简要总结
Background:
ETBX-011, ETBX-061, and ETBX-051 are cancer vaccines. Their goal is to teach the immune system to target and kill cancer cells. The vaccines target 3 proteins found in many types of cancer. Researchers think targeting all 3 proteins in unison will have the best results.
Objective:
To test the safety of combining ETBX-011, ETBX-061, and ETBX-051 and their effects on the immune system.
Eligibility:
People ages 18 and older with advanced cancer that has not responded to standard therapies
Design:
Participants will be screened with:
Medical history
Physical exam
Blood, urine, and heart tests
Scan: They will lie in a machine that takes pictures of the body.
Participants will receive the 3 vaccines through 3 shots under the skin every 3 weeks for 3 doses, then every 8 weeks for up to 1 year. They will have blood and urine tests at each vaccine visit. They will have scans and other measurements of their tumor after 9 weeks and then at their vaccine visits every 8 weeks.
Participants will keep a diary of symptoms at the injection site.
Participants will have a visit 90 days after their final treatment. This will include a physical exam and blood and urine tests. If they have any ongoing side effects, they will be followed until these end or are not changing.
After this visit, they will be called every 3 months for the first year, every 6 months for the next 2 years, then every 12 months for another 2 years to see how they are doing.
Participants will have the option to enroll in a long-term follow-up study.

详细描述
Background:
- The overall goal of the current project is to expand our immunotherapeutic approach for the treatment of advanced cancer employing a multi-targeted approach.
- Therapeutic cancer vaccines targeting overexpressed proteins offer a potential method to activate T cells against tumors.
- A novel adenovirus based vaccine targeting three (3) human tumor associated antigens (TAA), carcinoembryonic antigen (CEA), mucin-1 (MUC1), and brachyury, respectively has demonstrated anti-tumor cytolytic T cell responses in pre-clinical animal models of cancer.
Objectives:
-To determine the overall safety and recommended phase 2 dose of a combination of three immunotherapeutic vaccines (ETBX-011/ETBX-061/ETBX-051), when administered subcutaneously (SC) to subjects with advanced solid tumors

结局指标
主要结局
Recommended Phase 2 Dose (RP2D)
时间窗: RP2D was based upon evaluation of DLTs. Participants were followed for DLTs from the first dose of vaccine for 3 weeks.
RP2D is defined as ≤ 1 of 6 of the initial 6 subjects who experience a dose limiting toxicity (DLT), than this dose level will be defined as the RP2D. A DLT is defined as any Grade 3 or greater toxicity that is possibly related to the vaccine and as defined by the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 with the exception of transient (≤ 24 hours) Grade 3 flu-like symptoms or fever, which is controlled with medical management (≤ 24 hours) Grade 3 fatigue, skin reactions or rash, headache, nausea, emesis that resolves to Grade ≤ 1 or asymptomatic grade 3 amylase/lipase elevation.
Number of Participants With Serious and Non-serious Adverse Events
时间窗: Date treatment consent signed to date off study, approximately 16 months and 6 days.
Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
次要结局
- Number of Participants Who Achieve an Objective Confirmed Complete or Partial Response Assessed by the Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)(Approximately 3.5 months)
- Number of Patients With Disease Control (Confirmed Response or Stable Disease (SD)) Lasting for at Least 6 Months(up to 6 months)
- Progression-free Survival (PFS)(up to 12 months)
- Overall Survival (OS)(up to 12 months)
