NOXXON Pharma N.V. announced publication of the abstract of its poster presentation at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting which will take place in Chicago, Illinois, US, from June 3 to June 7, 2022. The poster presentation entitled “Radiotherapy and olaptesed pegol (NOX-A12) in partially resected or biopsy-only MGMT-unmethylated glioblastoma: Interim data from the German multicenter phase 1/2 GLORIA trial” will be presented by Dr. Frank A. Giordano and will exhibit the top-line results of the Phase 1/2 GLORIA trial in brain cancer (glioblastoma). Specifically, the abstract highlights that: 40% of patients achieved partial response (PR defined as tumor size reduction over 50%), a considerable increase over the 22% previously disclosed and as reported in March 2022.

In 3 out of 10 patients, one or more non-target lesions (smaller secondary lesions) completely disappeared. The combination of radiotherapy and NOX-A12 was safe and well-tolerated, with no dose limiting toxicities and no treatment-related deaths. Only 4% of the adverse events of Grade 2 or more were deemed solely NOX-A12-related.

NOXXON's oncology-focused pipeline acts on the tumor microenvironment (TME) and the cancer immunity cycle by breaking the tumor protection barrier and blocking tumor repair. By neutralizing chemokines in the TME, NOXXON's approach works in combination with other forms of treatment to weaken tumor defenses against the immune system and enable greater therapeutic impact. NOXXON's lead program NOX-A12 has delivered final top-line data from a Keytruda® combination trial in metastatic colorectal and pancreatic cancer patients published at the ESMO conference in September 2020 and in July 2021 the company announced its Phase 2 study, OPTIMUS, to further evaluate safety and efficacy of NOX-A12 in combination with Merck's Keytruda® and two different chemotherapy regimens as second-line therapy in patients with metastatic pancreatic cancer.

NOXXON is also studying NOX-A12 in brain cancer in combination with radiotherapy which has been granted orphan drug status in the US and EU for the treatment of certain brain cancers. GLORIA, a trial of NOX-A12 in combination with radiotherapy in newly diagnosed brain cancer patients who will not benefit clinically from standard chemotherapy has delivered top-line data from all three dose-escalation cohorts showing consistent tumor reductions and objective tumor responses.
