Официальное название

Evaluation on Open-Labeled and Dose-Escalation Phase I Clinical Study of Safety and Pharmacokinetics of Recombinant Humanized Bispecific Monoclonal Antibody MBS301 for Injection in Treatment of HER2 Positive Recurrent or Metastatic Malignant Solid Tumor

Обзор

This is a phase I study evaluating the safety and pharmacokinetics of MBS301 after intravenous administration in patients with HER-2 positive recurrent or metastatic malignant solid tumors

Вмешательства

• Препарат Recombinant Humanized Bispecific Monoclonal Antibody MBS301
  The patients confirming to the eligibility criteria will be assigned to the 8 dose groups based on the sequence of inclusion. MBS301 will be administered intravenousely on day 1 of each 21-day cycle for each patient.The first intravenous infusion for each patient will be last for 90 minutes.It could be changed to 60 minutes for the subsequent infusions if the drug is well tolerated.
