Accord BioPharma Announces Commercial Launch of IMULDOSA® (ustekinumab-srlf) Prefilled Syringes at Lowest WAC Price Among Branded Biosimilars to STELARA® (ustekinumab)

Company's third biosimilar expands access to proven targeted biologic therapy with patient-centric support services and resources

RALEIGH, N.C., Aug. 18, 2025 /PRNewswire/ -- Accord BioPharma, Inc., the specialty division of Intas Pharmaceuticals, Ltd., focused on the development of oncology, immunology, and critical care therapies, announced today the commercial launch of IMULDOSA® (ustekinumab-srlf), a biosimilar to STELARA® (ustekinumab). IMULDOSA prefilled syringes, which would represent the majority of the presentations in the ustekinumab market, are priced at the lowest wholesaler acquisition cost (WAC) among all branded ustekinumab biosimilars at a 92% discount from STELARA. FDA-approved for the same indications as the reference product, IMULDOSA represents Accord BioPharma's third in-market biosimilar and furthers the company's mission to expand patient access to potentially life-changing biologic therapies.¹ Accord BioPharma is committed to providing patients with greater access to ustekinumab through this significant cost reduction.

This IMULDOSA launch will lay the foundation for Accord BioPharma's immunology franchise, demonstrating the company's commitment to addressing critical needs in immune-mediated inflammatory conditions.

Addressing Critical Patient Needs in the U.S.
Millions of Americans suffer from chronic, immune-mediated inflammatory conditions, such as plaque psoriasis, psoriatic arthritis, Crohn's disease, and ulcerative colitis.² These conditions are often not only incredibly painful and debilitating, but can also impact a person's quality of life, emotional well-being, and self-image.³⁻⁵ While biologics such as STELARA have had a transformative impact on the lives of many people in the U.S., they often come with a high cost that can prohibit access. Accord BioPharma's ustekinumab biosimilar IMULDOSA has been proven to be highly similar to STELARA with no clinically meaningful differences.¹ Please see below for full Indications and Important Safety Information.

As Accord BioPharma prepared for the commercial launch of IMULDOSA, the company solicited feedback from their patient advisory board on the development of patient support materials. The company is grateful for their invaluable input in these co-creation sessions.

Expanding Access for Eligible Patients
Accord BioPharma has priced IMULDOSA to maximize patient access across all formulations. The prefilled syringes feature the lowest WAC price among branded ustekinumab biosimilars at a 92% discount from STELARA, while the vial formulation offers a 30% discount.

Accord BioPharma is launching IMULDOSA with a $0 co-pay program for eligible patients so that more people living with plaque psoriasis, psoriatic arthritis, and Crohn's disease and ulcerative colitis can receive a proven targeted biologic therapy.

"At Accord BioPharma, we believe that cost shouldn't be a barrier to accessing proven, life-changing therapies," said Chrys Kokino, Accord U.S. President. "The launch of IMULDOSA represents our commitment to going beyond simply providing biosimilar alternatives to delivering comprehensive solutions that can make a meaningful difference in patients' lives. With our third biosimilar now available, we're demonstrating that Accord BioPharma is at the forefront of biosimilar transformation, backed by the 50-year heritage of our parent company, Intas Pharmaceuticals."

Backed by Proven Heritage and Commitment
Accord BioPharma believes deeply in the power of biosimilars to reshape the future of treatment. With the support of Intas, an established global leader with nearly five decades of experience, Accord BioPharma is transforming the conventional treatment landscape across several priority therapeutic areas by introducing biosimilars to the U.S. market.

"The launch of IMULDOSA in the United States represents our unwavering commitment to making high-quality, more cost-effective biologic therapies more accessible within immunology's critical therapeutic areas," said Binish Chudgar, Chairman and Managing Director of Intas Pharmaceuticals. "Through Accord BioPharma, we are establishing ourselves in the U.S. as a trusted, reliable ally highly attuned to the needs of our stakeholders and dedicated to transforming patient care."

Current Portfolio of Brands
Accord BioPharma's portfolio has experienced sizable growth within the past year. In addition to launching IMULDOSA, Accord BioPharma recently assumed U.S. operations for the full UDENYCA® (pegfilgrastim-cbqv) franchise, including the UDENYCA pre-filled syringe, the UDENYCA autoinjector, and UDENYCA ONBODY®. The company is also marketing HERCESSI™ (trastuzumab-strf), a biosimilar to Herceptin® (trastuzumab), and CAMCEVI® (leuprolide) 42 mg injectable emulsion. Please refer to the Important Safety Information and full Prescribing Information for all products.

Intas Pharmaceuticals, Ltd. has an exclusive agreement with Bio-Thera Solutions to enable Accord BioPharma to bring Bio-Thera's golimumab candidate BAT2506 – a biosimilar to Simponi® (golimumab) – to the U.S. market, further expanding Accord BioPharma's pipeline. Accord BioPharma has also submitted Biologics License Applications to the FDA for biosimilar versions of several other biologics.

IMPORTANT SAFETY INFORMATION
IMULDOSA is contraindicated in patients with clinically significant hypersensitivity to ustekinumab products or to any of the excipients in IMULDOSA.

Infections

• Ustekinumab products may increase the risk of infections and reactivation of latent infections. Serious bacterial, mycobacterial, fungal, and viral infections were observed in patients receiving ustekinumab products.
• Serious infections requiring hospitalization, or otherwise clinically significant infections, reported in clinical trials included the following:
  • Plaque psoriasis: diverticulitis, cellulitis, pneumonia, appendicitis, cholecystitis, sepsis, osteomyelitis, viral infections, gastroenteritis and urinary tract infections.
  • Psoriatic arthritis: cholecystitis.
  • Crohn's disease: anal abscess, gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeria meningitis.
  • Ulcerative colitis: gastroenteritis, ophthalmic herpes zoster, pneumonia, and listeriosis.
• Avoid initiating treatment with IMULDOSA in patients with any clinically important active infection until the infection resolves or is adequately treated. Consider the risks and benefits of treatment prior to initiating use of IMULDOSA in patients with a chronic infection or a history of recurrent infection.
• Instruct patients to seek medical advice if signs or symptoms suggestive of an infection occur while on treatment with IMULDOSA and discontinue IMULDOSA for serious or clinically significant infections until the infection resolves or is adequately treated.

Theoretical Risk for Vulnerability to Particular Infections

• Individuals genetically deficient in IL-12/IL-23 are particularly vulnerable to disseminated infections from mycobacteria (including nontuberculous, environmental mycobacteria), salmonella (including nontyphi strains), and Bacillus Calmette-Guerin (BCG) vaccinations. Serious infections and fatal outcomes have been reported in such patients.
• It is not known whether patients with pharmacologic blockade of IL-12/IL-23 from treatment with ustekinumab products may be susceptible to these types of infections. Consider appropriate diagnostic testing (e.g., tissue culture, stool culture, as dictated by clinical circumstances).

Pre-treatment Evaluation for Tuberculosis

• Evaluate patients for tuberculosis infection prior to initiating treatment with IMULDOSA. Avoid administering IMULDOSA to patients with active tuberculosis infection. Initiate treatment of latent tuberculosis prior to administering IMULDOSA. Consider anti-tuberculosis therapy prior to initiation of IMULDOSA in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed. Closely monitor patients receiving IMULDOSA for signs and symptoms of active tuberculosis during and after treatment.

Malignancies

• Ustekinumab products are immunosuppressants and may increase the risk of malignancy. Malignancies were reported among subjects who received ustekinumab in clinical trials. In rodent models, inhibition of IL-12/IL-23p40 increased the risk of malignancy.
• The safety of ustekinumab products has not been evaluated in patients who have a history of malignancy or who have a known malignancy.
• There have been post-marketing reports of the rapid appearance of multiple cutaneous squamous cell carcinomas in patients receiving ustekinumab products who had pre-existing risk factors for developing non-melanoma skin cancer. Monitor all patients receiving IMULDOSA for the appearance of non-melanoma skin cancer. Closely follow patients greater than 60 years of age, those with a medical history of prolonged immunosuppressant therapy and those with a history of PUVA treatment.

Hypersensitivity Reactions

• Hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with ustekinumab products. If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue IMULDOSA.

Posterior Reversible Encephalopathy Syndrome (PRES)

• Two cases of posterior reversible encephalopathy syndrome (PRES), also known as Reversible Posterior Leukoencephalopathy Syndrome (RPLS), were reported in clinical trials. Cases have also been reported in postmarketing experience in patients with psoriasis, psoriatic arthritis and Crohn's disease. Clinical presentation included headaches, seizures, confusion, visual disturbances, and imaging changes consistent with PRES a few days to several months after ustekinumab product initiation. A few cases reported latency of a year or longer. Patients recovered with supportive care following withdrawal of ustekinumab products.
• Monitor all patients treated with IMULDOSA for signs and symptoms of PRES. If PRES is suspected, promptly administer appropriate treatment and discontinue IMULDOSA.

Immunizations

• Prior to initiating therapy with IMULDOSA, patients should receive all age-appropriate immunizations as recommended by current immunization guidelines. Patients being treated with IMULDOSA should not receive live vaccines. Avoid administering BCG vaccines during treatment with IMULDOSA or for one year prior to initiating treatment or one year following discontinuation of treatment. Caution is advised when administering live vaccines to household contacts of patients receiving IMULDOSA because of the potential risk for shedding from the household contact and transmission to patient.
• Non-live vaccinations received during a course of IMULDOSA may not elicit an immune response sufficient to prevent disease.

Noninfectious Pneumonia

• Cases of interstitial pneumonia, eosinophilic pneumonia and cryptogenic organizing pneumonia have been reported during post-approval use of ustekinumab products. Clinical presentations included cough, dyspnea, and interstitial infiltrates following one to three doses. Serious outcomes have included respiratory failure and prolonged hospitalization. Patients improved with discontinuation of therapy and in certain cases administration of corticosteroids. If diagnosis is confirmed, discontinue IMULDOSA and institute appropriate treatment.

Most Common Adverse Reactions
The most common adverse reactions associated with ustekinumab products are:

• Psoriasis (≥3%): nasopharyngitis, upper respiratory tract infection, headache, and fatigue
• Crohn's Disease, induction (≥3%): vomiting
• Crohn's Disease, maintenance (≥3%): nasopharyngitis, injection site erythema, vulvovaginal candidiasis/mycotic infection, bronchitis, pruritus, urinary tract infection, and sinusitis
