Lipocine Announces Positive Topline Phase 2 Results from LPCN 1144 Ongoing LiFT Study in Biopsy-Confirmed NASH Subjects

 

SALT LAKE CITY, Jan. 12, 2021 /PRNewswire/ -- Lipocine Inc. (NASDAQ: LPCN), a clinical-stage biopharmaceutical company focused on metabolic and endocrine disorders, today announced positive topline results from its LiFT ("Liver Fat intervention with oral Testosterone") Phase 2 clinical study (NCT04134091), investigating LPCN 1144 in biopsy-confirmed non-cirrhotic non-alcoholic steatohepatitis ("NASH") male subjects. Currently, there are no approved treatments for NASH, a silent killer that affects ~30 million Americans. LPCN 1144 is an oral prodrug of endogenous testosterone. 

In the ongoing randomized, double-blind, placebo-controlled 36-week treatment LiFT study, subjects with F1-F3 fibrosis were randomized 1:1:1 to one of three arms (Treatment A is a twice daily oral dose of 142 mg testosterone equivalent, Treatment B is a twice daily oral dose of 142 mg testosterone equivalent formulated with 217 mg of d-alpha tocopherol equivalent, and the third arm is twice daily matching placebo). The primary endpoint is change in hepatic fat fraction via Magnetic Resonance Imaging Proton Density Fat Fraction ("MRI-PDFF") and exploratory liver fat/marker end points post 12 weeks of treatment. Additionally, key secondary endpoints post 36 weeks of treatment include assessment of histological change for NASH resolution and/or fibrosis improvement as well as liver fat data.

Subjects will have access to LPCN 1144 through an open label extension study (NCT04685993). The extension study will enable the collection of additional data on LPCN 1144 for up to a total of 72 weeks of therapy

Treatments with LPCN 1144 post 12 weeks of treatment resulted in robust liver fat reduction, assessed by MRI-PDFF, and showed improvement of liver injury markers with no observed tolerability issues. Inclusion of d-alpha tocopherol formulated with the testosterone prodrug resulted in additional liver benefits, notably improved key liver markers without compromising tolerability.

Key results are presented in the following tables:

During the 12 weeks of treatment, the observed rate and severity of Treatment Emergent Adverse Events ("TEAEs") in both the treatment arms were comparable to the placebo arm. Three subjects in the placebo group and one subject in the combined treatment arms discontinued study drug due to TEAEs.

"The LiFT study provides the first proof of concept that LPCN 1144 improves both liver fat and markers of liver injury in patients with biopsy proven NASH with fibrosis, with the majority of patients experiencing greater than 30% reduction in liver fat.  The addition of d-alpha tocopherol appears to further reduce liver injury in this population.  These data appear to support the potential for this novel approach as a treatment of NASH," said Dr. Arun Sanyal, Professor in the Virginia Commonwealth University ("VCU") Department of Internal Medicine and Education Core Director in the VCU Center for Clinical and Translational Research

"We are pleased by the top-line results from our LiFT study, which we believe demonstrate the potential for oral LPCN 1144's to be used in treating NASH," said Dr. Mahesh Patel, Chairman, President and CEO of Lipocine Inc. "Additionally, NASH patients are likely to have compromised androgen signaling with associated sarcopenia, skeletal fragility, sexual/mood disorder, and anemia. Therefore, we believe LPCN 1144 therapy has the potential to provide additional benefits such as improved bone density and muscle mass as well as improvement in sexual/mental disorders. We look forward to sharing 36-week biopsy data from the LiFT study in mid-2021," said Dr. Patel.

About NASH

NASH is a more advanced state of non-alcoholic fatty liver disease ("NAFLD") and can progress to a cirrhotic liver and eventually hepatocellular carcinoma/liver cancer. Twenty to thirty percent of the U.S. population is estimated to suffer from NAFLD and fifteen to twenty percent of this group progress to NASH, which is a substantially large population that lacks effective therapy. Currently, there are no FDA approved treatments for NASH. Approximately 50% of NASH patients are in adult males and the number of NASH cases is projected to increase 63% from 16.5 million cases in 2015 to 27.0 million cases in 2030. NAFLD/NASH is becoming more common due to its strong correlation with obesity and metabolic syndrome, including components of metabolic syndrome such as diabetes, cardiovascular disease and high blood pressure. In men, especially with comorbidities associated with NAFLD/NASH, testosterone deficiency has been associated with an increased accumulation of visceral adipose tissue and insulin resistance, which could be factors contributing to NAFLD/NASH.

About Lipocine

Lipocine Inc. is a clinical-stage biopharmaceutical company focused on metabolic and endocrine disorders using its proprietary drug delivery technologies. Lipocine's clinical development pipeline includes: TLANDO, LPCN 1144, TLANDO XR, LPCN 1148 and LPCN 1107. TLANDO, a novel oral prodrug of testosterone containing testosterone undecanoate, has received tentative approval from the FDA for conditions associated with a deficiency of endogenous testosterone, also known as hypogonadism, in adult males. LPCN 1144, an oral prodrug of bioidentical testosterone, recently completed a proof-of-concept clinical study demonstrating the potential utility in the treatment of non-cirrhotic NASH. LPCN 1144 is currently being studied in a Phase 2 clinical study.  TLANDO XR, a novel oral prodrug of testosterone, originated and is being developed by Lipocine as a next-generation oral testosterone product with potential for once-daily dosing. In a phase 2 clinical evaluation when administered as once daily or twice daily TLANDO XR met the typical primary and secondary end points. LPCN 1148 is an oral prodrug of bioidentical testosterone targeted for the treatment of cirrhosis. LPCN 1107 is potentially the first oral hydroxyprogesterone caproate product candidate indicated for the prevention of recurrent preterm birth and has been granted orphan drug designation by the FDA.
