Petrovax introduced at the moment the optimistic outcomes from “Lengthy-CoV-III-21,” a randomized, double-blind, placebo-controlled trial evaluating the efficacy and security of bovhyaluronidase azoximer in grownup sufferers with pulmonary sequelae of COVID-19. Bovhyaluronidase azoximer, marketed beneath the model identify Longidaza, is a polymer-conjugated hyaluronidase with an prolonged half-life. The examine drug and placebo have been administered for 71 days, with an commentary interval extending to Day 180.
Longidaza demonstrated a statistically important 62% discount within the proportion of sufferers with exertional desaturation (OR = 0.35, p = 0.0051) and a 27% discount within the proportion of sufferers exhibiting exertional dyspnea (OR = 0.62, p = 0.043) by Day 71 in comparison with placebo. Marked enhancements have been additionally noticed in resting dyspnea and distance walked through the six-minute stroll take a look at. The drug’s results on train tolerance indicators have been sustained for greater than 100 days after the final dose.
Longidaza didn’t have an effect on pulmonary operate within the total inhabitants. Nevertheless, subgroup evaluation revealed that the drug was related to a considerably larger change from baseline in predicted Pressured Important Capability (FVC) in sufferers with cardiovascular comorbidities (distinction = 3.31%, p = 0.042) and in these contaminated with earlier variants of SARS-CoV-2 (distinction = 4.17%, p = 0.021) in comparison with placebo.
Lengthy-CoV-III-21 is among the many first randomized, double-blind trials to indicate a big impact of a novel remedy in sufferers with post-COVID pulmonary sequelae. The sustained results of Longidaza supply hope for sufferers scuffling with dyspnea, fatigue, and decreased bodily capability to enhance their high quality of life. Though the drug didn’t present a big impact on pulmonary operate restoration in the whole examine inhabitants, ends in subgroups strongly counsel that analysis into hyaluronidase-based medicines ought to continue-;not just for post-COVID pulmonary sequelae but in addition for different fibrotic situations.”

Research findings have been introduced on the Asian Pacific Society of Respirology congress in Hong Kong.
In parallel with lengthy COVID analysis, Petrovax has been growing an inhaled type of Longidaza for the remedy of interstitial lung illnesses. The protection of this new supply route was demonstrated in a current Section 1 examine. A Section 2 trial of inhaled Longidaza in sufferers with idiopathic pulmonary fibrosis is deliberate for 2025.
About Lengthy-CoV-III-21
Lengthy-CoV-III-21 is a potential, randomized, double-blind, placebo-controlled scientific trial designed to check the efficacy and security of Longidaza (3000U) intramuscular injections in sufferers with pulmonary sequelae of COVID-19 (NCT06383819). 300 ninety-two sufferers have been randomized 1:1 to obtain both Longidaza or placebo each 5 days for 71 days. The follow-up interval lasted as much as Day 180. The examine enrolled sufferers with a historical past of COVID-19 an infection 1 to 12 months previous to screening, restrictive lung illness, fibrotic-like radiological abnormalities within the lungs, and decreased SpO2 at relaxation or after exertion. The examine was carried out at 37 scientific websites.
The first endpoint was the change from baseline in predicted Pressured Important Capability.
The primary secondary endpoints included the proportions of sufferers with exertional desaturation and dyspnea after the six-minute stroll take a look at, the space walked within the six-minute stroll take a look at, and dyspnea at relaxation.
