Successful desensitization with cetuximab after an infusion reaction to panitumumab in patients with metastatic colorectal cancer

Management of infusion-related reactions in cancer therapy: strategies and challenges

Several anticancer therapies have the potential to cause infusion-related reactions (IRRs) in the form of adverse events that typically occur within minutes to hours after drug infusion. IRRs can range in severity from mild to severe anaphylaxis-like reactions. Careful monitoring at infusion initiation, prompt recognition, and appropriate clinical assessment of the IRR and its severity, followed by immediate management, are required to ensure patient safety and optimal outcomes. Lack of standardization in the prevention, management, and reporting of IRRs across cancer-treating institutions represents not only a quality and safety gap but also a disparity in cancer care. The present article, supported by recently published data, was developed to standardize these procedures across institutions and provide a useful tool for health care providers in clinical practice to recognize early signs and symptoms of an IRR and promptly and appropriately manage the event.

Incidence and associated factors of cetuximab-induced hypersensitivity infusion reactions in 1392 cancer patients treated in four French areas: a possible association with Lyme disease?

BACKGROUND

Previous studies have observed an increased incidence of Cetuximab-induced hypersensitivity infusion reactions (CI-IRs) in the southeastern states of the USA. Tick's bites were suspected of generating cross-reactions between cetuximab and alpha-gal. This study aims was to describe the incidence and associated risk factors of CI-IRs, in the French areas chosen according to their Lyme disease incidence.

PATIENTS AND METHODS

A retrospective chart review was conducted on patients that received cetuximab infusion from January 2010 to June 2019 in 4 French areas with different Lyme disease incidence rates.

RESULTS

Of 1392 patients, 117 (8.4%) experienced a CI-IR, including 68 severe (grade 3 or 4) reactions (4.9%). This CI-IR incidence was significantly higher in the Lyme disease high-risk area than in the other areas (13.2% versus 7.1%, 8.1% and 6.4%; P = 0.016). Sex (P = 0.53), premedication (P = 0.91), primary cancer location (P = 0.46) and chemotherapy regimen type (P = 0.78) had no impact on CI-IR incidence in the overall population. In the head and neck squamous cell carcinoma (HNSCC) patient subgroup, CI-IRs were significantly more frequent in the high-risk area (16.4% versus 6.7%, 7.1% and 7.0%; P = 0.0015).

CONCLUSION

This study suggests that patients treated in the French area with the highest incidence of Lyme disease are at a higher risk of CI-IRs.

Successful rechallenge with cetuximab after an infusion related reaction to panitumumab in a patient with locally advanced rectal cancer

Incidence of infusion related reaction (IR) is more common with cetuximab (Cmab) than with panitumumab (Pmab). Although little is known about rechallenge IR with monoclonal antibodies, we experienced a successful rechallenge to Cmab after IR to Pmab. A 67-year-old female patient was scheduled for chemotherapy with mFOLFOX6 plus Pmab against unresectable advanced rectal cancer in the hope of tumor shrinkage. On the first administration of Pmab, she complained of dyspnea with shortness of breath and wheezing, even after premedication with steroids and antihistamines. Her reaction was judged as Grade 2 IR to Pmab. For the next course, we tried Cmab. No IRs were observed. Since then, she has undergone seven further courses of treatment, followed by surgical resection. The patient benefited from administration of Cmab after experiencing IR to Pmab, suggesting this treatment to be an option for patients of this type who experience IR to Pmab.

Successful desensitization of a patient with cetuximab hypersensitivity: A case report

BACKGROUND

Severe hypersensitivity reaction is a dangerous adverse drug reaction in patients receiving cetuximab. It requires drug discontinuation and medical management.

CASE DESCRIPTION

A 48-year-old man, previously diagnosed with metastatic colorectal cancer, was admitted for therapy continuation. During the first infusion of cetuximab, the patient experienced acute signs of hypersensitivity reactions. The treatment team decided to administer cetuximab employing the desensitization protocol.

CONCLUSIONS

This study reports a severe hypersensitivity reaction to cetuximab in an adult patient with colorectal cancer. This patient was successfully managed with a new safe and rapid desensitization protocol.

Research progress on common adverse events caused by targeted therapy for colorectal cancer

As targeted drug therapy is increasingly applied in the treatment of colon cancer, understanding and managing the adverse reactions of patients is becoming increasingly important. The present review examines the mechanisms of and adverse reactions to the most commonly used targeted drugs for colon cancer, and discusses methods of coping with these adverse reactions. Approved targeted drugs for metastatic colon cancer include monoclonal antibodies targeting vascular endothelial growth factor (VEGF), including bevacizumab, ziv-aflibercept and regorafenib, and monoclonal antibodies targeting epithelial growth factor receptor (EGFR), including cetuximab and panitumumab. The present review assesses the major adverse effects of these drugs and methods of dealing with reactions to them. VEGF inhibitors primarily result in cardiovascular and kidney problems. Meanwhile, EGFR receptor inhibitors are frequently reported to cause rashes, diarrhea and hypertension, and are reviewed from the point of view of resulting electrolyte disturbances.

Biological agents in gastrointestinal cancers: adverse effects and their management

Biological therapy comprises agents that by virtue of their unique mechanisms of action, are able to specifically incite a response against or target malignant cells. They differ from conventional chemotherapy with regard to mechanisms of action, indications and side effect profile. Biologic agents have revolutionized therapy for a number of malignancies. In the setting of gastrointestinal (GI) malignancies, agents targeting vascular endothelial growth factor (VEGF), human epidermal growth factor receptor 2 (Her2/Neu) and epidermal growth factor receptor (EGFR) have proven to be invaluable additions to chemotherapy. However, these agents bring with them a set of side effects attributable to their unique mechanisms of action. The anti VEGF agents-bevacizumab, aflibercept and ramucirumab, can result in renal and vascular complications such as hypertension, arterial thrombotic events (ATE), proteinuria and GI perforations. The anti EGFR agents classically cause dermatological toxicities, in addition to hypomagnesemia, which can be dose limiting for patients. Trastuzumab, a monoclonal antibody that targets Her2/Neu, is known to cause cardiotoxicity, especially when used with anthracyclines. Use of immunotherapy agents such as nivolumab is associated with the development immune related adverse events (irAEs). The use of these agents is expected to increase over the next few years and it is crucial that patients and practitioners are aware of their adverse effects and current management strategies. This review highlights the adverse events associated with the use of biologic and immunologic therapies in GI cancers, their incidence and current management strategies.

Hypersensitivity and tumor lysis syndrome associated with cetuximab treatment: should we be afraid?

The majority of the chemotherapy agents in use today cause various infusion reactions, from mild flushing to life-threatening events. The frequency of the reported hypersensitivity reactions induced by cetuximab varies between 3% and 22%. It is recommended in the literature to stop the infusion and replace cetuximab with panitumumab in case of hypersensitivity reactions observed during the treatment of colon cancer. Tumor lysis syndrome (TLS) may occur in colorectal cancers with heavy tumor load. Tumor lysis syndrome may be life-threatening. In our patient with widespread bone and liver metastases, treatment continued with cetuximab as a combination therapy with irinotecan in spite of the hypersensitivity and TLS led to a complete treatment response. The complete response observed after 3 months through continued therapy in our patient may present an example supporting treatment with cetuximab in spite of severe reactions.

Review of hypersensitivity reactions to antineoplastic agents

OBJECTIVE

To review the characteristics and management of hypersensitivity reactions caused by antineoplastic agents.

METHOD

We conducted a search in the Pubmed and EMBASE databases for the last 10 years.

RESULTS

Almost all chemotherapeutic agents have the potential to cause hypersensitivity reactions, but some groups have been associated with increased risk, such as platinum compounds, taxanes, asparaginase, monoclonal antibodies and epipodophyllotoxins. The clinical manifestations of these reactions are variable and unpredictable, including symptoms affecting the skin and the pulmonary, cardiac and gastrointestinal systems. The mechanism associated with their development is not yet fully understood. Diagnosis is based on patients' signs and symptoms and skin testing. The management of patients who suffer a hypersensitivity reaction to a chemotherapeutic agent varies with the severity of the reaction, the need to continue treatment, and the availability of alternative therapies.

CONCLUSIONS

Due to a progressive increase in the use of chemotherapeutic agents an increased incidence of hypersensitivity reactions is to be expected. Desensitisation protocols are a noteworthy alternative that make it possible to re-initiate patients' therapy with the causative agent of the hypersensitivity reaction. Their use should be assessed individually, weighing risks and benefits.

Anaphylactic reactions to oligosaccharides in red meat: a syndrome in evolution

OBJECTIVE

While most allergic responses to food are directed against protein epitopes and occur within 30 minutes of ingesting the allergen, recent studies suggest that delayed reactions may occur, sometimes mediated by IgE antibodies directed against carbohydrate moieties. The objective of this review is to summarize the clinical features and management of delayed hypersensitivity reactions to mammalian meat mediated by IgE antibodies to galactose-alpha 1,3-galactose (alpha-gal), an oligosaccharide.

METHODS

A PubMed search was conducted with MeSH terms: galactosyl-(1,3) galactose, oligosaccharides, cetuximab, allergy/hypersensitivity, and anaphylaxis. Reported cases with alpha-gal-mediated reactions were reviewed. This research study was approved by the Institutional Review Board of East Tennessee State University.

RESULTS

Thirty-two cases of adults presenting with red-meat induced allergy thought to be related to oligosaccharides have been reported in the literature so far, making this a rare and evolving syndrome. Most of these patients demonstrated delayed reactions to beef, as was seen in the case reported by us in this manuscript. IgE specific to alpha-gal was identified in most patients with variable response to skin testing with beef and pork. Inhibition studies in some cases showed that the IgE antibodies to beef were directed towards alpha-gal in the meat rather than the protein. The patients often reported history of tick bites, the significance of which is unclear at present. Reactions to cetuximab, a monoclonal antibody, are mediated by a similar mechanism, with IgE antibodies directed against an alpha-gal moiety incorporated in the drug structure.

CONCLUSION

Alpha-gal is an oligosaccharide recently incriminated in delayed anaphylactic reactions to mammalian meats such as to beef, pork, and lamb. It appears that anaphylactic reactions to the anti-cancer biological agent, cetuximab, may be linked mechanistically to the same process. More studies are required to understand the underlying molecular basis for these delayed reactions in specific, and their broader implications for host defense in general.

Adverse events associated with anti-EGFR therapies for the treatment of metastatic colorectal cancer

The epidermal growth factor receptor (EGFR), a member of the ErbB family of receptor tyrosine kinases, plays an important role in the control of cell growth and differentiation. Disruption of its signaling leads to neoplastic cell proliferation, migration, stromal invasion, resistance to apoptosis, and angiogenesis.

EGFR is overexpressed in a variety of solid tumors, including colorectal cancer (CRC), and its overexpression is associated with poorer prognosis. One class of agents that is currently used to target EGFR in the treatment of metastatic CRC (mCRC) is the monoclonal antibodies. While the monoclonal antibody EGFR inhibitors lack many of the severe side effects commonly observed with cytotoxic chemotherapy, they are associated with a set of unique dermatological toxicities. This paper reviews the safety profile of the anti-EGFR monoclonal antibodies cetuximab and panitumumab in the treatment of mCRC.

Hypersensitivity reactions associated with platinum antineoplastic agents: a systematic review

Platinum-containing chemotherapy agents (cisplatin, carboplatin, oxaliplatin) have been approved in the first-line setting of numerous malignancies, such as ovarian, bladder, head and neck, colorectal, and lung cancer. Their extensive use over the last decade has led to a significant increase in the incidence of hypersensitivity reactions, which are defined as unforeseen reactions whose signs and symptoms cannot be explained by the known toxicity of these drugs. Skin rash, flushing, abdominal cramping, itchy palms, and back pain are common symptoms. Cardiovascular and respiratory complications can prove fatal. Multiple pathogenetic mechanisms have been suggested. Hypersensitivity usually appears after multiple infusions, suggesting type I allergic reactions; however, other types of hypersensitivity also seem to be implicated. Several management options are available to treating physicians: discontinuation of chemotherapy, premedication, prolonging of infusion duration, desensitization protocols, and replacement with a different platinum compound after performing skin tests that rule out cross-reactions among platinum agents.

Adecatumumab: an anti-EpCAM monoclonal antibody, from the bench to the bedside

IMPORTANCE OF THE FIELD

In developing new anticancer drugs, the identification of relevant targets is a key issue of growing importance. Ideally, an anticancer drug target should be specific to cancer cells, in order to both increase efficacy and decrease toxicity of the compound.

AREAS COVERED IN THIS REVIEW

Epithelial cell adhesion molecule (EpCAM) is a membrane protein with proto-oncogenic properties that is expressed in a number of endothelium-derived cancers and is a promising anticancer drug target. Adecatumumab is a monoclonal, fully human IgG1 antibody that targets EpCAM, development of which is at present reaching Phase III trials.

WHAT THE READER WILL GAIN

From a review of literature, we here update the rationale for using EpCAM as an anticancer target for monoclonal antibodies, with a special focus on adecatumumab. The fully human nature of adecatumumab is also discussed to put the drug in perspective with other related anti-EpCAM monoclonal antibodies, such as edrecolomab and catumaxomab. Adecatumumab studies are recapitulated, in order to provide the reader with a comprehensive view of the development of this promising anticancer agent.

TAKE HOME MESSAGE

Adecatumumab is a promising fully human monoclonal antibody targeting EpCAM which is expressed in almost all adenocarcinomas and its activity is not dependent of K-Ras status.
