List of Peptide Therapies Companies in Texas - 4

Chrysalis BioTherapeutics, Inc. is a privately held biopharmaceutical company developing regenerative drugs that mimic the body’s natural signals to activate endothelial progenitor cells and stem cells to stimulate tissue repair and restore normal tissue function. Chrysalis BioTherapeutics was incorporated in Delaware in 2012 to develop innovative peptide therapeutics to save lives and improve life’s quality. Chrysalis’ lead drug candidate, TP508, was initially developed to accelerate healing of dermal and musculoskeletal injuries. It proved to be especially effective in promoting healing of diabetic foot ulcers in early human clinical trials and is under development as a treatment for mass casualty injuries and burns. Chrysalis has demonstrated that TP508 mitigates effects of radiation exposure. Chrysalis is therefore collaborating with US government agencies to develop TP508 as a nuclear countermeasure to combat acute and delayed radiation syndromes and to mitigate damaging effects of brain cancer radiation therapy.

Marker Therapeutics, Inc., a clinical stage immuno-oncology company, engages in the development and commercialization of various T cell-based immunotherapies and peptide-based vaccines for the treatment of hematological malignancies and solid tumor indications. Its MultiTAA-specific T cell technology is based on the expansion of non-engineered tumor-specific T cells that recognize tumor associated antigens and kill tumor cells expressing those targets. The company’s MultiTAA-specific T cell therapies include autologous T cells for the treatment of lymphoma, multiple myeloma, and various solid tumors; and allogeneic T cells for the treatment of acute myeloid leukemia and acute lymphoblastic leukemia. It is also developing TPIV100/110, which is in Phase II clinical trial for the treatment of breast cancer; and TPIV200 that is in Phase II clinical trial for the treatment of breast and ovarian cancers.
