Anthem Blue Cross California Zaltrap (ziv-aflibercept) Form

Overview

This document addresses the use of Zaltrap (ziv-aflibercept). Zaltrap is a recombinant fusion protein consisting of vascular endothelial growth factor (VEGF)-binding portions that is primarily used to treat metastatic colorectal cancer. The FDA approved indication for Zaltrap is, in combination with 5-fluorouracil, leucovorin, irinotecan (FOLFIRI), for treatment of metastatic colorectal cancer (mCRC) that is resistant to or has progressed following an oxaliplatin-containing regimen.

Clinical criteria

The National Comprehensive Cancer Network® (NCCN) provides additional recommendations with a category 2A level of evidence for treatment of CRC. NCCN notes that no data exists that suggest activity of FOLFIRI plus Zaltrap in individuals who have progressed on FOLFIRI plus bevacizumab; FOLFIRI + Zaltrap has only shown activity when given to FOLFIRI-naïve individuals.

Within the guidelines, NCCN recommends that appendiceal adenocarcinoma be treated with chemotherapy according to colon cancer guidelines. Similarly, anal adenocarcinoma may be treated according to guidelines for rectal cancer.

In addition, NCCN notes that studies have shown that combination with more than one biologic agent is not associated with improved outcomes and can cause increased toxicity, specifically regarding the addition of Erbitux (cetuximab) or Vectibix (panitumumab) to a bevacizumab-containing regimen (Tol 2009, Hecht 2009).

NCCN strongly recommends against the use of therapy involving concurrent combination of an anti-EGFR agent and an anti-VEGF agent.

Individuals using Zaltrap should be monitored for hemorrhage, gastrointestinal perforation, and compromised wound healing. It should be suspended for at least 4 weeks prior to elective surgery and not resumed for at least 4 weeks following major surgery and until surgical wound is fully healed.

Other Uses

NCCN also provides 2A recommendations for Zaltrap in combination with an irinotecan-based regimen for treatment of mCRC that has previously been treated with fluoro-pyrimidine without irinotecan or oxaliplatin. However, studies cited in this recommendation only investigated Zaltrap after previous treatment with an oxaliplatin-based regimen (Van Cutsem 2012).

Definitions and Measures

• Adenocarcinoma: Cancer originating in cells that line specific internal organs and that have gland-like (secretory) properties.
• Anal cancer: Cancer originating in the tissues of the anus; the anus is the opening of the rectum (last part of the large intestine) to the outside of the body.
• Colon cancer: Cancer originating in the tissues of the colon (the longest part of the large intestine). Most colon cancers are adenocarcinomas that begin in cells that make and release mucus and other fluids.
• Colorectal cancer: Cancer originating in the colon (the longest part of the large intestine) or the rectum (the last several inches of the large intestine before the anus).
• Disease Progression: Cancer that continues to grow or spread.
• Metastasis: The spread of cancer from one part of the body to another; a metastatic tumor contains cells that are like those in the original (primary) tumor and have spread.
• One line of therapy: Single line of therapy.
• Progressive Disease (PD): Cancer that is growing, spreading, or getting worse.
• Rectal cancer: Cancer originating in tissues of the rectum (the last several inches of the large intestine closest to the anus).
• Refractory Disease: Illness or disease that does not respond to treatment.

• Relapse or recurrence: After a period of improvement, during which time a disease (for example, cancer) could not be detected, the return of signs and symptoms of illness or disease. For cancer, it may come back to the same place as the original (primary) tumor or to another place in the body.
• Unresectable: Unable to be removed with surgery.
• Vascular endothelial growth factor (VEGF): A substance made by cells that stimulates new blood vessel formation.

Clinical Criteria
