ZNTL

We are a clinical-stage biopharmaceutical company focused on discovering and developing small molecule therapeutics targeting fundamental biological pathways of cancers. We use our highly efficient drug discovery engine, which we refer to as our Integrated Discovery Engine, to identify targets and develop small molecule new chemical entities, or NCEs, with properties that we believe could result in potentially differentiated product profiles.

Our discovery engine combines our extensive experience and capabilities across cancer biology and medicinal chemistry. We believe our product candidates are differentiated from current programs targeting similar pathways and, if approved, have the potential to significantly impact clinical outcomes of patients with cancer.

We are developing a broad pipeline of product candidates with an initial focus on validated oncology targets with the potential to address large patient populations. Our lead product candidate, ZN-c5, is an oral selective estrogen receptor degrader, or SERD, currently in a Phase 1/2 clinical trial for the treatment of advanced estrogen receptor-positive, human epidermal growth factor receptor 2-negative, or ER+/HER2-, advanced or metastatic breast cancer. We have designed ZN-c5 to have high potency and selectivity as well as favorable tolerability and pharmacokinetic, or PK, properties. We expect to report top-line data from the Phase 1, monotherapy dose escalation portion of this Phase 1/2 trial in the second half of 2020.

Our other product candidates include ZN-c3, an inhibitor of WEE1, a protein tyrosine kinase, currently in a Phase 1/2 clinical trial for the treatment of advanced solid tumors; ZN-d5, a selective inhibitor of B-cell lymphoma 2, or BCL-2, initially in development for the treatment of hematological malignancies, and ZN-e4, an irreversible inhibitor of mutant epidermal growth factor receptor, or EGFR, currently in a Phase 1/2 clinical trial for the treatment of advanced non-small cell lung cancer, or NSCLC.

We expect to report top-line data from the Phase 1 portion of the ongoing trials of each of ZN-c3 and ZN-e4 in 2021, respectively, and to submit an investigational new drug application, or IND, to the U.S. Food and Drug Administration, or FDA, for ZN-d5 in the first half of 2020 and initiate a Phase 1 clinical trial of ZN-d5 in patients with acute myeloid leukemia, or AML, or B-cell lymphoma in the second half of 2020. We currently own worldwide development and commercialization rights to each of our product candidates, other than in select Asian countries (including China) for ZN-e4 for which we have out-licensed these rights.
