Efficacy

Portrazza (necitumumab) for Lung Cancer

Portrazza (necitumumab) is a monoclonal antibody designed for the treatment of a specific type of lung cancer known as squamous non-small cell lung cancer (NSCLC). It targets the epidermal growth factor receptor (EGFR), which is often overexpressed in squamous NSCLC cells. The efficacy of Portrazza was evaluated in a clinical trial that included patients with advanced squamous NSCLC who had not received prior chemotherapy for their advanced disease. When used in combination with gemcitabine and cisplatin, Portrazza demonstrated an improvement in overall survival compared to chemotherapy alone. However, it is important to note that Portrazza is not indicated for patients with non-squamous NSCLC or those with EGFR mutation-positive NSCLC.

Alecensa (alectinib) for Lung Cancer

Alecensa (alectinib) is an oral medication used to treat non-small cell lung cancer (NSCLC) that is anaplastic lymphoma kinase (ALK)-positive, as detected by an FDA-approved test. Alectinib is a tyrosine kinase inhibitor that specifically targets the ALK fusion gene, which can drive the development of lung cancer. The efficacy of Alecensa has been demonstrated in several clinical trials, where it has shown to be effective in shrinking tumors in patients with ALK-positive NSCLC. In particular, Alecensa has been found to have a high central nervous system (CNS) activity, which is significant as ALK-positive NSCLC patients have a high incidence of brain metastases.

Both Portrazza and Alecensa are examples of targeted therapies that have expanded the treatment options for specific subtypes of lung cancer. While Portrazza targets the EGFR in squamous NSCLC, Alecensa targets the ALK fusion gene in ALK-positive NSCLC. These targeted approaches allow for more personalized treatment plans based on the genetic characteristics of a patient's cancer, potentially leading to better outcomes and fewer side effects than traditional chemotherapy.

It is critical for healthcare providers to identify the appropriate patient population for these therapies through biomarker testing. The selection of patients based on the presence of EGFR overexpression for Portrazza and ALK rearrangements for Alecensa is essential to maximize the efficacy of these drugs. As with any cancer treatment, the efficacy of Portrazza and Alecensa must be weighed against their potential side effects, and their use should be guided by a thorough understanding of the individual patient's condition and the specific characteristics of their lung cancer.
