About

A Phase I Study of Dose Escalation and Dose Expansion To Evaluate the Safety、Tolerability、Pharmacokinetics and Preliminary Efficacy of Paclitaxel Micelles for Injection in Chinese Patients With Advanced Solid Tumor.

Full description

The study will be conducted in two parts. The first part is dose escalation and the second part is dose Expansion.During the course of dose escalation, 18-27 subjects will be enrolled to assess the safety、tolerability、pharmacokinetics、preliminary efficacy ,and determine the dose-limiting toxicity (DLT) and maximum tolerated dose(MTD) of Paclitaxel Micelles for Injection, and explore phase II clinical dosages. The second part will be adjusted according to the result of the first part. It will be divided into 4 groups, including advanced breast cancer group, ovarian cancer group, non-small cell lung cancer group and gastric cancer group, with 20 subjects in each group, to further evaluate the safety, tolerance, PK and anti-tumor activity of paclitaxel micelle.

Enrollment: 98 estimated patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Participants are required to meet all the criteria below in order to be included in the trial:

  6. No radiotherapy, chemotherapy, immunotherapy or other anti-tumor therapy (such as experimental drugs, biological agents, Chinese herbal medicine, etc.), surgical treatment (except diagnostic biopsy), or complete recovery from previous surgery within 4 weeks prior to enrollment, and no surgical operation was planned during the study period.

Participants (including partners) who are willing to follow reliable contraceptive measures during the study and until 3 months after the last dosing（such as intrauterine devices [IUDs], birth control pills or condoms）.Women of child-bearing age must be negative for serum HCG within 14 days prior to study enrolment and must be non-lactating。
  11. Participants with voluntarily signature Informed Consent Form (ICF) before the test, and have a full understanding of the test content, process and possible adverse reactions.
  12. Participants with good compliance, were available for follow-up, and volunteered to comply with study regulations.

Exclusion criteria

• Eligible participants must not meet any of the following exclusion criteria:

  1. Patients with the toxicity of previous antitumor therapy did not return to grade 1 or below (CTCAE 5.0 grade >1, excluding toxicity such as alopecia and other toxicity judged by investigators to be of no safety risk).
