Ironwood Pharmaceuticals Provides Update on FY 2022 Financial Guidance and Announces FY 2023 Financial Guidance

BOSTON--(BUSINESS WIRE)-- Ironwood Pharmaceuticals, Inc. (Nasdaq: IRWD), a GI-focused healthcare company, today provided updated financial guidance for full year 2022 and announced financial guidance for full year 2023. The results were announced in advance of the Company’s presentation at the 41st Annual J.P. Morgan Healthcare Conference, which will take place on Wednesday, January 11, 2023 at 9:00 a.m. PT / 12:00 p.m. ET.

“Execution across our strategic priorities last year is positioning Ironwood for growth in 2023 and beyond,” said Tom McCourt, chief executive officer of Ironwood. “In 2022, we are on track to deliver another year of strong profits and expect to end the year with approximately $650 million of cash and cash equivalents on the balance sheet. Our performance continues to be driven by strong LINZESS prescription demand growth and disciplined expense management. We’re excited about the potential to expand the clinical utility of LINZESS based on the recent sNDA submission in functional constipation for pediatric patients aged 6 to 17 years old, which, if approved, would make LINZESS the first and only FDA approved prescription therapy for this patient population.”

“Looking ahead in 2023, we remain committed to further advancing our strategic priorities, unlocking new opportunities for LINZESS, and strengthening and progressing our innovative GI portfolio. We expect to deliver high single-digit LINZESS demand growth and maintain class-leading formulary access, which we believe will result in LINZESS net sales growth of between 3% to 5% in 2023. In addition, in 2023, we anticipate reaching new clinical development milestones, including data in the second half of the year for CNP-104, and we expect to deliver greater than $250 million in adjusted EBITDA. Overall, we believe we are positioning the company well for long term growth and remain focused on delivering patient benefit and shareholder value.”

About LINZESS (linaclotide)
LINZESS® is the #1 prescribed brand in the U.S. for the treatment of adult patients with irritable bowel syndrome with constipation (“IBS-C”) or chronic idiopathic constipation (“CIC”), based on IQVIA data.

LINZESS is a once-daily capsule that helps relieve the abdominal pain, constipation, and overall abdominal symptoms of bloating, discomfort and pain associated with IBS-C, as well as the constipation, infrequent stools, hard stools, straining, and incomplete evacuation associated with CIC. The recommended dose is 290 mcg for IBS-C patients and 145 mcg for CIC patients, with a 72-mcg dose approved for use in CIC depending on individual patient presentation or tolerability. LINZESS should be taken at least 30 minutes before the first meal of the day.

LINZESS is contraindicated in pediatric patients less than 2 years of age. In neonatal mice, linaclotide increased fluid secretion as a consequence of age-dependent elevated GC-C agonism resulting in mortality within the first 24 hours due to dehydration. There was no age-dependent trend in GC-C intestinal expression in a clinical study of children 2 to less than 18 years of age; however, there are insufficient data available on GC-C intestinal expression in children less than 2 years of age to assess the risk of developing diarrhea and its potentially serious consequences in these patients. The safety and effectiveness of LINZESS in patients less than 18 years of age have not been established.

LINZESS is not a laxative; it is the first medicine approved by the FDA in a class called GC-C agonists. LINZESS contains a peptide called linaclotide that activates the GC-C receptor in the intestine. Activation of GC-C is thought to result in increased intestinal fluid secretion and accelerated transit and a decrease in the activity of pain-sensing nerves in the intestine. The clinical relevance of the effect on pain fibers, which is based on nonclinical studies, has not been established.

In the United States, Ironwood and AbbVie co-develop and co-commercialize LINZESS for the treatment of adults with IBS-C or CIC. In Europe, AbbVie markets linaclotide under the brand name CONSTELLA® for the treatment of adults with moderate to severe IBS-C. In Japan, Ironwood’s partner, Astellas, markets linaclotide under the brand name LINZESS for the treatment of adults with IBS-C or CIC. Ironwood also has partnered with AstraZeneca for development and commercialization of LINZESS in China, and with AbbVie for development and commercialization of linaclotide in all other territories worldwide.

LINZESS Important Safety Information

INDICATIONS AND USAGE
LINZESS (linaclotide) is indicated in adults for the treatment of both irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC).

IMPORTANT SAFETY INFORMATION

Contraindications

• LINZESS is contraindicated in patients less than 2 years of age due to the risk of serious dehydration.
• LINZESS is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction.

Warnings and Precautions
Pediatric Risk

• LINZESS is contraindicated in patients less than 2 years of age. In neonatal mice, linaclotide increased fluid secretion as a consequence of age-dependent elevated GC-C agonism resulting in mortality within the first 24 hours due to dehydration. There was no age-dependent trend in GC-C intestinal expression in a clinical study of children 2 to less than 18 years of age; however, there are insufficient data available on GC-C intestinal expression in children less than 2 years of age to assess the risk of developing diarrhea and its potentially serious consequences in these patients. The safety and effectiveness of LINZESS in patients less than 18 years of age have not been established.

Diarrhea

• Diarrhea was the most common adverse reaction in LINZESS-treated patients in the pooled IBS-C and CIC double-blind placebo-controlled trials. The incidence of diarrhea was similar in the IBS-C and CIC populations. Severe diarrhea was reported in 2% of 145 mcg and 290 mcg LINZESS-treated patients, and in <1% of 72 mcg LINZESS-treated CIC patients. If severe diarrhea occurs, dosing should be suspended and the patient rehydrated.

Common Adverse Reactions (incidence ≥2% and greater than placebo)

• In IBS-C clinical trials: diarrhea (20% vs 3% placebo), abdominal pain (7% vs 5%), flatulence (4% vs 2%), headache (4% vs 3%), viral gastroenteritis (3% vs 1%) and abdominal distension (2% vs 1%).
• In CIC trials of a 145 mcg dose: diarrhea (16% vs 5% placebo), abdominal pain (7% vs 6%), flatulence (6% vs 5%), upper respiratory tract infection (5% vs 4%), sinusitis (3% vs 2%) and abdominal distension (3% vs 2%). In a CIC trial of a 72 mcg dose: diarrhea (19% vs 7% placebo) and abdominal distension (2% vs <1%).

____________________
¹ Guidance based on unaudited, preliminary and estimated amounts and may change as we receive final 2022 data and complete the preparation of our 2022 financial statements.
² 2022 LINZESS U.S. net sales is unaudited, preliminary and based on estimates, and may change as we receive final 2022 data from AbbVie Inc. and as we and AbbVie complete the preparation of our respective 2022 financial statements. LINZESS U.S. net sales are reported by AbbVie and LINZESS costs incurred by each of us and AbbVie are reported in our respective financial statements.
³ Adjusted EBITDA is calculated by subtracting mark-to-market adjustments on derivatives related to our 2022 Convertible Notes, restructuring expenses, net interest expense, income taxes, depreciation and amortization, from GAAP net income. For purposes of this guidance, we have assumed that Ironwood will not incur material expenses related to business development activities in 2022 and 2023. Ironwood does not provide guidance on GAAP net income or a reconciliation of expected adjusted EBITDA to expected GAAP net income because, without unreasonable efforts, it is unable to predict with reasonable certainty the non-GAAP adjustments used to calculate adjusted EBITDA. These adjustments are uncertain, depend on various factors and could have a material impact on GAAP net income for the guidance period. Management believes this non-GAAP information is useful for investors, taken in conjunction with Ironwood’s GAAP financial statements, because it provides greater transparency and period-over-period comparability with respect to Ironwood’s operating performance. These measures are also used by management to assess the performance of the business. Investors should consider these non-GAAP measures only as a supplement to, not as a substitute for or as superior to, measures of financial performance prepared in accordance with GAAP. In addition, these non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies.
