Relapse-Free Survival With Adjuvant Dabrafenib/Trametinib Therapy in Patients With BRAF V600-mutated Stage III/IV Melanoma

August 13, 2024 updated by: Novartis

Relapse-Free Survival With Adjuvant Dabrafenib/Trametinib Therapy After Relapse on Adjuvant Checkpoint Inhibitor Therapy and Subsequent Surgical Resection in Patients With BRAF V600-mutated Stage III/IV Melanoma

This was a retrospective chart review study of all proto-oncogene B-Raf (BRAF) V600-mutated patients who received adjuvant checkpoint inhibitor (CPI) therapy, relapsed locoregionally or distantly, and were again resected to no evidence of disease (NED) and treated with adjuvant dabrafenib and trametinib (dab/tram) combination therapy.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Sampling Method

Probability Sample

Study Population

This was a retrospective, noninterventional cohort study.

Description

Inclusion Criteria:

  • Any patient at least 18 years of age at the time of diagnosis of stage III/IV melanoma.
  • Received surgical resection with no residual disease following initial stage III/IV melanoma diagnosis.
  • Documented local or central assay-positive for tumor BRAF V600E/K mutation.
  • Received adjuvant CPI alone or in combination with any other immune treatment as their first adjuvant therapy.
  • Following adjuvant CPI, relapsed (locoregionally or distantly) on or off treatment and was again rendered free of disease after subsequent surgical resection.
  • Received additional adjuvant dab/tram combination therapy after failing adjuvant CPI and being subsequently resected to NED.

Exclusion Criteria:

  • Previous administration of any BRAF- or mitogen-activated protein kinase (MEK)-targeted therapies.
  • More than 120 days duration between surgery to render the patient NED after relapsing during or after adjuvant CPI therapy and initiation of dab/tram adjuvant therapy.
  • Administration of any intervening antitumor medical and/or radiation therapy between failing adjuvant CPI and initiation of adjuvant dab/tram.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Dabrafenib and Trametinib Combination Therapy Cohort
Adult BRAF V600 patients with resected stage III/IV melanoma that relapsed during or after CPI as their first adjuvant therapy and were again rendered free of disease and received adjuvant dab/tram combination therapy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Relapse-free Survival-2 (RFS-2)
Time Frame: Up to 63 months

RFS-2 was defined as the time from the study index date until the date of the earliest clinician-documented disease progression, death, or start of a new line of anticancer treatment due to disease progression. Patients without a progression event as described above were censored at the last available follow-up, defined as last known clinic visit or last known contact with the patient (if occurred outside the clinic setting).

Index date was defined as the date that dab/tram combination therapy was initiated after being rendered disease-free for a second time following additional resection after prior relapse on initial CPI adjuvant therapy.
Up to 63 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival (OS)
Time Frame: Up to 63 months

OS was defined as the time from the study index date until death due to any cause. Patients without a death event were censored at last available follow-up, defined as last known clinic visit or last known contact with the patient (if occurred outside the clinic setting).

Index date was defined as the date that dab/tram combination therapy was initiated after being rendered disease-free for a second time following additional resection after prior relapse on initial CPI adjuvant therapy.
Up to 63 months
Distant Metastases-free Survival (DMFS)
Time Frame: Up to 63 months

DMFS was defined as the time from the study index date until the first observation of disease progression with distant metastasis. Patients without a DMFS event as described above were censored at last available follow-up, defined as last known clinic visit or last known contact with the patient (if occurred outside the clinic setting).

Index date was defined as the date that dab/tram combination therapy was initiated after being rendered disease-free for a second time following additional resection after prior relapse on initial CPI adjuvant therapy.
Up to 63 months
Number of Patients with an Adverse Event (AE) Related to Dabrafenib and Trametinib Combination Therapy
Time Frame: Up to 63 months
Up to 63 months
Mean Number of Times an AE Related to Dabrafenib and Trametinib Combination Therapy was Experienced
Time Frame: Up to 63 months
Up to 63 months

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
