ALK targeted therapy

VENTANA anti-ALK (D5F3) Rabbit Monoclonal Primary Antibody* stained with OptiView DAB Detection and Amplification detects the ALK protein that is the target of therapy
Clinical guidelines recommend rapid turnaround for earlier targeted therapies
ALK has comparable sensitivity and specificity relative to FISH
Make more immediate treatment decisions for advanced NSCLC patients by using the VENTANA anti-ALK (D5F3) Assay

Non-small cell lung cancer (NSCLC)

XALKORI^® (crizotinib), ZYKADIA^® and ALECENSA^® (alectinib) and lorlatinib are clinically effective and CE Marked for the treatment of patients with metastatic NSCLC whose tumors are ALK-positive as detected by an FDA-approved testing method for ALK.^{1, 3, 7}

XALKORI (crizotinib) is indicated for the treatment of patients with ALK positive metastatic NSCLC and other kinases¹
ZYKADIA (ceritinib) is indicated for the treatment of patients with ALK-positive metastatic NSCLC who have had no previous treatment, or who have progressed on, or who are intolerant to, crizotinib³
ALECENSA (alectinib) is indicated for the treatment of patients with ALK-positive metastatic NSCLC who have had no previous treatment, or who have progressed on, or who are intolerant to, crizotinib⁷
Lorlatinib is indicated for patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) whose disease has progressed on crizotinib and at least one other ALK inhibitor for metastatic disease; or whose disease has progressed on alectinib or ceritinib as the first ALK inhibitor therapy for metastatic disease¹²

Technical benefits of IHC testing

ALK FISH can present technical challenges in evaluating patient results and offers the potential for false negatives. Recent studies indicate that the VENTANA ALK (D5F3) Assay stained with OptiView DAB Detection and Amplification is sensitive and specific for determination of ALK status, and a better alternative to ALK FISH. There are reports of ALK IHC-positive, FISH-negative patients benefitting from treatment with XALKORI, ZYKADIA or ALECENSA. ^8,9,10,11

In one study, van der Wekken et al. “…found that dichotomous ALK-IHC is superior to ALK-FISH on small biopsies and fine-needle aspirations (FNA) to predict tumor response and survival to crizotinib for patients with advanced NSCLC.” ⁷

	VENTANA ALK (D5F3) Assay with OptiView DAB Detection and Amplification	ALK FISH
Easy to score	Binary (+/-) scoring Any strong positive staining in any number of cells is positive for ALK	Requires a dual color scoring algorithm Requires 50 enumerable cells and specific cutoff ratios to be calculated
Faster turnaround times	4.5 hours, fully automated Routine IHC testing	12+ hours, semi-automated Typically batch or send-out testing
Brightfield vs. fluorescent staining	Standard brightfield microscope Fully archivable results Full visibility of tumor morphology	Requires a fluorescent microscope Staining and signal fade over time Loss of tissue morphology

Testing for lung cancer

Clinical guidelines recommend routine testing for genetic mutations in all adenocarcinomas, including ALK EML4 gene rearrangement. Testing is recommended immediately after establishing histology and is required prior to initiating targeted therapy for a patient. The current approved methods for testing include IHC and FISH.

Lung cancer is the leading cause of death

Lung cancer is the most prevalent form of cancer in the world. Each year, more than 1.8 million new cases are diagnosed. Lung cancer also has the highest mortality rate. Five-year survival rates are as low as 18%.

Adenocarcinoma, a subset of NSCLC, is the most common, comprising approximately 40% of all lung disease.^5,6

Intended use

VENTANA anti-ALK (D5F3) Rabbit Monoclonal Primary Antibody (VENTANA anti-ALK (D5F3)) is intended for laboratory use in the detection of the anaplastic lymphoma kinase (ALK) protein in formalin-fixed, paraffin-embedded non-small cell lung carcinoma (NSCLC) tissue stained with the BenchMark IHC/ISH instruments. It is indicated as an aid in identifying patients eligible for treatment with XALKORI^® (crizotinib), ZYKADIA^® (ceritinib), or ALECENSA^® (alectinib) or lorlatinib.

This product should be interpreted by a qualified pathologist in conjunction with histological examination, relevant clinical information, and proper controls.

This product is intended for in vitro diagnostic (IVD) use.
