Herceptin Hylecta (trastuzumab/hyaluronidase-oysk)

While service delivery (manpower, facility, consumables) and productivity loss remained cheaper in home care, drug cost is the dominant factor of overall expenditure in trastuzumab delivery. At current drug prices, outpatient IV trastuzumab administration is the cost-saving option, compared with home care SC trastuzumab.

This retrospective analysis suggests that using a slow bolus injection with an infusion pump may reduce local adverse reactions following subcutaneous administration of pertuzumab and trastuzumab in patients with HER2-positive breast cancer. The standardized use of infusion pumps could enhance patient comfort, safety, and overall treatment experience.

These findings are particularly relevant to healthcare systems where SC formulations are newly introduced, providing timely evidence to guide patient-centered clinical decision-making. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=637674, identifier CRD42025637674.

Phesgo demonstrated comparable or superior efficacy and favorable safety with markedly improved treatment efficiency in real-world Japanese practice. Phesgo represents a promising alternative to intravenous administration, reducing patient burden and optimizing healthcare resource utilization.

The effects of Herceptin or gabapentin, a THBS4 receptor inhibitor, on subcutaneous tumors were examined in nude mice...In vivo, CAFs suppress HER2 expression of subcutaneous GC tumors and induce Herceptin resistance...THBS4 from CAFs downregulated HER2 (ERBB2) expression in GC cells. Thus, THBS4 receptor inhibitors may be useful in preventing the acquisition of resistance to anti-HER2 therapy.
