HLS Therapeutics Files New Drug Submission for PERSERIS® in Canada

If approved by Health Canada, PERSERIS would become the first once-monthly risperidone long-acting injectable used in the treatment of schizophrenia

TORONTO, Jan. 23, 2020 /CNW/ - HLS Therapeutics Inc. ("HLS" or the "Company") (TSX:HLS), a specialty pharmaceutical company focusing on central nervous system and cardiovascular markets, announces that its New Drug Submission ("NDS") for PERSERIS®, a novel long-acting injectable risperidone product for the treatment of schizophrenia was accepted for review by Health Canada on January 23, 2020. HLS is seeking approval for PERSERIS with an indication for the treatment of schizophrenia in adults.

HLS has in-licensed the exclusive rights to PERSERIS for the Canadian market from Indivior PLC. PERSERIS is not approved in Canada.

"Schizophrenia is a critical and fragile disease state where the treatment requirements are immense and complex. As a result, treatment adherence is a significant challenge," said Greg Gubitz, CEO of HLS Therapeutics. "We want to leverage our experience and our presence in this therapeutic area to provide practitioners with new and innovative treatments to help patients with schizophrenia. PERSERIS, if approved, with its unique sub-cutaneous long-acting injectable delivery formulation, could bring another treatment option to patients and practitioners.  Furthermore, it is complementary to our CNS business, which includes CLOZARIL® for treatment resistant schizophrenia, and CSAN® Pronto™ a point of care testing device for measuring white blood cells."

Risperidone is a well-established treatment for schizophrenia and PERSERIS uses a sub-cutaneous extended-release delivery system that forms a depot providing sustained therapeutic levels of risperidone over a one-month period from a single injection.


PERSERIS is approved by the FDA and is the first once-monthly subcutaneous risperidone-containing long-acting injectable indicated for the treatment of schizophrenia in adults. The PERSERIS approval by the FDA was based on a pivotal Phase 3 study in patients aged 18 to 55 years with acute exacerbations of schizophrenia (NCT 02109562). The primary efficacy endpoint measure was change in Positive and Negative Syndrome Scale (PANSS) total score at eight weeks. Both PERSERIS 90 mg and 120 mg doses demonstrated a statistically significant improvement compared with placebo from baseline to end of study.

The systemic safety profile of PERSERIS is consistent with the known safety profile of oral risperidone.1 The most common systemic adverse reactions in the pivotal Phase 3 trial (in ≥5 percent of PERSERIS patients and greater than twice placebo) were increased weight, sedation/somnolence and musculoskeletal pain. The most common injection site reactions (≥5 percent of all patients across PERSERIS and placebo groups) were injection site pain and reddening of the skin.1
