Clinical Study of Oral IGF-1R Inhibitor in Subjects With Advanced Refractory Solid Tumors
Clinical study of oral IGF-1R inhibitor PL225B in subjects with advanced refractory solid tumors. The primary objective is to determine the maximum tolerated dose and dose limiting toxicity (ies) of oral IGF-1R inhibitor PL225B in subjects with advanced refractory solid tumors.
Inclusion Criteria
- Subjects having histologically and/or cytologically confirmed non-haematological malignancy that is metastatic or unresectable and for which standard curative or palliative treatment does not exist or is no longer effective
- Subjects should have measurable or evaluable disease
- Subjects of either sex, of all races and ethnic groups, and ≥18 years of age
- ECOG (Eastern Cooperative Oncology Group) performance status 0-1
- Subjects with life expectancy of at least 4 months
- Subjects with fasting plasma glucose ≤ 125 mg/dL and HbA1c < 6.5 % at screening Subjects with fasting plasma glucose ≤150 mg/dL and HbA1c ≤ 7.0 % at screening for the Diabetes Expansion Cohort.
- For the Diabetes Expansion Cohort - Subjects with known history of type 2 diabetes mellitus that are well-controlled on a stable dose of oral anti-diabetic agents such as metformin and/or sulfonylureas for 4 weeks prior to screening.
- Subjects must have normal organ and marrow function as defined below:
- Absolute neutrophil count ≥ 1500/cmm
- Platelets ≥ 100,000/cmm
- Total bilirubinwithin normal limits of the institution
- AST/ALT ≤ 2.5 X institutional upper limit of normal (ULN) or ≤ 5 X institutional upper limit of normal (ULN) in the presence of liver metastases
- Creatinine ≤ 1.5 X institutional upper limit of normal (ULN)
- Subjects willing for repeat oral dosing and follow-up, including pharmacokinetic sampling
- Women of childbearing potential and men willing to agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, during the duration of study participation and for at least 4 weeks after withdrawal from the study, unless they are surgically sterilised
- Ability to understand and the willingness to provide a written informed consent document
Exclusion Criteria
- Subjects who have received any prior chemotherapy, radiotherapy, biologic/targeted anti-cancer therapy or surgery within 4 weeks (6 weeks for monoclonal antibodies, radioactive monoclonal antibodies or any radio- or toxin- immunoconjugates) before the first study drug administration and have not recovered (to AEs < Grade 2) from the toxic effects from any prior therapy
- Subjects having received any other investigational agents within 4 weeks prior to the first study drug administration and have not recovered completely (to AEs < Grade 2) from the side effects of the earlier investigational agent
- Subjects with documented history of diabetes mellitus except for the Diabetes Expansion Cohort
- For the Diabetes Expansion Cohort - Subjects who have type 1 diabetes mellitus, maturity onset diabetes of the young, hyperglycemia due to reasons other than type 2 diabetes mellitus.
- For the Diabetes Expansion Cohort - Subjects who currently require insulin, thiazolidinediones, dual proliferator-activated receptors (PPAR) agonists, glucagon-like peptide (GLP-1) analogues, dipeptidyl peptidase (DPP-IV) inhibitors or have received the same in the 4 weeks prior to screening.
- Subjects with known complications of diabetes like diabetic nephropathy or diabetic retinopathy
- Subjects with known brain metastases
- Subjects with gastrointestinal abnormalities including inability to take oral medication, malabsorption or other conditions like chronic inflammatory bowel disease that may affect absorption.
- Subjects with a history of myocardial infarction or uncontrolled cardiac dysfunction during the previous 6 months
- Subjects with baseline QTc interval >470 msec at screening
- Subjects on warfarin. Prophylactic anticoagulation with low molecular weight heparin is allowed
- Subjects with history of anaphylaxis or angioedema, bronchial asthma, peptic ulcer and clinically significant food or drug allergy
- Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Women who are pregnant or nursing
- Subjects with known seropositivity to human immunodeficiency virus (HIV), positive for Hepatitis B, positive for Hepatitis C (antigen positive), or known hepatic cirrhosis

An open label multicentre Phase 1 study of oral IGF-1R inhibitor PL225B in subjects with
advanced refractory solid tumors. This is a dose-finding trial using the modified
Accelerated Titration Design with 3 new subjects per cohort and 100% dose increments in
the accelerated phase followed by standard phase with 40% dose increments.Subjects will
receive study drug on a daily basis for twenty-one (21) days according to the dose and
schedule specified for a particular cohort of therapy. Toxicity profile of the drug will
be assessed during Cycle 1 of subject treatment in each cohort for determination of
Maximum Tolerated Dose (MTD) according to the schedule given below.
