Prometic Presents New Data on PBI-4050 and its Mechanism of Action on Kidney Fibrosis at the 56th ERA/EDTA Congress

LAVAL, QC, ROCKVILLE, MD and CAMBRIDGE, United Kingdom, June 14, 2019 /PRNewswire/ - Prometic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) (Prometic), a biopharmaceutical company focused on developing novel therapeutics to treat unmet needs in patients with liver, respiratory and kidney disease, today announced that four abstracts highlighting Prometic's progress in developing PBI-4050 as a potential treatment for both acute kidney injury (AKI) and chronic kidney disease (CKD) will be presented at the 56^th Congress of the European Renal Association - European Dialysis and Transplant Association (ERA-EDTA). The Congress will take place on June 13 - 16, 2019 in Budapest, Hungary.

"These pre-clinical results provide additional evidence demonstrating the anti-fibrotic activity of PBI-4050 and therefore its potential as a novel therapy for the treatment of AKI and CKD," stated Kenneth Galbraith, Chief Executive Officer of Prometic. "We are encouraged by these results, which provide additional support for our decision to expand our development plans for PBI-4050 in fibrosis-related renal indications in 2020."

An oral presentation will discuss the mechanism of action of PBI-4050 onto GPR40 and GPR84, two promising biological targets in the treatment of kidney fibrosis. Results from cellular and animal models of acute and chronic kidney injuries, including data demonstrating that PBI-4050 reduced biomarkers associated with kidney injury from a previously-completed Phase 2 clinical study in patients with Type 2 diabetes and metabolic syndrome, will be presented by Dr. Lyne Gagnon, Prometic's Vice-President R&D, Preclinical, on June 14, 2019 at 8:00 a.m. CEST.

Three poster presentations will highlight the role of the two G protein-coupled receptors, GPR40 and GPR84, in various models of kidney injury and associated complications. The following posters will be presented:

- PBI-4050 Reduces Systemic Inflammation, Electrolyte Disturbances and Renal Injury in Mice with Sepsis-induced Acute Kidney Injury; Role of GPR84 (#FP266, June 14, 2019, 9:30 to 10:45 and 16:30 to 17:00).

- Activation of the Free-fatty Acid Receptor GPR40 Improves Anemia in Mouse Models of Kidney Disease Via a Novel EPO-Independent Mechanism of Action (#SP345, June 15, 2019, 9:30 to 10:45 and 16:30 to 17:00).

- PBI-4050 Improves Metabolic Regulation and Diabetic Nephropathy through Reduction of ER Stress, Pro-Inflammatory/Fibrotic Markers, Galectin-3 Expression and Inflammatory Cell Infiltration in ob/ob Mouse Model (#SP436, June 15, 2019, 9:30 to 10:45 and 16:30 to 17:00).

More About PBI-4050

PBI-4050 is an orally active lead drug candidate with excellent safety and efficacy profiles confirmed in several in vivo experiments targeting fibrosis. Fibrosis is a very complex process by which continuing inflammation causes vital organs to lose their function as normal tissue is replaced by fibrotic scar tissue. The proof of concept data generated to date confirms our lead drug candidates' anti-fibrotic activity in several key organs including the kidneys, lungs, liver and the heart.

About Prometic Life Sciences

Prometic (www.prometic.com) is an innovative biopharmaceutical corporation with a broad pipeline of small molecule therapeutics under development to treat unmet needs in patients with liver, respiratory and kidney disease, including rare diseases. Prometic's differentiated research involves the study of a new antifibrotic pathway involving two G-protein-coupled-receptors, GPR40 and GPR84. These drug candidates have a dual mode-of-action as agonists ("stimulators") of GPR40 and antagonists ("inhibitors") of GPR84. Our lead drug candidate, PBI-4050, is expected to enter Phase 3 clinical studies for the treatment of Alström Syndrome in 2019. A second drug candidate, PBI-4547, is expected to enter Phase 1 clinical studies in 2019. Prometic also has leveraged its experience in bioseparation technologies to isolate and purify biopharmaceuticals from human plasma. The lead plasma-derived therapeutic product is Ryplazim™ (plasminogen) for which the Company expects to file a BLA with the US FDA in 2019 seeking approval to treat patients with congenital plasminogen deficiency. The Corporation also operates a contract development and manufacturing operation in the United Kingdom, deriving revenue through sales of affinity chromatography media. Prometic has active business operations in Canada, the United States, the Isle of Man and the United Kingdom. For more information, please visit www.prometic.com.
