    TST labeled with 185 megaBecqueral (mbq) of iodine 131

Study groups in NCT00240565
Study groupRoleWhat they receive
Arm 1ExperimentalParticipants underwent two phases of treatment: an initial DD, followed by a therapeutic dose. The one-day DD comprised a 1 hr IV infusion of 450 mg unlabeled TST, followed by a 20 min IV infusion of 35 mg TST labeled with 185 MBq (5.0 mCi) of I 131. After 7 to 14 days, the one-day therapeutic dose comprised a second 1 hr IV infusion of 450 mg unlabeled TST, followed by a 20 min IV infusion of 35 mg TST labeled with I 131 with an administered activity (MBq or mCi) determined from the dosimetry calculation.
Receives: Drug: Tositumomab 450 mg; Drug: Tositumomab 35 mg

What is being measured

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

  1. Response Rate

    Responders are defined as participants with Complete Response (CR: disappearance of all clinical and radiological evidence of lymphoma), Clinical Complete Response (CCR: all criteria met for CR, except there is a residual nodal mass >15 millimeters), or Partial Response (PR: 50% reduction in the sum of the products of the longest perpendicular diameters of all measurable lesions with no new lesions). Response is based on objective evaluation, using the guidelines developed by The International Workshop to Standardize Response Criteria, independent of the investigator's evaluation.

    Measured: Week 26

Secondary outcomes (7)
  1. Complete response rate (CR)

    Investigator-assessed confirmed CR is defined as the disappearance of all clinical and radiological evidence of lymphoma. Response is based on objective evaluation, using the guidelines developed by The International Workshop to Standardize Response Criteria, independent of the investigator's evaluation.

    Measured: From the start of treatment (Study Day 0, Baseline) until long-term follow-up (every 6 months until 5 years from the time of study entry)

  2. Duration of response

    Duration of response is defined as the time from the first documented response to the first documented disease progression. Response is based on objective evaluation, using the guidelines developed by The International Workshop to Standardize Response Criteria, independent of the investigator's evaluation. Disease progression is defined as a 50% increase in the sum of the products of the two perpendicular diameters of all measurable lesions, or the appearance of new lesions.

    Measured: 5 years

  3. Progression-free survival (PFS)

    PFS is defined as the time interval between the date of the DD to the first date at which progressive disease (PD) or death is observed. PD is defined as a 50% increase in the sum of the products of two perpendicular diameters of all measurable lesions, or the appearance of new lesions. Participants with no evidence of PD were censored to the last date of contact; and those who died for any reason in the absense of PD were classified as having experienced PD on the date of death. For non-responders, duration of PFS was recorded as 0. Participants were censored if they withdrew without PD.

    Measured: 5 years or until death

  4. Adverse events

    An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. A serious adverse event (SAE) is any untoward medical occurrence that, at any dose results in death; is life-threatening; requires hospitalization or prolongation of existing hospitalization; results in disability/incapacity; is a congenital anomaly in a child from a parent who was exposed to treatment; or is an SAE based on medical or scientific judgement of the investigator.

    Measured: 5 years or until death

  5. Quality of Life

    Qualty of Life will be asessed utilizing several scales and questionnaires: FACT-G questionnaire was designed to measure multidimensional quality of life (QOL) in participants with cancer. FACT-LymThe FACT-Lym subscale questionnaire is a cancer-specific questionnaire designed to measure multidimensional QOL in participants with lymphoma.

    Measured: 5 Years

  6. Resource Utilization Assessment

    The Resource Utilization Assessment questionnaires are used to assess the resource utilization of the participant and impacted associates (e.g., family members, caregivers) as well as costs involved to treat participants receiving TST and I 131 TST. As an assessment of general health, participants were asked to rate their activity level on average in the last 7 days on an 11-point scale: 0= exhausted in bed all day; 10=normal activity level.

    Measured: Week 26

  7. Duration of Overall Survival

    Survival time is defined as the number of weeks from the first study medication administration to the date of death. In the absence of confirmation of death, survival time was censored to the last date the participant was known be alive. If the participant was alive at the time of analysis, then the survival time was censored at the date of last contact.

    Measured: 5 years or until death

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tositumomab 450 mg and Tositumomab 35 mg in people with Lymphoma, Non-Hodgkin, run by GlaxoSmithKline at 11 sites in Canada.

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 3 inclusion and 8 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 Aug 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Canada. 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Response Rate (time frame: Week 26). 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 NCT00240565, 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 13 Aug 2012.
