Stanford APBI Trial
Clinical Trial
Overview
Intraoperative Radiotherapy (IORT) is one of three approaches used for accelerated, partial breast irradiation at Stanford.
Accelerated, partial breast irradiation (APBI) is a potentially important new way to incorporate radiotherapy in the treatment of women with breast cancer.
Currently, women with breast cancer who undergo a lumpectomy typically have 6 1/2 weeks of radiation to the entire affected breast after surgery. Accelerated, partial breast irradiation (APBI) changes this approach in two ways. It shortens the treatment time from 6 1/2 weeks to between 1 to 5 days, and reduces the treatment area from the entire breast to the area of the breast immediately around the lumpectomy site. This is the part of the breast where most cancers are likely to recur.
In many ways APBI is to current whole breast radiotherapy what a lumpectomy is to a mastectomy. The goal is to use a less invasive more focused treatment without compromising survival.
APBI has been used in limited trials in several hundred patients over the last 10 years. These trials show that in properly selected breast cancer patients APBI worked just as well as whole breast radiotherapy. In the initial studies, investigators relied on the placement of many catheters in the breast tissue (interstial brachytherapy). Newer techniques will hopefully provide the same good results but will deliver the radiation in faster and/or more convenient ways. This could increase interest in APBI and allow additional clinical trials that test the safety and effectiveness of the newer approaches. These newer approaches could increase quality of life for many women with breast cancer.
Investigators at Stanford University Medical Center are currently offering an IRB approved clinical trial that uses three new approaches for APBI. These three approaches are:
Intraoperative Radiotherapy (IORT) - 1 day
Intracavitary Brachytherapy (MammoSite) - 5 days
3-D Conformal/External Beam Radiotherapy - 5 days
The Stanford trial is led by Dr. Frederick Dirbas, Assistant Professor of Surgery, and by Dr. Donald Goffinet, Professor of Radiation Oncology. For further information about the trial please contact Janelle Maxwell or Triona Dolphin at (650) 498-7740.
A Study of TAS0728 in Patients With Solid Tumors With HER2 or HER3 Abnormalities
This is a First-in-Human (FIH), 2-part, Phase 1/2, open-label, multicenter study design to evaluate the safety, tolerability, PK, pharmacodynamics, PGx, and efficacy of TAS0728. This study consists of Phase 1 and Phase 2 components in subjects with advanced solid tumors with HER2 or HER3 overexpression, amplification, or mutation who have progressed despite standard therapy or for which no standard therapy exists, particularly urothelial cancer, biliary tract cancer, metastatic breast cancer, non-small cell lung cancer and colorectal cancer.
Stanford is currently not accepting patients for this trial.
Intervention(s):
- drug: TAS0728
Eligibility
Inclusion Criteria:
1. Male or females with an age ≥ 18 years.
2. Subjects with histological- or cytological-confirmed, advanced cancer, who have
progressed on (or not been able to tolerate) standard therapy or for whom no standard
anticancer therapy exists
1. For Phase 1, only subjects HER2 or HER3 molecular/genetic alterations will be
enrolled.
2. For Phase 2a, subjects with one of the following tumor types will be enrolled:
i. Urothelial cancer with HER2 or HER3 mutation ii. Biliary tract cancer with HER2 or
HER3 mutation iii. Breast cancer with HER2 or HER3 mutation iv. Breast cancer with
HER2 amplification or overexpression v. NSCLC with HER2 or HER3 mutation vi. CRC with
HER2 mutation or amplification vii. Other tumors with HER2
mutation/amplification/overexpression or HER3 mutation (gastric/GEJ, endometrial).
3. At least 1 measurable lesion for solid tumor
4. Is able to take medications orally (e.g., no feeding tube).
5. Able to agree to and sign informed consent and to comply with the protocol
6. Has adequate organ function
Exclusion Criteria:
1. Has a serious illness or medical condition(s)
2. Has received treatment with any proscribed treatments within specified time frames
prior to study drug administration
3. Impaired cardiac function or clinically significant cardiac disease
