Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 75 Years|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.

This is a prospective, randomized, 2-arm, multicenter study to compare the safety and efficiency of T-DM1 + Afatinib versus T-DM1 in HER2-positive breast cancer patients with active refractory brain metastases. This study will be divided into two phases. The purpose of Phase I is to find out the highest dose of Afatinib that can be given safely with T-DM1. 3 ~ 24 eligible subjects will be enrolled in the study. The purpose of Phase II is to find out whether the dose of Afatinib with T-DM1 determined in Phase I will keep subjects from getting worse for a period of time. The estimated ORR is 17.9 percent in the control group, hypothesis Afatinib can improve the prognosis of subjects, so objective respond rate (ORR) of experimental group is increased by 30 percent, with alpha = 0.025 (unilateral), beta = 0.1. The ratio of the experimental group and control group is 1:1, assuming a 5 percent loss rate. As a result, calculating by PASS 11 software, approximately 106 subjects will be enrolled, with 53 cases in the experimental group, and 53 cases in the control group.
Experimental: T-DM1 + Afatinib
Trastuzumab emtansine (T-DM1) : 3.6 mg/kg IV Day 1 every 21 days. Afatinib: the highest dose of Afatinib with T-DM1 found in Phase I, po every day
Active Comparator: T-DM1
Trastuzumab emtansine (T-DM1) :3.6 mg/kg IV Day 1 every 21 days.
Drug: - Afatinib
Dose-escalation Phase (Phase I) - Afatinib Dose-escalation will proceed on the basis of dose limiting toxicity (DLT) during Cycle 1 starting at 20 mg/day. Dose level 1: 20 mg/day; Dose level 2: 30 mg/day; Dose level 3: 40 mg/day; Dose level 4: 50 mg/day. Dose-evaluation Phase (Phase II) - Patients will receive the highest dose of Afatinib with T-DM1 found in Phase I as study therapy
Drug: - T-DM1
Dose-escalation Phase (Phase I) - Trastuzumab emtansine (T-DM1) will be given at 3.6 mg/kg IV Day 1 every 21 days. Dose-evaluation Phase (Phase II) - Trastuzumab emtansine (T-DM1) will be given at 3.6 mg/kg IV Day 1 every 21 days.
