Clinical Trial Summary

This is an international, multi-centre, single arm Bayesian designed phase 2 study to identify and determine the safety and activity of anti-IGF-1/IR inhibition in patients with relapsed and/or refractory ESFT. Approximately 40 patients will be recruited from 5-7 European centres. Each patient will be treated with single agent linsitinib, 600 mg orally once a day for days 1-3, 8-10 and 15-17 on a 21 day cycle until disease progression or undue toxicity.


Description:

An important development in ES has been the identification of IGF-1R pathway dependency. The reasons for the remarkable single agent efficacy observed in a small subset of patients remains unknown, as is the relative lack of efficacy in the majority of patients. There may be heterogeneity in response due to partial signal pathway inhibition at the tumour level, inherent resistance in ES cells or the presence of alternative pathway activation through IR-A receptor signalling.

Here we aim to establish pharmacodynamic responses in ES tumours using functional imaging 18FDG-PET-CT and repeat post treatment biopsy for biomarker responses, toxicity and clinical outcome to the dual anti-IGF-1R/IR kinase blocking single agent linsitinib.

This is a single arm phase 2 study utilising adaptive Bayesian analysis. Approximately 40 patients will be recruited the national bone sarcoma centre in 5 EU countries over 18 months.

Eligible patients will take 4x 150 mg tablets once a day, days 1-3 of the week followed by 4 days off - repeated for 3 weeks = one treatment cycle. Patients can remain on treatment for as long as they gain clinical benefit.

The primary objectives are to determine the effect of linsitinib on the patient's tumours in terms of changes in biomarker and PET scans and to establish the safety of the trial drug (linsitinib) in Ewing sarcoma at the dose and treatment schedule being used in the trial.

- Females: Pregnant or breast-feeding, or of childbearing potential unless effective methods of contraception are used. Males: Unless effective methods of contraception are used.

- Significant active cardiac disease including: History (within last 6 months) of significant cardiovascular disease unless the disease is well-controlled. Significant cardiac disease includes second/third degree heart block; clinically significant ischemic heart disease; superior vena cava (SVC) syndrome; poorly controlled hypertension; congestive heart failure of New York Heart Association (NYHA) Class II or worse (slight limitation of physical activity; comfortable at rest, but ordinary physical activity results in fatigue, palpitation, or dyspnea).

- History of arrhythmia (multifocal premature ventricular contractions [PVCs], bigeminy, trigeminy, ventricular tachycardia, or uncontrolled atrial fibrillation) that is symptomatic or requires treatment (= grade 3), left bundle branch block (LBBB), or asymptomatic sustained ventricular tachycardia are not allowed. Patients with atrial fibrillation controlled by medication are not excluded; uncontrolled high blood pressure (no greater than 2 SD above the mean for age for SBP and DBP), unstable angina, congestive heart failure, myocardial infarction within the previous 6 months, or serious cardiac arrhythmias

- 5. Use of drugs that have a known risk of causing Torsades de Pointes (TdP) within 14 days prior to registration

- Use of the potent CYP1A2 inhibitors ciprofloxacin and fluvoxamine within 7 days prior to registration. Linsitinib is primarily metabolized by CYP1A2 and inhibitors/inducers of CYP1A2 could alter the pharmacokinetics of linsitinib. Other less potent CYP1A2 inhibitors/inducers are not excluded

- Other psychological, social or medical condition, physical examination finding or a laboratory abnormality that the Investigator considers would make the patient a poor trial candidate or could interfere with protocol compliance or the interpretation of trial results

- Any other active malignancy, with the exception of adequately treated cone-biopsied in situ carcinoma of the cervix uteri and non-melanoma skin lesions

- History of cerebrovascular accident (CVA) within 6 months prior to entry that resulted in ongoing neurologic instability

- Patients with symptomatic brain metastases. Patients with previously diagnosed brain metastases are eligible if they have completed their CNS treatment and have recovered from the acute effects of radiation therapy or surgery prior to the start of study medication, have discontinued corticosteroid treatment for these metastases for at least 4 weeks, and are neurologically stable

- Major surgery within 4 weeks prior to study treatment

- Prior anti- IGF-1R treatment

- Treatment with any other investigational agent, or participation in another clinical trial within 28 days prior to enrolment

- Patients who are known to be serologically positive for Hepatitis B, Hepatitis C or HIV
