| Eligibility |
Inclusion Criteria:
- Histologically or cytologically confirmed diagnosis of metastatic NSCLC (Stage IV,
American Joint Committee on Cancer v7.0) that carries an ALK rearrangement, as
determined by the Food and Drug Administration (FDA)-approved FISH test, using Vysis®
ALK Break apart fluorescence in situ hybridization (FISH) Probe Kit (defined as 15% or
more positive tumor cells), or the Ventana® immunohistochemistry (IHC) test, or a ROS1
rearrangement as determined by FISH or reverse transcription polymerase chain reaction
(RT-PCR) or Next Generation Sequencing (NGS) via a local diagnostic test (LDT).
- ALK positive NSCLC patients must either be treatment naive in the advanced setting or
have had disease progression on or intolerance to at least 1 previous ALK inhibitor.
ROS1 positive NSCLC patients must either be treatment naive in the advanced setting or
have had disease progression on or intolerance to at least 1 previous ROS1 inhibitor.
- Presence of radiographically suspected leptomeningeal disease (LM) or carcinomatous
meningitis (CM) AND/OR presence of at least one CNS lesion for which the following
criteria are met:
- For patients without leptomeningeal disease: presence of at least one parenchymal
CNS lesion that is at least 5 mm in size. Note: Intra-cranial disease assessments
can only be performed using contrast-enhanced magnetic resonance imaging (MRI).
MRI scan slices of 1 mm are necessary for brain metastases between 5 and 10 mm in
size.
- The lesion(s) must be newly diagnosed or be present as progression after local
therapy, including surgery and/or radiation therapy. For patients who have
received local therapy, progression of pre-existing lesions based on RECIST v1.1
(>20% increase in longest diameter on baseline scan) or new lesions are required.
- Participants who are receiving corticosteroids must be on a stable or decreasing
dose for at least 2 weeks prior to the first dose of study treatment.
- For patients with suspected LM or CM based on imaging, spinal fluid sampling for
confirmation is not required. For patients who do undergo spinal fluid sampling,
those with negative spinal fluid (CSF) are eligible to enter.

- Hemoglobin = 9 g/dL
- Adequate renal function, including:
- Serum creatinine =1.5x the upper limit of normal (ULN) or an estimated glomerular
filtration rate (eGFR) calculated using the Modification of Diet in Renal Disease
(MDRD) equation of at least 45 mL/min/1.73 m2
- Adequate pancreatic function, including:
- Serum lipase = 1.5x ULN
- Adequate liver function, including:
- Total serum bilirubin = 1.5x ULN

the absence of known metastatic involvement of the liver or AST and ALT = 5.0x
ULN if there is metastatic liver involvement.
- Alkaline phosphatase = 2.5x ULN in the absence of known bone metastases or = 5.0x
ULN in the case of bone metastases.
- After progression on or intolerance to prior ALK or ROS inhibitor therapy:
- A minimum washout period of at least 5 half-lives between the last dose of ALK or
ROS inhibitor therapy and the first dose of study treatment is required. A
shorter washout period may be considered in the event of disease flare, after
discussion with the Sponsor.
- Patients must have recovered from treatment toxicities to = Grade 1 or to their
pretreatment levels except for adverse events (AEs) that in the investigator's
judgment do not constitute a safety risk for the patient.
- Patients can either be chemotherapy-naive or have received at least one line of
platinum-based chemotherapy for locally advanced or metastatic disease. Acute effects
of therapy must have resolved to baseline severity or to CTCAE grade =1 except for AEs
that in the investigator's judgment do not constitute a safety risk for the patient.

days before the first dose of study treatment
- For all women of childbearing potential, a negative pregnancy test must be obtained at
the baseline visit before starting study treatment.

amenorrhea) or surgically sterile (absence of ovaries and/or uterus): agreement
to remain abstinent or use two adequate methods of contraception, including at
least one method with a failure rate of < 1% per year, during the treatment
period and for at least 90 days after the last dose of study drug.
- Abstinence is only acceptable if it is in line with the preferred and usual
lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation,
symptothermal, or post-ovulation methods) and withdrawal are not acceptable
methods of contraception.
- Examples of contraceptive methods with a failure rate of < 1% per year include
tubal ligation, male sterilization, hormonal implants, established, proper use of
combined oral or injected hormonal contraceptives, and certain intrauterine
devices. Alternatively, two methods (e.g., two barrier methods such as a condom
and a cervical cap) may be combined to achieve a failure rate of <1% per year.
Barrier methods must always be supplemented with the use of a spermicide.
- For men: agreement to remain abstinent or use a barrier method of contraception
(e.g., condom) during the treatment period and for at least 90 days after the
last dose of study drug and agreement to refrain from donating sperm during this
same period
- Men with a pregnant partner must agree to remain abstinent or use a condom for
the duration of the pregnancy.
- Abstinence is only acceptable if it is in line with the preferred and usual
lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation,
symptothermal, or postovulation methods) and withdrawal are not acceptable
methods of contraception.
- Ability to understand and the willingness to sign a written informed consent document.

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to lorlatinib.
Other severe acute or chronic medical or psychiatric condition, including recent (within
the past year) or active suicidal ideation or behavior, or laboratory abnormality that may
increase the risk associated with study participation or investigational product
administration or may interfere with the interpretation of study results and, in the
judgment of the investigator, would make the patient inappropriate for entry into this
study.
