A Multicenter, Open-Label Study of the Efficacy, Safety, and Pharmacokinetics of Intravenously Infused Berubicin in Adult Patients With Recurrent Glioblastoma Multiforme (WHO Grade IV) After Failure of Standard First Line Therapy

WPD-201

This is a multicenter, open-label, Phase 1b/2 efficacy and safety study of Berubicin utilizing a Simon's 2-stage design to confirm the efficacy (or futility) of a single arm of Berubicin treatment, administered at the recommended Phase 2 dose (RP2D) identified in Phase 1 studies (7.5 mg/m2 Berubicin HCl), on the endpoint of ORR in up to approximately 61 patients. A central reader will determine the radiologic responses for each patient according to m RANO criteria. The responder criteria for this Simon's design will be based on objective response criteria defined as individual patients achieving CR or PR per m-RANO criteria within 6 months from baseline.

Patients will be eligible for the study if they meet all of the following inclusion criteria and none of the exclusion criteria. Inclusion criteria 1. Written informed consent prior to any study-related procedure, and willing and able to comply with the protocol and aware of the investigational nature of this study. 2. At least 18 years of age. 3. A diagnosis of GBM (WHO Grade IV) confirmed by: 1. Archived paraffin-embedded tissue (approximately 10 unstained slides or a tumor block) from initial resection for local review of tumor diagnosis OR 2. A tumor tissue form indicating diagnosis from initial resection of glioblastoma completed and signed by a pathologist and/OR 3. Tumor tissue from re-resection, managed as above (a OR b) 4. Measurable disease is required with documented unequivocal evidence of tumor recurrence or progression following prior therapy, confirmed by the following: 1. Recurrent GBM as documented by the principal investigator (PI). In case of recent interim debulking surgery, the histopathological verification of the resected tissue as recurrent tumor automatically qualifies the patient as eligible for the trial. 2. KPS reduction of 10 units while on stable or increasing doses of corticosteroids as documented by the PI 3. Subject MRI meets at least two of the following three criteria as determined by central review: 1. Presence of measurable disease: the lesion is ≥10 mm in both maximum perpendicular diameters 2. Evidence of unequivocal tumor recurrence or progression following prior therapy as determined by a 10% increase in the sum of the products of perpendicular diameters of the contrast-enhancing lesions 3. Substantial increase in the perilesional oedema as shown in T2/FLAIR images. 5. All contrast enhancing disease is located supratentorially 6. O\[6\] methylguanine-DNA methyltransferase (MGMT) methylation status must be available, or able to be determined from existing tumor tissue; results of routinely used methods for MGMT methylation testing (e.g., methylation-specific polymerase chain reaction \[MSPCR\] or quantitative polymerase chain reaction \[PCR\]) are acceptable. 7. No more than 1 prior line of treatment (e.g., surgery followed by radiation with concomitant chemotherapy, followed by adjuvant chemotherapy is considered as 1 line of treatment). A second debulking surgery during the first line treatment is acceptable. 8. Recovery from toxicity/side effects of all prior therapy to Grade 1 or less, subject to the investigator's discretion, except for alopecia; the following time intervals from previous treatments are required to be eligible: 1. 12 weeks from the completion of radiation (to reduce risk of pseudoprogression), unless progression is confirmed by biopsy 2. 4 weeks from the end of any previous chemotherapy or 6 weeks after the end of treatment with nitrosoureas 3. 4 weeks from any major surgery (maximal debulking surgery, either gross total resection or partial resection) or significant traumatic injury, and any surgery incisions or wounds must be completely healed 9. A stable or decreasing dose of corticosteroids (or none) for brain edema for at least 5 days prior to baseline MRI and enrollment in the study as confirmed by the PI. 10. Immunosuppressive therapies allowed include the use of topical, inhalational, ophthalmic, or intra-articular glucocorticoids, or the use of physiologic replacement doses of glucocorticoids. 11. Eligible for chemotherapy based on adequate bone marrow function and organ function within 2 weeks of study treatment as defined by the following laboratory guidelines, subject to the investigator's discretion: 1. Hematopoietic function: total white blood cell (WBC) count ≥3000/mm³, absolute neutrophil count (ANC) ≥1500/mm³, platelet count ≥75,000/mm³, hemoglobin ≥10 g/dL 2. Hepatic function: bilirubin ≤1.5 × the upper limit of normal (ULN) (excluding Gilberts Syndrome, for which bilirubin must be ≤4 × ULN); aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \<3 × ULN, and alkaline phosphatase ≤2.5 × ULN 3. Renal function: serum creatinine ≤1.5 × ULN or for patients with creatinine levels above the ULN, or estimated creatinine clearance of ≥60 mL/min/1.73 m2, calculated using the Cockcroft Gault formula 4. Activated partial thromboplastin time (aPTT) ≤1.5 × ULN. 12. Women of childbearing potential must agree to practice a highly effective method of contraception beginning at least 28 days before the start of treatment until at least 6 months after the last dose of study drug. Male study patients and their female sexual partners of childbearing potential must agree to practice a highly effective method of contraception starting from the time of informed consent until at least 3,5 months (no less than 104 days) after the last dose of study drug. 1. A woman of childbearing potential is defined as a woman who is not permanently sterilized or postmenopausal. Postmenopausal is defined as 12 months with no menses without an alternative medical cause. 2. Women of childbearing potential must have a negative serum or urine pregnancy test. 3. A highly effective method of birth control is defined as one which results in a low failure rate (i.e., less than 1% per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence, or vasectomized partner. For patients using a hormonal contraceptive method, information regarding all medications being administered to the patient and their potential effect on the contraceptive should be addressed. 13. Patients with prior malignancies must be disease-free for ≥5 years. However, curatively treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix, breast, or bladder; or prostate cancer curatively treated at the time of screening is allowed. Exclusion Criteria 1. Unable or not willing to comply with the protocol regulations. 2. Any additional concurrent radiation therapy or chemotherapy (including but not limited to temozolomide \[TMZ\]) for recurrent or progressive GBM after a first line treatment. 3. Prior treatment with bevacizumab. 4. The presence of IDH mutation prior to enrollment 5. Screening MRI showing a mass effect defined as significant compression of the ventricular system and/or a midline shift (≥10 mm) as determined by central MRI review. 6. Any condition (medical, social, psychological) that would prevent adequate information and follow-up, including but not limited to clinically relevant psychiatric disorders, legal incapacity, dementia, or altered mental status. 7. Presence of poorly controlled seizures, defined as occurring despite standard of care (SOC) or requiring hospitalization. 8. Widespread or focal leptomeningeal disease measuring ≥10mm by ≥10mm. 9.

Congestive heart failure with New York Heart Association (NYHA) classification of 3 or 4 4. Patients with baseline QT/QTc interval \>480 msec, a history of additional risk factors for torsades de pointes (TdP) (e.g., heart failure, hypokalemia, family history of long QT syndrome) and using concomitant medications that significantly prolong the QT/QTc interval 5. History of myocardial infarction within 12 months of enrollment. 11. Uncontrolled hypertension (systolic blood pressure \[BP\] \>150 mmHg and/or diastolic BP \>100 mmHg). 12. Known to be positive for hepatitis B virus surface antigen (HBsAg), hepatitis C virus (HCV), human immunodeficiency virus (HIV), coronavirus disease-2019 (COVID-19) or any other acute viral, bacterial, or fungal infection (testing not required unless symptomatic or suspected disease). 13.
