Azaya Therapeutics

Status and phase: Unknown; Phase 1

Conditions: Malignant Female Reproductive System Neoplasm; Ovarian Tumor; Ovarian Epithelial Cancer Recurrent; Cancer; Ovarian Cancer

Treatments: Drug: DOXIL/CAELYX; Drug: ATI-0918

Study type: Interventional

Funder types: Industry

Identifiers

ATI0918-101

Details and patient eligibility

About

The purpose of this study is to find the answers to the following research question(s):

1. Is the study drug equivalent to the approved drug, Doxil/Caelyx, and does it act the same way in the body as the approved drug?

ATI-0918 is believed to be a generic of Doxil/Caelyx and this is what the study is trying to prove. All people who participate in this study will receive the research study medication (ATI-0918) and Doxil/Caelyx in addition to best supportive care (treatment for symptoms).

The study drug being tested in this study works the same as the FDA (government) approved drug doxorubicin HCl. ATI-0918 is a generic (the same) formulation of doxorubicin HCl being delivered (given to the patient).

Enrollment: 40 estimated patients

14. Agree to use effective contraceptive methods during the study (nonsterile patients of childbearing potential)

Exclusion criteria

1. Have New York Heart Association (NYHA) Class III or IV cardiac disease, myocardial infarction within the past 6 months prior to Day 1, unstable arrhythmia, or evidence of ischemia on electrocardiogram (ECG) or during Cardiac Stress Testing within 14 days prior to Day 1
2. Have received > 250 mg/m2 of doxorubicin or equivalent as other anthracyclines or similar compounds
3. Have received prior treatment with DOXIL/CAELYX

9. Have an active, uncontrolled bacterial, viral, fungal, or other opportunistic infections requiring systemic therapy
10. Are pregnant or nursing. NOTE: Nonsterile women of childbearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; or abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.
11. Have received treatment with radiation therapy, surgery, chemotherapy, or investigational therapy within one month prior to study entry (6 weeks for nitrosoureas or Mitomycin C).

14. Have known infection with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C
15. Have a serious nonmalignant disease (e.g., hydronephrosis, liver failure, significantly impaired hepatic function, or other conditions) that could compromise protocol objectives in the opinion of the investigator and/or the sponsor
16. Are currently receiving any other investigational agent
17. Have exhibited allergic reactions to doxorubicin or a similar structural compound
