European Support for Innovative Lung Cancer Treatment with RYBREVANT® and ENHANZE®

Positive Development in Lung Cancer Treatment

Halozyme Therapeutics, a biopharmaceutical firm known for its innovative drug delivery technologies, achieved a significant milestone in the treatment of advanced non-small cell lung cancer (NSCLC). On February 3, 2025, the Committee for Medicinal Products for Human Use (CHMP), part of the European Medicines Agency, issued a favorable opinion recommending the extension of marketing authorization for a new subcutaneous formulation of RYBREVANT® (amivantamab). This innovative therapy, developed in concert with ENHANZE® technology, is designed for patients with specific EGFR mutations, notably exon 19 deletions and exon 21 L858R substitutions. Moreover, it serves as a monotherapy for patients whose tumors harbor exon 20 insertion mutations after other treatments have failed.

The subcutaneous formulation represents not only a scientific advancement but also a significant improvement in the patient experience. Traditionally administered via infusion, RYBREVANT® combined with lazertinib can now be delivered in approximately five minutes, addressing the critical issue of treatment burden. Dr. Helen Torley, the CEO of Halozyme, expressed optimism about this development, highlighting the potential of the one-time injection to greatly reduce adverse infusion reactions, thus improving patient compliance and comfort.

Clinical evidence supporting this recommendation stems from the Phase 3 PALOMA-3 study, which demonstrated the efficacy and safety of the subcutaneous formulation compared to intravenous delivery methods. With the results from this pivotal trial, the therapeutic combination stands to change the landscape of treatment for advanced EGFR-mutated NSCLC.

Background on ENHANZE® Technology

Halozyme’s ENHANZE® platform employs recombinant human hyaluronidase PH20 (rHuPH20) to enhance the absorption of injected drugs. This approach allows for subcutaneous delivery of medications, enabling faster administration and decreased complications related to IV therapies. With over a million patients impacted worldwide, ENHANZE® is not only transforming traditional administration but also expanding treatment options across various conditions, including oncology and autoimmune diseases.

Partnerships with notable companies like Johnson & Johnson, Roche, and Pfizer reflect the broad applicability and importance of this technology. The ongoing collaboration consists of using ENHANZE® within their respective drug delivery systems, addressing unmet medical needs and simplifying patient logistics.

Future Implications

Looking ahead, if the European Commission grants full approval based on the CHMP’s recommendation, it may set a precedent for regulatory bodies in other regions to follow suit. This could prompt discussions around re-evaluating existing drugs within oncology frameworks and introduce a wave of reform in therapeutic delivery methodologies. As the demand grows for patient-friendly treatment protocols, advancements like RYBREVANT® and ENHANZE® will likely play a crucial role in how modern oncology addresses complex challenges such as those presented by advanced NSCLC.

In summary, the integration of RYBREVANT® in a subcutaneous form combined with ENHANZE® represents a meaningful leap forward for patients battling lung cancer. This innovation showcases Halozyme’s commitment to improving treatment outcomes and fostering more efficient delivery methods, paving the way for exciting future advancements in the biopharmaceutical landscape.
