About this study

Official title: A Phase I/IIa Study of SV-BR-1-GM in Metastatic or Locally Recurrent Breast Cancer Patients

This is a single arm, open label study of SV-BR-1-GM, a targeted immunotherapy for breast cancer. Eligible patients will have histological confirmation of breast cancer with recurrent and/or metastatic lesions. The treatment regimen includes a pre-treatment with low-dose cyclophosphamide 2-3 days before the inoculation; inoculation in 4 sites on the thighs and upper back; and post-treatment inoculation of Interferon-alpha-2b into the sites of inoculation ~2 and ~4 days after the inoculation. These is repeated every 2 weeks for one month (3 treatments), then monthly for up to one year. Standard tumor assessments are performed at baseline and then every 2-3 months.

Read the detailed description

This is a single arm, open label study of SV-BR-1-GM in recurrent and/or metastatic breast cancer. The detailed treatment regimen follows:

Pre-Inoculation Regimen:

Cyclophosphamide (Cytoxan) 300 mg/m^2 I.V., 1x only, will be given 48-72 hours before each SV-BR-1-GM inoculation, with an antiemetic of the provider's choice (steroids prohibited). If the patient is not tolerating the cyclophosphamide, a lower dose may be used (e.g. 200 or 150 mg/m^2) or it may be withheld, with the Sponsor's approval.

Innoculation Day Standard Operating Procedures:

  1. Inquire regarding events of past weeks, change in medications, pain scale, ECOG scale, and review of systems.
  2. Check injection sites.
  3. Perform DTH skin test intra-dermally with the SV-BR-1 parent cell line (~1 x 10^6 irradiated tumor cells). Observe about 20 minutes for acute hypersensitivity. Grade III or higher acute hypersensitivity will abort therapy.
  4. Inject SV-BR-1-GM intra-dermally into 4 sites in thighs and upper back (0.5 mL each). Monitor patients for 60 minutes. Vital signs will be assessed and medical attention will be warranted if unstable.

SV-BR-1-GM Preparation \& Inoculation Regimen:

Each inoculation will be administered via intra-dermal injection at the investigational sites. Subjects will receive 15-25 x 10^6 viable, irradiated transfected breast tumor cells in a total volume of 2.0 ml Ringer's lactate. SV-BR-1-GM cells will be irradiated to ensure cell replication incompetency.

SV-BR-1-GM will be divided into four aliquots of 0.5 mL each and injected intra-dermally; one each into the anterior skin of the subject's right and left thighs and over the right and left upper back . Application of anesthetic lidocaine crème may be used if necessary for control of local pain before inoculation. Subjects will be monitored for 60 minutes.

After at least 10 subjects have been treated safely with this regimen, the dose of SV-BR-1-GM may be escalated or decreased in subsequent patients based on the emerging data.

Post-Inoculation Regimen:

2 days (± 1 day) after inoculation, and again 4 days (± 1 day) later after inoculation, the patient will return to the principal investigator's office to receive Interferon-alpha-2b (Merck) in 0.1 mL saline, prepared as follows: These will also be provided by the sponsor and injected intra-dermally to each inoculation site, beneath the thickest area. Again, subjects will be observed about 20 minutes. The DTH response will also be recorded at the 2 days (± 1 day) visit.

This cycle will be performed every 2 weeks for the first month of treatment (3 inoculations), and then every month for up to one year.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Treatment Emergent Adverse Events Occurring in Two or More Patients [Safety]

    To evaluate the number of patients with toxicity events while on SV-BR-1-GM, as defined by the Common Terminology Criteria for Adverse Events (CTCAE)

    Measured: Through study completion, an average of 1 year

Secondary outcomes (5)
  1. Duration of Treatment Emergent Adverse Events [Safety]

    To evaluate the duration of toxicity events while on SV-BR-1-GM, as defined by CTCAE

    Measured: Through study completion, an average of 1 year

  2. Number of Participants With an Adverse Event Related to SV-BR-1-GM Administration [Safety]

    To evaluate the number of participants with an adverse event related to SV-BR-1-GM administration, as defined by CTCAE

    Measured: Through study completion, an average of 1 year

  3. Objective Tumor Response Rate

    Objective response rate (ORR), defined as complete response (CR) or partial response (PR) per response evaluation criteria in solid tumors (RECIST) and immune-related RECIST (iRECIST) criteria.

    Measured: Through study completion, an average of 1 year

  4. Rate of Non-progression of Tumors

    Non-progressive rate, defined as CR, PR or stable disease (SD) per RECIST and iRECIST criteria

    Measured: Through study completion, an average of 1 year

  5. Durability of Tumor Response

    Durability of response, as defined as complete response (disappearance of all tumors), partial response (30% or greater reduction in the sum of diameters of target lesions (tumors) with stable disease in non-target lesions) or stable disease (less than 20% increase in the sum of diameters of target lesions with no new lesions appearing) by evaluating those patients eligible to complete the optional treatments from 9-12 months

    Measured: Through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing SV-BR-1-GM, Cyclophosphamide and Interferon-alpha-2b in people with Breastcancer and Breast Neoplasm, run by BriaCell Therapeutics Corporation at 5 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Jan 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Treatment Emergent Adverse Events Occurring in Two or More Patients [Safety] (time frame: Through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2021.
