Phase: Phase 1

Status: Completed

Sponsored by: Abbott

Official(s) and/or principal investigator(s):
Mack Mabry, MD, Study Director, Affiliation: Abbott

Summary

This is a Phase 1 open-label study evaluating the safety of ABT-263 when combined with a standard and weekly regimen of docetaxel in subjects who have solid tumors with measurable disease.

Clinical Details

Official title: A Phase 1 Safety and Pharmacokinetic Study of ABT-263 in Combination With TaxotereŽ (Docetaxel) in the Treatment of Subjects With Solid Tumors

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Assess the safety profile of navitoclax (ABT-263) when administered in combination with a standard and weekly regimen of docetaxel.

Study the pharmacokinetic interaction of navitoclax (ABT-263) and docetaxel

Determine the maximum tolerated dose (MTD) of navitoclax (ABT-263) with a standard regimen of docetaxel

Determine the MTD of both navitoclax and docetaxel with a weekly schedule.

Secondary outcome:

Evaluate safety at the defined recommended Phase 2 dose (RPTD) and schedule in combination with a standard and weekly regimen of docetaxel.

Evaluate preliminary data regarding progression free survival

Evaluate preliminary data regarding objective response rate

Evaluate preliminary data regarding overall survival

Evaluate preliminary data regarding duration of overall response

Evaluate preliminary data with Eastern Cooperative Oncology Group (ECOG) performance status

Evaluate biomarkers

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria

- Subject must be greater then or equal to 18 years of age.

- Subject must have a histologically and/or cytologically documented cancer for which

docetaxel has been determined to be an appropriate therapy, per the Investigator.

- Subject must have evaluable and/or measurable disease by Computed Tomography (CT) or

Magnetic Resonance Imaging (MRI) as defined by RECIST.

- Subjects with brain metastases must have clinically controlled neurologic symptoms,

defined as surgical excision and/or radiation therapy followed by 21 days of stable neurologic function and no evidence of CNS disease progression as determined by CT or MRI within 28 days prior to the first dose of study drug.

- Subject has an Eastern Cooperative Oncology Group (ECOG) performance score of less

then or equal to 1.

- Subject must have adequate bone marrow, renal and hepatic function per local

laboratory reference range as follows:

- Bone marrow: Absolute Neutrophil Count (ANC) greater then or equal to

1500/microliters; platelets greater then or equal to 150,000/mm^3; hemoglobin greater then or equal to 9. 0 g/dL;

- Renal function: Serum creatinine less then or equal 2. 0 mg/dL or calculated

creatinine clearance greater than or equal to 50 mL/min;

- Hepatic function and enzymes: AST and ALT less then or equal to 1. 5 x the upper

limit of normal (ULN) of institution's normal range, ALP less then or equal to 2. 5 x ULN, and bilirubin less then or equal to 1. 0 x ULN. Subjects with bone metastasis may have ALP less then or equal to 5. 0 x ULN.

- Coagulation: aPTT and PT not to exceed less than or equal to 1. 2 x ULN.

- Female subjects must be surgically sterile, postmenopausal (for at least one year),

or have negative results for a pregnancy test performed as follows:

- At Screening via a serum sample obtained within 14 days prior to initial study drug

administration, and

- Prior to dosing via a urine sample obtained on Cycle 1 Day 1, if it has been greater

then 7 days since obtaining the serum pregnancy test results.

- Female subjects not surgically sterile or postmenopausal (for at least one year) and

non-vasectomized male subjects must practice at least one of the following methods of birth control:

- total abstinence from sexual intercourse (minimum one complete menstrual cycle);

- vasectomized partner;

- hormonal contraceptives (oral, parenteral or transdermal) for at least three

months prior to study drug administration;

- Double-barrier method (including condoms, contraceptive sponge, diaphragm or

vaginal ring with spermicidal jellies or cream).

- The subject, or legal representative, must voluntarily sign and date an informed

consent, approved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB), prior to the initiation of any screening or study-specific procedures. Exclusion Criteria

- The subject has an underlying, predisposing condition of bleeding or currently

exhibits signs of bleeding. The subject has a recent history of thrombocytopenia associated with bleeding within 1 year prior to first dose of study drug.

- The subject is currently receiving or requires anticoagulation therapy or any drugs

or herbal supplements that affect platelet function, with the exception of low-dose anticoagulation medications (i. e., Heparin) that are used to maintain the patency of a central intravenous catheter.

- A female subject is pregnant or breast-feeding.

- The subject has active peptic ulcer disease or other potentially hemorrhagic

esophagitis/gastritis.

- The subject has active immune thrombocytopenic purpura (ITP), autoimmune hemolytic

anemia (AIHA), or a history of being refractory to platelet transfusions (within 1 year prior to the first dose of study drug).

- The subject has received any anti-cancer therapy including chemotherapy,

immunotherapy, radiotherapy, hormonal therapy (with the exception of hormones for hypothyroidism, estrogen replacement therapy [ERT], anti estrogen analogs, agonists required to suppress serum testosterone levels [e. g., LHRH, GnRH, etc.] for subjects with prostate cancer if on a stable dose for at least 21 days prior to the first dose of study drug), or any investigational therapy with 14 days prior to the first dose of study drug, or has not recovered to less than a grade 2 clinically significant adverse effect(s)/toxicity(s) of the previous therapy.

- The subject has received an antibody therapy or other biologic (with the exception of

colony stimulating factors [G-CSF, GM-CSF] or erythropoietin) within 28 days prior to the first dose of study drug.

- The subject has consumed grapefruit or grapefruit products within 3 days prior to the

first dose of study drug.

- The subject has received steroid therapy for anti-neoplastic intent within 7 days

prior to the first dose of study drug with the exception of inhaled steroids for asthma, topical steroids, replacement/stress corticosteroids, or corticosteroids taken as premedication for this study.

- The subject has received aspirin or known CYP3A inhibitor (e. g., ketoconazole) within

7 days prior to the first dose of study drug.

- The subject has undergone an allogeneic stem cell transplant.

- The subject has received radio-immunotherapy within 6 months prior to the first dose

of study drug.

- The subject has a history of hypersensitivity to docetaxel or other polysorbate 80

drugs.

- The subject has tested positive for human immunodeficiency virus, HIV (due to

potential drug-drug interactions between anti-retroviral medications and navitoclax (ABT-263), as well as anticipated navitoclax (ABT-263) mechanism based lymphopenia that may potentially increase the risk of opportunistic infections and potential drug-drug interactions with certain anti infective agents).

- The subject has a significant history of cardiovascular (e. g., MI, thrombotic or

thromboembolic event in the last 6 months), renal, neurologic, psychiatric, endocrinologic, metabolic, immunologic, or hepatic disease that in the opinion of the investigator would adversely affect his/her participating in this study. Questions regarding inclusion of individual subjects should be directed to the Abbott Medical Monitor or designee.

- The subject exhibits evidence of other clinically significant uncontrolled

condition(s) including, but not limited to:

- active systemic fungal infection;

- A diagnosis of fever and neutropenia within 1 week prior to study drug

administration.
