ClinicalTrials.gov Identifier:
NCT01011972
First Posted: November 11, 2009
Last Update Posted: September 20, 2016
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Mersana Therapeutics
  Purpose
XMT-1107 has been shown in nonclinical studies to slow the growth of tumors. These effects may result from blocking the growth of new blood vessels that help the tumors survive.

Condition Intervention Phase
Neoplasm Metastasis Drug: XMT-1107 Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Study of the Safety and Pharmacokinetics of XMT-1107 Administered as an Intravenous Infusion Once Every Three Weeks to Patients With Advanced Solid Tumors

Further study details as provided by Mersana Therapeutics:

Primary Outcome Measures:
  • The primary objective of this study is to determine the maximum tolerated dose of XMT-1107 when given via IV once every three weeks. [ Time Frame: Adverse events are assessed during each treatment cycle. ]

Secondary Outcome Measures:
  • Assess the pharmacokinetics (PK) of XMT-1107 and its release product [ Time Frame: Samples for PK are collected during Cycle 1 and prior to each subsequent treatment cycle ]
  • Determine the recommended Phase 2 dose of XMT-1107 [ Time Frame: Throughout Cycle 1 ]
  • Assess the safety of XMT-1107. [ Time Frame: Throughout Cycle 1 ]
  • Observe for evidence of anti-tumor activity by XMT-1107. [ Time Frame: Course of study ]
  • Monitor the effect of XMT-1107 on MetAP2 inhibition in leukocytes from patients [ Time Frame: Cycle 1 and Cycle 2 ]

Enrollment: 52
Study Start Date: March 2010
Study Completion Date: September 2013
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: XMT-1107
Dose escalation groups of XMT-1107, I.V. (in the arm) beginning at 6 mg/m^2, doubling in dose to 24 mg/m^2, then 40 mg/m^2, then 60 mg/m^2, then 80 mg/m^2 with subsequent doses at 33% of the previous until disease progression or unacceptable side effects are experienced.
Drug: XMT-1107
6 mg XMT-1107 administered by I.V. (in the vein) administered over 90 min, once every 21 days : until progression or unacceptable toxicity develops
Other Name: conjugated XMT-1191

Detailed Description:
This is an open-label, ascending-dose study of XMT-1107 administered intravenously over 90 minutes every 21 days (1 cycle). Blood sampling for PK analyses will be performed immediately prior to dosing and after dosing. Adverse events will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria (CTC) version 4.0 (CTCAE v4.0)

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient must have a histological diagnosis of advanced solid tumor and must be refractory to standard therapy or have no effective therapy.

    • Absolute neutrophil count (ANC) ≥ 1500 cells/mm3
    • Platelet count ≥ 100,000 cells/mm3
    • Hemoglobin ≥ 9 g/dL
    • Serum creatinine ≤ 1.5 mg/dL or calculated creatinine clearance ≥ 60 mL/min (Calculated by Cockroft and Gault method. Creatinine clearance (mL/min) = (140-age) x weight (kg)/72 x (serum creatinine in mg/dL) = ml**/min (**for females, multiply results by 0.85))
    • Total bilirubin ≤ 1.5 mg/dL or ≤ upper limit of normal (ULN)
    • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 times the institutional upper limit of normal (ULN) or ≤ 5 times ULN of liver metastases are present
    • Prothrombin time (PT) and partial thromboplastin time (PTT) ≤ 1.5 times the ULN
  • Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) 0-1.
  • Life expectancy of at least 3 months.
  • Signed informed written consent.

Exclusion Criteria:

  • Known brain metastases (either currently or previously).
  • Peripheral neuropathy ≥ Grade 2.
  • Ataxia ≥ Grade 1.
  • Cognitive disturbance ≥ Grade 1.
  • History of seizures.
  • Patients known to be human immunodeficiency virus (HIV) positive.
  • Active infections requiring IV antibiotics or serious intercurrent illness, including hepatitis B or C.
  • Unstable angina, recent myocardial infarction (within the previous 6 months), or use of ongoing maintenance therapy for life-threatening arrhythmia.
  • Known hypersensitivity to this class of drugs.
  • Pregnant or nursing women, women who are of childbearing potential and are not using an effective method of either barrier or hormonal contraceptives. Men who are not using an effective method of barrier contraceptive, or who would not be willing to continue to use these effective methods for the duration of the study.
  • Patients who have had a major surgical procedure (not including mediastinoscopy), open biopsy, or significant traumatic injury ≤ 4 weeks prior to beginning treatment.
  • Patients with proteinuria at screening as demonstrated by either:

    1. urine protein creatinine (UPC) ratio ≥ 1.0 at screening OR
    2. urine dipstick for proteinuria ≥ 2+ (patients discovered to have ≥ 2+ proteinuria on dipstick urinalysis at baseline should undergo a 24 hour urine collection, and must demonstrate ≤ 1 g of protein/24 hours to be eligible)
