Exhibit 99.1
Ionis announces positive topline results from Essence study of olezarsen in people with moderately elevated triglycerides
– Olezarsen met the primary endpoint with a statistically significant mean reduction
in triglycerides versus placebo at 80 mg and 50 mg doses –
– Olezarsen met all key secondary endpoints –
– Olezarsen demonstrated a favorable safety and tolerability profile –
–Nearly 1,500-person study supports the exposure database for olezarsen –
– Data from pivotal Phase 3 CORE and CORE2 studies of olezarsen in severe
hypertriglyceridemia (sHTG) expected in Q3 2025 –
CARLSBAD, Calif., May 19, 2025 -- Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today announced
positive topline results from the Essence study of olezarsen in people with moderate hypertriglyceridemia (fasting triglycerides ≥150 mg/dL to <500 mg/dL) with or at risk for atherosclerotic cardiovascular disease (ASCVD). Nearly all the
participants were on current standard of care lipid-lowering medicines. The trial met its primary endpoint with a statistically significant placebo-adjusted 61% and 58% reduction in triglyceride (TG) levels at 6 months with the 80 mg and 50 mg
monthly doses, respectively (p <0.0001). Olezarsen also met all key secondary endpoints in the study. The vast majority of participants reached <150mg/dL, reflecting a reduction to normal TG levels. Olezarsen demonstrated a favorable safety
and tolerability profile in the study. Ionis plans to submit an abstract for presentation at an upcoming scientific conference. Data from the pivotal Phase 3 CORE and CORE2 studies evaluating olezarsen for the treatment of severe
hypertriglyceridemia (sHTG) are expected in Q3 2025.
“The positive results of this study are an important step in bringing forward a potential new treatment for people with severely elevated triglycerides. Following the FDA
approval and encouraging launch of TRYNGOLZA (olezarsen) for people living with familial chylomicronemia syndrome (FCS), a rare, genetic form of severely elevated TGs, these data support olezarsen’s potential to benefit the much broader population of
people living with sHTG,” said Sam Tsimikas, M.D., senior vice president, global cardiovascular development at Ionis. “We look forward to seeing the results of our pivotal Phase 3 studies, CORE and CORE2, in Q3 2025, which will be the basis for our
potential sNDA filing in sHTG by year-end.”
Olezarsen demonstrated a favorable safety and tolerability profile in the study. The most common treatment-emergent adverse event that occurred more frequently than placebo
in the olezarsen groups was injection site reactions, with the majority being mild in severity.
About the Essence Study
The Phase 3 global, multicenter, randomized, double-blind, placebo-controlled study (Essence-TIMI 73b), conducted with Ionis’ research partner, The TIMI Study Group,
supports the exposure database for olezarsen (NCT05610280). Essence enrolled 1,478 participants aged 18 and older with moderate hypertriglyceridemia (HTG), defined as
fasting triglyceride levels ≥150 mg/dL to <500 mg/dL, who were diagnosed with or at risk for atherosclerotic cardiovascular disease (ASCVD). A small percentage of participants (9%) had fasting triglycerides ≥500 mg/dL at baseline. Participants in
the study received stable and optimized standard of care lipid-lowering therapies for at least four weeks prior to screening. Participants were randomized to receive 50 mg (n=276) or 80 mg (n=832) of olezarsen or placebo (n=369) every 4 weeks via
subcutaneous injection for 12 months.
The primary endpoint was the percent change from baseline in fasting TG levels at six months compared to placebo. Key secondary endpoints included percent
changes in triglyceride levels at 12 months, proportion of patients who achieve fasting TG<150 mg/dL and percent changes in other lipid parameters, including apoC-III, remnant cholesterol, non-HDL-C and apoB, compared to placebo over the
treatment period.
About Hypertriglyceridemia
Triglycerides (TG) are a type of fat the body uses as a source of energy. While optimal levels for adults are typically below 150 mg/dL, levels higher than 150 mg/dL are a
sign of hypertriglyceridemia. Levels higher than 500 mg/dL are a sign of a common condition called severe hypertriglyceridemia (sHTG), which puts millions of people at risk of potentially life-threatening acute pancreatitis (AP) and atherosclerotic
cardiovascular disease (ASCVD) despite current standard of care. People with sHTG whose triglyceride levels are more than 880 mg/dL, including those with familial chylomicronemia syndrome (FCS), face a greater risk of AP.
About Olezarsen
Olezarsen is an investigational RNA-targeted medicine being evaluated for the treatment of sHTG. Olezarsen is designed to lower the body's production of apoC-III, a protein
produced in the liver that regulates triglyceride metabolism in the blood. The investigational medicine is currently being evaluated in two Phase 3 clinical trials – CORE
and CORE2 – for the treatment of sHTG. Olezarsen has not been approved for the
treatment of sHTG by regulatory authorities.
Olezarsen was recently approved in the U.S. as an adjunct to diet to reduce triglycerides in adults with FCS under the tradename TRYNGOLZA™ (olezarsen). For more
information about TRYNGOLZA, visit TRYNGOLZA.com.
U.S. INDICATION for TRYNGOLZA™ (olezarsen)
TRYNGOLZA is an adjunct to diet to reduce triglycerides in adults with familial chylomicronemia syndrome (FCS).
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
TRYNGOLZA is contraindicated in patients with a history of serious hypersensitivity to TRYNGOLZA or any of the excipients in TRYNGOLZA. Hypersensitivity reactions requiring
medical treatment have occurred.
WARNINGS AND PRECAUTIONS
Hypersensitivity Reactions
Hypersensitivity reactions (including symptoms of bronchospasm, diffuse erythema, facial swelling, urticaria, chills and myalgias) have been reported in patients treated
with TRYNGOLZA. Advise patients on the signs and symptoms of hypersensitivity reactions and instruct patients to promptly seek medical attention and discontinue use of TRYNGOLZA if hypersensitivity reactions occur.
ADVERSE REACTIONS
The most common adverse reactions (incidence >5% of TRYNGOLZA-treated patients and >3% higher frequency than placebo) were injection site reactions, decreased
platelet count and arthralgia.
Please see full Prescribing Information for TRYNGOLZA.
