Symthera, Inc. is a biopharmaceutical company whose mission is to develop treatments for Metastatic Cancer. Symthera’s focus is on the rapid development and commercialization of innovative pharmaceutical products for the treatment of Metastatic Cancer.


Our Approach

Targeted therapies have been shown to provide benefit to patients by selectively targeting disease-associated proteins. Overall impact on disease by such approaches has, however, failed to provide robust impact as single-agent therapies. Symthera has developed a proprietary approach to identify consensus amino acid sequences shared by, or unique to disease-associated proteins to validate disease-related targets and simultaneously identify drug leads that impact that network. By alignment of multiple sequences, Symthera's approach will disclose unique, cryptic consensus sequences between disease-associated proteins. Symthera has established an effective means to characterize target interaction profile and to identify peptide drug candidates via a proprietary microarray-based screening approach, coupled with high-efficiency peptide synthesis capabilities and characterization of disease impact early in the drug discovery process using animal models. Identification of agents that appropriately affect multiple targets is not readily addressed by traditional drug discovery approaches. Via Symthera's disease-network drug discovery approach, stretches of shared sequences provide an advanced starting point for identification of peptide drug candidates that impact the disease network rather than a single target. Peptide drugs have demonstrated efficacy on the market or in the clinic for a range of diseases and can be delivered by multiple routes including oral, intranasal, intramuscular and intrathecal administration. The approach is geared to generate well-characterized drug candidates with a high success rate and clear path to clinical and commercial application.

Our Focus

Symthera's drug leads, biological peptides, address the immediate shortcomings of existing medication in the following ways: Protein derivatives - Low toxicity natural products - High specificity therapeutics - Minimal side effects - Immune modulators - Inducers of immune tolerance. Symthera’s focus is on the rapid development and commercialization of innovative pharmaceutical products for the treatment of Metastatic Cancer.

About Us

Drug Discovery Company

Symthera is a drug discovery company with a unique technology platform capable of identifying novel treatments for diseases with unmet medical needs. Symthera is the first biotechnology company to apply the power of network theory to drug discovery and has pioneered a novel approach to modulating the immune network. Symthera has identified peptides motifs using systems biology approaches of sequence sharing patterns within and between cancer-associated proteins which contribute to the regulation of cell cycle progression.
