Pliant Therapeutics Provides Corporate Update and
Reports Fourth Quarter and Full Year 2021 Financial Results
SOUTH SAN FRANCISCO, CA., February 28, 2022 - 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 fourth quarter and full year 2021 financial results.
“In 2021 strong execution drove significant advancement of our pipeline. The achievement of strategic milestones and positive data further de-risked our ongoing and potential future clinical programs,” said Bernard Coulie, M.D., Ph.D., President and Chief Executive Officer of Pliant Therapeutics. “We are building on this momentum in 2022 with significant data readouts anticipated in our lead programs of idiopathic pulmonary fibrosis and primary sclerosing cholangitis, as well as planned investigational new drug applications in our oncology and muscular dystrophy programs.”
Fourth Quarter and Recent Highlights
Results from expanded PLN-74809 Phase 1b proof-of-mechanism trial demonstrated clear evidence of on-target biological activity in the lungs of healthy participants. Earlier today, the Company announced that positive data from an expanded PLN-74809 Phase 1b proof-of-mechanism trial demonstrated clear evidence of on-target biological activity in the lungs of 36 healthy participants. Results demonstrated that PLN-74809 inhibited TGF-β activation by up to 92% and 76% at 6- and 24-hours, respectively, following seven days of once-daily dosing. At all dose levels, PLN-74809 demonstrated durable pSmad suppression relative to placebo at 6 hours and 24 hours. PLN-74809 was well tolerated with mostly mild adverse events, and no severe adverse events.
Enrollment was completed in the PLN-74809 Phase 2a INTEGRIS-IPF trial in idiopathic pulmonary fibrosis. INTEGRIS-IPF is a 12-week randomized, dose-ranging, double-blind, placebo-controlled trial evaluating the safety, tolerability and pharmacokinetics of PLN-74809 at doses of 40, 80 or 160 mg in approximately 84 IPF patients. Exploratory endpoints include quantitative lung fibrosis (QLF) imaging, pulmonary function tests as well as select biomarkers. Topline data is anticipated mid-2022.
The U.S. Food and Drug Administration (FDA) authorized the evaluation of long-term treatment with PLN-74809 in patients with IPF. The FDA has authorized evaluation of long-term dosing of PLN-74809 up to 320 mg daily in patients with IPF. This authorization will facilitate longer-term pivotal trials in IPF. PLN-74809 has been administered to over 450 study participants, including healthy volunteers and patients, with no drug-related serious adverse events or severe adverse advents reported to date.
Independent Data Safety Monitoring Board (DSMB) recommended INTEGRIS-IPF Phase 2a Trial continue without modifications. Following the full enrollment of the INTEGRIS-IPF Phase 2a trial, on February 17, 2022, the DSMB recommended the INTEGRIS-IPF trial continue without modification. This review included all patients enrolled in all dose cohorts of the trial. To date, no safety concerns have been identified by the DSMB.
Commenced enrollment of a Phase 2a trial of PLN-74809 at a dose of 320 mg in patients with IPF. The Company began enrollment in a randomized, double-blind, placebo-controlled trial evaluating PLN-74809 at doses of 320 mg administered daily over at least six months, and up to 48 weeks, in approximately 28 patients with IPF. The primary endpoint is the evaluation of PLN-74809 safety and tolerability and the secondary endpoint is the assessment of pharmacokinetics. Exploratory endpoints will measure QLF imaging and pulmonary function tests as well as select biomarkers over 6 months of treatment.
PLN-74809 Phase 2a trial in primary sclerosing cholangitis (PSC) enrollment on track to be completed mid-2022. INTEGRIS-PSC is a 12-week randomized, dose-ranging, double-blind, placebo-controlled trial evaluating the safety, tolerability, and pharmacokinetics of PLN-74809 at doses of 40, 80 or 160 mg in approximately 84 PSC



patients. Exploratory endpoints include fibrosis biomarkers such as Pro-C3 and ELF, changes in ALP and liver imaging. Topline data is expected in late 2022 or early 2023.
Oncology and muscular dystrophy programs progressing through Investigational New Drug (IND) enabling studies. Both programs on track with IND application submissions planned by the end of 2022.
COVID-19 Preparedness
The Company continues to develop and maintain policies and procedures to enable us to operate safely and productively during the COVID-19 pandemic. The Company has experienced delays in clinical trial operations which have impacted and may further impact the expected timing of data readouts. The Company is working closely with clinical sites to continue site initiation and operation activities in compliance with study protocols while observing government and institutional guidelines. The Company intends to provide more specific guidance regarding clinical trial progress and the timing of data readouts as the long-term impacts of the pandemic become better understood.
Fourth Quarter 2021 Financial Results
Research and development expenses were $18.8 million, as compared to $17.9 million for the prior-year quarter. The increase was due primarily to employee related expenses and higher costs related to the advancement of several programs and ongoing Phase 1/2 clinical trials.
General and administrative expenses were $7.8 million, as compared to $5.6 million for the prior-year quarter. The increase was due to higher personnel-related and professional services expenses.
Net loss of $24.5 million, as compared to $19.0 million for the prior-year quarter. The increase is due an overall increase in operating expense coupled with a decrease in revenues generated from our license and collaboration agreement.
As of December 31, 2021, the Company had cash, cash equivalents and short-term investments of $200.6 million. The Company believes it has sufficient funds to meet its operating and capital requirements into the second half of 2023.
