one 12 months of treatment (52 weeks), there have been imply share enhancements in DLco, spleen and liver quantity, platelet depend, and linear development development (as measured by top Z scores) in comparison with baseline.

• At week 52 there was a 33% (p=0.0053) enchancment in lung operate (DLco) in comparison with baseline.

• There was a 49% imply discount in spleen quantity from baseline to week 52 (p<0.0001).

• There was a 40% (p < 0.0001) discount in imply liver quantity from baseline to week 52.

• 34% (p=0.0003) imply enchancment in platelet depend from baseline to week 52.

A scientific breakthrough for sufferers dwelling with ASMD

Xenpozyme®, an enzyme substitute remedy particular for hydrolytic lysosomal sphingomyelin, designed to interchange poor or faulty acid sphingomyelinase (ASM), the enzyme that permits degradation of the lipid sphingomyelin. In people with ASMD, deficiency of the ASM enzyme outcomes in accumulation of sphingomyelin in numerous tissues. Xenpozyme isn’t anticipated® Cross the blood-mind barrier or enhance the manifestation of ASMD in the CNS. Xenpozyme® Studies haven’t been performed in sufferers with ASMD kind A.

Xenpozyme® It is run intravenously each two weeks, and its administration requires a dose escalation part, adopted by a upkeep part.
