A Phase I Study Of Pazopanib With Either Erlotinib Or Pemetrexed In Patients With Advanced Solid Tumors

Completed · Phase 1

Conditions studied: Lung Cancer, Non-Small Cell

In brief

This is an open-label, two-arm, Phase I, dose escalation study to evaluate the safety and tolerability and to determine the maximum tolerated dose (MTD) of pazopanib in combination with erlotinib (Arm A) or pazopanib in combination with pemetrexed (Arm B) in patients with advanced solid tumors. Patients will be enrolled in cohorts of 3 (in each arm) to receive escalating doses of pazopanib and erlotinib or pazopanib and pemetrexed. Dose escalation schemas for each study arm are described in the protocol. For each arm, the MTD regimen will be defined as the highest dose combination of the agents where no more than one out of six patients experiences a dose-limiting toxicity. Six to twelve additional patients in each arm will be studied with the MTD regimen to evaluate toxicity and pharmacokinetics. In arm A (erlotinib), a run-in phase with each drug separately will allow an evaluation of pharmacokinetics with each drug separately and also for the two drugs in combination. This will allow an assessment of potential drug-drug interactions. Pharmacokinetic endpoints will be AUC, Cmax, tmax and t1/2 of pazopanib, erlotinib, and pemetrexed, as well as pemetrexed clearance before and after administration of pazopanib in the extension cohort of Arm B. Antitumor activity will be assessed using RECIST criteria.

You may qualify if…

• A subject will be considered eligible for inclusion in this study only if all of the following criteria are met:
• Subjects must provide written informed consent prior to performance of study specific procedures or assessments, and must be willing to comply with treatment and follow up.
• ·Procedures conducted as a part of routine clinical management of the subject (e.g., blood count, imaging study) and obtained prior to signed informed consent may be utilized for Screening or Baseline purposes provided these tests are obtained as specified in the protocol.
• Histologically- or cytologically-confirmed diagnosis of advanced solid tumor that has failed standard therapy or for which there is no standard therapy. Subjects for whom erlotinib or pemetrexed are standard therapy may also be entered.
• Age ≥18 years.
• ECOG Performance status must be ≤1.
• Adequate organ system function as defined in Table 9. System (Laboratory Values)
• Hematologic:
• Absolute neutrophil count (ANC) ((≥1.5 X 10\^9/L)) Hemoglobin (≥10 g/dL) Platelets (≥ 100 X 10\^9/L) Prothrombin time (PT) or international normalized ration (INR) (≤ 1.2 X upper limit of normal (ULN)) Activated partial thromboplastin time (APTT) (≤ 1.2 X ULN)
• Hepatic:
• Total bilirubin (≤1.5 X ULN) AST and ALT (≤ 2.5 X ULN)
• Renal:
• Serum creatinine (≤ 1.5 mg/dL) Or, if greater than 1.5 mg/dL Calculated creatinine clearance (≤ 50 mL/min) Urine Protein to Creatinine Ratio (UPC)2 < 1
• Subjects may not have had a transfusion within 7 days of screening assessment.
• If UPC ≥ 1, then a 24-hour urine protein must be assessed and 24-hour urine protein must be <1 g protein to be eligible.
• Measurable disease on CT scan.
• A female subject is eligible to enter and participate in the study if she is of: • Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), including any woman who has had:• A hysterectomy
• A bilateral oophorectomy (ovariectomy)
• A bilateral tubal ligation
• Is post-menopausal:
• Subjects not using hormone replacement therapy (HRT) must have experienced total cessation of menses for ≥1 year and be greater than 45 years in age, OR, in questionable cases, have a follicle stimulating hormone (FSH) value >40mIU/mL and an estradiol value <40pg/mL (<140pmol/L).
• Subjects must discontinue HRT prior to study enrollment due to the potential for inhibition of CYP enzymes that metabolize estrogens and progestins (see Section 8). For most forms of HRT, at least 2 4 weeks must elapse between the cessation of HRT and determination of menopausal status; length of this interval depends on the type and dosage of HRT. If a female subject is determined not to be post-menopausal, they must use adequate contraception, as defined immediately below.
• OR of Childbearing potential, including any female who has had a negative serum pregnancy test within 2 weeks prior to the first dose of study treatment, preferably as close to the first dose as possible, and agrees to use adequate contraception. GSK acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of the physician, are as follow:
• An intrauterine device with a documented failure rate of less than 1% per year.
• Vasectomized partner who is sterile prior to the female subject's entry and is the sole sexual partner for that female.

You may not qualify if…

Screening with CNS imaging studies (computed tomography [CT] or magnetic resonance imaging [MRI]) is required for all subjects.
