Find Clinical Drug Pipeline Developments & Deals by SQZ Biotechnologies
Under the collaboration, SQZ Biotechnologies will regain full clinical development and future commercialization rights for its programs including, SQZ-eAPC-HPV, based on antigen presenting cells (APCs) created by the SQZ platform and targeting HPV 16 positive tumors.
SQZ-AAC-HPV are derived from RBCs engineered with the Cell Squeeze® technology, designed to take advantage of the natural physiological process of aged RBC clearance by resident APCs in lymphoid organs which primes endogenous T cells to potentially drive antitumor activity.
The SQZ® eAPC platform is the company’s second-generation cell therapy platform which simultaneously delivers five different mRNAs—each encoding for a different protein which plays a part in stimulating key T cell activation signals.
SQZ-eAPC-HPV are derived from PBMCs, which are primarily composed of monocytes, T cells, B cells, and NK cells, and engineered with various mRNA encoding for multiple target antigens and immuno-stimulatory signals, including CD86 and membrane-bound IL-2 and IL-12.
Data, published in Frontiers in Immunology, demonstrated that Cell Squeeze® SQZ-AAC platform can be used to generate AACs by engineering RBCs with antigen and adjuvant that can drive antigen-specific activation of T cells both in mouse in vivo and human in vitro systems.
SQZ-APC-HPV (SQZ-PBMC-HPV) is company’s APC autologous cell therapy clinical candidate and is derived from peripheral blood mononuclear cells, primarily composed of monocytes, T cells, B cells, and NK cells, and engineered tumor specic E6 and E7 peptide antigens.
SQZ-PBMC-HPV is an autologous cell therapy candidate comprised of SQZ-engineered antigen presenting cells (APCs) designed to induce CD8 T cell responses against HPV16.
SQZ-PBMC-HPV is being evaluated in a Phase 1/2 clinical trial for the treatment of HPV16+ advanced or metastatic solid tumors. Patients must be positive for the human leukocyte antigen serotype HLA-A*02.
The data published, demonstrated that TACs can induce multiple key mechanisms of antigen-specific tolerance in various model systems, including deletion of autoreactive T cells, energy, and expansion of regulatory T cells capable of bystander suppression.
