About this study
Official title: A Phase 2 Trial of MLN0264 in Previously Treated Patients With Metastatic or Recurrent Adenocarcinoma of the Stomach or Gastroesophageal Junction Expressing Guanylyl Cyclase C (GCC)
The purpose of this study is to assess the efficacy, safety and tolerability of MLN0264 in patients with recurrent or metastatic guanylyl cyclase C (GCC)-positive adenocarcinoma of the stomach or gastroesophageal junction.
Read the detailed description
The drug being tested in this study is called MLN0264. MLN0264 is being tested to treat tumors in people who have metastatic or recurrent gastric or gastroesophageal junction malignancies expressing guanylyl cyclase C (GCC). Participants will be analyzed in cohorts based on GCC expression: low=combined H-score 10-109, intermediate=combined H-score 110-249, high=combined IHC H-score >250. This study will assess tumor size reduction in patients who are administered MLN0264.
The study enrolled 38 patients. All participants will be administered MLN0264 at 1.8 mg/kg as a single, 30-minute, intravenous (IV) infusion on Day 1 of each 3-week treatment cycle, followed by a rest period of 20 days. Participants will continue to receive MLN0264 for up to 1 year or until disease progression or unacceptable toxicity occurs.
This multi-centre trial will be conducted worldwide. The overall time to participate in this study is approximately 19 months. Participants will make 3 to 6 visits to the clinic per treatment cycle, an end-of-treatment visit 30 days after the last dose of study medication, and follow-up assessments every 12 weeks until death or 6 months after the last patient completes treatment - whichever occurs first.

What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Response Rate (ORR) Based on Response Evaluation Criteria in Solid Tumors (RECIST)
ORR is defined as the percentage of participants with complete response (CR) or partial response (PR) as assessed by the investigator using Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. CR: Disappearance of all target lesions, non-target lesions, no new lesions, and normalization of tumor marker level. PR: At least a 30% decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesions.
Measured: Day 21, every other cycle, starting with Cycle 2 until disease progression, death or study closure (up to 17 months)
Secondary outcomes (14)
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) is defined as any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect or is a medically important event. Relationship of each AE to study drug will be determined by the Investigator.
Measured: From the first dose through 30 days after the last dose of study medication (Up to 10.7 months)
Number of Participants With Potentially Clinically Significant Laboratory Evaluation Findings
Participants with at least one post-baseline potentially clinically significant serum chemistry, hematology, coagulation or urinalysis result. Clinically significant results are those that were assessed by the investigator to be Grade 3 or higher using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE). Grade 3=severe, Grade 4=life threatening or disabling and Grade 5=Death.
Measured: From the first dose through 30 days after the last dose of study medication (Up to 10.7 months)
Number of Participants With Potentially Clinically Significant Vital Signs Findings
Participants with at least one potentially clinically significant post-baseline vital sign finding including measurements of diastolic and systolic blood pressure, heart rate, and oral temperature.
Measured: Day 1 of each 21 day cycle and 30 days after the last dose of study medication (Up to 10.7 months)
Progression Free Survival (PFS)
PFS is defined as the time in days from the date of first study drug administration to the date of first documentation of disease progression or death. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
Measured: Time Frame: Day 21 of every other 21-day cycle starting with Cycle 2, 30 days after the last dose of study medication, and then every 12 weeks for up to an additional 6 months (Up to 16.7 months)
Duration of Response
Duration of response is defined as the time in days from the date of first documentation of a confirmed response to the date of first documentation of disease progression. Per RECIST v1.1 for target lesions and assessed by magnetic resonance imaging (MRI) - CR: Disappearance of all target lesions, non-target lesions, no new lesions, and normalization of tumor marker level. PR: At least a 30% decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesions.
Measured: From first documented response until disease progression (Up to 16.7 months)
Disease Control Rate
Disease control rate is defined as the percentage of participants with complete response (CR) or partial response (PR) or stable disease (SD) with a minimum of 12 weeks' duration. CR: Disappearance of all target lesions, non-target lesions, no new lesions, and normalization of tumor marker level. PR: At least a 30% decrease in the sum of the Longest Diameter (LD) of target lesions, taking as reference the baseline sum LD and no new lesions. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD) of target lesions, taking as reference the smallest sum LD since the treatment started and no new lesions. Investigator response is based on the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.
Measured: Day 21 of every other 21-day cycle starting with Cycle 2, 30 days after the last dose of study medication, and then every 12 weeks for up to an additional 6 months (Up to 16.7 months)
Overall Survival (OS)
Overall survival is defined as the time in days from the date of first study drug administration to the date of death.
Measured: Until death or 6 months after the last patient completes treatment-whichever occurs first (Up to 17 months)
Cmax: Maximum Observed Serum Concentration for MLN0264
Maximum observed serum concentration (Cmax) is the peak serum concentration of a drug after administration, obtained directly from the serum concentration-time curve.
Measured: Cycles 1-3 predose and 10 minutes, 4 hours, and 3, 4, 8 and 15 days postdose. Cycles 4+ predose, 10 minutes, 4 hours, and 4 and 8 days postdose.
MLN0264 Serum Concentrations
Blood samples were collected and sent to a laboratory to be tested for serum concentrations of MLN0264.
Measured: Cycles 1-3 pre-dose and 10 minutes, 4 hours, and 3, 4, 8 and 15 days post-dose; Cycles 4-9 and 11-14 pre-dose and 10 minutes post-dose; End of Treatment.
Serum Concentration of Total Antibodies (Conjugated and Unconjugated)
Blood samples were collected and sent to a laboratory to be tested for conjugated and unconjugated antibodies.
Measured: Cycles 1-3 pre-dose and 10 minutes, 4 hours, and 3, 4, 8 and 15 days post-dose; Cycles 4-9 and 11-14 pre-dose and 10 minutes post-dose; End of Treatment.
Serum Concentration of Monomethyl Auristatin E (MMAE)
Blood samples were collected and sent to a laboratory to be tested for MMAE.
Measured: Cycles 1-3 pre-dose and 10 minutes, 4 hours, and 3, 4, 8 and 15 days post-dose; Cycles 4-9 and 11-14 pre-dose and 10 minutes post-dose; End of Treatment.
Number of Participants With Reduction From Baseline in Tumor Size
The number of participants with the best percentage of tumor reduction from baseline in the sum of the diameter was calculated.
Measured: Day 21 of every other 21-day cycle starting with Cycle 2, 30 days after the last dose of study medication, and then every 12 weeks for up to an additional 6 months (Up to 16.7 months)
Guanylyl Cyclase C (GCC) H-score Assessed by Immunohistochemistry (IHC)
Analysis of GCC protein expression levels in tumor tissue (fresh biopsy pretreatment and whenever a biopsy is considered medically safe and technically feasible) was performed using a semiquantitative immunohistochemistry (IHC) assay and the total GCC H-Score was determined. GCC H-score is based on the sum of the 0 to 300 H-score for cytoplasmic staining and the 0 to 300 H-score for apical staining for a total possible H-score 0 to 600. Separate consent was required to obtain archival tumor specimens for GCC expression assessment prior to screening.
Measured: Approximately 20 months
Number of Participants With Antitherapeutic Antibodies (ATA)
Blood samples were collected to assess the immunogenicity of MLN0264 (ATA development) using a laboratory test. Neutralizing ATA assessment was performed for ATA-positive samples only.
Measured: Pre-dose of each 21 day cycle and 30 days after last dose of study medication (Up to 10.7 months)

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 27 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 15 May 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 17 sites in United States, Spain, Belgium, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 15 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
