Key Market Challenges

Heterogeneity of PD-L1 Expression

Tumor heterogeneity makes it challenging to obtain a representative tissue sample for testing. A biopsy from one area of a tumor may yield different results from another, potentially leading to inaccurate assessments of a patient's likelihood to respond to immunotherapy. This inconsistency can result in patients receiving suboptimal treatment or being excluded from potentially beneficial therapies due to misleading test results.

The lack of a standardized approach for PD-L1 biomarker testing exacerbates the issue of heterogeneity. Different pharmaceutical companies and diagnostic manufacturers may use their own proprietary tests and scoring systems, making it challenging to establish uniform criteria for PD-L1 positivity. This lack of standardization can lead to inconsistencies in test results across laboratories and hinder the comparability of data in clinical trials.

The heterogeneous nature of PD-L1 expression adds complexity to treatment decisions. Clinicians must carefully consider the location and extent of PD-L1 expression within a tumor, as well as the potential presence of immune cells in the tumor microenvironment. This complexity can delay treatment initiation and complicate the selection of the most appropriate immunotherapy regimen for individual patients.

In some cases, PD-L1 expressions may be present but go undetected due to sampling limitations. Patients with low or focal PD-L1 expression may be classified as negative, leading to missed opportunities for immunotherapy. Underdiagnosis can negatively impact patient outcomes and limit the effectiveness of immune checkpoint inhibitors.

Cost-Effectiveness

One of the primary obstacles to the widespread adoption of PD-L1 testing is the high cost associated with certain testing methods, such as immunohistochemistry (IHC) and next-generation sequencing (NGS).
