What is being measured

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

  1. Number of Participants Experiencing Dose Limiting Toxicities (DLTs)

    A DLT was a toxicity, considered possibly related to alobresib, and which occurred during DLT assessment window (Day 1 through Cycle 1 Day 28) in each cohort: Grade ≥ 4 neutropenia (absolute neutrophil count [ANC] < 500/mm^3); Grade ≥3 neutropenia (ANC< 1000/mm^3) with fever (a single temperature of > 38.3°C or a sustained temperature of ≥ 38°C for more than 1 hour [hr]); Grade ≥ 3 thrombocytopenia; Grade ≥ 2 bleeding; Grade ≥ 3 non hematologic toxicity, except Grade 3 nausea or emesis with maximum duration of 48 hrs on adequate medical therapy and Grade 3 diarrhea which persists for < 72 hrs in absence of maximal medical therapy; Grade ≥ 2 non hematologic treatment-emergent adverse event (TEAE) of potential clinical significance; treatment interruption ≥ 7 days due to unresolved toxicity; and any Grade 3 or 4 elevation in aspartate aminotransferase (AST) or alanine aminotransferase (ALT) associated with a Grade 2 elevation in bilirubin that is at least possibly related to alobresib.

    Measured: Baseline (Day 1) up to 28 days

Secondary outcomes (6)
  1. Pharmacokinetic (PK) Parameter: Cmax of Alobresib

    Cmax is defined as the maximum concentration of the drug.

    Measured: Cycle 1: Predose (0 hr), 0.5, 1, 2, 3, 4, 6, 8, 12 and 24 hrs postdose on Days 1 and 8 (1 Cycle = 28 days)

  2. PK Parameter: Ctau of Alobresib

    Ctau is defined as the observed drug concentration at the end of the dosing interval.

    Measured: Cycle 1: Predose (0 hr), 0.5, 1, 2, 3, 4, 6, 8, 12, and 24 hrs postdose on Day 8 (1 Cycle = 28 days)

  3. PK Parameter: AUC0-24 of Alobresib

    AUC0-24 is defined as the concentration of drug over time from time zero to time 24 hrs.

    Measured: Cycle 1: Predose (0 hr), 0.5, 1, 2, 3, 4, 6, 8, 12, and 24 hrs postdose on Days 1 and 8 (1 Cycle = 28 days)

  4. PK Parameter: AUCtau of Alobresib

    AUCtau is defined as the concentration of drug over time (the area under the concentration verses time curve over the dosing interval).

    Measured: Cycle 1: Predose (0 hr), 0.5, 1, 2, 3, 4, 6, 8, 12, and 24 hrs postdose on Day 8 (1 Cycle = 28 days)

  5. PK Parameter: Tmax of Alobresib

    Tmax is defined as the time (observed time point) of Cmax.

    Measured: Cycle 1: Predose (0 hr), 0.5, 1, 2, 3, 4, 6, 8, 12, and 24 hrs postdose on Days 1 and 8 (1 Cycle = 28 days)

  6. PK Parameter: t1/2 of Alobresib

    t1/2 is defined as the estimate of the terminal elimination half-life of the drug. Due to short sampling period of the terminal elimination phase in these cohorts t1/2 values should be interpreted with caution.

    Measured: Cycle 1: Predose (0 hr), 0.5, 1, 2, 3, 4, 6, 8, 12, and 24 hrs postdose on Days 1 and 8 (1 Cycle = 28 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Alobresib, Exemestane and Fulvestrant in people with Solid Tumors and Lymphomas, run by Gilead Sciences at 4 sites in United States.

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 9 inclusion and 10 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 29 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 29 Dec 2020). 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?

Number of Participants Experiencing Dose Limiting Toxicities (DLTs) (time frame: Baseline (Day 1) up to 28 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Dec 2020.
