Osimertinib mesylate

RYBREVANT FASPRO™ is approved across all indications of RYBREVANT® (amivantamab-vmjw) SAN DIEGO, Dec. 18, 2025 /PRNewswire/ -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) (Halozyme) today announced that Johnson & Johnson has received approval from the U.S. Food and Drug Administration (FDA) for RYBREVANT FASPRO™ (amivantamab and hyaluronidase-lpuj), which is co-formulated with ENHANZE® for patients with epidermal growth factor receptor (EGFR)-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC).1 RYBREVANT FASPRO™ is approved across all indications of RYBREVANT® (amivantamab-vmjw) and represents the first and only subcutaneously (SC) administered targeted therapy for patients with EGFR+ mNSCLC. Compared to intravenous (IV) delivery, RYBREVANT FASPRO™ significantly reduced administration time from several hours to approximately five minutes and demonstrated an approximately fivefold reduction in administration-related reactions (ARRs) (13 percent in SC vs 66 percent in IV arm). "Formulated with our leading ENHANZE drug delivery technology, RYBREVANT FASPRO™ has the potential to make administration faster and more convenient for patients and their families compared to intravenous administration," said Dr. Helen Torley, president and chief executive officer of Halozyme. "By reducing administration times and simplifying the treatment experience, ENHANZE-formulated products could also support efficiencies for healthcare providers and lower costs for the healthcare system. This approval underscores ENHANZE's role in delivering meaningful clinical and economical value for patients, providers and payers." Based on the results from the Phase 3 PALOMA-3 study (NCT05388669), RYBREVANT FASPRO™ delivered consistent results to RYBREVANT®, meeting both co-primary pharmacokinetic (PK) endpoints as measured by amivantamab levels in the blood [Ctrough on Cycle (C) 2 Day (D) 1 or C4D1 and C2 area under the curve (AUCD1-D15)].1,2 For more information on this approval, please view Johnson & Johnson's press release issued on December 17, 2025.

Johnson & Johnson on Tuesday said the FDA approved Rybrevant Faspro (amivantamab/hyaluronidase-lpuj), marking the first subcutaneous (SC) therapy authorised for patients with EGFR-mutated non–small-cell lung cancer (NSCLC).The approval of the SC formulation — earlier turned down by the agency last year owing to manufacturing site deficiencies — encompasses all NSCLC indications previously covered by intravenous (IV) Rybrevant (amivantamab-vmjw), including combination with Lazcluze (lazertinib) in the first-line setting.The company noted SC dosing of the EGFRxMET-targeting bispecific antibody represents a significant advancement in patient convenience and healthcare resource utilisation — with administration time dropping from several hours to five minutes, alongside a nearly five-fold reduction in administration-related reactions and a lower incidence of venous thromboembolism.Highlighting the limited treatment options available to patients with EGFR-mutated NSCLC, Biljana Naumovic, president of solid tumours at J&J Innovative Medicine, said: "Now, patients are gaining greater access to this transformative treatment, as well as the tools needed to proactively manage common dermatological effects."The latest approval builds on data from the Phase III PALOMA-3 study, which showed that Rybrevant Faspro delivered consistent results to the IV Rybrevant, meeting both co-primary pharmacokinetic endpoints assessed by blood drug levels. Data presented at the American Society of Clinical Oncology (ASCO) meeting last year showed the SC arm achieved longer duration of response, improved progression-free survival, and longer overall survival (OS) versus IV. Additionally, median OS was notably higher when combined with Lazcluze, with 65% of Rybrevant Faspro recipients alive at 12 months versus 51% receiving Rybrevant.Key growth driverWith AstraZeneca’s Tagrisso (osimertinib) posing a serious threat in the EGFR-mutated NSCLC space, analysts had previously said the SC formulation was critical for the J&J drug to win back market share from Tagrisso. Rybrevant — and the much-awaited Rybrevant Faspro — are being viewed as major growth engines for J&J’s oncology business, with cancer drug sales projected to reach $50 billion annually by 2030. Factoring in the SC variant, the drugmaker estimated a $5-billion peak revenue for the Rybrevant franchise last year.
