First-in-Human Phase I Study of MP0250, a First-in-Class DARPin Drug Candidate Targeting VEGF and HGF, in Patients With Advanced Solid Tumors.
PURPOSE: A first-in-human study was performed with MP0250, a DARPin drug candidate. MP0250 specifically inhibits both vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) with the aim of disrupting the tumor microenvironment. PATIENTS AND METHODS: A multicenter, open-label, repeated-dose, phase I study was conducted to assess the safety, tolerability, and pharmacokinetics of MP0250 in 45 patients with advanced solid tumors. In the dose-escalation part, 24 patients received MP0250 as a 3-hour infusion once every 2 weeks at five different dose levels (0.5-12 mg/kg). Once the maximum tolerated dose (MTD) was established, 21 patients were treated with a 1-hour infusion (n = 13, 8 mg/kg, once every 2 weeks and n = 8, 12 mg/kg, once every 3 weeks) of MP0250 in the dose confirmation cohorts. RESULTS: In the dose-escalation cohort, patients treated with 12 mg/kg MP0250 once every 2 weeks experienced dose-limiting toxicities. Therefore, MTD was 8 mg/kg once every 2 weeks or 12 mg/kg once every 3 weeks. The most common adverse events (AEs) were hypertension (69%), proteinuria (51%), and diarrhea and nausea (both 36%); hypoalbuminemia was reported in 24% of patients. Most AEs were consistent with inhibition of the VEGF and HGF pathways. Exposure was dose-proportional and sustained throughout the dosing period for all patients (up to 15 months). The half-life was about 2 weeks. Signs of single-agent antitumor activity were observed: 1 unconfirmed partial response with a time to progression of 23 weeks and 24 patients with stable disease, with the longest duration of 72 weeks and a median duration of 18 weeks. CONCLUSION: MP0250 is a first-in-class DARPin drug candidate with suitable tolerability and appropriate pharmacokinetic properties for further development in combination with other anticancer therapies

Phase I/II study of cetuximab in combination with cisplatin or carboplatin and fluorouracil in patients with recurrent or metastatic squamous cell carcinoma of the head and neck.
PURPOSE: This was an open, randomized, multicenter, phase I/II study to investigate the safety and tolerability of cetuximab in the first-line treatment of recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS: Treatment comprised cetuximab (initial dose 400 mg/m2 with subsequent weekly doses of 250 mg/m2) in combination with 3-week cycles of either cisplatin (100 mg/m2) or carboplatin (area under the curve, 5), each in combination with a 5-day infusion of fluorouracil (FU) at escalating doses of 600, 800, and 1,000 mg/m2/d. The study was divided into two phases: A, the first two cycles (6 weeks) focusing on the safety and tolerability of combination therapy; and B, the remaining time for those benefiting from therapy until disease progression or intolerable toxicity. RESULTS: Fifty-three patients were enrolled onto the study. The incidence of dose-limiting toxicities in phase A was acceptable. The most common grade 3/4 adverse events in both groups were leucopenia (38%), asthenia (25%), vomiting (14%), and thrombocytopenia (15%), which are consistent with the known safety profiles of cetuximab, cisplatin/carboplatin, and FU. The overall response rate among patients was 36%, with no clear trend toward an increased efficacy at the highest dose of FU, and no impact of the concomitant chemotherapy regimens on cetuximab pharmacokinetics. CONCLUSION: The combination of cetuximab, cisplatin/carboplatin, and FU was reasonably well tolerated and active in recurrent/metastatic SCCHN, and merits additional investigation. An FU dose of 1,000 mg/m2/d in combination with cisplatin or carboplatin can be recommended for additional studies.Clinical Trial, Phase IClinical Trial, Phase IIJournal ArticleMulticenter StudyRandomized Controlled Trialinfo:eu-repo/semantics/publishe
