Clinical Trial Summary

This phase II trial tests how well biologically guided radiation therapy (BgRT) and stereotactic body radiation therapy (SBRT) with osimertinib works for the treatment of EGFR positive non-small cell lung carcinoma that has spread from where it first started (primary site) to a limited number of anatomic sites (oligoprogressive). BgRT is radiation that uses specialized imaging to during treatment to target the active tumor and direct radiation to tumors in order to kill and shrink tumor cells. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Osimertinib is in a class of medications called kinase inhibitors. It works by blocking the action of a protein called EGFR that signals cancer cells to multiply. This helps slow or stop the spread of tumor cells. Giving BgRT with SBRT and osimertinib may kill more tumor cells in patients with oligoprogressive EGFR positive non-small cell lung carcinoma.

Description:

PRIMARY OBJECTIVE:

I. To estimate the percent of patients receiving benefit at 6 months from the addition of BgRT/SBRT to first line osimertinib in EGFR positive non-small cell lung cancer (NSCLC) patients with oligoprogressive disease (disease control rate [DCR]).

SECONDARY OBJECTIVES:

I. To evaluate the tolerability of adding BgRT/SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

II. To estimate the overall survival when adding BgRT/SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

III. To describe the effect on quality of life (QOL) when adding BgRT/SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

IV. To describe the effect on quantified fludeoxyglucose F-18 (FDG) uptake changes when adding BgRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

V. To estimate local and distant control rates when adding BgRT/SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

VI. To estimate the extracranial progression free survival (PFS) when adding SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

VII. To estimate the time to treatment failure (TTF) when adding BgRT/SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

VII. To estimate percentage of patients needing salvage BgRT/SBRT when adding SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

EXPLORATORY OBJECTIVES:

I. To identify potential predictors of outcome when adding BgRT/SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

II. To describe the changes in circulating tumor deoxyribonucleic acid (ctDNA) levels when adding BgRT/SBRT to first line osimertinib in EGFR positive NSCLC patients with oligoprogressive disease.

OUTLINE:

Patients continue to receive osimertinib orally (PO) daily (QD) in the absence of unacceptable toxicity. Patients undergo BgRT/SBRT every other day for 5 treatments. Patients then continue to receive osimertinib and are monitored via imaging. If additional progression is found, patients may receive additional BgRT/SBRT therapy. Treatment continues in the absence of > 5 sites of progression, unacceptable toxicity, or the stopping of osimertinib for more than 4 weeks.

Patients undergo computed tomography (CT) scan or positron emission tomography(PET)/CT scan and blood sample collection throughout the study.

After completion of initial radiation therapy, patients follow up at 1 week, 3 months, 6 months and 12 months and then for an additional year.

• Assent, when appropriate, will be obtained per institutional guidelines

• Age: >= 18 years

• Eastern Cooperative Oncology Group (ECOG) =< 2

• Histologically confirmed advanced non-small cell lung cancer (NSCLC)

• The tumor harbors 1 of the 2 common epidermal growth factor receptor (EGFR) mutations known to be associated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) sensitivity (Ex19del or L858R), either alone or in combination with other epidermal growth factor receptor (EGFR) mutations, which may include T790M.

• Disease progression must be in the form of 1-5 extracranial sites (any number of metastatic sites at initial diagnosis will qualify). For progression of the primary and oligoprogressive site(s), the primary should be treated with curative/local control intent. The primary, if progressing is considered as 1 site. Maximum of 3 lesions per organ (i.e. patient with 4 oligoprogressive sites in the lung would be excluded). Each lesion will be considered as 1 "site" so 3 lesions in the lung for example will be considered 3 sites. Patients with prior metastases that have been treated with ablative therapies before their current line of systemic therapy are eligible. Patients with brain metastases can be included but brain metastases must be treated (asymptomatic and have had no requirement for steroid medication for 1 week prior to the first dose of study drug and have completed radiation 2 weeks prior to the first dose of study drug) prior to enrollment (brain metastases [mets] will not be counted as a site of progression)

• Lesion(s) must be amenable to SBRT as determined by the radiation oncologist. If a patient is unable to receive a minimum of 30 Gy in 5 fractions they will not qualify

• At least one lesion must be amenable to BgRT which includes either a lung or bone metastasis, greater than or equal to 2 cm, which can also receive a minimum of 30 Gy in 5 fractions

• No prior systemic therapy for advanced disease other than osimertinib

• Women of childbearing potential (WOCBP): negative urine or serum pregnancy test If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required

• Agreement by females and males of childbearing potential* to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 4 months after the last dose of protocol therapy

• Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for > 1 year (women only)

• Patients must be able to swallow and retain oral medications

• Life expectancy of at least 6 months

Exclusion Criteria:

• Chemotherapy, radiation therapy, biological therapy, immunotherapy within 21 days prior to day 1 of protocol therapy (6 weeks for nitrosoureas or mitomycin C). Exceptions to this exclusion are brain radiation (2 weeks) and osimertinib

• Strong CYP3A4 inducers/ inhibitors within 14 days prior to day 1 of protocol therapy

• Patients receiving class 1A or class III antiarrhythmic agents within 14 days prior to day 1 of protocol therapy

Patients with a history of low grade (Gleason score =< 6 =Gleason group 1) localized prostate cancer will be eligible even if diagnosed less than 5 years prior to study entry. Other malignancies with low probability of recurrence may be allowed with primary investigator (PI) approval

• Females only: Pregnant or breastfeeding

• Any malabsorption condition

• Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures
