NCT ID: NCT01586624

Last Updated: 2021-10-07

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 61 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2012-01-10
• Study Completion Date: 2020-06-11

Brief Summary

The purpose of this study is to determine whether using two drugs together called vandetanib and selumetinib is effective in the treatment of cancer. The first part of this study will include patients with any solid tumour and the second part of this study will include only patients with non small cell lung cancer. The four main aims of this clinical study are to find out:

• If the two drugs can be given safely to patients when given together.
• The maximum dose that can be given safely to patients.
• More about the potential side effects of the drugs and how they can be managed.
• What happens to vandetanib and selumetinib inside the body.

Detailed Description

The purpose of this Phase I study is to establish a safety and toxicity profile of combining two study drugs; vandetanib, a VEGFR (Vascular Endothelial Growth Factor Receptor) and EGFR (Epidermal Growth Factor Receptor) inhibitor, with selumetinib a MEK (Mitogen Activated Kinase) inhibitor.

This is the first time the drugs have been used together. These types of drugs have shown an effect in non small cell lung cancer (NSCLC).

The study is in two parts; the dose escalation phase and the expansion phase.

In the dose escalation phase, 42-50 patients will receive different doses of vandetanib and increasing doses of selumetinib to establish a safe dose to recommend for the next stage of the study. Patients with any solid tumour will be eligible.

In the expansion phase, up to 30 patients will receive the dose recommended in the previous phase. Only patients with NSCLC will be eligible for this part of the study.

The expansion phase will look at further evaluating the safety of the drug combination and the anti-tumour activity. Patients in this cohort will be requested to also consent to have additional imaging assessments and optional tumour biopsies.

Study treatment is administered orally; vandetanib tablets once daily and selumetinib capsules once daily (OD)/twice daily (BD). Cycle 1 is 42 days long. Subsequent cycles are 28 days in length. Patients will receive a total of 6 cycles of the combination treatment. If the patient has not progressed after six cycles, they may be treated for further cycles following approval from the sponsor.

8. 18 years or over

9. Ability to swallow and retain oral medications.

10. Written (signed and dated) informed consent and be capable of co-operating with treatment, and follow-up

Exclusion Criteria

1. Radiotherapy (except for palliative reasons), endocrine therapy, immunotherapy or chemotherapy during the previous 4 weeks (6 weeks for investigational medicinal products) before treatment.

7. Patients with interstitial lung disease.

8. Pregnant or lactating women are excluded. Female patients with the ability to become pregnant who have a negative serum or urine pregnancy test before enrollment and agree to use two of the following three highly effective forms of combined contraception (oral, injected or implanted hormonal contraception and condom, have a intra-uterine device and condom, diaphragm with spermicidal gel and condom) for four weeks before entering the trial, during the trial and for six months afterwards are considered eligible.

9. Male patients with partners of child-bearing potential (unless they agree to take measures not to father children by using one form of highly effective contraception [condom plus spermicide] during the trial and for six months afterwards). Men with pregnant or lactating partners should be advised to use barrier method contraception (e.g. condom plus spermicidal gel) to prevent exposure to the foetus or neonate.

10. Major surgery from which the patient has not yet recovered.

11. At high medical risk because of non-malignant systemic disease including active uncontrolled infection.

• Uncontrolled hypertension (BP > 160/100 despite optimal therapy)
• Prior or current cardiomyopathy
• Atrial fibrillation with heart rate > 100 bpm
• QTcB > or equal to 450 msec on screening ECG (Note: If a patient has a QTcB interval > or equal to 450 msec on screening ECG, the screen ECG may be repeated twice [at least 24 hours apart]. The average QTcB from the three screening ECGs must be < 450 msec in order for the subject to be eligible for the study.)
• History of congenital long QT syndrome
• History of Torsade de Pointes (or any concurrent medication with a known risk of inducing Torsades de Pointes.)

14. Concomitant medications that are potent inducers of CYP3A4 function i.e. rifampicin, rifabutin, phenytoin, carbamazepine, Phenobarbital and St John"s Wort.

15. Any other condition which in the Investigator"s opinion would not make the patient a good candidate for the clinical trial (e.g. evidence of severe or uncontrolled systemic disease or concurrent condition or that may affect ability to absorb oral agents).

16. Current malignancies of other types, with the exception of adequately treated cone-biopsied in situ carcinoma of the cervix uteri and basal or squamous cell carcinoma of the skin. Cancer survivors, who have undergone potentially curative therapy for a prior malignancy, have no evidence of that disease for five years or more and are deemed at negligible risk for recurrence, are eligible for the trial.

17. If a participant plans to participate in another interventional clinical study, whilst taking part in this Phase I study. Participation in an observational study would be acceptable.

18. Ophthalmological conditions as follows:

1. Current or past history of retinal pigment epithelial detachment (RPED)/central serous retinopathy (CSR) or retinal vein occlusion.
