Press Release

SOUTH SAN FRANCISCO, Calif., Aug. 11, 2020 /PRNewswire/ -- Pliant Therapeutics, Inc. (Nasdaq: PLRX), a clinical stage biotechnology company focused on discovering and developing novel therapeutics for the treatment of fibrosis, today provided a corporate update and reported second-quarter 2020 financial results.

"2020 has been a productive year as we've made progress on multiple fronts, including the initiation of a 12-week Phase 2a clinical trial evaluating PLN-74809 in patients with idiopathic pulmonary fibrosis, as well as dosing initial cohorts in our first-in-human trial of our Novartis partnered program, PLN-1474, for the potential treatment of liver fibrosis," said Bernard Coulie, M.D., Ph.D., chief executive officer and president of Pliant Therapeutics. "Bolstered by a strong cash position from our Series C financing in February and our IPO in June, we continue to advance our robust pipeline. We're now focused on executing our Phase 2a program for PLN-74809 and look forward to sharing further updates on all of our programs."

Recent Highlights

• Completed an initial public offering (IPO) and concurrent private placement with Novartis. The IPO priced at $16.00 per share, generating gross proceeds of $165.6 million including shares sold to the underwriters pursuant to the full exercise of their overallotment option before deducting underwriting discounts, commissions and other offering expenses payable by Pliant. The company also received $10.0 million in additional proceeds from a concurrent private placement with Novartis Institutes for BioMedical Research, Inc. at the public offering price of $16.00 per share. The Company's common stock commenced trading on the Nasdaq Global Select Market under the ticker symbol "PLRX" on June 3rd, 2020.


• Phase 2a 12-week trials of PLN-74809 in idiopathic pulmonary fibrosis (IPF) and primary sclerosing cholangitis (PSC) have resumed enrollment. Through close coordination with over 100 global trial sites, Pliant has continued to conduct site initiation activities throughout the COVID-19 pandemic. The Company is offering a hybrid approach to clinical trial participation with home-health solutions designed to minimize the requirements for visits to healthcare facilities, as well as a campaign to raise awareness of the IPF and PSC programs across patient communities and patient advocacy groups. Phase 2a clinical trial sites are currently enrolling patients in both the IPF and PSC trials.


• Opened Investigational New Drug (IND) Application for PLN-74809 for treatment of acute respiratory distress syndrome (ARDS) associated with COVID-19. Pliant submitted the COVID-19 ARDS IND in June and the FDA has since issued a "safe to proceed" letter. The Company plans to initiate a Phase 2 trial evaluating safety, tolerability and pharmacokinetics (PK) of PLN-74809, as well as exploratory clinical outcome measures in patients hospitalized with severe and critical COVID-19 in the second half of 2020. This represents the fourth IND that Pliant has successfully opened since operations began in 2016.


• Completed dosing of initial cohorts of a Phase 1 trial of PLN-1474. The Phase 1 trial is designed to evaluate safety and tolerability, as well as PK of PLN-1474 in approximately 100 healthy volunteers across a dose range compared to placebo. The Phase 1 trial site has experienced delays due to COVID-19; however, it is now open and expected to continue dosing the remaining cohorts with topline data expected in the first quarter of 2021, subject to further impact of the COVID-19 pandemic. PLN-1474 is partnered with Novartis.

COVID-19 Preparedness

Pliant has worked proactively to establish policies and procedures to enable the Company to operate safely and productively during the pandemic. The Company has experienced delays in clinical trial operations which will impact the expected timing of data readouts, but is working closely with clinical sites to continue site initiation activities in compliance with study protocols while observing government and institutional guidelines. The clinical site conducting Pliant's Phase 2a PET trial of PLN-74809 in IPF remains closed to clinical research, but expects to resume trial activities in the third quarter. Pliant has made significant progress in opening trial sites for its Phase 2a 12-week IPF and PSC trials by offering a hybrid approach to clinical trial participation with home-health solutions designed to minimize the requirements for visits to healthcare facilities, as well as a campaign to raise awareness of the IPF and PSC programs across patient communities and patient advocacy groups. The Company intends to provide more specific guidance regarding clinical trial progress and the timing of data readouts as the impacts of the pandemic are better understood.

• Related party revenue was $3.6 million as compared to nil for the prior-year period.
