Impact of COVID-19 on HER2-Positive Breast Cancer Market Growth

Prior to the pandemic, the HER2-positive breast cancer segment was on an upward trajectory driven by expanding screening programs, improved diagnostic capabilities, and growing adoption of targeted therapies. Routine mammography screenings and oncology clinic visits were carried out without significant barriers. Clinical trial enrollment proceeded steadily, with investigators worldwide collaborating on novel antibody–drug conjugates and combination regimens. Manufacturing and distribution channels for biologics and supportive care agents were operating under normal conditions, ensuring steady patient access.

When COVID-19 struck, measures taken to curb virus transmission led to delays in routine screening appointments, diagnostic biopsies and treatment initiation. Many early-stage HER2-positive cases went undetected for months, resulting in more patients presenting at advanced stages. Hospitals and infusion centers temporarily repurposed oncology wards for pandemic response, causing treatment scheduling backlogs. Clinical trials experienced site shutdowns and slower enrollment. Supply chain disruptions affected raw material shipments for monoclonal antibodies; in some regions, import restrictions delayed the arrival of critical therapies. Patient reluctance to visit healthcare facilities further compounded gaps in care continuity.

As restrictions eased, oncology providers rapidly embraced telemedicine consultations to triage symptoms and maintain follow‑up. Dedicated “oncology safe zones” and staggered infusion schedules minimized exposure risk. Remote monitoring tools for cardiac function—critical for trastuzumab-based regimens—were piloted to allow at-home data collection. Clinical trial sponsors adopted decentralized approaches, shipping oral investigational products to patients and conducting virtual site visits.

Future strategies must prioritize resilient supply chains with multiple manufacturing sites and improved inventory forecasting. Stakeholders should invest in hybrid trial models that combine in‑clinic assessments with decentralized elements, reducing enrollment barriers in outbreak settings. Expanding digital health platforms will support real‑time safety monitoring and patient engagement. Strengthening collaboration between payers, providers and research organizations can ensure rapid adaptation of reimbursement policies and trial protocols during any subsequent global health crisis.
