• Philadelphia, PA (April 16, 2018) – Oncoceutics, Inc. announced today that the first patient has been treated in a Phase I/II clinical trial of ONC201 in combination with ixazomib and dexamethasone in relapsed and/or refractory multiple myeloma. The trial, led by Ajai Chari, MD, Associate Professor at the Icahn School of Medicine at Mount Sinai, is entitled “A Phase I/II Study of the Addition of Ixazomib to ONC201 and Dexamethasone in Relapsed and/or Refractory Multiple Myeloma” (NCT03492138) and seeks to combine two oral medications that have shown synergy against multiple myeloma in preclinical models.  The study will enroll up to 36 adult patients and will evaluate the safety and tolerability of ONC201 in combination with ixazomib and dexamethasone in Phase I and determine the two-month disease control rate as the primary endpoint of Phase II.

    While Oncoceutics is currently focused on clinical trials of ONC201 in high-grade gliomas as its lead indication, the company continues to advance a number of clinical programs in B cell malignancies because they have shown some of the highest sensitivity against ONC201 in pre-clinical models. Oncoceutics currently has two programs in multiple myeloma: “Oral ONC201 in Relapsed/Refractory Multiple Myeloma” (NCT02863991) and the combination trial with ixazomib described above.

    Multiple myeloma is highly sensitive to proteasome inhibitors that activate the integrated stress response, the same pathway activated by ONC201 treatment through unique triggers. ONC201 synergizes with proteasome inhibitors since they converge on some of the same downstream effects as ONC201 even though they use distinct triggers in tumor cells. Based on this rationale, which is supported by published preclinical studies (Prabhu et al, Cell Cycle 2018; Tu et al, Neoplasia 2017), this clinical trial will test the combination of ONC201 with ixazomib and dexamethasone. Ixazomib, which goes by brand name NINLARO, is an oral proteasome inhibitor developed by Takeda Pharmaceutical Company. It is FDA approved in combination with lenalidomide and dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy. In addition to the U.S., NINLARO is approved in more than 50 countries.

    “We are excited to have the opportunity to test these two oral agents that have demonstrated efficacy against multiple myeloma in pre-clinical settings to provide therapies to patients with refractory/relapsed multiple myeloma that are in need of novel therapies,” said Ajai Chari, Associate Professor, Medicine, Hematology and Medical Oncology, at the Icahn School of Medicine at Mt. Sinai.


    About Oncoceutics

    Oncoceutics, Inc. is a clinical-stage drug discovery and development company with a novel class of compounds that selectively target G protein-coupled receptors for oncology. The first lead compound to result from this program is ONC201, an orally active DRD2 small molecule antagonist that is well-tolerated and effective against advanced cancers. The company recently completed a successful Phase I study in solid tumors and has begun additional Phase I/II and Phase II clinical programs in both solid and hematological malignancies. Oncoceutics and collaborative groups have received significant grants over the last two years, from institutions such as the National Cancer Institute, the U.S. Food and Drug Administration, the Pennsylvania Department of Health, and The Musella Foundation. In addition, outside interest in the company’s portfolio has resulted in several R&D alliance agreements and collaborations between Oncoceutics and leading cancer research institutions, including The University of Texas MD Anderson Cancer Center, the NIH/NCI, Harvard and the Fox Chase Cancer Center.  The company has established a robust intellectual property position, including several issued patents.

    • Thrombocytopenia has been reported with NINLARO. During treatment, monitor platelet counts at least monthly, and consider more frequent monitoring during the first three cycles. Manage thrombocytopenia with dose modifications and platelet transfusions as per standard medical guidelines. Adjust dosing as needed. Platelet nadirs occurred between Days 14-21 of each 28-day cycle and typically recovered to baseline by the start of the next cycle.
    • Gastrointestinal Toxicities, including diarrhea, constipation, nausea and vomiting, were reported with NINLARO and may occasionally require the use of antidiarrheal and antiemetic medications, and supportive care. Diarrhea resulted in the discontinuation of one or more of the three drugs in 1% of patients in the NINLARO regimen and < 1% of patients in the placebo regimen. Adjust dosing for severe symptoms.
    • Peripheral Neuropathy (predominantly sensory) was reported with NINLARO. The most commonly reported reaction was peripheral sensory neuropathy (19% and 14% in the NINLARO and placebo regimens, respectively). Peripheral motor neuropathy was not commonly reported in either regimen (< 1%). Peripheral neuropathy resulted in discontinuation of one or more of the three drugs in 1% of patients in both regimens. Monitor patients for symptoms of peripheral neuropathy and adjust dosing as needed.
    • Peripheral Edema was reported with NINLARO. Monitor for fluid retention. Investigate for underlying causes when appropriate and provide supportive care as necessary. Adjust dosing of dexamethasone per its prescribing information or NINLARO for Grade 3 or 4 symptoms.
    • Cutaneous Reactions: Rash, most commonly maculo-papular and macular rash, was reported with NINLARO. Rash resulted in discontinuation of one or more of the three drugs in < 1% of patients in both regimens. Manage rash with supportive care or with dose modification.
    • Hepatotoxicity has been reported with NINLARO. Drug-induced liver injury, hepatocellular injury, hepatic steatosis, hepatitis cholestatic and hepatotoxicity have each been reported in < 1% of patients treated with NINLARO. Events of liver impairment have been reported (6% in the NINLARO regimen and 5% in the placebo regimen). Monitor hepatic enzymes regularly during treatment and adjust dosing as needed.
    • Embryo-fetal Toxicity: NINLARO can cause fetal harm. Women should be advised of the potential risk to a fetus, to avoid becoming pregnant, and to use contraception during treatment and for an additional 90 days after the final dose of NINLARO. Women using hormonal contraceptives should also use a barrier method of contraception.



    The most common adverse reactions (≥ 20%) in the NINLARO regimen and greater than the placebo regimen, respectively, were diarrhea (42%, 36%), constipation (34%, 25%), thrombocytopenia (78%, 54%; pooled from adverse events and laboratory data), peripheral neuropathy (28%, 21%), nausea (26%, 21%), peripheral edema (25%, 18%), vomiting (22%, 11%), and back pain (21%, 16%). Serious adverse reactions reported in ≥ 2% of patients included thrombocytopenia (2%) and diarrhea (2%).



    • Hepatic Impairment: Reduce the NINLARO starting dose to 3 mg in patients with moderate or severe hepatic impairment.
    • Renal Impairment: Reduce the NINLARO starting dose to 3 mg in patients with severe renal impairment or end-stage renal disease requiring dialysis. NINLARO is not dialyzable.
    • Lactation: Advise nursing women not to breastfeed during treatment with NINLARO and for 90 days after the last dose.


    DRUG INTERACTIONS: Avoid concomitant administration of NINLARO with strong CYP3A inducers.
