Brief Summary

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. ...

Outcome Measures

Primary Outcomes (2)

  • Number of Participants With Serious and Non-serious Adverse Events

    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.

    Date treatment consent signed to date off study, approximately 16 months and 6 days.

  • Recommended Phase 2 Dose (RP2D)

    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.

    RP2D was based upon evaluation of DLTs. Participants were followed for DLTs from the first dose of vaccine for 3 weeks.

Secondary Outcomes (4)

  • 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

Other Outcomes (4)

  • Number of Participants With a Positive Mucin-1 (MUC-1) Specific T-Cells Immune Response

    up to week 6

  • Number of Participants With a Positive Carcinoembryonic Antigen (CEA) Specific T-Cells Immune Response

    up to week 6

  • Number of Participants With a Positive Brachyury Specific T-Cells Immune Response

    up to week 6

  • +1 more other outcomes

  • +5 more criteria

You may not qualify if:

  • Pregnant and nursing women. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with combination ETBX-011, ETBX-051, ETBX-061, breastfeeding should be discontinued if the mother is treated with combination ETBX-011, ETBX-051, ETBX-061. These potential risks may also apply to other agents used in this study.
  • There should be a minimum of 4 weeks from any prior investigational drug, chemotherapy, immunotherapy, with the exception of hormonal therapy for prostate and breast cancers, human epidermal growth factor receptor 2 (HER2-) directed therapy for HER2+ breast or stomach cancer (3+ immunohistochemistry (IHC) or fluorescence in situ hybridization (FISH+), drugs targeting epidermal growth factor receptor (EGFR), anaplastic large-cell lymphoma kinase (ALK) or ROS1 in EGFR,ALK, ROS1-mutated lung cancer, respectively, or standard maintenance therapies for any solid tumor under the condition that subjects are on these therapies for at least two months before start of trial treatment.
  • There should also be a minimum of 4 weeks from any prior radiotherapy except for palliative bone directed therapy.
  • Known active brain or central nervous system metastasis (less than 1 month out from definitive radiotherapy or surgery), or seizures requiring anticonvulsant treatment, or clinically significant cerebrovascular accident or transient ischemic attack (\<3 months).
  • Subjects with serious intercurrent chronic or acute illness, such as cardiac or pulmonary disease, hepatic disease, or other illness considered by the Investigator as high risk for investigational drug treatment.
  • Subjects with clinically significant heart disease, such as congestive heart failure (class II, III, or IV defined by the New York Heart Association functional classification), history of unstable or poorly controlled angina, or history (\< 1 year) of ventricular arrhythmia.

  • Subjects on systemic intravenous or oral corticosteroid therapy with the exception of physiologic doses of corticosteroids (less than or equal to the equivalent of prednisone 10 mg/day) or other immunosuppressives such as azathioprine or cyclosporin A are excluded on the basis of potential immune suppression. For these subjects these excluded treatments must be discontinued at least 2 weeks prior to enrollment for recent short course use (less than or equal to 14 days) or discontinued at least 4 weeks prior to enrollment for long term use (\> 14 days). In addition, the use of corticosteroids as premedication for contrast-enhanced studies is allowed prior to enrollment and on study.
