Phase I Intratumoral Pbi-shRNA STMN1 LP in Advanced and/or Metastatic Cancer (STMN1-LP)

February 16, 2018 updated by: Gradalis, Inc.

Phase I Trial of Intratumoral Bi-functional shRNA Stathmin 1-knockdown Lipoplex in Patients With Advanced and/or Metastatic Cancer

This is a Phase I safety trial of bifunctional shRNA-STMN1 (pbi-shRNA™STMN1) BIV (bilamellar invaginated vesicle) lipoplex (LP), pbi-shRNA™ STMN1 LP administered by a single intratumoral (IT) injection. Patients with superficially accessible advanced cancer following prior therapies will be entered into the study following a modified dose escalation design based on the demonstrated safety of our previous clinical experience (BB-IND 13744) with the same liposome and vector DNA backbone expressing a different transgene (of which doses up to 7 mg DNA IV/single dose have been administered). Patients will accrue in 4-patient escalation cohorts using a modified Fibronacci escalation schema (100%-50%-33%-33%) at a starting intratumoral dose of 0.010 mg/kg of DNA through a dose of 0.053 mg/kg DNA intratumoral / single dose. Should a single, but not more than two (2), ≥ Grade 3 Dose Limiting Toxicity (DLT) occur in any cohort, following mandated review (see below) an additional two (2) patients will be accrued at that dose (total of six). If more than one ≥ Grade 3 toxicity occurs in any cohort, the preceding dose cohort will be expanded to six (from four) and if < 2/6 patients experience ≥ Grade 3 toxicity, that dose will be the Phase II recommended dose. Should no ≥ Grade 3 toxicity occur in any cohort (other than Grade 3 local injection site reaction), an additional two (2) patients will be treated at 0.053 mg/kg DNA intratumoral / single dose.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)
