Expanded Access To Neoantigen Synthetic Long Peptide Vaccines in Patients With Local Or Metastatic Solid Tumors

January 13, 2026 updated by: Jaime Leandro Foundation for Therapeutic Cancer Vaccines
This is an intermediate patient expanded access protocol for treatment of patients with local or metastatic solid tumors with a neoantigen synthetic long peptide vaccine.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Available

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Expanded Access

Expanded Access Type

Expanded Access Type

Describes the category of expanded access under U.S. Food and Drug Administration (FDA) regulations. There are three types of expanded access:
  • Individual Patients: Allows a single patient, with a serious disease or condition who cannot participate in a clinical trial, access to a drug or biological product that has not been approved by the FDA. This category also includes access in an emergency situation.
  • Intermediate-size Population: Allows more than one patient (but generally fewer patients than through a Treatment IND/Protocol) access to a drug or biological product that has not been approved by the FDA. This type of expanded access is used when multiple patients with the same disease or condition seek access to a specific drug or biological product that has not been approved by the FDA.
  • Treatment IND/Protocol: Allows a large, widespread population access to a drug or biological product that has not been approved by the FDA. This type of expanded access can only be provided if the product is already being developed for marketing for the same use as the expanded access use.
  • Individual Patients
  • Intermediate-size Population

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

N/A

Description

Patients must satisfy the following criteria to be enrolled in the protocol:

Main Inclusion Criterion:

1. Patient who qualifies for treatment under 21 CFR 312.305 based on treating physician judgment, inability to enroll in study JLF-200, must have received or be ineligible for FDA-approved therapies for their specific cancer type, and an estimated 5-year survival of less than 50%.

Other Inclusion Criteria:

  1. >= 12 years of age.
  2. ECOG performance status ≤ 2 or Karnofsky score of >=70.
  3. Adequate organ function allowing favorable benefit to risk ratio per the treating physician
  4. Systemic corticosteroid therapy is permitted provided dosing is no greater than 4 mg per day (dexamethasone or equivalent) on the day of vaccine administration.
  5. Ability to understand and willingness to sign an IRB approved written informed consent document.

Exclusion Criteria:

  1. History of serious adverse reaction to vaccines such as anaphylaxis, hives, or respiratory difficulty or known allergy to a component of the neoantigen synthetic long peptide vaccine.
  2. Intercurrent illness requiring chronic use of medications that may interfere with rescue medications for treatment of vaccine-related anaphylaxis or attenuate immune response to vaccine treatment (immunosuppressive therapies).
  3. Psychiatric illness or social situations that would limit compliance with study requirements.
  4. History of pre-existing immunodeficiency disorder or autoimmune condition requiring immunosuppressive therapy that would preclude response to vaccine. 5. Females of childbearing potential may participate provided they agree to practice abstinence; and, if heterosexually active, agree to use at least 2 highly effective contraceptive methods throughout the study and for 3 months following the last dose of study drug; and have a negative serum pregnancy test.

6. Females of non-childbearing potential must be post-menopausal or have been surgically sterilized.

7. Male subjects with a female partner of childbearing potential must agree to practice abstinence or to use a physician-approved contraceptive method throughout the study and for 3 months following the last dose of study drug.
