EXTON, PA, Oct. 31, 2025 (GLOBE NEWSWIRE) -- Spherix Global Insights has announced the launch of its latest Market Dynamix™ service, PD-1 Inhibition in Solid Tumors (US) 2025, providing an in-depth analysis and advisory services for the evolving immuno-oncology landscape as the next wave of PD-1 biosimilars and subcutaneous (SC) formulations rapidly approach market entry.
As leading PD-1 inhibitors, including Merck’s Keytruda (pembrolizumab) and BMS’ Opdivo (nivolumab), approach loss of exclusivity, Spherix’s newest Market Dynamix™ study explores physician perceptions, anticipated prescribing shifts, and market readiness for both biosimilar and novel formulation competition within major tumor types, including non–small cell lung cancer (NSCLC), melanoma, renal cell carcinoma (RCC), and other top solid tumor indications.
Study Focus and Methodology
The inaugural 2025 edition of Market Dynamix™: PD-1 Inhibition in Solid Tumors will integrate quantitative insights from 100 U.S.-based oncologists with Spherix’s established market tracking and pipeline intelligence. The research will assess both current treatment algorithms and forward-looking expectations surrounding two critical developments reshaping the checkpoint inhibitor class:
- Biosimilar PD-1 inhibitors (e.g., Amgen’s ABP-206 nivolumab biosimilar): Evaluating oncologist familiarity, perceived clinical equivalence, adoption intent, and expected impact on practice economics and patient access.
- Subcutaneous PD-1 formulations (e.g., Merck’s Keytruda QLEX): Exploring attitudes toward convenience, patient and workflow advantages, and anticipated shifts in site-of-care dynamics.
The study also captures perspectives on:
- PD-1 brand positioning and share forecasts over the next 12 months.
- The evolving influence of biomarker testing requirements (PD-L1, MSI, TMB) on treatment selection.
- Barriers and facilitators shaping uptake of new PD-1 entrants.
- Future treatment preferences and unmet needs in immuno-oncology delivery.
With PD-1 inhibitors continuing to dominate immuno-oncology care, the emergence of biosimilars and SC delivery formats represents a major inflection point for manufacturers, providers, and payers. Spherix’s analysis delivers actionable intelligence and advisory services to inform commercial planning, lifecycle management, and competitive positioning across the solid tumor immunotherapy landscape.
