Details and patient eligibility

About

AC480IV will be administered as a monotherapy and then in combination with docetaxel in patients with locally advanced or metastatic solid tumors for whom there are no standard or curative therapies available. It is designed to evaluate the safety and pharmacokinetic parameters of AC480IV as monotherapy and also in combination with docetaxel under the conditions of the study.

Full description

A Phase I study to determine safety and tolerability of AC480IV with and without Docetaxel in subjects with solid tumors.

Inclusion criteria

Male or female age ≥18 years
Provide written informed consent
Has histological diagnosis of a primary solid tumor malignancy that meets study criteria
Has measurable disease (or evaluable if not in MTD expansion cohort) via computed tomography (CT) or magnetic resonance imaging (MRI) scans with or without non-measurable tumors (a lesion in a previously irradiated area is eligible to be considered as measurable disease as long as there is objective evidence of progression of that lesion prior to enrollment)
Less than 4 prior systemic cancer therapies (with the exception of hormonal agents), including experimental agents, prior HER-family TKI therapies, and prior docetaxel and other taxane therapy; there are no limits to the number of prior therapies for Part 1
Women of childbearing potential (WOCBP) must be using an adequate method of contraception.
WOCBP must have a negative serum or urine pregnancy test (sensitivity ≤ 25IU human chorionic gonadotropin [hCG]/L) within 72 hours prior to the start of study drug administration
Has an ECOG performance status of 0 or 1
Has a life expectancy >3 months
Has adequate organ function as determined by laboratory tests

Exclusion criteria

Patient is currently receiving or has received within the last month prior to Cycle 1 Day 1 (6 weeks for nitrosoureas, mitomycin-C, and liposomal doxorubicin) other chemotherapeutic, hormonal, or investigational anti-cancer agents with the exception of gonadal suppression agents and bisphosphonates for osteoporosis and skeletal metastases which may be continued while on study
Patient has received other chemotherapeutic, hormonal, or investigational anti cancer agents that are outside of the timeframe described above and thus would be allowed in the study, but has toxicity that is unresolved (i.e., toxicity has resolved to Grade ≤ 1 or is deemed irreversible)
Current or anticipated need for drugs that are known cytochrome P450 isozyme CYP3A4 or CYP2C8 inducers or inhibitors; only exception is oral glucocorticoids, which are a required premedication for docetaxel
Patient received previous treatment with oral AC480
Patient using herbal and dietary supplements that may interact with CYP3A4
Patient received radiation therapy or major surgery within one month of Cycle 1 Day 1
Patient has evidence of clinically unstable brain metastases (controlled and stable brain metastasis must be previously treated and asymptomatic)
Patient has uncontrolled or significant cardiovascular disease, including:
- A myocardial infarction within 6 months prior to study entry;
- Uncontrolled angina within 6 months prior to study entry;
- History of congestive heart failure (CHF) New York Heart Association (NYHA) class 3 or 4;
- LVEF that is ≤50% (or ≥ institutional lower limit of normal);
- Heart rate <50 beats per minute;
- Diagnosed or suspected congenital long QT syndrome;
- Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de Pointes [TdP]);
- Prolonged corrected interval between the Q wave and T wave (QTc) by Fridericia's correction factor (QTcF) interval on pre-entry ECG ≥450 ms (average of 3 ECG readings done in triplicate);
- Any history of second or third degree heart block;
- Uncontrolled hypertension;
- Obligate need for a cardiac pacemaker;
- Complete left bundle branch block;
- Atrial fibrillation; and
- Abnormal baseline Troponin-I.
Patient is using drugs (or has medical conditions) that are generally accepted to have a risk of causing torsades de pointes (TdP) patients who have discontinued any of these medications must have a wash-out period of at least 5 days or 5 half-lives of the drug (whichever is greater) prior to the first dose of AC480IV
Patient is in need of anticoagulation therapy except for low-dose heparin or low-dose coumadin for maintenance of patency of central venous access or prevention of deep vein thrombosis (DVT)
Women who are pregnant or breastfeeding
Male or female patients who are sexually active and unwilling to take contraceptive measures for the duration of the treatments and for 3 months following discontinuation of AC480IV
Patient with serious uncontrolled concurrent medical illness including but not limited to ongoing or active infection, and "currently active" second malignancies other than non-melanoma skin cancers
Patient with psychiatric illness or social situations that would limit compliance with treatment or adequate informed consent
Patient has pre-existing peripheral neuropathy Grade >1
Patient has prior hypersensitivity reaction or intolerance to docetaxel or other drugs formulated with polysorbate 80
