There is considerable evidence to support an immunopathogenic basis of psoriasis. However, changes such as altered angiogenesis have also been implicated in the pathogenesis of psoriasis. AE-941 (Neovastat; Aeterna Laboratories, Quebec City Quebec, Canada) is a naturally occurring product currently in clinical investigation that blocks two main mechanisms of angiogenesis activation, namely, vascular endothelial growth factor and matrix metalloproteinase. We hypothesized that psoriasis could be modulated by inhibiting the neovascularization of psoriatic plaques. We conducted a randomized dose-comparison trial to evaluate the safety and potential therapeutic benefit of AE-941, administered orally to patients with psoriasis. Forty-nine patients with psoriasis were enrolled and assigned to receive AE-941 at 30, 60, 120, or 240 mL/d for 12 weeks. Patients were followed up for another 12-week period. Improvement in the Psoriasis Area and Severity Index (PASI) score was observed in 50%, 41.7%, and 30.8% of the patients receiving 240, 120, and 60 mL/d, respectively. No patients receiving a dosage 30 mL/d showed a PASI score improvement. A statistically significant improvement with increasing dose was observed for the PASI score, severity of itch, and the physician's global assessment. The most commonly reported nonserious drug-related adverse events affected the gastrointestinal system in 12 of 49 patients (primarily nausea, diarrhea, vomiting, flatulence, and constipation) and the skin and appendages in 4 of 49 patients (primarily acne and rash). This randomized phase I/II study provides evidence that the antiangiogenic agent AE-941 offers a new therapeutic approach to the management of psoriasis.

Angiogenesis has been shown to be important in tumor growth and metastasis. Thalidomide, an oral sedative, has recently been found to inhibit angiogenesis. We therefore set out to ask whether thalidomide can be used as therapy for breast cancer. In a mouse model of breast cancer, we found that thalidomide alone did not suppress tumor growth. However, mice treated with thalidomide in combination with cytoxan and adriamycin had significantly smaller tumors than those given the two chemotherapeutic agents alone (3,432 +/- 303 mm(3) versus 4,643 +/- 203 mm(3), p = 0.0005). We proceeded to administer thalidomide together with chemotherapy to seven breast cancer patients in the context of a Phase I trial. Side effects attributed to thalidomide were minimal, and included constipation and a rash. We concluded that an approach at cancer therapeutics combining an antiangiogenic agent such as thalidomide with conventional chemotherapy may be feasible and deserves further studies.

Toxicities commonly associated with antiangiogenic agents include hypertension, proteinuria, wound-healing complications, bleeding or hemorrhage, thromboembolic events, hypersensitivity reactions, and gastrointestinal perforation; however, toxicities most often attributed to chemotherapy include nausea, vomiting, diarrhea, constipation, fatigue, neuropathy, mucositis, hand-foot syndrome, hypersensitivity reactions, and myelosuppression. Patients with metastatic colorectal cancer (mCRC) who receive an antiangiogenic agent in combination with chemotherapy may experience toxicities related to both chemotherapy and the antiangiogenic agent. If possible, evidence-based interventions should be used for the management of toxicities. Patient education about expected toxicities and optimal toxicity management can promote the optimal use of therapy to improve survival and quality of life. Oncology nurses are well positioned to educate patients and their families on anticipated treatment and management of side effects. This article summarizes the incidence of toxicities associated with the antiangiogenic biologic agents aflibercept and bevacizumab, in combination with chemotherapy for patients with mCRC, and provides strategies for managing these toxicities based on clinical practice guidelines.
