Safety and Efficacy Study of DCVax-Direct in Solid Tumors

This study is ongoing, but not recruiting participants.
Information provided by (Responsible Party):
Northwest Biotherapeutics Identifier:
First received: June 14, 2013
Last updated: October 6, 2015

The study comprises a Phase I component during which the optimal dose of DCVax-Direct for the treatment of solid tissue tumors will be identified, followed by a Phase II component to determine if the injection of DCVax-Direct into selected solid tissue tumors has the ability to reduce tumor growth.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria (summary):

  • Age between 18 and 75 years (inclusive) at screening.
  • Karnofsky performance status (KPS) of 70 or higher or Eastern Cooperative Oncology Group (ECOG) 0-1 at screening.
  • Subjects with a histological or cytopathological confirmed diagnosis of a locally advanced or metastatic solid tumor malignancy for which primary treatment is no longer effective or does not offer curative or life-prolonging potential per clinician judgment, with the understanding that DCVax-Direct is not intended as a treatment of last resort.
  • Not eligible for complete resection due to either tumor location, physician's assessment or subject's choice.
  • Must have completed at least one recent treatment regimen in the metastatic or advanced setting in the disease currently under treatment to reduce tumor burden.
  • Any steroid therapy >2 mg dexamethasone or equivalent dose should be stopped or have been tapered down 2 weeks prior to the leukapheresis.
  • At least one measurable tumor mass, i.e. a lesion that can accurately be measured by CT/MRI in at least one dimension with longest diameter ≥ 1 cm, that is accessible for injection either with or without imaging (CT/ultrasound) guidance.
  • Adequate hematological, hepatic, and renal function,
  • Adequate blood coagulation parameters
  • Life expectation of >3 months.

Exclusion Criteria (Summary):

  • Positive HIV-1, HIV-2, or Human T-lymphotropic virus (HTLV-I/II) tests.
  • History of current or prior (within the last two years) active clinically significant malignancy other than the tumor type for which DCVax-Direct treatment is considered, and except for primary tumor in the case of metastases and adequately treated basal cell or squamous cell skin cancer or in situ cervical cancer.
  • Heavily pretreated (HP) subjects are not eligible for this study, unless treatments have occurred more than 1 year in the past.
  • Presence of brain metastases, unless treated surgically and/or irradiated and clinically stable off steroids or on low dose (< 2 mg per day) steroids for ≥ 14 days, or presence of leptomeningeal disease.
  • History of immunodeficiency or unresolved autoimmune disease.
  • Requirement for ongoing immunosuppressants.
  • Prior active immunotherapy for cancer within the past 2 years.
  • Ongoing medical need for continuous anti-coagulation or anti-platelet medication.
  • Known genetic cancer-susceptibility syndromes.
  • Acute or active uncontrolled infection
  • Ongoing fever ≥ 101.5 degrees F/38.6 degrees C at screening.
  • Unstable or severe intercurrent medical conditions such as unstable angina, uncontrolled arrhythmias, Crohn's Disease, ulcerative colitis etc.
  • Females of child-bearing potential who are pregnant or lactating or who are not using adequate contraception (surgical, hormonal or double barrier, i.e. condom and diaphragm).
  • Allergy or anaphylaxis to any of the reagents used in this study.
  • Inability to obtain informed consent because of psychiatric or complicating medical problems.
  • Inability or unwillingness to return for required visits and follow-up exams.
