About this study

Official title: A Phase I/II Trial of Ketoconazole, Hydrocortisone, Dutasteride and Lapatinib (KHAD-L) in Castration Resistant Prostate Cancer With Pre- and Post-therapy Tumor Biopsies

The purpose of this research study is to determine the safety of giving ketoconazole, hydrocortisone and dutasteride (KHAD) with lapatinib. Safety is primarily based on dose limiting toxicity (DLT) evaluation at various dose levels (DL). The investigators believe that there is evidence in castrate resistant prostate cancer (CRPC) that two growth factor receptors (EGFR and Her 2/Neu) are increased in prostate cancer (PCa) cells. Both these receptors are turned off by the drug lapatinib. By adding lapatinib, the investigators hope that signaling from the receptors will be turned off and therefore make the participant's cancer more responsive to KHAD treatment.

Read the detailed description

The current study builds on investigators' KHAD experience by further targeting pathways that may still be enhancing AR activity despite reduced testosterone and DHT. Importantly, studies from several groups have shown that EGFR and Her2/Neu activation can enhance AR signaling and increase AR transcriptional activity in response to low levels of androgens. Evaluation in the clinic and lab has shown that there is increased expression of EGFR or Her2/Neu in CRPC. In addition to upregulation in EGFR and Her2/Neu protein expression, signaling through these receptors may be enhanced in some tumors by increases in growth factor levels or other mechanisms. Based on these results, the investigators suggest that EGFR and Her2/Neu contribute to enhancing AR transcriptional activity especially at low androgen levels. If this hypothesis is correct, then dual blockade of EGFR and Her2/Neu in CRPC should enhance the ability of KHAD to abrogate AR activity. Moreover, as androgens can protect PCa cells from cell death in response to EGFR/Her2/Neu/PI3 kinase pathway inhibition, we propose that KHAD plus lapatinib may be a particularly active combination therapy for CRPC.

What is being measured

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

  1. Lapatinib Maximum Tolerated Dose (MTD) [Phase I]

    The MTD of lapatinib in combination with KHAD is determined by the number of participants who experience a dose limiting toxicity (DLT) at the various dose levels of lapatinib under evaluation. See subsequent primary outcome measure for the DLT definition. The MTD is defined as the lapatinib dose at which fewer than one-third of patients experience a DLT. If no DLTs are observed, the MTD is not reached and the Recommended Phase II Dose (RP2D) will be based on safety and pharmacokinetic results.

    Measured: The evaluation for MTD occurred continuously through one cycle of KHLAD treatment (28 days).

  2. Lapatinib Dose Limiting Toxicity (DLT) [Phase I]

    A DLT is defined as an adverse event (AE) occurring during the first cycle of KHLAD treatment that are determined to related to the Lapatinib or the combination as follows:

    1. Any Grade 3 or greater non-hematological treatment related (possible, probable, or definite attribution) including diarrhea
    2. Grade 4 or greater for hematological toxicities, regardless of attribution.
    3. Grade 3 skin reactions, pulmonary reactions, regardless of attribution.

    Measured: The evaluation for DLT occurred continuously through one cycle of treatment (28 days).

  3. Plasma Lapatinib Levels [Phase I]

    Plasma lapatinib levels were measured after day 28 of KHLAD treatment. Participants were instructed to fast prior to samples being taken.

    Measured: After first 28 days of KHLAD treatment

Secondary outcomes (1)
  1. Grade 3-4 Treatment-Related Adverse Events Rate

    All grade 3-4 adverse events (AE) with treatment attribution of possibly, probably or definite based on CTCAEv4 as reported on case report forms were counted to calculate the proportion of participants experiencing at least one treatment-related grade 3 or 4 AE of any type on treatment.

    Measured: Assessed each cycle throughout treatment. Treatment duration in months was a median (range) of 5.4 months (range 1 day-8.3 months). Thus, AEs were evaluated up to 8.3 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ketoconazole, hydrocortisone and dutasteride in people with Prostate Cancer, run by Dana-Farber Cancer Institute at 2 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 16 inclusion and 18 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: stopped early, as of the sponsor's last update on 4 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 4 Sep 2018). 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?

Lapatinib Maximum Tolerated Dose (MTD) [Phase I] (time frame: The evaluation for MTD occurred continuously through one cycle of KHLAD treatment (28 days).). The study lists 3 primary outcomes in all. 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 4 Sep 2018.
