Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subjects had pathologically confirmed NSCLC and currently have Stage IIIb or IV NSCLC
  • Subjects had failed treatment with erlotinib at 150 mg qd
  • Subjects had tolerated erlotinib at the dose of the cohort in which they were enrolled (or at a higher dose) for at least 6 weeks (or for the duration of treatment if disease progression had occurred during treatment with erlotinib for less than 6 weeks)
  • The subject was at least 18 years old
  • The subject had an ECOG performance status of < 2
  • The subject had organ and marrow function as follows: - absolute neutrophil count ≥ 1500/mm3, platelets ≥ 100,000/mm3, hemoglobin ≥ 9 g/dL, bilirubin ≤ 1.5 times the upper limit of normal, serum creatinine ≤ 1.5 mg/dL or if serum creatinine > 1.5 mg/dL calculated creatinine clearance ≥ 60 mL/min, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 times the upper limit of normal, amylase and lipase < 1.5 times the upper limit of normal

  • Female subjects of childbearing potential had to have a negative pregnancy test at enrollment. Females of childbearing potential were defined as sexually mature women without prior hysterectomy or who had evidence of menses in the past 12 months. However, women who had been amenorrheic for 12 or more months were still considered to be of childbearing potential if the amenorrhea was possibly due to prior chemotherapy, antiestrogens, or ovarian suppression

  • Subjects had: Documented radiological PD, following a prior response, per investigator assessment, to monotherapy with erlotinib, OR; Documented radiological PD, per investigator assessment, following stable disease of at least 6 months on monotherapy with erlotinib
  • Subjects who had received subsequent anti-cancer therapy after having progressed on erlotinib (as defined above) also had to have documented radiological PD per investigator assessment to their most recent anti-cancer therapy. If the most recent anti-cancer therapy was erlotinib after having previously progressed on erlotinib (as defined above) the subject also had to have documented radiological PD per investigator assessment to their most recent course of erlotinib
  • Subjects had to have tolerated erlotinib at the maximal dose that would be administered in Phase 2 (or at a higher dose) for a minimum of 6 weeks
  • Subjects had measurable disease per RECIST
  • Subjects had to have 15 unstained consecutive slides of archival or fresh tumor tissue (from one tumor block, frozen tumor tissue, or a paraffin block) identified and designated for shipment to the sponsor if permitted by local regulations (including IRB [Institutional Review Board] policies).

About this study

Official title: A Phase 1b/2 Study of XL184 With or Without Erlotinib in Subjects With Non-Small Cell Lung Cancer

The study consisted of a Phase 1 dose escalation/dose de-escalation portion to determine a safe and tolerable combination dose(s) of cabozantinib and erlotinib, and a Phase 2 Simon optimal 2-stage design portion with randomized assignment of subjects in an equal ratio to determine the objective response rate (ORR) of cabozantinib with or without erlotinib in subjects with non-small cell lung cancer (NSCLC) who have progressed after responding to treatment with erlotinib. The doses of cabozantinib used in this study were based on the salt weight, not the freebase weight.

What is being measured

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

  1. Phase 1: Duration of Exposure of Cabozantinib With Erlotinib

    Treatment duration was defined as the number of days from the first dose to the last dose (measured in weeks), including any days of treatment interruption that occurred before the last dose of study drug.

    Measured: From initial dose up to 160 weeks

  2. Phase 2: Objective Response Rate (ORR)

    Objective Response Rate is defined as the number of participants for whom the best overall response is complete (CR) or partial response (PR) confirmed by repeat assessments no less than four weeks after the criteria for the initial response were first met.

    Measured: From initial dose up to 72 weeks

Secondary outcomes (2)

  1. Phase 2: Duration of Response (DOR) in Participants With a CR or PR

    DOR was defined as the time interval from the first documentation of CR or PR to the earlier of the first documentation of definitive disease progression or death from any cause.

    Measured: From initial dose up to 72 weeks

  2. Phase 2: Progression-Free Survival (PFS)

    Progression-free survival is defined as the time from first dose of cabozantinib to disease progression per protocol-defined criteria or death due to any cause, whichever occurs first.

    Measured: From initial dose up to 72 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing XL184 and erlotinib in people with Carcinoma, Non-Small-Cell Lung, run by Exelixis at 13 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 21 inclusion and 21 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 13 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 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 13 Jan 2026). 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?

Phase 1: Duration of Exposure of Cabozantinib With Erlotinib (time frame: From initial dose up to 160 weeks). The study lists 2 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 NCT00596648.

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 13 Jan 2026.
