CHMP Issues Positive Opinion for Subcutaneous RYBREVANT®(amivantamab) Co-Formulated with ENHANZE® for the Treatment of Patients with Advanced EGFR-Mutated Non-Small Cell Lung Cancer

SAN DIEGO, Feb. 3, 2025 /PRNewswire/ -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) (Halozyme) today announced that Janssen-Cilag International NV, a Johnson & Johnson company, received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency recommending an extension of marketing authorisation for a subcutaneous (SC) formulation of RYBREVANT® (amivantamab) in combination with LAZCLUZE® (lazertinib) for the first-line treatment of adult patients with advanced non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R substitution mutations, and as a monotherapy for the treatment of adult patients with advanced NSCLC with activating EGFR exon 20 insertion mutations after failure of platinum-based therapy.

"We are pleased that the subcutaneous formulation of amivantamab, which was developed with our ENHANZE drug delivery technology, was recommended for approval in Europe," said Dr. Helen Torley, president and chief executive officer of Halozyme. "The data that support the recommendation could represent a very compelling proposition for patients with the approximate five-minute administration time and five-fold reduction in infusion related reactions."

The CHMP positive opinion is supported by positive results from the Phase 3 PALOMA-3 study (NCT05388669). For more information on the study and its findings, please view Johnson & Johnson's press release issued today.

Subcutaneous amivantamab is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20), Halozyme's ENHANZE® drug delivery technology.
