2X-121 is a PARP inhibitor. This clinical trial will enroll metastatic Breast Cancer patients, who have relapsed on two or more different prior therapies. The 2X-121 DRP is a novel biomarker based on 414 genes predictive of response to 2X121. In a study presented at ASCO, the 2X-121 DRP correctly identified responders and non-responders to treatment irrespective of BRCA mutation status.

Patients will receive oral treatment with 600 mg 2X-121, in a 21-day cycle. The primary endpoint of this study is clinical benefit rate defined as complete response, partial response, or stable disease at greater than 24 weeks post-treatment. Secondary endpoints include progression free survival, duration of response (from first response to progression), and overall survival.

“This Phase 2 study will enable us to rapidly evaluate the efficacy of our PARP inhibitor in metastatic breast cancer patients, using the 2X-121 DRP® using over 400 genes to select likely responders,” said Peter Buhl Jensen CEO of Oncology Venture. “We are very encouraged by the DRP data based on the available biopsies from 13 patients from the foregoing phase 1 study. In this small population the DRP could convincingly pick responding patients. Use of PARP inhibitors is a revolution in the right patients and we believe that our DRP can find these patients”, Peter Buhl Jensen further commented.

2X-121 Phase 2 study in metastatic Breast Cancer (mBC) 2X-121 is an investigational, orally-available small molecule targeted inhibitor of Poly ADP ribose polymerase (PARP), a key enzyme involved in DNA damage repair in cancer cells. The drug candidate has a novel dual-inhibitory action against both PARP 1/2 and Tankyrase 1/2. The molecule is also active in P-glycoprotein expressing cells, suggesting it may overcome PARP inhibitor resistance. Patients will receive oral treatment with 600 mg 2X121, as a single agent, in a 21-day cycle. The primary endpoint of this study is clinical benefit rate defined as complete response, partial response, or stable disease at greater than 24 weeks post-treatment using the RECIST criteria. Secondary endpoints include progression free survival, duration of response (from first response to progression), and overall survival. Separate, targeted Phase 2 studies of 2X-121 are planned using the validated DRP® biomarker in recurrent ovarian cancer, castration resistant prostate cancer, and pancreatic cancer to identify patients likely to respond to and benefit from treatment with the drug.

About the Drug Response Predictor - DRP® Companion Diagnostic Oncology Venture uses the Medical Prognosis Institute (MPI) multi gene DRP® to select those patients who by the genetic signature of their cancer are found to have a high likelihood of responding to the drug. The goal is developing the drug for the right patients, and by screening patients before treatment the response rate can be significantly increased. The DRP® method builds on the comparison of sensitive vs. resistant human cancer cell lines, including genomic information from cell lines combined with clinical tumor biology and clinical correlates in a systems biology network. DRP® is based on messenger RNA from the patient’s biopsies. The DRP® platform, i.e. the DRP® and the PRP™ tools, can be used in all cancer types and is patented for more than 70 anti-cancer drugs in the US. The PRP® is used by MPI for Personalized Medicine. The DRP® is used by Oncology Venture for drug development. DRP® is a registered trademark of Medical Prognosis Institute A/S.

About Oncology Venture Sweden AB Oncology Venture Sweden AB is engaged in the research and development of anti-cancer drugs via its wholly owned Danish subsidiary Oncology Venture ApS. Oncology Venture has a license to use Drug Response Prediction – DRP® – in order to significantly increase the probability of success in clinical trials. DRP® has proven its ability to provide a statistically significant prediction of the clinical outcome from drug treatment in cancer patients in 29 out of 37 clinical studies that were examined. The Company uses a model that alters the odds in comparison with traditional pharmaceutical development. Instead of treating all patients with a particular type of cancer, patients’ tumors genes are first screened, and only the patients most likely to respond to the treatment will be treated. Via a more well-defined patient group, risks and costs are reduced while the development process becomes more efficient. ? The current product portfolio: LiPlaCis® for Breast Cancer in collaboration with Cadila Pharmaceuticals, Irofulven developed from a fungus for Prostate Cancer, and APO010: an immuno-oncology product for Multiple Myeloma. Oncology Venture has spun out two companies as Special Purpose Vehicles: 2X Oncology Inc. is a US based company focusing on precision medicine, currently with a pipeline of three promising phase 2 product candidates. OV-SPV 2 is a Danish company that will test and potentially develop an oral phase 2 Tyrosine Kinase inhibitor.

About Oncology Venture US Inc. (previously named 2X Oncology Inc.) Oncology Venture US Inc. (OV US) is a clinical stage precision medicine company developing targeted therapeutics addressing significant unmet needs in hard-to-treat cancers. Our pipeline leverages a proprietary Drug Response Predictor (DRP®) technology generating drug specific companion diagnostics to identify patients who are most likely to respond and benefit from treatment. DRP® also identifies likely non-responder patients, providing a precision medicine approach for the treatment of patients who can benefit from our therapies. The OV US pipeline of product candidates, including a PARPi, are focused on the treatment of breast, ovarian, prostate and pancreatic cancers and primary and secondary brain tumors. These programs have demonstrated clinical efficacy and safety and are positioned to enter focused Phase 2 studies with study data and potential accelerated approval filings expected in 2H 2018. A Cambridge, MA based spin-out from Oncology Venture ApS, OV US works in close collaboration with Oncology Venture and leverages a Danish registry of over 1,200 cancer patients which only counts for the breast cancer patients for select clinical studies. 2X Oncology Inc. has recently changed name to Oncology Venture US Inc. to taking into account that the DRP® technology is aimed to benefit all genders.
