Phase 1 Trial Begins for Immunotherapy Vaccine for Persistent Prostate Cancers

Phase 1 Trial Begins for Immunotherapy Vaccine for Persistent Prostate Cancers
An open-label, multicenter Phase 1 clinical trial has begun to evaluate the safety and immunogenicity of Panacea Pharmaceuticals' PAN-301-1, a nanoparticle immunotherapy vaccine that targets HAAH-positive cancer cells in patients with persistent prostate cancer. The first patient has been dosed, and participants are being enrolled in Alabama, California, Nebraska, and South Carolina. HAAH, which stands for human aspartyl (asparaginyl) β-hydroxylase, is a protein required for fetal development, but its expression is silenced at birth. Studies have reported, however, that some cancers are able to express HAAH, and it participates in cancer cell growth, motility, and invasiveness. The protein is found in more than 20 types of cancer, and its expression is associated with poor prognosis. Its specificity to cancer cells has made it a target for therapies. "HAAH provides a new potential treatment pathway for patients living with persistent prostate cancer, and with the enrollment of the first patient at our center, we are eager to understand the safety and immunogenicity for PAN-301-1 to address this unmet medical need in cancer diagnosis and treatment," lead investigator Luke Nordquist, MD, of GU Research Network in Omaha, Neb., said in a press release. PAN-301-1 consists of a nanoparticle with hundreds of copies of an HAAH fragment. It induces an HAAH-specific antibody response and stimulates immune cells to target the protein. In preclinica

    How can we find out more about the trials.
    A friend and I are traveling down similar paths although his is a little advanced over mine. My cancer is still responding to Xtandi with a PSA level of 0.49, while my friends PSA has been elevated for several weeks and appears to have spread to his liver. He is hesitant to start chemo, but is being told by his doctor that that is his best course of treatment.
    Any advice about your trials would be much appreciated.
    Thanks Herschell Atkinson

    Herschell Atkinson check out Click “advanced search” and include the type of cancer you have under “conditions”, and recruitment “open studies”. You can also filter by state and country. Look through the results and check the inclusion/exclusion criteria for studies you think you may qualify for, and there should be a contact listed if you find a clinical trial you are interested in.

    Need info on where in sc they are doing trials . Father has prostate cancer . And nothing else will work. Hormone therapy not working last PSA was 2500. Looking for a miracle
