What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to Reach Maximum Observed Plasma Concentration (Tmax) at Steady-State for Both Total and Unbound GDC-0449

    Measured: Predose and 1, 2, 4, 6, 24, 48, and 72 on Days 1, 29, 50, and 54 and predose on Days 8, 10, 15, 22, 33, 36, 43, and 57

  2. Number of Participants With Greater Than (>) 50 Percent (%) Decrease in Trough Concentration at Steady State (Css, Trough)

    Percent change = ([trough concentration on Day 15 minus trough concentration on Day 57] divided by trough concentration on Day 15) multiplied by 100.

    Measured: Predose and 1, 2, 4, 6, 24, 48, and 72 on Days 1, 29, 50, and 54 and predose on Days 8, 10, 15, 22, 33, 36, 43, and 57

  3. Ratio of Total and Unbound Trough GDC-0449 Concentration Between Day 57 to Day 15

    Ratio = trough concentration on Day 57 divided by trough concentration on Day 15. If the ratio of total and unbound trough GDC-0449 concentration between Day 57 to Day 15 is less than 1, then it indicates reduction in total and unbound trough GDC-0449 concentration between Day 15 to Day 57.

    Measured: Predose and 1, 2, 4, 6, 24, 48, and 72 on Days 1, 29, 50, and 54 and predose on Days 8, 10, 15, 22, 33, 36, 43, and 57

  4. Plasma Concentration at Steady State (Css) for Total and Unbound GDC-0449

    Plasma GDC-0449 concentrations were reported in nanogram per milliliter (ng/mL) units and converted to micromolar (mcM) units using the molecular weight (421.30 grams per mole [g/mol]) prior to PK analysis. Css was calculated for Days 28 to 56.

    Measured: Predose and 1, 2, 4, 6, 24, 48, and 72 on Days 1, 29, 50, and 54 and predose on Days 8, 10, 15, 22, 33, 36, 43, and 57

  5. Maximum Plasma Concentration (Cmax) of Total and Unbound GDC-0449

    Plasma GDC-0449 concentrations were reported in ng/mL units and converted to mcM units using the molecular weight (421.30 g/mol) prior to PK analysis.

    Measured: 0, 1, 2, 4, 6, 24, 48, 72 hours on Day 1, 15 and 57 post-dose

  6. Area Under the Curve From Time Zero to 24 Hour (AUC0-24) for Total and Unbound GDC-0449

    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption. AUC values were calculated using the linear trapezoidal method when the concentrations were rising and using the logarithmic trapezoidal method when the concentrations were declining (linear up/log down rule in WinNonlin). Below the limit of quantitation (BLQ) values at pre-dose were considered as zero for PK analysis.

    Measured: Predose and 1, 2, 4, 6, 24, 48, and 72 on Days 1, 29, 50, and 54 and predose on Days 8, 10, 15, 22, 33, 36, 43, and 57

  7. Area Under the Curve From Time Zero to the Last Measured Concentration (AUClast) for Total and Unbound GDC-0449

    AUC values were calculated using the linear trapezoidal method when the concentrations were rising and using the logarithmic trapezoidal method when the concentrations were declining (linear up/log down rule in WinNonlin). BLQ values at pre-dose were considered as zero for PK analysis.

    Measured: Predose and 1, 2, 4, 6, 24, 48, and 72 on Days 1, 29, 50, and 54 and predose on Days 8, 10, 15, 22, 33, 36, 43, and 57

  8. Time to Achieve Maximum Observed Plasma Concentration (Tmax) After a Single Dose of GDC-0449

    Measured: 0, 1, 2, 4, 6, 24, 48, 72 hours on Day 1

Secondary outcomes (4)
  1. Percentage of Participants With Disease Progression or Death

    Disease progression (assessed by Response Evaluation Criteria in Solid Tumors [RECIST]) was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of one or more new lesions or the appearance of one or more new lesions and/or unequivocal progression of existing non target lesions.

    Measured: Screening, Day 57, and every 8 weeks thereafter up to 52 weeks

  2. Percentage of Participants With a Response by Best Overall Response (BOR)

    BOR was defined as the best overall response observed during the treatment period according to RECIST. CR: disappearance of all TLs, with any pathological lymph nodes (whether target or non-target) having a reduction in short axis to less than 10 mm. PR: at least a 30% decrease in the sum of diameters of TLs, taking as reference the BL sum diameters. Progressive disease (PD): at least a 20% increase in the sum of diameters of TLs, taking as a reference the smallest sum on study (this included the baseline sum if that is the smallest on study). In addition to the relative increase in 20%, the sum must also have demonstrated an absolute increase of at least 5 mm. Stable disease (SD) was defined as neither sufficient shrinkages to qualify for PR, nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

    Measured: Screening Day 57, and every 8 weeks thereafter up to 52 weeks

  3. Progression-Free Survival (PFS) Time

    PFS defined as the time from study treatment initiation to the first occurrence of disease progression, as determined by the investigator review of tumor assessments using RECIST, or death from any cause during the study (i.e., within 30 days after the last dose of study treatment).

    Measured: Screening Day 57, and every 8 weeks thereafter up to 52 weeks

  4. Duration of Response (DR)

    DR during first line therapy is defined as the time from when response (complete response [CR] or partial response [PR]) was first documented to first documented disease progression or death (whichever occurs first) during first line therapy. This was only be calculated for participants who achieved a best overall response of CR or PR. Participants who did not progress or die after they had a confirmed response were censored at the date of their last tumor measurement or last follow up for progression of disease during first line therapy. CR: disappearance of all target lesions (TLs) with any pathological lymph nodes (whether target or non-target) having a reduction in short axis to less than 10 millimeters. PR: at least a 30% decrease in the sum of diameters of TLs, with reference to baseline sum diameters. DR was not calculated as only 1 responding participant reached their response at the last scheduled response assessment, hence follow-up data are not available.

    Measured: Screening Day 57, and every 8 weeks thereafter up to 52 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GDC-0449 in people with Solid Cancers, run by Genentech, Inc..

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 8 inclusion and 7 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: finished, as of the sponsor's last update on 11 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 9 Dec 2015). 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to Reach Maximum Observed Plasma Concentration (Tmax) at Steady-State for Both Total and Unbound GDC-0449 (time frame: Predose and 1, 2, 4, 6, 24, 48, and 72 on Days 1, 29, 50, and 54 and predose on Days 8, 10, 15, 22, 33, 36, 43, and 57). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00968981, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jul 2017.
