Updated my short summary of Leronlimab: Next Generation Monoclonal Antibody Therapy in Cancer Indication. (Summary sending to docs asking them to consider helping a patient to apply for leron through compassionate use.)
Many thanks to ohm for taking a look and offering vital additions.
Figured there might be other folks out there in the same unfortunate, speeding boat so pasting the ugly version below. (If you would like the pretty Word version with working links, just DM me and I can email it. Still working to fix links in a PDF version.)

Leronlimab: Next Generation Monoclonal Antibody Therapy in Cancer Indication
How it Works: Leronlimab (PRO 140) is an investigational humanized IgG4 monoclonal antibody that blocks CCR5, a cellular receptor that is important in HIV infection, tumor metastases, and other diseases, including NASH.
Leronlimab inhibits angiogenesis by downregulating VEGF, anti-trafficking of tumor cells, increase in tumor fighting NKT cells, debases DNA repair, stops the recruitment of Tregs to tumor sites (Tregs promote tumor immunity), downregulates IL-13 a tumor protectant and IL-4 (IL-4 promotes tumor immunity), upregulates IFN-gamma promoting tumor cell death and downregulates PD-L1. Downregulates CDK2/4/6, cyclin D1, cyclin E, and PCNA which are implicated in tumor cell growth. Upregulates p27 and p53 which are both tumor suppressors.
In the setting of cancer, research has shown that CCR5 may play a role in tumor invasion, metastases, & tumor microenvironment control. Increased CCR5 expression is an indicator of disease status in several cancers. Published studies have shown that blocking CCR5 can reduce tumor metastases in laboratory & animal models of aggressive breast and prostate cancer. Leronlimab reduced human breast cancer metastasis by more than 98% in a murine xenograft model. CytoDyn has conducting several human clinical trials to establish proof of concept and efficacy in patients with cancer.
Taken Along with Current Treatment: The study treatment, Leronlimab, is a once per week subcutaneous injection. It can be used along with one’s current cancer treatment.
Major possible benefits:
o Reducing metastasis: as CCR5/CCL5 is the axis that white blood cells use for chemotaxis
o Restoring Tumor microenvironment: as blocking CCR5 can repolarize White Blood Cells
o In CCR5 over-expressing cancers: CCR5 over-expression seems to play a role in chemo and therapeutic resistance; Blocking CCR5 seems to increase effectiveness of therapies
Impeccable Safety Profile: Lack of SAEs, well tolerated, in more than one thousand patients over five years, in a population as fragile as HIV patients. The FDA has granted a Fast Track designation to CytoDyn for two potential indications of leronlimab for critical illnesses. Leronlimab has completed nine clinical trials in over 800 people and met its primary endpoints in a pivotal Phase 3 trial. Cancer trials include a Phase 2 compassionate use study in metastatic triple-negative breast cancer (being granted Fast Track designation in May 2019) and a Phase 2 basket study on patients with CCR5 locally advanced or metastatic sold tumor.
Rapid Results:
o Trials are indicating drops of CTC and reduction of EMT cells and putative metastic cells.
o Leronlimab may help in advanced TNBC. Blocking CCR5 is being found to possibly reduce metastasis and reduce the ability of tumor cells to maintain the micro-environment that enables them to avoid other chemotherapies and the body's immune system.
