Discovery Platform

Revolutionizing the future of cancer therapy

Three proprietary integrated discovery technologies fueling DDR pipeline growth

Aprea’s drug discovery and development processes integrate three unique platforms: Repli-Biom, ATRIZE and SCET.

These integrated technologies provide us with the opportunity to enrich our pipeline with novel targets in synthetic lethality and cancer treatment.

In addition, by utilizing our integrated technologies we have identified cancer-associated gene alterations that can lead to increased sensitivity to Aprea’s DDR inhibitors and may provide future opportunities for improved efficacy and tolerability in cancer treatment.


Repli-Biom identifies proteins that cancer cells use to resist the effects of drug treatment. This integrated proteomic, genomic and machine learning approach identifies response factors that both participate in the molecular response to drug treatment and are highly mutated in cancers.

Absence of these resistance factors predict sensitivity to drug treatment, thus potentially promoting durable drug responses. In addition, this approach is being used to identify novel combination therapy approaches and new drug targets to advance Aprea’s drug development programs.


ATRIZE is an innovative, high-throughput system to detect disruption of DNA synthesis and DDR activation, and thus is ideal for screening DDR inhibitors. ATRIZE may significantly reduce the time required to discover active drug candidates and optimize their design for precision cancer therapy.

SCET (Small Cyclic Enzyme Targeting)

SCET is a medicinal chemistry cyclization approach to generate highly potent and selective enzyme inhibitors. The SCET approach enables the design and synthesis of novel conformationally-constrained drug candidates with potentially higher affinity and specificity for the target enzyme. By utilizing this approach, we have developed highly potent and specific anticancer drug candidates with decreased off-target activities.
