An Open Label, Two-Part, Phase Ib/II Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of the MEK Inhibitor Trametinib and the BCL2-Family Inhibitor Navitoclax (ABT-263) in Combination in Subjects With KRAS or NRAS Mutation-Positive Advanced Solid Tumors

This phase Ib/II trial studies the side effects and best dose of trametinib and navitoclax
and how well they work in treating patients with solid tumors that have spread to other
places in the body. Trametinib and navitoclax may stop the growth of tumor cells by blocking
some of the enzymes needed for cell growth.

PRIMARY OBJECTIVES:

I. To determine the dose-limiting toxicities of trametinib in combination with navitoclax,
and the maximal doses at which both drugs can be safely administered together. (Phase Ib) II.
To determine the response rate of the combination of trametinib and navitoclax in subjects
with KRAS or NRAS mutation-positive advanced or metastatic solid tumors in disease-specific
expansion cohorts. (Phase II) III. To confirm the safety and tolerability of trametinib and
navitoclax in combination at the recommended phase 2 dose (RP2D) determined in the Phase 1b
portion. (Phase II)

SECONDARY OBJECTIVES:

I. To determine the pharmacokinetics of both drugs administered together. (Phase Ib) II. To
assess for evidence of response to therapy. (Phase Ib) III. To evaluate the pharmacodynamic
response to therapy in tumor biopsies. (Phase Ib) IV. To evaluate the pharmacodynamic
response to therapy in tumor biopsies (first 15 patients enrolled overall). (Phase II)

OUTLINE: This is a phase Ib, dose-escalation study followed by a phase II study.

Patients receive trametinib orally (PO) once daily (QD) and navitoclax PO QD on days 1-28.
Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
If unacceptable toxicity is observed, patients may receive trametinib PO QD on days 1-14.

After completion of study treatment, patients are followed up for 30 days.

Inclusion Criteria:

- Patients must have histologically- or cytologically-confirmed diagnosis of KRAS or
NRAS mutation-positive malignancy that is metastatic or unresectable and for which
standard curative measures do not exist or are no longer effective; patients must have
activating mutations affecting codons 12, 13, 61, or 146 as determined in a Clinical
Laboratory Improvement Amendments (CLIA)-certified lab to be eligible for this study

- Patients must have measurable disease by Response Evaluation Criteria in Solid Tumors
(RECIST), defined as at least one lesion that can be accurately measured in at least
one dimension (longest diameter to be recorded for non-nodal lesions and short axis

must have experienced documented radiographic progression or intolerance on this
therapy

- Paired pre-treatment and post-treatment biopsies are required for all patients on Part
1 and first 15 patients in Part 2; participants must have available archival tumor
tissue (at least 20 unstained slides); if archival tissue is not available or is found
not to contain tumor tissue, a fresh biopsy is required; if a patient is having a
tumor biopsy, less than 20 unstained slides are acceptable with approval of the
principal investigator (PI); biopsies will only be performed in a given patient if
they are not deemed to involve unacceptable risk based on the sites of disease and
other concurrent medical conditions

pregnant or suspect she is pregnant while she or her partner is participating in this
study, she should inform her treating physician immediately; the potential hazard to

shorter; with a minimum of 14 days from the last dose) preceding the first dose of
study drug(s) and during the study

therapies are prohibited:

- Other anti-cancer therapy while on study treatment; (note: megestrol [Megace] if
used as an appetite stimulant is allowed)

be initiated prior to the first dose of study therapy; prophylactic use of
bisphosphonates in patients without bone disease is not permitted, except for the
treatment of osteoporosis

- The concurrent use of all herbal supplements is prohibited during the study
(including, but not limited to, St. John's wort, kava, ephedra [ma huang], ginkgo
biloba, dehydroepiandrosterone [DHEA], yohimbe, saw palmetto, or ginseng)

administration: warfarin, clopidogrel (Plavix), ibuprofen, tirofiban (Aggrastat),
and other anticoagulants, drugs, or herbal supplements that affect platelet
function are excluded, with the exception of low-dose anticoagulation medications
(such as heparin) that are used to maintain the patency of a central intravenous
catheter; aspirin will not be allowed within 7 days prior to the first dose of
navitoclax or during navitoclax administration; however, subjects who have
previously received aspirin therapy for thrombosis prevention may resume a low
dose (i.e., maximum 100 mg QD) of aspirin if platelet counts are stable (>=
50,000/mm^3) through 6 weeks of navitoclax administration; all decisions
regarding treatment with aspirin therapy will be determined by the investigator
in conjunction with the medical monitor

- Caution should be exercised when dosing navitoclax concurrently with cytochrome P450,
family 2, subfamily C, polypeptide 8 (CYP2C8) and cytochrome P450, family 2, subfamily

patients closely (particularly in the case of medications that have a narrow
therapeutic window such as warfarin; use of warfarin is specifically prohibited while
on study); cytochrome P450, family 3, subfamily A (CYP3A) inhibitors such as
ketoconazole and clarithromycin are not allowed 7 days prior to the first dose of
navitoclax or during navitoclax administration; as part of the enrollment/informed
consent procedures, the patient will be counseled on the risk of interactions with
other agents, and what to do if new medications need to be prescribed or if the
patient is considering a new over-the-counter medicine or herbal product; patient
instructions and information of possible drug interactions will be given to all
patients upon enrollment in this study
