Translate Bio Presents MRT5005 Data at the 33rd Annual North American Cystic Fibrosis Conference
The poster presentation today and the oral presentation tomorrow describe the previously announced interim results from the single-ascending dose (SAD) portion of a first-in-human Phase 1/2 clinical trial of MRT5005 in 12 patients with CF. The multiple-ascending dose (MAD) portion of the clinical trial is ongoing with data expected in 2020.
“It’s an exciting time in the field of CF treatment where significant advancements have been made for the majority of people with CF; however, there are still those with different mutations who do not benefit from these new medicines,” said
The interim results describe data from 12 adult patients with CF who received a single dose of either MRT5005 or placebo (3:1 randomization). Patients who received MRT5005 were assigned to one of three dose groups (8, 16 or 24 mg). An overview of the results from the SAD portion of the study include:
- Marked increases in ppFEV1 after a single MRT5005 dose were observed in 4 of 9 patients, primarily at the mid-dose level
- ppFEV1 increases were observed in a patient considered non-amenable to current CFTR modulator regimens as well as in patients on CFTR modulator regimens
- Early improvement in ppFEV1 after a single dose suggests MRT5005 is crossing the mucus layer and enabling production of functional CFTR protein
- No serious adverse events were reported at any dose level
- MRT5005 was generally well tolerated at low and mid-dose levels; primarily at high dose, patients receiving a single dose of MRT5005 experienced transient, mild to moderate febrile reactions
- Evaluation of immunogenicity markers showed no detection of anti-CFTR anti-drug antibodies or T-cell sensitization
A copy of the poster and oral presentation will be available on Translate Bio’s investor website at the time of the data presentation.
About the Phase 1/2 Clinical Trial
The randomized, double-blind, placebo-controlled Phase 1/2 clinical trial of MRT5005 is designed to enroll up to 40 adult patients with CF who have two Class I and/or Class II mutations. The primary endpoint of the trial is to assess the safety and tolerability of single and multiple escalating doses of MRT5005 administered by nebulization. Percent predicted forced expiratory volume in one second (ppFEV1), which is a well-defined and accepted endpoint measuring lung function, is also being measured at pre-defined timepoints throughout the trial. The Phase 1/2 clinical trial of MRT5005 for the treatment of CF is being conducted in collaboration with the Cystic Fibrosis Foundation Therapeutics Development Network.
Translate Bio is a clinical-stage mRNA therapeutics company developing a new class of potentially transformative medicines to treat diseases caused by protein or gene dysfunction. The Company’s MRT platform is designed to develop product candidates that deliver mRNA carrying instructions to produce intracellular, transmembrane and secreted proteins for therapeutic benefit. Translate Bio is primarily focused on applying its MRT platform to pulmonary diseases caused by insufficient protein production or where production of proteins can modify disease. The Company also believes its technology is applicable to a broad range of diseases, including diseases that affect the liver, eye and central nervous system. Additionally, the MRT platform may be applied to various classes of treatments, such as therapeutic antibodies or vaccines in areas such as infectious disease and oncology. Translate Bio’s lead program is being developed as a treatment for cystic fibrosis (CF) and is in an ongoing Phase 1/2 clinical trial.
