DelMar to Acquire Adgero Biopharmaceuticals, Expands Late-Stage Oncology Pipeline

Combination creates a diversified biopharmaceutical company with a robust product pipeline targeting rare, unmet medical needs in oncology

Pipeline led by two late-stage, Phase 3-ready cancer therapeutics – VAL-083 for glioblastoma multiforme (GBM) and REM-001 for cutaneous metastatic breast cancer (CMBC)

Upon closing of the acquisition, DelMar intends to change its name to Kintara Therapeutics and continue trading on NASDAQ under the new symbol “KTRA”

Multiple, potential, late-stage clinical milestones expected over the next 12-18 months

SAN DIEGO & PRINCETON (June 10, 2020) – DelMar Pharmaceuticals, Inc. (Nasdaq: DMPI) (“DelMar”) and Adgero Biopharmaceuticals Holdings, Inc. (“Adgero”) today announced the companies have entered into a definitive merger agreement pursuant to which DelMar, a biopharmaceutical company focused on the development of new solid tumor cancer therapies, will acquire Adgero, a privately held biopharmaceutical company focused on the development of its late stage photodynamic therapy platform for the treatment of serious cutaneous oncology indications. In an all-equity transaction, Adgero stockholders will receive shares of DelMar common stock for shares of Adgero common stock.

Upon completion of the merger, current DelMar and Adgero stockholders will own 50.5% and 49.5% of the total voting power of the combined company, respectively, exclusive of securities to be issued in a financing to occur prior to the merger closing, as well as compensation payable in connection with the merger and the financing. Subject to stockholder approval of both companies and other closing conditions, the transaction is expected to close in the third quarter of 2020, at which time DelMar is expected to change its name to Kintara Therapeutics, Inc. and trade on Nasdaq under the new ticker symbol “KTRA.”

This combination brings together DelMar’s first-in-class, DNA-targeting chemotherapeutic with proven anti-cancer activities with Adgero’s photodynamic therapy platform. The combined company expects to benefit from complementary capabilities along with greater financial resources and flexibility to engage in a wide range of research and development activities that the companies believe will ultimately result in the creation of sustainable long-term growth.

“The acquisition of Adgero by DelMar positions the combined company for long-term corporate growth and increased shareholder value by bringing together DelMar’s oncology therapeutic candidate, VAL-083, and Adgero’s REM-001 photodynamic therapy with a lead indication in CMBC,” commented Saiid Zarrabian, President and Chief Executive Officer of DelMar. “This acquisition is the result of an extensive search for a suitable oncology therapy and provides the combined company with a diversified, late-stage oncology pipeline. During the next 12-18 months, we expect to achieve significant clinical milestones, driven by a seasoned leadership team that will bolster our oncology drug development expertise.”

Mr. Zarrabian continued, “The clinical data from Adgero’s REM-001 has demonstrated significant anti-tumor efficacy to date, with 80% complete responses reported across four studies in CMBC, and we believe it will be a valuable late-stage pipeline complement to DelMar’s VAL-083 as we prepare for the GBM AGILE registration study.”

John Liatos, interim Chief Executive Officer and Chief Financial Officer of Adgero, added, “This combination provides us with the opportunity to not only deepen our pipeline but also strengthen our oncology drug development expertise and capabilities. Furthermore, our enthusiasm to merge with DelMar was reinforced by the Global Coalition for Adaptive Research’s (GCAR) invitation to include VAL-083 in its GBM AGILE pivotal study for the treatment of newly-diagnosed and recurrent GBM. This is an important milestone with the potential to greatly reduce VAL-083’s development timeline and speaks to the potential of VAL-083 given that only a limited number of drug candidates will be invited to participate in the study. On our end, we are tremendously proud of the progress we have accomplished to date and through this combination, we look forward to creating a highly focused oncology company that can develop new therapies to help physicians and patients combat cancers where current treatment options are limited.”

Merger Process Overview and Financial Rationale

Each outstanding share of Adgero common stock will be converted into shares of DelMar common stock at an exchange ratio such that current DelMar and Adgero stockholders will own 50.5% and 49.5% of the total voting power of the combined company, respectively (the “Exchange Ratio”), upon completion of the merger and exclusive of (i) securities to be issued in a financing to occur prior to the merger closing and (ii) compensation payable in connection with the merger and the financing. Each of the 1,470,092 outstanding warrants to purchase Adgero’s common stock will be exchanged for a warrant to purchase DelMar common stock as calculated based on the Exchange Ratio, resulting in a total of 2,299,036 additional DelMar warrants outstanding. Each outstanding Adgero stock option, whether vested or unvested, that has not been exercised will be cancelled for no consideration as it is anticipated that none of the options will be in-the money at the time of the merger.

About DelMar

Located in San Diego, California, DelMar is focused on the development and commercialization of new therapies for cancer patients who have limited or no treatment options. By focusing on understanding tumor biology and mechanisms of treatment resistance, DelMar identifies biomarkers to personalize new therapies in indications where patients are failing, or are unable to tolerate, standard-of-care treatments.

DelMar’s current pipeline is based around VAL-083, a “first-in-class”, small-molecule chemotherapeutic with a novel mechanism of action that has demonstrated clinical activity against a range of cancers, including central nervous system, ovarian and other solid tumors (e.g. NSCLC, bladder cancer, head and neck) in U.S. clinical trials sponsored by the National Cancer Institute (NCI). Based on DelMar’s internal research programs and these prior NCI-sponsored clinical studies, DelMar is conducting clinical trials to support the development and commercialization of VAL-083 to solve significant unmet medical needs.

VAL-083 is being studied in two collaborator-supported, biomarker-driven Phase 2 clinical trials for MGMT-unmethylated GBM. Overcoming MGMT-mediated resistance represents a significant unmet medical need in the treatment of GBM. In addition, DelMar has announced the allowance of a separate IND for VAL-083 as a potential treatment for platinum-resistant ovarian cancer.

About Adgero

Adgero Biopharmaceuticals Holdings, Inc. is a biopharmaceutical company focused on building a pipeline by advancing its proprietary late stage photodynamic therapy (“PDT”) platform that holds promise as a localized cutaneous or visceral tumor treatment. Additionally, PDT has immune activating properties and has potential therapeutic utility in oncology as a combination therapy in conjunction with immunotherapies. It is also being investigated in the cardiovascular setting as treatment for hemodialysis access failure. Adgero’s lead product candidate, REM-001 therapy, has been previously studied in four Phase 2/3 clinical trials in patients with cutaneous metastatic breast cancer (CMBC), who had previously received chemotherapy and/or failed radiation therapy. With clinical efficacy to date of 80% complete responses of CMBC evaluable lesions and with an existing robust safety database of approximately 1,100 patients across multiple indications, Adgero is currently focused on advancing the REM-001 program to late stage pivotal testing.
