About

This research study is studying a drug as a possible treatment for ALK-positive or ROS1-positive non-small cell lung cancer (NSCLC).

The following drug will be involved in this study :

Lorlatinib

Full description

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. The FDA (the U.S. Food and Drug Administration) has not approved Lorlatinib as a treatment for any disease.

All participants in this study will receive Lorlatinib. Lorlatinib targets the abnormal ALK or ROS1 proteins in NSCLC cells. Lorlatinib has been tested in other research studies and results show that the medicine may help to control the growth of NSCLC even after it has spread to the CNS. The CNS is a term used to refer to the brain and spinal cord, including the lining of the brain and spinal cord which is called the meninges.

In this research study, the investigators are trying to determine whether lorlatinib is effective in controlling the growth of cancer cells after they have spread to the CNS. Another purpose of this study is to determine why the cancer cells that have spread to the participant CNS have continued to grow despite treatment with other drugs. For this reason, blood samples will be collected as part of this study to assess the DNA released by the participants cancer cells into their blood when the cells travel to other sites in their body.

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.
Age ≥ 18 years
Eastern Cooperative Oncology Group (ECOG) performance status ≤2 (Karnofsky ≥60%)
Life expectancy of ≥ 12 weeks, in the opinion of the investigator
Adequate hematologic function, including:
- Platelet count ≥ 100 x 109/L
- Absolute neutrophil count (ANC) ≥ 1,500/µL
- 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
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3.0x ULN in 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.
Recovery from effects of any major surgery or significant traumatic injury at least 28 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.
- For women who are not postmenopausal (≥ 12 months of non-therapy-induced 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.
