HOW TO USE THIS SNAPSHOT The information provided in Snapshots highlights who participated in the clinical trials that supported the FDA approval of this drug, and whether there were differences among sex, race and age groups. The “MORE INFO” bar shows more detailed, technical content for each section. The Snapshot is intended as one tool for consumers to use when discussing the risks and benefits of the drugs.
LIMITATIONS OF THIS SNAPSHOT: Do not rely on Snapshots to make decisions regarding medical care. Always speak to your health provider about the risks and benefits of a drug. Refer to the LORBRENA Package Insert for complete information.
LORBRENA (lorlatinib) lor-BREN-ah Pfizer Labs Approval date: November 2, 2018
DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
LORBRENA is a drug used to treat patients with a type of non-small cell lung cancer (NSCLC) that
is caused by an abnormal anaplastic lymphoma kinase (ALK) gene and,
has spread to other parts of your body (metastatic) and,
has progressed while on one or more anti-cancer drugs approved for treatment of ALK-positive lung cancer.
How is this drug used?
LORBRENA is a tablet taken by mouth once a day.
What are the benefits of this drug?
Overall, 48% of patients who had measurable cancer lesions prior to taking LORBRENA had a complete or partial shrinkage of the lesions which lasted an average of 12.5 months. Approximately 60% of patients who had measurable cancer lesions in the brain prior to taking LORBRENA had a complete or partial shrinkage of the lesions in the brain which lasted an average of 19 months.
LORBRENA was approved under FDA’s accelerated approval program, which provides earlier patient access to a promising new drug while the company continues to conduct clinical trials to confirm that the drug works well.
LORBRENA may cause serious side effects including high levels of fat in the blood, complete or partial block of the signal that controls the heartbeat, life-threatening inflammation of the lungs, and side effects affecting the brain, including seizures, hallucinations, changes in mood (including suicidal ideation), speech, mental status, and sleep.
The most common side effects of LORBRENA are swelling of the feet and legs (edema), weakness, numbness and pain from nerve damage, changes in memory, judgement or reasoning, difficulty breathing, tiredness, weight gain due to retaining water, joint pain, mood changes, and diarrhea.
The FDA approved LORBRENA based on evidence from one clinical trial (Trial 1/NCT01970865) of 295 patients with metastatic NSCLC. Patients were previously treated with anti-cancer drugs, but their disease has progressed despite that treatment. The trial was conducted at 47 sites in Asia, Australia, Canada, Europe, and the United States.
Demographics of the 215 patients who provided data for evaluation of benefits of LORBRENA (efficacy population) are presented in Table 10, under the MORE INFO section.
Demographics of the 295 patients who provided data for side effects of LORBRENA (safety population) is presented below.
Figure 1 summarizes how many men and women were in the clinical trial used to evaluate safety.

The figure below summarizes the percentage of patients by age group in the clinical trial used to evaluate safety.
The benefits and side effects of LORBRENA were evaluated in one clinical trial.
Patients had metastatic, non-small cell lung cancer (NSCLC) and at least one measurable cancer lesion. The cancer had progressed while on anti-cancer drugs that treat ALK-positive lung cancers. The benefit of LORBRENA was assessed by measuring if and how much the cancer lesions decreased in size during treatment and how long that tumor shrinkage lasted.
CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments. COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested. EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial. PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo. SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
