Study summary

The main purpose of this study was to assess the antitumor activity of three combinations: i) LAG525 + spartalizumab; ii) LAG525 + spartalizumab + carboplatin, and iii) LAG525 + carboplatin in participants with advanced triple-negative breast cancer (TNBC) in first or second line therapy.

Read the detailed description

This was an open-label, Phase II, randomized, multicenter study to assess the efficacy, safety, and pharmacokinetic characteristics of the following three combinations: LAG525 + spartalizumab (PDR001) (Arm 1), LAG525 + spartalizumab (PDR001) + carboplatin (Arm 2), and LAG525 + carboplatin (Arm 3) in participants with advanced triple-negative breast cancer (TNBC) which progressed after adjuvant or one prior line of systemic therapy for metastatic disease.

Participants were assigned to one of the three treatment arms in a ratio of 1:1:1. In protocol amendment 3 (released on 28-Mar-2019), enrollment to treatment Arm 1 (LAG525 + spartalizumab) was prematurely closed due to a higher discontinuation rate due to progressive disease and all subsequent enrolled patients were randomized to Arms 2 and 3 only, in a ratio of 1:1.

Study treatment continued until disease progression, unacceptable toxicity, pregnancy, investigator/participant decision, start of a new anti-neoplastic therapy, withdrawal of consent, lost to follow-up, death, or study was terminated by the sponsor. The investigator might decide to stop carboplatin after 6 cycles, even if the above criteria were not met. Participants who continued to derive clinical benefit from the treatment based on the investigator's evaluation following their completion of this trial might receive post-trial access (PTA) i.e. rollover protocol or a post-study drug supply (PSDS).

The end of study was defined as the earliest occurrence of one of the following: (1) all participants had died or (2) discontinued from the study, or (3) another clinical study became available that could continue to provide study treatment in this participant population and all ongoing participants were eligible to be transferred to that clinical study.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumor measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumor visible on a scan does not by itself rule you out.

RECIST

The standard rules for measuring tumors on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumor 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumor. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

HER2

HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.

In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.

PD-1, PD-L1 and checkpoint inhibitors

PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.

PD-L1 can also be measured in a tumor sample. Some scores count stained tumor cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colors or preservatives.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

What researchers measure

Primary outcomes

  1. Overall Response Rate (ORR) Per Investigator's Assessment According to RECIST v1.1

    Overall response rate (ORR) is defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR) according to RECIST 1.1 based on investigator's assessment. The 95% CIs were computed using two-sided exact binomial method. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters.

    Time frame: Up to approximately 14 months

Secondary outcomes

  1. Clinical Benefit Rate (CBR) Per Investigator's Assessment According to RECIST v1.1

    CBR is defined as the percentage of participants with a best overall response (BOR) of confirmed CR or PR, or stable disease (SD) lasting 24 weeks or longer, according to RECIST 1.1 criteria. The 95% CI were computed using two-sided exact binomial method. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. SD: Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease.

    Time frame: Up to approximately 14 months

  2. Duration of Response (DOR) Per Investigator's Assessment According to RECIST v1.1

    DOR is the time between the first documented response (CR or PR) and the first documented progression or death due to underlying cancer based on RECIST1.1 and as per investigator's assessment. The DOR distribution was estimated using the Kaplan-Meier method and the 95% confidence intervals using the method of Brookmeyer and Crowley. If progression or death did not occur, the participant was censored at the date of last adequate tumor assessment. CR: Disappearance of all non-nodal target lesions and any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. Progression: at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. The sum must also demonstrate an absolute increase of at least 5 mm.

    Time frame: From first documented response up to disease progression or death due to underlying cancer, whichever occurs first, up to approximately 14 months

  3. Time to Response (TTR) Per Investigator's Assessment According to RECIST v1.1

    TTR is the time from date of randomization to first documented response of CR or PR based on investigators' assessment and according to RECIST 1.1. Median TTR was summarized using descriptive statistics. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters.

    Time frame: From date of randomization to first documented response (CR or PR), up to approximately 14 months

  4. Progression Free Survival (PFS)

    PFS is defined as time from date of randomization to the date of first documented progression or death due to any cause. PFS was assessed via investigator's assessment according to RECIST 1.1. PFS was censored at the date of the last adequate tumor assessment if no PFS event was observed prior to the analysis cut-off date or before the start of the new anticancer therapy date, whichever is earlier. The PFS distribution was estimated using the Kaplan-Meier method. The 95% confidence intervals were calculated using the method of Brookmeyer and Crowley.

    Time frame: From date of randomization to disease progression or death due to any cause, whichever occurs first, up to approximately 14 months

  5. Overall Survival (OS)

    OS is defined as the time from date of randomization to date of death due to any cause. If a participant was not known to have died, then OS was censored at the latest date the participant was known to be alive (on or before the cut-off date). The OS distribution was estimated using the Kaplan-Meier method. The 95% confidence intervals were calculated using the method of Brookmeyer and Crowley

    Time frame: From date of randomization to date of death due to any cause, up to 18 months

Outcome measures

PrimaryOverall Response Rate (ORR) Per Investigator's Assessment According to RECIST v1.1

Overall response rate (ORR) is defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR) according to RECIST 1.1 based on investigator's assessment. The 95% CIs were computed using two-sided exact binomial method. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters.

Time frame:
Up to approximately 14 months

SecondaryClinical Benefit Rate (CBR) Per Investigator's Assessment According to RECIST v1.1

CBR is defined as the percentage of participants with a best overall response (BOR) of confirmed CR or PR, or stable disease (SD) lasting 24 weeks or longer, according to RECIST 1.1 criteria. The 95% CI were computed using two-sided exact binomial method. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. SD: Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease.

SecondaryDuration of Response (DOR) Per Investigator's Assessment According to RECIST v1.1

DOR is the time between the first documented response (CR or PR) and the first documented progression or death due to underlying cancer based on RECIST1.1 and as per investigator's assessment. The DOR distribution was estimated using the Kaplan-Meier method and the 95% confidence intervals using the method of Brookmeyer and Crowley. If progression or death did not occur, the participant was censored at the date of last adequate tumor assessment. CR: Disappearance of all non-nodal target lesions and any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. Progression: at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. The sum must also demonstrate an absolute increase of at least 5 mm.

SecondaryTime to Response (TTR) Per Investigator's Assessment According to RECIST v1.1

TTR is the time from date of randomization to first documented response of CR or PR based on investigators' assessment and according to RECIST 1.1. Median TTR was summarized using descriptive statistics. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters.

SecondaryProgression Free Survival (PFS)

PFS is defined as time from date of randomization to the date of first documented progression or death due to any cause. PFS was assessed via investigator's assessment according to RECIST 1.1. PFS was censored at the date of the last adequate tumor assessment if no PFS event was observed prior to the analysis cut-off date or before the start of the new anticancer therapy date, whichever is earlier. The PFS distribution was estimated using the Kaplan-Meier method. The 95% confidence intervals were calculated using the method of Brookmeyer and Crowley.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2018 to primary completion in Feb 2020, 19 months.

Results were first posted in May 2022, 2 years 2 months after primary completion. A results delay was requested in Apr 2020.

Of 255 phase 2 interventional studies under Triple Negative Breast Neoplasms, half reached primary completion within 59 months of starting (the median), counting those still running; a quarter within 37 and three quarters within 94. This study's 19 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 30, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
