Phase I Study of CA-18C3 in Subjects with Advanced Hematologic Malignancies
The goal of this clinical research study is to find the highest tolerable dose of CA-18C3 that can be given to patients with advanced blood cancers. Researchers also want to learn how much and for how long the study drug stays in your body after it has been given to you. The safety of this drug will also be studied.
Disease Group: Leukemia
Treatment Agent: CA-18C3
Treatment Location: Only at MD Anderson
Sponsor: XBiotech USA, Inc.
1. To determine the toxicities, including the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) of CA-18C3 when administered intravenously at up to 7.5 mg/kg every two weeks in subjects with hematologic malignancies. Toxicities occurring in the first two cycles (28 days) will be used to determine DLT. 2. To determine the pharmacokinetics (PK) of CA-18C3 following study drug administration. 3. To observe the anti-tumor effects of CA-18C3, if any occur.
IRB Review and Approval Date: 04/21/2011
Recruitment Status: Not Accepting
Projected Accrual: N/A
1) Male or female subjects age >/= 18 years of age
2) Subject must have a relapsed/refractory leukemia for which no standard therapies are anticipated to result in a durable remission. Subjects with previously treated high-risk myelodysplasia (MDS) (Intermediate 2 or high-risk by IPSS) and chronic myelomonocytic leukemia-2 (CMML-2 by WHO classification) are also candidates for this protocol. Relapsed/refractory leukemias include acute non-lymphocytic leukemia (AML) by WHO classification, acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), or chronic myelogenous leukemia (CML) in blast crisis. Subjects with myelofibrosis are also eligible. Untreated patients with above diagnoses considered unfit for standard therapy will also be eligible. All diagnostic criteria and definitions are as per the WHO and IPSS classification systems.
3) Eastern Cooperative Oncology Group (ECOG) performance status of 0-3.
4) Women of child bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must use acceptable contraceptive methods (abstinence, intrauterine device [IUD], oral contraceptive or double barrier device), and must have a negative urine pregnancy test within 2 weeks prior to beginning treatment on this trial. Nursing subjects are excluded. Sexually active men must also use acceptable contraceptive methods for the duration of time on study. Pregnant and nursing subjects are excluded because the effects of CA-18C3 on a fetus or nursing child are unknown.
5) In the absence of rapidly progressing disease, the interval from prior treatment to time of study drug administration should be at least 2 weeks for cytotoxic agents, or at least 5 half-lives for non-cytotoxic agents. If the subject is on hydroxyurea to control peripheral blood leukemic cell counts, the subject must be off hydroxyurea for at least 48 hours before initiation of treatment on this protocol. Persistent clinically significant toxicities from prior chemotherapy must not be greater than grade 1.
6) Subjects must have the following clinical laboratory values (unless out of range values are considered to be the result of leukemic organ involvement): 1)Serum creatinine </= 2.0 mg/dl. 2) Total bilirubin </= 1.5x the upper limit of normal unless considered due to Gilbert’s syndrome. 3) Alanine aminotransferase (ALT), or aspartate aminotransferase (AST) </= 3x the upper limit of normal unless considered due to organ leukemic involvement.
7) Signed and dated institutional review board (IRB)-approved informed consent before any protocol-specific screening procedures are performed.
1) Uncontrolled intercurrent illness including, but not limited to
uncontrolled infection, symptomatic congestive heart failure, cardiac
arrhythmia, or psychiatric illness/social situations that would limit
compliance with study requirements.
2) Active heart disease including myocardial infarction within previous 3 months, symptomatic coronary artery disease, arrhythmias not controlled by medication, or uncontrolled congestive heart failure.
3) Subjects receiving any other standard or investigational treatment for their hematologic malignancy.
4) Subjects who at the time of evaluation for participation in the study have evidence of active leukemic involvement in the brain or spinal cord (CNS).
5) Dementia or altered mental status that would prohibit the understanding or rendering of informed consent
6) Subjects immunocompromised due to a process unrelated to leukemic disease or treatment, including subjects known to be infected with human immunodeficiency virus (HIV)
7) Concomitant treatment with any other therapeutic antibody, or treatment with any biologic agent that blocks the IL-1 or TNFa signaling pathway.
8) History of latent or active Tuberculosis.
