Clinical Trial Summary

This study will consist of a Phase 1b and Phase 2 portion. The Phase 1b portion will enroll first followed by the Phase 2 portion. Each cycle of treatment = 28 days.

Subjects will receive alectinib twice daily. Those in the Phase 1b portion will receive alectinib alone. Those in Phase 2 Arm A will receive alectinib alone. Those in Phase 2, Arm B will receive SRS + alectinib.

A maximum of 25 cycles (2 years) of alectinib may be administered on study.

Eligibility

General Inclusion Criteria:

Subject must meet all of the following applicable inclusion criteria to participate in this study:

1. Written informed consent and HIPAA authorization for release of personal health information prior to registration. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.

2. Age = 18 years at the time of consent.

3. First language must be English.

4. ECOG Performance Status of = 2 within 14 days prior to registration.

5. Histological or cytological confirmation of Stage IV (per AJCC 8th edition) non-small cell lung cancer (NSCLC).

6. At least one intracranial metastasis on MRI imaging.

7. Confirmation of positive ALK rearrangement per local standard of care testing.

8. All subjects must have brain metastases and be either asymptomatic or minimally symptomatic per investigator discretion without plan for surgical intervention within 28 days of study start. Patients with neurological symptoms that are controlled with dose of corticosteroids or anti-epileptic medications are eligible. Patients with asymptomatic leptomeningeal disease may be eligible for trial providing they meet all other eligibility criteria.

9. Subjects must be planning on therapy with alectinib. Alectinib may have been started up to 6 weeks prior to radiation.

10. Prior non-ALK directed therapy for metastatic disease is permitted. Patients who have received prior neoadjuvant, adjuvant chemotherapy, radiotherapy, immunotherapy (PD-1 or PD-L1 monoclonal antibodies) or chemoradiotherapy with curative intent for non-metastatic disease must have experienced a treatment-free interval of at least 3 months from registration since the last chemotherapy, radiotherapy, immunotherapy, or chemoradiotherapy cycle.

11. Documentation of consultation with a radiation oncologist confirming agreement to delay radiation therapy.

12. Demonstrate adequate organ function as defined in the protocol. All screening labs to be obtained within 14 days prior to registration.

13. Females of childbearing potential must have a negative serum pregnancy test within 14 days prior to registration. See protocol for definition of childbearing potential.

14. Females of childbearing potential and males must be willing to abstain from heterosexual intercourse or to use an effective method(s) of contraception as outlined in the protocol.

15. HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months of registration are eligible for this trial.

16. Patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated. Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, the HCV viral load must be undetectable to be eligible for this trial.

17. As determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study.

Exclusion Criteria:

Subjects meeting any of the criteria below may not participate in the study:

1. Active infection requiring systemic therapy.

2. Malabsorption syndrome or other condition that would interfere with enteral absorption

3. Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study).

4. Patients with a prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen, per treating physician discretion, are not eligible for this trial.

5. Treatment with any investigational drug within 28 days prior to registration.

6. History of other malignancy within 5 years prior to screening, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or Stage I uterine cancer.

7. Acute viral, autoimmune, alcoholic, or other types of acute hepatitis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Phase 2: Neurological status and control of CNS disease at 12 months compared to alectinib plus SRS in patients with =15 CNS metastases	Neurological status will be measured by a composite endpoint of: -Inntracranial progression(icPD) by RANO-BM criteria or death during the first 12 months.; OR; -Symptomatic radiation necrosis during the first 12 months. Symptomatic radiation necrosis is defined as requiring initiation of or increased dose of steroids or resulting in seizures or requirement of AEDs or requirement of hospitalization or surgery.; OR; -Cognitive decline, defined as 1 standard deviation decline from baseline cognitive function during the first 12 months.	12 months
Primary	Phase 1b: Safety and Feasibility	Safety and feasibility will be assessed by frequency of Dose Limiting Toxicities.	6 months
Secondary	Intracranial progression-free survival at 12 months (icPFS12)	icPFS12 is the percentage of patients with icPD at 12 months defined by RANO-BM from randomization or death.	12 months
Secondary	Intracranial disease control rate (icDCR)	icDCR defined as the percentage of patients with a complete response (CR), partial response (PR), or stable disease (SD), per RANO-BM.	31 months
Secondary	Intracranial response rate (icRR)	icRR defined as the percentage of patients with a complete response (CR) and partial response (PR), per RANO-BM.	31 months
Secondary	Intracranial duration of response (icDOR)	icDOR defined as the time when the criteria for CR or PR per RANO-BM were first met to the occurrence of an icPFS event	31 months
Secondary	Extracranial PFS	Extracranial PFS will be defined as time from randomization to progression per RECIST v1.1	31 months
Secondary	Assess Overall survival (OS)	OS defined as the time from randomization to death from any cause.	31 months
Secondary	Safety and Tolerability	Safety and tolerability will be assessed by measuring the frequency and severity of adverse events based on CTCAE v5.0	6 months
Secondary	Cognitive decline at 12 and 24 months	Rate of cognitive decline, defined as 1 standard deviation decline from baseline cognitive function in at least 1 cognitive test.	12, 24 months
Secondary	Symptomatic radiation necrosis at 12 and 24 months	Incidence of symptomatic radiation necrosis, defined as requiring initiation of or increased dose of steroids or resulting in seizures or requirement of AEDs or requirement of hospitalization or surgery.	12, 24 months
