A phase Ib clinical trial of PV701, a milk-derived protein extract, for the prevention and treatment of oral mucositis in patients undergoing high-dose BEAM chemotherapy.
Despite the best available agents to prevent mucositis, most patients receiving high-dose chemoradiotherapy regimens experience severe mucositis, and new therapies are needed. In this study, we evaluated the safety and tolerability of a milk-derived growth factor extract (PV701 mouthwash) intended to prevent oral mucositis (OM) after carmustine, etoposide, cytosine arabinoside, and melphalan (BEAM) chemotherapy. PV701 mouthwash (15 mL x 13.5 mg/mL) was administered 6 times a day for 12 days, from day--6 to day +5, to patients with lymphoma, who were given BEAM on day--6 to day--2, with autologous stem cells infused on day 0. Dose de-escalation of PV701 was planned if dose-limiting toxicities occurred. The severity and duration of OM, the duration of enteral/parenteral feeding, the requirement for intravenous opiates, and admission to intensive care were recorded. Outcomes were also compared with those of historical control patients. Nine patients received PV701 13.5 mg/mL. PV701 was well tolerated, and no dose-limiting toxicities were observed. Compared with 89 historical controls, the 9 PV701-treated patients had significantly less frequent grade 2 or 3 OM ( P=.0006) and had grade>or=3 OM for an estimated 5 fewer days ( P=.0003). There was a reduction in the need for enteral/parenteral feeding ( P=.012), its duration ( P=.010), and its frequency ( P=.022) and in the duration of intravenous opiates ( P=.0006). We conclude that PV701 mouthwash is readily administered with minimal side effects at a dose of 1215 mg/d, and further investigation of this agent is warranted.
