This is an open-label, multicenter, Phase I dose-escalation study to assess the safety, tolerability, and pharmacokinetics of GDC-0623 in patients with locally advanced or metastatic solid tumors. Patients will be enrolled in one of two stages: a dose-escalation stage (Stage I) followed by an expansion stage (Stage II). Stage I will evaluate the safety, tolerability, and pharmacokinetics of increasing doses of GDC-0623 administered orally on a 21 day on/7-day off dosing schedule.

Condition Intervention Phase
Solid Cancers
Drug: GDC-0623
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open-label, Phase I, Dose Escalation Study Evaluating the Safety, Tolerability and Pharmacokinetics of GDC-0623 Administered Daily in Patients With Locally Advanced or Metastatic Solid Tumors

Further study details as provided by Genentech, Inc.:

Primary Outcome Measures:
  • Incidence and nature of dose-limiting toxicities (DLTs) [ Time Frame: Through study completion or early discontinuation ]
  • Incidence, nature, and severity of adverse events and serious adverse events, graded according to NCI CTCAE, v4.0 [ Time Frame: Through study completion or early discontinuation ]
  • Pharmacokinetic parameters of GDC-0623 (total exposure, maximum and minimum plasma concentrations, time to maximum plasma concentration, elimination half-life) [ Time Frame: Through study completion or early discontinuation ]

Secondary Outcome Measures:
  • Objective response for patients with measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Through study completion or early discontinuation ]
  • Duration of objective response for patients with measurable disease according to RECIST [ Time Frame: Through study completion or early discontinuation ]
  • Progression-free survival (PFS) for patients with measurable disease according to RECIST [ Time Frame: Through study completion or early discontinuation ]

Enrollment: 61
Study Start Date: April 2010
Study Completion Date: August 2014
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A Drug: GDC-0623
Repeating oral dose


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

Inclusion Criteria:

  • Histologically or cytologically documented, locally advanced or metastatic solid tumors for which standard therapy either does not exist or has proven ineffective or intolerable
  • Evaluable disease or disease measurable per RECIST
  • Life expectancy >= 12 weeks
  • Adequate hematologic and end organ function
  • Agreement to use effective form of contraception for the duration of the study
  • Consent to provide archival tissue
  • For the cohort expansion stage (Stage II): Patients in this cohort must have had no more than four prior systemic therapies for cancer and must have KRAS mutant CRC (Stage II A and B), pancreatic cancer (Stage IIC, or KRAS mutant NSCLC [Stage IID])

Exclusion Criteria:

  • History of prior significant toxicity from a MEK pathway inhibitor requiring discontinuation of treatment
  • History of parathyroid disorder or history of malignancy-associated hypercalcemia requiring therapy in the last 6 months
  • History of retinal vein occlusion (RVO) or predisposing factors to RVO, including uncontrolled hypertension, uncontrolled diabetes, uncontrolled hyperlipidemia, and coagulopathy
  • Evidence of visible retinal pathology considered a risk factor for retinal vein thrombosis
  • History of glaucoma
  • Palliative radiotherapy, experimental therapy, or anti-cancer therapy or major surgical procedure within a specified timeframe prior to first dose of study drug
  • Current severe, uncontrolled systemic disease
  • History of clinically significant cardiac dysfunction
  • History of active gastrointestinal bleeding within 6 months prior to screening
  • Clinically significant history of liver disease, current alcohol abuse, or current known active infection with HIV, or hepatitis B or C virus
  • Active autoimmune disease
  • Uncontrolled ascites
  • Pregnancy, lactation, or breastfeeding
  • Known brain metastases that are untreated, symptomatic, or require therapy to control symptoms
  • For the Exploratory PK Cohorts (Stage IB and Stage IC): Patients who have a history of or ongoing gastro-esophageal reflux disease or peptic ulcer, or who have gastric pathology or history of gastric surgery which could affect absorption of GDC-0623 from the stomach, will be excluded from these cohorts
