FDA approves Selarsdi injection as interchangeable with Stelara

Yahoo06-05-2025
Teva Pharmaceuticals and Alvotech have announced that the US Food and Drug Administration (FDA) has approved the Selarsdi (ustekinumab-aekn) injection as interchangeable with reference biologic Stelara (ustekinumab).
As of 30 April, Selarsdi is now available and interchangeable in all presentations that correspond with Stelara, including the treatment for both adult and pediatric patients with psoriatic arthritis, plaque psoriasis, ulcerative colitis, and Crohn's disease.
Selarsdi's approved presentations include a subcutaneous injection with 45mg/0.5ml and 90mg/ml in a single-dose prefilled syringe, as well as 45mg/0.5ml in a single-dose vial.
The approved presentation is also for intravenous infusion with 130mg/26ml in a single-dose vial.
Teva Pharmaceuticals US biosimilars senior vice-president Thomas Rainey said: "The FDA's confirmation of full interchangeability for Selarsdi is an important development for patients and providers seeking to expand access to this important treatment.
"Teva's recent launch of two biosimilars – Selarsdi and Epysqli – coupled with a rich pipeline of assets expected to launch over the next few years, position Teva to establish a strong leadership position in the growing landscape of biosimilars and to drive growth for the company as it embarks on the next phase of its strategy."
Ustekinumab, the active component in Selarsdi, is a human monoclonal antibody (mAb) that targets the p40 protein.
This protein is a shared component of interleukin (IL)-12 and IL-23 cytokines, which are critical in treating immune-mediated conditions such as psoriasis and psoriatic arthritis, as well as inflammatory conditions such as ulcerative colitis and Crohn's disease.
Alvotech developed and produces Selarsdi, leveraging Sp2/0 cells and a continuous perfusion method. The injection has been approved as Selarsdi in the US and introduced under various names in different regions, including Jamteki in Canada, Uzpruvo in Europe, and Ustekinumab BS (F) in Japan.
Applications are being reviewed in several nations worldwide.
The strategic partnership between the companies, initiated in August 2020, was established for the exclusive commercialisation of five biosimilar product candidates of Alvotech.
In July 2023, the collaboration expanded to include two additional biosimilars and new presentations of two previously collaborated products.
Including Selarsdi, the companies have seen two biosimilars developed by them gain US regulatory approval with interchangeability.
Alvotech and Teva noted that they have three additional biosimilar candidates under review by the US regulator: a proposed biosimilar for Simponi (golimumab) and Simponi Aria (golimumab), AVT05, and AVT06, which is a proposed biosimilar for Eylea (aflibercept).

TMO Receives FDA Approval for Oncomine Dx Target Test

Thermo Fisher Scientific TMO recently received approval from the Food and Drug Administration ('FDA') for its Oncomine Dx Target Test as a companion diagnostic (CDx) to identify patients who may be candidates for HERNEXEOS (zongertinib tablets), a tyrosine kinase inhibitor (TKI). The HERNEXEOS, developed by Boehringer Ingelheim, is the first and only FDA-approved orally administered targeted therapy for adult patients with unresectable or metastatic non-squamous non-small cell lung cancer (NSCLC). The recent approval is expected to bolster Thermo Fisher's Specialty Diagnostics arm. About TMO's Oncomine Dx Target Test The Oncomine Dx Target Test checks if NSCLC tumors harbor human epidermal growth factor receptor 2 (HER2/ERBB2) tyrosine kinase domain (TKD) activating mutations. It enables multi-biomarker analysis from a single tissue sample to aid treatment decisions in as little as four days. This reduces the need for second biopsies and avoids suboptimal therapy selection in the absence of a complete biomarker report. The test is fully reimbursed by Medicare, as well as by the top 20 commercial payers in the United States. Oncomine Dx Target Test's Global Approvals The Oncomine Dx Target Test received its first approval by the FDA as an NGS CDx in 2017, followed by regulatory approvals in 20 countries for 11 biomarkers and over 20 targeted therapies. The test is reimbursed by government and commercial insurers in the United States, Europe, Japan, South Korea and Israel, covering more than 550 million lives globally. In the United States alone, it is approved for targeted therapies in NSCLC, cholangiocarcinoma (CC), astrocytoma (AC) and oligodendroglioma (OG), anaplastic thyroid cancer (ATC), medullary thyroid cancer (MTC) and thyroid cancer (TC). Industry Prospects Favor TMO According to the American Cancer Society, lung cancer is the second most common cancer in both men and women in the United States, with NSCLC accounting for about 85-90% of all lung cancer cases. Research further indicates that roughly 2-4% of NSCLC patients carry a HER2 mutation. With lung cancer cases continuing to rise, the global market for NSCLC treatments is expected to expand significantly, reaching $66.04 billion by 2032 at a CAGR of 10.3% from 2024 to 2032 (per Fortune Business Insights). Another Development by TMO Thermo Fisher recently announced the FDA approval for Oncomine Dx Express Test on the Ion Torrent Genexus Dx Integrated Sequencer as an in vitro diagnostic (IVD) assay for use as a companion diagnostic (CDx) for Dizal's ZEGFROVY (sunvozertinib) and in tumor profiling. Offerings by TMO's Competitors In the oncology space, Thermo Fisher faces competition from some prominent MedTech players. These companies are also making notable developments in their respective businesses. An expanding NGS oncology portfolio is helping Illumina ILMN drive the revolution in cancer genomics. The company's market-leading TruSight Oncology assay, TSO 500, continues to see increased utilization and broader adoption. In February, the company announced a new single-cell offering for CRISPR research with applications in oncology, immunology and drug target discovery. In 2024, the FDA approved its in vitro diagnostic (IVD) TSO Comprehensive test and its first two companion diagnostic (CDx) indications to rapidly match patients to targeted therapies. This year, Illumina is set to roll out TSO 500 v2, a new version that includes hundreds of genes across all variant classes and immuno-oncology biomarkers in a single assay from one sample, to facilitate therapy selection research. A rapidly expanding liquid biopsy and NGS-based testing portfolio is positioning Guardant Health GH as a leader in precision oncology. The company's flagship Guardant360 test has been recently enhanced with the Guardant Infinity platform, enabling a single blood draw to provide comprehensive tumor profiling, confirm the absence of actionable mutations and determine ER/PR/HER2 status. Regulatory milestones include approvals for Guardant360 CDx as a companion diagnostic in the United States, Japan and Singapore, covering multiple cancer targets such as EGFR and HER2 mutations. Its pipeline also includes the FDA-approved Shield blood test for colorectal cancer screening, offering a non-invasive alternative to colonoscopy. Exact Sciences' EXAS flagship screening product, the Cologuard test, is a non-invasive, stool-based DNA (sDNA) screening test that utilizes a multitarget approach to detect DNA and hemoglobin biomarkers associated with colorectal cancer and pre-cancer. The company's precision oncology portfolio also offers the Oncotype DX Breast Recurrence Score test to identify patients who are most likely to benefit from chemotherapy, as well as those who may receive no clinical benefit from chemotherapy. Its Oncotype DX Colon Recurrence Score test is a multi-gene test for predicting recurrence risk in patients with stage II and stage III A/B colon cancer to enable an individualized approach to treatment planning.

Immutep Limited (IMMP) Receives Positive FDA Feedback on Future Clinical Development of Eftilagimod Alfa

Immutep Limited (NASDAQ:IMMP) is among the 12 Best Australian Stocks to Buy Right Now. On August 5, the company shared that it had received positive feedback from the U.S. FDA on the future clinical development of eftilagimod alfa (efti) for first-line treatment of head and neck squamous cell carcinoma patients with CPS <1. A line of biopharmaceutical products on a laboratory shelf waiting to be tested. The feedback stems from encouraging data from the TACTI-003 Phase 2b trial evaluating efti with MSD's anti-PD-1 KEYTRUDA (pembrolizumab). Immutep Limited (NASDAQ:IMMP) said that the FDA acknowledged the potential of the combination to address the high unmet need in patients with CPS <1 and supports its further development. Marc Voigt, CEO of Immutep Limited (NASDAQ:IMMP), shared the following remarks on the development: 'We are pleased with the FDA's feedback and guidance that underscores the high unmet need of head and neck cancer patients whose PD-L1 expression level is below one. The FDA feedback positions Immutep to evaluate options for future collaborative clinical development paths to bring a new, effective and safe treatment option to this underserved patient population.' Looking ahead, Immutep Limited (NASDAQ:IMMP) also outlined paths for future clinical development. This would include a randomised registrational trial evaluating the combination against standard-of-care therapy, or lead a smaller single-arm study on about 70-90 patients, followed by a confirmatory randomised study building on the existing findings. While we acknowledge the potential of IMMP as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.
