A Multiple Dose, Dose Escalation Trial of AEB1102 in Patients With Advanced Solid Tumors

In this phase I multiple dose, dose escalation study utilizing a classic 3+3 design.
Sequential cohorts of patients will receive AEB1102 IV weekly at one of a series of
increasing dose levels. Dose escalation will be dependent on the frequency of specific
dose-limiting toxicities in the prior cohort of patients. The study will determine the
maximum tolerated dose (MTD) of AEB1102, evaluate the safety profile of the compound, assess
the pharmacokinetic profile of AEB1102, determine the effect of AEB1102 on blood arginine
levels and evaluate the anti-tumor activity of AEB1102.

Following the determination of the MTD, additional cohorts of patients with uveal, cutaneous
melanoma and small cell lung cancer will be enrolled and treated with AEB1102 at the MTD.

Inclusion Criteria:

For patients participating in any part of the trial:

- has an advanced solid tumor previously treated with, or inability to tolerate,
standard therapy for the disease, or for which a standard therapy does not exist, and
as such is considered a candidate for Phase 1 treatment

- has adequate organ function: Hgb ≥9 g/dL; absolute neutrophil count (ANC) ≥ 1.5x109/L;
plt ≥ 100,000/μL; AST and ALT < 2.5x ULN (< 5x ULN in patients with liver metastases);
total bilirubin < 2.0 mg/dL; serum creatinine ≤ 1.5x ULN

- ECOG performance score 0-2

For patients participating in any expansion group:

- has measurable disease based on RECIST 1.1 as determined by the treating investigator.
Tumor lesions in a previously irradiated area are considered measurable if progression
has been demonstrated in such lesions

- willing to consent for biopsy is strongly recommended but not mandatory

- recovery of toxicities related to any prior treatments to at least Grade 1 by CTCAE v
4.03. Exceptions are patients with adverse event(s) that are clinically nonsignificant
and/or stable on supportive therapy.

For patients participating in specific expansion groups:

Cutaneous Melanoma:

- unresectable, locally advanced or metastatic (AJCC stage IIIB, IIIC, or IV) cutaneous
malignant melanoma

- relapsed or progressive disease after or unable to tolerate at least one prior
systemic anticancer regimen for metastatic disease involving immunotherapy (anti-PD-1,
anti-PD-L1, or anti-CTLA-4)

- in tumors with a relevant BRAF mutation, relapsed, refactory, or unable to tolerate at
least one prior systemic anticancer regimen for metastic disease involving a BRAF
inhibitor

Uveal Melanoma:

- uveal melanoma at metastic stage

Small Cell Lung Cancer:

- extensive disease previously treated with, or inability to tolerate, platinum-based
chemotherapy

Exclusion Criteria:

- has primary CNS malignancy

- history of untreated brain mets or leptomeningeal disease or spinal cord compression

- effects of prior anticancer therapy recovered to grade < 2

- known HIV

- active infection

- major surgery within 2 weeks

- history of another malignancy within 2 years prior
