- Haemoglobin (Hb) ≥ 9g/dl (transfusion to achieve this allowed ),
- Neutrophils ≥ 1,500/μl,
- Platelet count ≥ 100,000/μl,
- AST or ALT ≤ 2.5 x ULN, patient with liver metastases ≤ 5 × ULN,
- Alkaline phosphatase ≤ 5 x ULN,
- Serum Bilirubin ≤ 1.5 x ULN,
- Creatinine Clearance ≥ 50ml/min (Calculated by Cockcroft Gault equation, or by EDTA) (Appendix 2)
- Able to swallow oral medication
- Life expectancy of at least 3 months.
Dose escalation phase:
- Patients with any advanced solid tumours
- Patients for whom the combination of PF-02341066 with Binimetinib is a reasonable option.
Dose expansion phase:
Patients will be eligible for pre-screening for this phase provided that:
- They have given informed consent to screening.
- They are willing to undergo a biopsy for assessment of tumour RAS mutation status and c-MET assessment.
- The Investigator anticipates that they are likely to satisfy the eligibility criteria for the trial. Formal screening should not be performed until the tumour pre-screening result is known.
Eligibility for the trial, in patients passing pre-screening, requires:
- Histologically confirmed colorectal adenocarcinoma that is either a) RASMT (KRAS codon 12, 13, 61, 117, 146; NRAS codon 12, 13, 61, 117, 146) or b) RASWT/c-MET mutated/amplified or c) RASWT/c-MET over-expressed with progressive disease on or within 6 months of completion of adjuvant therapy or after chemotherapy and/or targeted therapies for metastatic disease.
- Prior treatment with an EGFR targeted monoclonal antibody for patients with RASWT/c-MET mutated or amplified CRC or c) RASWT/c-MET over-expressed CRC.
- No evidence for a mutation in BRAF at codon600
- Metastases accessible for biopsy on 2-3 occasions
- At least one other measurable lesion (according to RECIST v1.1).
- Unsuitable for potential curative resection. ┼For non-UK territories: if echocardiogram (ECHO) cannot be performed, a MUGA scan may be performed in compliance with local policy, applicable national legislation and relevant approvals. Cardiac ejection fraction must be determined as measured by ECHO in the UK.
EXCLUSION CRITERIA (
for the completed initial dose escalation phase
using PF-02341066/PD-0325901 are listed in Appendix 7.) All patients
- Unstable ischaemic heart disease, cardiac dysrhythmias, coronary/peripheral artery
bypass graft or cerebrovascular accident within 6 months prior to starting treatment.
- Uncontrolled arterial hypertension despite medical treatment.
- Ongoing congestive heart failure or cardiac dysrhythmias of NCI CTCAE Grade ≥2 or
uncontrolled atrial fibrillation.
- History of extensive disseminated/bilateral or known presence of Grade 3 or 4
interstitial fibrosis or interstitial lung disease, including a history of
pneumonitis, hypersensitivity pneumonitis, interstitial pneumonia, interstitial lung
disease (ILD), obliterative bronchiolitis, and pulmonary fibrosis. A history of prior
radiation pneumonitis is allowed.
- Any active central nervous system (CNS) lesion (i.e., those with radiographically
unstable, symptomatic lesions) and/or leptomeningeal metastases. However, patients
treated with stereotactic radiotherapy or surgery are eligible if the patient remained
without evidence of CNS disease progression ≥ 3 months. Patients must be off
corticosteroid therapy for ≥ 3 weeks.
- Patients who have neuromuscular disorders that are associated with elevated CK (e.g.,
inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal
- Patients who are planning on embarking on a new strenuous exercise regimen after first
dose of study treatment. NB: Muscular activities, such as strenuous exercise, that can
result in significant increases in plasma CK levels should be avoided while on
- Spinal cord compression unless treated with the patient attaining good pain control
and stable or recovered neurologic function.
- Carcinomatous meningitis or leptomeningeal disease.
- History of hypoalbuminaemia, or patients with peritoneal disease or pleural disease,
where there is a requirement for ascitic or pleural taps.
- History of retinal vein occlusion, intraocular pressure > 21 mmHg or patient
considered at risk of retinal vein thrombosis (e.g. history of hyperviscosity or
- History of retinal degenerative disease.
- History of Gilbert's syndrome.
- Active infections (including chronic hepatitis type B or C and HIV infection if status
known), severe immunologic defect, compromised bone marrow function.
- Other severe acute or chronic medical (including severe gastro-intestinal disorders
e.g. partial bowel obstruction, malabsorption, active inflammatory bowel disease) or
psychiatric conditions or laboratory abnormalities that the investigator considers
would make the patient a poor trial candidate, would impart excess risk associated
with study participation or drug administration or could interfere with protocol
compliance or the interpretation of trial results.
- Patients who have undergone major surgery ≤ 3 weeks prior to starting study drug or
who have not recovered from side effects of such procedure.
- Use of drugs or foods that are known potent CYP3A4 inhibitors or inhibitors or are
CYP3A4 substrates with narrow therapeutic indices (see Appendix 5).
- Radiotherapy (except for palliative reasons), endocrine therapy, immunotherapy or
chemotherapy during the previous four weeks (six weeks for nitrosoureas, Mitomycin-C)
and four weeks for investigational medicinal products before treatment. Patients with
prostate cancer may continue to receive endocrine therapy to maintain castrate levels
- Resting ECG with QTc > 480msec at 2 or more time points within a 24h period (using
- Requirement for medication known to prolong QT interval (Appendix 5).
- History of other malignancy less than 3 years before the diagnosis of current cancer,
EXCLUDING the following: Non-melanoma skin cancer, in situ carcinoma of the cervix
treated surgically with curative intent, other malignant tumours that have been
treated curatively and patient is deemed disease-free
- Women with the ability to become pregnant (or already pregnant or lactating). However,
those female patients who have a negative serum pregnancy test before enrolment and
agree to use one highly effective form of contraception (oral, injected or implanted
hormonal contraception or intra-uterine device) in addition to condom plus spermicide
for four weeks before entering the trial, during the trial and for six months
afterwards are considered eligible.
- 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
including oral, injected or implanted hormonal contraception or intra-uterine device
in addition to 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 (condom plus spermicidal gel) to prevent exposure to the foetus
- Prior exposure to any of a HGF, cMET or a MEK inhibitor.
