Akt Inhibitor MK2206 in Treating Patients With Advanced Gastric or Gastroesophageal Junction Cancer
|Adenocarcinoma of the Gastroesophageal Junction Diffuse Gastric Adenocarcinoma Gastric Intestinal Type Adenocarcinoma Gastric Mixed Adenocarcinoma Recurrent Gastric Carcinoma||Drug: Akt Inhibitor MK2206||Phase 2|
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Phase II Study of MK-2206 (NSC-749607) as Second Line Therapy for Advanced Gastric and Gastroesophageal Junction Cancer|
- Overall Survival (OS) [ Time Frame: 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.
- Progression Free Survival (PFS) [ Time Frame: 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) [ Time Frame: 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.
- Number of Patients With Grade 3 Through 5 Adverse Events That Are Related to Study Drug [ Time Frame: 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.
|Study Start Date:||January 2011|
|Study Completion Date:||July 2015|
|Primary Completion Date:||May 2014 (Final data collection date for primary outcome measure)|
Experimental: Treatment (CLOSED TO ACCRUAL 05/01/13)
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.
Drug: Akt Inhibitor MK2206
Other Name: MK2206
I. To estimate the overall survival (OS) for patients with advanced gastric and gastroesophageal junction (GEJ) adenocarcinoma treated with MK-2206 (Akt inhibitor MK2206).
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.
