    Avacta: Unlocking the Therapeutic Potential of Proven Oncology Agents Through Tumor-Selective pre|CISION® Delivery pre|CISION® Pipeline: 3 Assets Team INACTIVE Toxic payload A tumor-selective delivery 1st in clinical trials Experienced platform that expands the 2nd set to enter clinic Leadership tea

  3. Slide 3: pre|CISION Unlocks Potential of High Potency Oncology Drugs

    pre|CISION: Unlocks the Therapeutic Potential of High Potency Oncology Drugs Previously Constrained by Systemic Toxicity Many current oncology therapies have By concentrating in the tumor and sparing severe toxicities at the effective dose, thus normal tissues, pre|CISION aims to a limited therapeut

  4. Slide 4: The pre|CISION Mechanism of Action

    The pre|CISION® Mechanism Tumor cell intracellular space Released of Action payload Released (free) payload peptide enters FAP- tumor or FAP+ CAF cells Tumor: Stroma Interface Peptide drug conjugate cannot enter cells The pre|CISION peptide binds in the active site of FAP and is specifically cleaved
