About this study

Official title: A Pilot Study of the Safety, Tolerability, Feasibility and Efficacy of Anti-PD-1 or Anti-PD-L1 in Combination With a Personalized Neo-antigen Vaccine in Advanced Solid Tumors (NeoPepVac)

The primary objective is to assess tolerability and safety of a personalized neo-antigen vaccine containing up to 15 peptides derived from somatic mutation of the individual patient's cancer, with CAF09b as adjuvant. The vaccine formulation will be administered in combination with an approved anti-PD-1 or anti-PD-L1 inhibitor to patients with advanced solid tumors. The endpoint is the characterization of adverse events (AE) assessed by CTCAE 4.0.

The secondary objective is feasibility to manufacture a personalized neo-antigen vaccine within 6 weeks of enrolment with the PIONEER pipeline, and to evaluate the immune response before, during and after treatment with the personalized neo-antigen vaccine. And evaluate the effect on the immune response correlated to dose escalation of peptides in the vaccine. The endpoint is to evaluate the induction of adaptive immune responses to the personalized neo-antigen vaccine measured by functional assays and peptide-MHC multimer stainings.

The tertiary objective is to evaluate the clinical efficacy of the treatment. The endpoints will be objective responses (OR), progression free survival (PFS) and overall survival (OS).

Read the detailed description

Cancer immunotherapy has shown the ability to improve the survival of patients with multiple types of advanced cancers. The human immune system can recognize the products of somatic genetic alterations in tumors, or neo-antigens, which are not expressed on normal cells. These neoantigens are an attractive immune target because their selective expression on tumors can minimize immune tolerance as well as the risk of side effects such as autoimmune reaction.

Although neoantigens are ideal targets for cancer immunotherapies, most neoantigens arise from unique mutations and are not shared between individual patients. Thus, neoantigen-directed immunotherapy will need to be personalized. Novel technical advances in next-generation sequencing allow fast and systematic prediction of cancer neoantigens for each individual patient. Initial attempts of therapeutic cancer vaccination targeting individual neo-antigens have proven non-toxic and met their immunological endpoints.

In this study investigators will use the proprietary platform PIONEER for fast and accurate identification of a neo-antigen vaccine tailored to each individual patient. The vaccine, based on 5-15 peptides derived from a patient's tumor individual neo-antigens, will be formulated with a novel adjuvant to strengthen CD8+ T cell immunity to cancer. Immune checkpoint inhibitors targeting PD-1 or PD-L1 will be administered both before, during and after vaccination to unleash the activity of vaccine-induced immune responses.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing EVAX-01-CAF09b in people with Malignant Melanoma, Metastatic and Non Small Cell Lung Cancer Metastatic, run by Herlev Hospital at 2 sites in Denmark.

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 18 inclusion and 22 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: status not confirmed, as of the sponsor's last update on 11 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Denmark. 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?

Results are not available in the source record.

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 and type of reported adverse events (time frame: 0-100 weeks). 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 NCT03715985.

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 11 Jan 2022.
