First patients included in large placebo-controlled multicentre study on ColdZyme

Enzymatica has initiated a prospective double-blind, placebo-controlled multicentre study to evaluate the effects of ColdZyme® Mouth Spray on the common cold. The study will include 600 patients and is conducted at 10 study centres in Germany. The first patients have now been enrolled in the study, which is expected to be completed during the second half of 2019.

The goal of the study is to evaluate clinical effects of ColdZyme on the common cold. The primary objective is to assess the effect of ColdZyme on quality of life during a common cold period, with the Wisconsin Upper Respiratory Symptom Survey (WURSS-21) Quality of Life (QoL) subscore.

A total of 600 participants will be enrolled in the study at 10 study centres in Germany. The participants will be randomised to treatment with ColdZyme or placebo.

The study is a follow-up of a single-blind, prospective, controlled multicentre study of ColdZyme that Enzymatica conducted during the 2018 cold season. That study showed a significant reduction of both the duration of the cold and the intensity of symptoms with use of ColdZyme, as well as improved quality of life and reduced use of symptom-relieving drugs, compared to a control group that did not use ColdZyme. A total of 267 people with confirmed colds were evaluated in the study.

"In the new placebo-controlled study we want to confirm the very strong results of the previous multicentre study, establish ColdZyme as an evidence-based treatment for the common cold and thereby accelerate our international expansion, which is already underway," says Fredrik Lindberg, CEO of Enzymatica.
