Summary
This phase I trial studies the side effects and best dose of Akt inhibitor MK2206 and lapatinib ditosylate when given together with trastuzumab in treating patients with locally advanced or metastatic human epidermal growth factor receptor-2 (HER2)-positive breast, gastric, or gastroesophageal cancer that cannot be removed by surgery. Akt inhibitor MK2206 and lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for tumor growth. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving Akt inhibitor MK2206 and lapatinib ditosylate together with trastuzumab may kill more tumor cells.

Criteria
Inclusion Criteria:

- Patients must have histologically confirmed HER2-positive invasive breast, gastric, or
gastroesophageal carcinoma that is locally advanced and unresectable or metastatic and
for which standard curative or palliative measures do not exist or are no longer
effective; HER2-positive is defined as HER2 overexpression and/or amplification as
determined by immunohistochemistry (3+) or fluorescence in situ hybridization (FISH)
(>= 2.0)

- Patients must have measurable disease, 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 for nodal lesions) as >= 20 mm with conventional
techniques or as >= 10 mm with spiral computed tomography (CT) scan

- Patients may have previously received trastuzumab or lapatinib as part of a regimen in
the adjuvant or metastatic setting with evidence of progression

- No restriction on prior chemotherapy regimens for advanced stage disease; no
restriction for prior hormonal therapy

- Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)

- Life expectancy of greater than three months

- Left ventricular ejection fraction (LVEF) by multi-gated radionuclide angiography scan
(MUGA) or echocardiogram (ECHO) at or above the lower limit of normal of 50%

- Leukocytes >= 3,000/mcL

- Absolute neutrophil count >= 1,000/mcL

- Platelets >= 100,000/mcL

- Total bilirubin within normal institutional limits

- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase
[SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase [SGPT])
=< 2.5 X institutional upper limit of normal

- Creatinine within normal institutional limits OR creatinine clearance >= 60
mL/min/1.73 m^2 for patients with creatinine levels above institutional normal

- The effects of MK-2206 on the developing human fetus are unknown; for this reason,
women of child-bearing potential and men must agree to use adequate contraception
(hormonal or barrier method of birth control; abstinence) prior to study entry and for
the duration of study participation; should a woman become pregnant or suspect she is
pregnant while she or her partner is participating in this study, she should inform
her treating physician immediately

- Patients must be able to swallow whole tablets; nasogastric or gastrostomy (G) tube
administration is not allowed; tablets must not be crushed or chewed

- Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for
nitrosoureas or mitomycin C) prior to entering the study or those who have not
recovered from adverse events due to agents administered more than 4 weeks earlier; if
the patient has residual toxicity from prior treatment, toxicity must be =< grade 1

- Patients who are receiving any other investigational agents; no concurrent use of
endocrine therapy is permitted; patients on bisphosphonates or denosumab for bone
metastases or osteopenia/porosis are considered eligible

- Patients with active brain metastases requiring radiation should be excluded as they
may develop progressive neurologic dysfunction that would confound the evaluation of
neurologic and other adverse events; patients with stable brain metastases (mets) (> 6
months without change in steroids or seizure medications) will be considered eligible

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to MK-2206, trastuzumab, or lapatinib

- Patients receiving any medications or substances that are inhibitors or inducers of
cytochrome P450 3A4 (CYP450 3A4) are ineligible

- Preclinical studies demonstrated the potential of MK-2206 for induction of
hyperglycemia in all preclinical species tested; patients with diabetes or in risk for
hyperglycemia should not be excluded from trials with MK-2206, but the hyperglycemia
should be well controlled on oral agents or insulin before the patient enters the
trial; patients with poorly controlled diabetes with hemoglobin (Hgb)A1C > 9% will be
excluded

- Preclinical studies indicated transient changes in corrected QT interval (QTc)
interval during MK-2206 treatment; prolongation of QTc interval is potentially a
safety concern while on MK-2206 therapy; cardiovascular baseline QTc > 480 msec will
exclude patients from entry on study

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements

- Pregnant women are excluded from this study because MK-2206 an agent with the
potential for teratogenic or abortifacient effects; because there is an unknown but
potential risk for adverse events in nursing infants secondary to treatment of the
mother with MK-2206, breastfeeding should be discontinued if the mother is treated
with MK-2206; these potential risks may also apply to other agents used in this study

- Patients with unstable angina, congestive heart failure, or with a history of a
myocardial infarction within 6 months; patients with high-risk uncontrolled
arrhythmias (ventricular tachycardia, high-grade atrioventricular [AV] block,
supraventricular arrhythmias which are not adequately rate-controlled); patients with
uncontrolled hypertension (i.e., over 160/90 mmHg); patients who are controlled on
anti-hypertensive medication will be allowed to enter the study

- Patients known to be human immunodeficiency virus (HIV)-positive and are on
combination antiretroviral therapy are ineligible because of the potential for
pharmacokinetic interactions with MK-2206; in addition, these patients are at
increased risk of lethal infections when treated with marrow-suppressive therapy and
as such patients with cluster of differentiation (CD)4 counts < 200 will be excluded;
HIV-positive patients not on anti-retrovirals and with an adequate CD4 count will be
considered eligible
