Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Tarceva (erlotinib) and Zelboraf (vemurafenib) are the intervention being studied. Both are provided in tablet form and are taken orally everyday until disease progression or unacceptable toxicity (anticipated this will be for approximately 6 months).


There will be 3 dose levels:
a) Dose level D-1 = erlotinib (100 mg/day) and vemurafenib (720 mg twice a day)

b) Dose level D1 = erlotinib (100 mg/day) and vemurafenib (960 mg twice a day)

c) Dose level D2 = erlotinib (150 mg/day) and vemurafenib (960 mg twice a day).

Please note; this is a dose escalation study in the first phase, proceeding to dose expansion in the second phase.

Strategies used to monitor adherence will be via a patient diary, where patients are asked to complete a daily diary entry recording drug use, as well as, standard drug tablet return and accountability logs.

Outcomes
Primary outcome [1] 291941 0
Primary outcome is to determine the safety of the combination of vemurafenib and erlotinib in the first 4 weeks of treatment in BRAF V600E mutant metastatic CRC and identify the dosing regimen to be evaluated in Phase II.

This outcome will be assessed via the incidence of dose-limiting toxicities (DLTs) reported within the first 4 weeks of treatment with the combination of erlotinib and vemurafenib in a cohort of 3 patients. After each cohort of 3 patients completes the DLT observation period, a clinical synthesis of the available toxicity information will be reviewed by the trials safety monitoring committee.
Timepoint [1] 291941 0
Post first 4 weeks of treatment.
Primary outcome [2] 291942 0
Secondary primary outcome is to evaluate the clinical efficacy of the combination of vemurafenib and erlotinib in BRAF V600E mutant metastatic CRC as measured by the proportion of patients achieving a complete or partial response (CR or PR) within the first 24 weeks of treatment.

This outcome will be assessed using the Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 within the first 24 weeks of treatment with the combination of erlotinib and vemurafenib.
Timepoint [2] 291942 0
Post the first 24 weeks of treatment.
Secondary outcome [1] 307885 0

This outcome will be assessed using the Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 within the first 24 weeks of treatment with the combination of erlotinib and vemurafenib.
Timepoint [1] 307885 0
Post the first 24 weeks of treatment.
Secondary outcome [2] 307886 0
To evaluate other measures of clinical efficacy of the combination of vemurafenib and erlotinib in the two patient groups (mCRC, lung adenocarcinoma and other) including: the clinical benefit rate at 16 weeks after treatment commencement (CR, PR and SD).
Timepoint [2] 307886 0
16 weeks after treatment commencement (CR, PR and SD)
Secondary outcome [3] 307887 0

Safety will be assessed throughout various timepoints during treatment and will include the following investigations:
a) Physical examination;
b) Haematology assessments;
c) Biochemistry assessments;
d) Performance status assessments;
e) ECGs
f) Toxicity assessments;
g) Tumour response assessments according to RECIST v1.1
h) FDG-PET (where applicable).
Timepoint [3] 307887 0
Assessments will occur at various timepoints throughout the study, and include (but are not limited to):

a) Screening;
b) Weeks 1,2,4,6,8,12,16,20 and 24; and
c) Every 8 weeks thereafter until end of treatment.

Eligibility
Key inclusion criteria
1. Male or female patients greater than or equal to 18 years of age at the time of study entry
2. All patients must have histological or cytological confirmed metastatic colorectal cancer with a BRAF V600E mutation of their primary cancer or related metastases. Patients with other tumour types with a proven BRAF V600E mutation can be considered for enrolment into the Expansion Phase exploratory cohort with the permission of the Study Chair.
3. Patients with BRAF V600E mCRC are permitted to have had a maximum of 2-lines of therapy for metastatic disease. A maintenance strategy post 1st-line treatment is not considered as an additional line of therapy, nor is rechallenge with oxaliplatin. Patients with lung adenocarcinoma are required to have received prior treatment with a platinum doublet. There is no requirement for previous treatment for other tumour types.
4. All patients must have measurable disease per RECIST 1.1 criteria.
5. A tumour paraffin tissue block or 20 - 30 unstained slides from the tumour tissue block must be available for the purpose of biomarker analyses. Obtaining archived tumour material or unstained slides from an archived tumour block will suffice to meet this requirement. The availability of the tumour tissue block must be confirmed at screening for a patient to be considered eligible. If no tissue block and fewer than 20 unstained slides are available, eligibility must be confirmed with the Study Chair or delegate.
6. ECOG performance status 0 to 1 inclusive.
7. Participants must have adequate organ and marrow function as defined below:
a) Absolute neutrophil count greater than or equal to 1.5 x 109/L
b) Platelets greater than or equal to 100 x 109/L
c) ALT and AST less than or equal to 2.5 x upper limit of normal (ULN), or less than or equal to 5 x ULN if liver metastases are present
d) Total serum bilirubin less than or equal to 1.5 x ULN
e) Serum creatinine less than or equal to 1.5 x ULN, or creatinine clearance > 50ml/min
8. Participants must be suitable for oral drug administration.
9. Life expectancy > 3 months.
10. Female patients of childbearing potential (see below) must:
a) Be on highly effective contraception. Highly effective contraception methods include:
* total abstinence, or
* sterilisation (see below), or
* combination of any two of the following (a+b, or a+c, or b+c):
* Use of oral, injected or implanted hormonal methods of contraception. Hormonal contraceptives include any marketed contraceptive agent that includes an oestrogen and/or a progestin.
* Placement of an intrauterine device (IUD)
* Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/cream/ vaginal suppository
b) Have a negative serum or urine pregnancy test performed within the 7 days before start of treatment.
c) Highly effective contraception for females of child bearing potential must be maintained throughout the study and for 6 months after study drug discontinuation.
11. Female patients not of child-bearing potential. Women are considered not of child bearing potential if they have had either:
a) 12 months of natural (spontaneous) amenorrhoea with an appropriate clinical profile (eg. age appropriate, history of vasomotor symptoms), or
b) A surgical bilateral oophorectomy (with or without hysterectomy), or
c) Tubal ligation at least 6 weeks ago.
In the case of unilateral oophorectomy alone, a woman is considered not of child-bearing potential only once the reproductive status has been confirmed by follow up hormone level assessment.
12. Sexually active males must use a condom during intercourse while taking the drug and for 6 months after stopping treatment and should not father a child in this period. A condom is required to be used also by vasectomised men in order to prevent delivery of the drug via seminal fluid.
13. Absence of any psychological, familial or sociological condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before trial entry.
14. Ability to understand and the willingness to sign a written informed consent. Before study entry, written informed consent must be obtained from patient prior to performing any study-related procedures.

2. History of or known spinal cord compression, or carcinomatous meningitis.
3. Patients who have had any systemic cytotoxic/biologic or investigational therapies within 4 weeks prior to study entry or who have not recovered from the side effects of such earlier therapy.
4. Previous malignancies within the past 5 years are excluded except for adequately treated carcinoma in-situ of the cervix. Isolated elevation in PSA in the absence of radiographic evidence of metastatic prostate cancer is allowed.
5. Participants who have had radiotherapy and/or major surgery within 2 weeks prior to study entry.
6. Anticipated or concurrent use of any other anti-cancer therapies or study agents.

10. Known history of active hepatitis B or C.
11. Other severe, acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, which in the judgment of the investigator would make the patient inappropriate for entry into this study.
12. Patients who are receiving treatment with medications known to be strong CYP3A4 inhibitors within 7 days before starting treatment with erlotinib and vemurafenib or strong inducers of CYP3A4 within 14 days before starting treatment with erlotinib and vemurafenib.
A comprehensive list of inhibitors, inducers and substrates may be found at http://medicine.iupui.edu/flockhart/table.htm.
13. Nursing (lactating) women.
