About this study

Official title: In-Situ Cancer Vaccine: Phase IIA, Open-Label Study to Assess the Safety of AlloStim® Immunotherapy Alone and in Combination With Cryoablation as Third Line Therapy for Metastatic Colorectal Cancer

This is a single center, open label dose frequency escalation study of CryoVax®. personalized anti-tumor vaccine protocol combining the cryoablation of a selected metastatic lesion with intra-lesional immunotherapy with AlloStim®. The in-situ (in the body) cancer vaccine step combines killing a single metastatic tumor lesion by use of cryoablation in order to cause the release of tumor-specific markers to the immune system and then injecting bioengineered allogeneic immune cells (AlloStim®) into the lesion as an adjuvant in order to modulate the immune response and educate the immune system to kill other tumor cells where ever they reside in the body.

Read the detailed description

Colorectal cancer (CRC) ranks as the third most common cancer worldwide. Metastasis is the main reason of death in CRC patients. The current drugs used to treat colorectal cancer provide important treatment options for patients, their limitations including drug resistance, poor efficacy and severe side effects. Development of new therapeutic strategies for KRAS mutant as well as BRAF mutant tumors are therefore highly needed in order to offer a new category of drug (immunotherapy). This study targets the population of mCRC patients that have progressed after two lines of chemotherapy and are not eligible for targeted therapies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AlloStimBiological

    Also called CryoVax

    AlloStim is an activated living CD4+ Th1 memory cell derived from the blood of normal blood donors and intentionally mismatched to the recipient. AlloStim is bioengineered to express high levels of Type 1 inflammatory cytokines (such as interferon-gamma, TNF-alpha, GM-CSF) and immunomodulatory molecules such as CD40L. AlloStim has CD3/CD28-coated microbeads attached to assure activation upon infusion.

  • CryoablationProcedure or surgery

    Percutaneous partial cryoablation of a single metastatic tumor lesion in the liver. The procedure is conducted under CT or ultrasound image-guidance

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AlloStim and Cryoablation in people with Colorectal Cancer Metastatic, run by Mirror Biologics, Inc. at 1 site 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 30 inclusion and 23 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 16 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 phase mean?

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 16 May 2025). 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?

Evaluate the Overall Survival (time frame: from time of signing informed consent for up to 18 months or until death). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02380443, which also lists 8 linked publications.

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 16 May 2025.
