Akt Inhibitor MK2206 in Treating Patients With Advanced Gastric or Gastroesophageal Junction Cancer

Phase 2

Completed

Conditions: Adenocarcinoma of the Gastroesophageal Junction
Diffuse Gastric Adenocarcinoma
Gastric Intestinal Type Adenocarcinoma
Recurrent Gastric Carcinoma
Gastric Mixed Adenocarcinoma

Interventions: Drug: Akt Inhibitor MK2206

Registration Number: NCT01260701

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: This phase II clinical trial studies how well Akt inhibitor MK2206 works in treating patients with advanced gastric or gastroesophageal junction cancer. Akt inhibitor MK2206 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description: PRIMARY OBJECTIVES:

I. To estimate the overall survival (OS) for patients with advanced gastric and gastroesophageal junction (GEJ) adenocarcinoma treated with MK-2206 (Akt inhibitor MK2206).

SECONDARY OBJECTIVES:

I. To estimate the progression free survival (PFS) in this patient population. II. To estimate the response rate (confirmed and unconfirmed complete response \[CR\] and partial response \[PR\] by Response Evaluation Criteria In Solid Tumors \[RECIST\] 1.1) in this patient population.

III. To assess the frequency and severity of toxicity associated with this regimen.

OUTLINE (CLOSED TO ACCRUAL 05/01/13):

Patients receive Akt inhibitor MK2206 orally (PO) every other day on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up every 3 months for 2 years.

Platelets >= 100,000/mcL
Total bilirubin =< institutional upper limit of normal (IULN)
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) both =< 2.5 x IULN; patients with liver metastases must have AST and ALT =< 5 x IULN
Patients must have adequate kidney function as evidenced by at least ONE of the following:
- Serum creatinine (mg/dL) =< IULN obtained within 14 days prior to registration
- Calculated creatinine clearance > 50 ml/min; the serum creatinine value used in the calculation must have been obtained within 14 days prior to registration
Patients must have international normalized ratio (INR) =< 1.2 unless taking therapeutic doses of warfarin; this result must be obtained within 14 days prior to registration
Patients must have fasting blood sugar =< 150 mg/dL within 28 days prior to registration
Patients must have hemoglobin A1C < 7% within 28 days prior to registration
Patients must have an electrocardiogram (ECG) within 28 days prior to registration; patients must have corrected QT interval (QTcF) (by Fridericia's calculation) < 450 msec (male) or < 470 msec (female)
Patients must have a Zubrod performance status of 0-1
Patient must not have any of the following: a history of congenital long QT syndrome; use of concomitant medications that could prolong the QTc interval; New York Heart Association class III or IV heart failure; history of myocardial infarction within 6 months prior to registration; uncontrolled dysrhythmias; poorly controlled angina; resting heart rate =< 50 bpm (bradycardia)
Patients must not be receiving concurrent treatment with drugs that are strong inducers or inhibitors of cytochrome P450 family 3, subfamily A, polypeptide 4 (CYP3A4); patients must be able to safely discontinue treatment with these agents for >= 2 weeks prior to beginning protocol therapy
Patient must not have 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
Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible
Patient must not be pregnant or nursing; women/men of reproductive potential must have agreed to use two forms of contraception for the duration of protocol treatment and for one month after discontinuation of MK-2206; a woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months; in addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation; however, if at any time a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures
No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years
All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines

Study & Design

Study Type: INTERVENTIONAL

Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Treatment (CLOSED TO ACCRUAL 05/01/13)	Akt Inhibitor MK2206	Patients receive Akt inhibitor MK2206 PO every other day on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures

Name	Time	Method
Overall Survival (OS)	Up to 2 years	Overall survival is calculated from date of registration to date of death due to any cause. Patients last known to be alive are censored at date of last contact.

Secondary Outcome Measures

Name	Time	Method
Number of Patients With Grade 3 Through 5 Adverse Events That Are Related to Study Drug	Up to 2 years	Any CTCAE 4.0 event of Grade 3 (severe), Grade 4 (life threatening), or Grade 5 (fatal) which were possibly, probably or definitely related to protocol treatment are included.
Progression Free Survival (PFS)	Up to 2 years	PFS is measured from date of registration to date of first documentation of progression or symptomatic deterioration, or death due to any cause. Patients last known to be alive and without report of progression are censored at date of last contact. Progression is one or more of the following: 20% increase in the sum of appropriate diameters of target measurable lesions over smallest sum observed (over baseline if no decrease during therapy), as well as an absolute increase of at least 0.5 cm; unequivocal progression of non-measurable disease in the opinion of the treating physician; appearance of any new lesion/site; death due to disease without prior documentation of progression and without symptomatic deterioration. Symptomatic deterioration is global deterioration of health status requiring discontinuation of treatment without objective evidence of progression.
Response Rate (Complete and Partial, Confirmed and Unconfirmed)	Up to 2 years	Complete response (CR) is complete disappearance of all target and non-target lesions, no new lesions, and no disease related symptoms. Any lymph nodes must have reduction in short axis to \< 1.0 cm. Partial response (PR) is \>= 30% decrease under baseline of the sum of appropriate diameters of all target measurable lesions, no unequivocal progression of non-measurable disease, and no new lesions. Confirmed CR is two or more statuses of CR a minimum of four weeks apart documented before progression or symptomatic deterioration. Confirmed PR is two or more statuses of PR or better a minimum of four weeks apart documented before progression or symptomatic deterioration, but not qualifying as CR. Unconfirmed CR is one status of CR documented before progression or symptomatic deterioration but not qualifying as CR or PR. Unconfirmed PR is one status of PR documented before progression or symptomatic deterioration but not qualifying as CR, PR or unconfirmed CR.
