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 is essential for normal tissue and even more so for solid malignancies. At present, inhibition of tumor angiogenesis is a major focus of anticancer drug development. Bevacizumab, a humanized antibody against VEGF, was the first antiangiogenic agent to be approved for advanced non-small cell lung cancer, breast cancer and colorectal cancer. The most commonly observed adverse events are hypertension, proteinuria, bleeding and thrombosis. Sunitinib, a small molecule blocking intracellular VEGF, KIT, Flt3 and PDGF receptors, which regulate angiogenesis and cell growth, is approved for the treatment of advanced renal cell cancer (RCC) and malignant gastrointestinal stromal tumor. The most frequent adverse events include hand-foot syndrome, stomatitis, diarrhea, fatigue, hypothyroidism and hypertension. Sorafenib, an oral multikinase inhibitor, is approved for the second-line treatment of advanced RCC and upfront treatment of advanced hepatocellular carcinoma. Most common adverse events with sorafenib are dermatologic (hand-foot skin reaction, rash, desquamation), fatigue, diarrhea, nausea, hypothyroidism and hypertension. More recently, cardiovascular toxicity has increasingly been recognized as a potential adverse event associated with sunitinib and sorafenib treatment. Elderly patients are at increased risk of thromboembolic events when receiving bevacizumab, and potentially for cardiac dysfunction when receiving sunitinib or sorafenib. The safety of antiangiogenic drugs is of special concern when taking these agents for longer-term adjuvant or maintenance treatment. Furthermore, newer investigational antiangiogenic drugs are briefly reviewed.

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.

Pancreatic cancer is one of the most lethal and resistant to treatment of solid tumors. Combination therapies with various types of drugs against pancreatic cancer have been extensively investigated. Endostatin is a potent endogenous inhibitor of angiogenesis, which may be administered in combination with various chemotherapeutic agents in the treatment of several types of cancer. To the best of our knowledge, this phase I trial was the first clinical study to determine the tolerance, safety and efficacy of M2ES, a novel polyethylene glycosylated recombinant human endostatin, administered concurrently with full-dose gemcitabine in patients with inoperable, locally advanced or metastatic pancreatic adenocarcinoma. A total of 16 patients were treated with gemcitabine (1,000 mg/m2 on days 1, 8 and 15) and M2ES (5-45 mg/m2 on days 1, 8, 15 and 21) of each 28-day cycle. In 15 evaluable patients, the stable disease rate (SDR) was 40% (95% CI: 11.9-68.1%). In particular, a 75% SDR was observed in 3 out of 4 patients with a M2ES dose level of 7.5 mg/m2. The most noticeable M2ES-related adverse events observed during the trial were grade 2 liver function abnormalities (6.3%) and grade 1 skin rash (6.3%). No dose-limiting toxicity was observed in any patients from all the dose levels. Therefore, there was no increased toxicity associated with the addition of M2ES to gemcitabine and this combination was well tolerated.

Apatinib is an oral TKI with antiangiogenic properties, and it is currently approved for the treatment of advanced gastric cancer in China. This agent has also been tested in other human solid tumors, including non-small cell lung cancer (NSCLC). Since the combination of chemotherapy and an antiangiogenic agent has been shown to be a feasible strategy in NSCLC, it is conceivable that a similar approach combining apatinib with chemotherapy may yield clinical activity. With this in mind, we investigated the efficiency of apatinib in combination with pemetrexed or docetaxel in advanced NSCLC. We treated a total of 20 patients with metastatic NSCLC adenocarcinoma with apatinib in combination with either pemetrexed or docetaxel from January 2016 to March 2017. The performance status of these patients was 0 or 1. All of these patients had been previously treated with two or more lines of treatment and had experienced disease progression prior to study enrollment. The overall objective response rate (ORR) was 30%, with 6 patients who had partial response (PR), 10 patients who had stable disease (SD), and 4 patients who had progressive disease (PD). The main adverse events were skin rash, hypertension, palmar-plantar erythrodysesthesia syndrome, diarrhea, and fatigue. Nearly 30% of patients required interruption of treatment as a result of toxicity. Our study demonstrated that apatinib combined with systemic cytotoxic chemotherapy has clinical efficacy in patients with disease-refractory metastatic NSCLC and provides evidence for further studies investigating apatinib-based combination regimens.
