Brief summary
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.
Detailed description
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.
Interventions
* Patients 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. * This 21 day administration will define a treatment cycle. * Patients may receive consecutive treatment cycles until evidence of disease progression, intolerance of therapy, or withdrawal from the protocol as specified.

Eligibility
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: 1. Absolute neutrophil count ≥ 1500/cmm 2. Platelets ≥ 100,000/cmm 3. Total bilirubinwithin normal limits of the institution 4.

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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximum tolerated dose | End of Cycle 1 (i.e. 21 Days) | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of subject with adverse events | Until disease progression or unacceptable toxicity (expected to be 4-6 months) | The toxic effects of the drug would be assessed from adverse events, vital signs and by clinically significant changes in the laboratory evaluations. |
| Pharmacokinetic profile(Cmax,Tmax and AUC) | Until disease progression or unacceptable toxicity (expected to be 4-6 months) | The following PK parameters will be calculated: Cmax (peak plasma concentration), Tmax (time to peak plasma concentration), AUC0-t (area under the plasma concentration curve from time zero to time of last quantifiable concentration), AUC0-12, AUC0-inf (area under the plasma concentration curve from time zero extrapolated to infinity), percent AUC extrapolated, kel (elimination rate constant), t1/2 (elimination half-life), CL/F (oral clearance), Vz/F (oral apparent volume of distribution) and Racc (accumulation ratio). |
| Activity of PL225B based on selected biomarkers | Until disease progression or unacceptable toxicity (expected to be 4-6 months) | Plasma samples will be used for analysis of circulating exploratory biomarkers which are likely to change in response to PL225B administration. |
| Objective response | Until disease progression or unacceptable toxicity (expected to be 4-6 months) | Evaluation of Response: Clinical responses will be presented patient wise for different dose levels. |
