Adjuvant Treatment With Cisplatin-based Chemotherapy Plus Concomitant Atezolizumab in Patients With Stage I (Tumors ≥ 4cm), IIA, IIB, and Select IIIA [T3N1-2, T4N0-2] Resected Non-small Cell Lung Cancer (NSCLC) and the Clearance of Circulating Tumor DNA (ctDNA)

NCT04367311

Description:

The vast majority of patients with stage I (tumors ≥ 4cm), IIA, IIB (and select IIIA) NSCLC are managed with upfront surgery, followed by adjuvant chemotherapy. However, relapse rates remain high and are primarily due to distant, metastatic disease. Previous meta-analysis evaluating the use of neo-adjuvant chemotherapy and adjuvant chemotherapy demonstrate a similar impact on improved disease free survival (DFS) and overall survival (OS). The role of checkpoint inhibitors has been proven to be effective in the treatment of patients with advanced NSCLC, regardless of histology and PD-L1 expression. Results from trials evaluating the use of checkpoint inhibitors alone or in combination with chemotherapy in the neoadjuvant setting for early stage disease are promising. However, there are no trials evaluating the role of concomitant chemotherapy and checkpoint inhibitors in the adjuvant setting. In addition, emerging data supports the use of ctDNA as a promising biomarker for early detection of minimal residual disease and have indicated that the presence of detectable ctDNA after surgery for localized lung cancer is correlated with a 90-100% chance for disease recurrence. Therefore, we propose this current study assessing concomitant chemotherapy plus Atezolizumab in the adjuvant setting for patients with stage I (tumors ≥ 4cm), IIA, IIB (and select IIIA) NSCLC who have detectable ctDNA after surgery. The clearance of ctDNA will serve as a surrogate for long term DFS and OS in this patient population.

The vast majority of patients with stage I (tumors ≥ 4cm), IIA, IIB (and select IIIA) NSCLC are managed with upfront surgery, followed by adjuvant chemotherapy. However, relapse rates remain high and are primarily due to distant, metastatic disease. Previous meta-analysis evaluating the use of neo-adjuvant chemotherapy and adjuvant chemotherapy demonstrate a similar impact on improved disease free survival (DFS) and overall survival (OS). The role of checkpoint inhibitors has been proven to be effective in the treatment of patients with advanced NSCLC, regardless of histology and PD-L1 expression. Results from trials evaluating the use of checkpoint inhibitors alone or in combination with chemotherapy in the neoadjuvant setting for early stage disease are promising. However, there are no trials evaluating the role of concomitant chemotherapy and checkpoint inhibitors in the adjuvant setting. In addition, emerging data supports the use of ctDNA as a promising biomarker for early detection of minimal residual disease and have indicated that the presence of detectable ctDNA after surgery for localized lung cancer is correlated with a 90-100% chance for disease recurrence. Therefore, we propose this current study assessing concomitant chemotherapy plus Atezolizumab in the adjuvant setting for patients with stage I (tumors ≥ 4cm), IIA, IIB (and select IIIA) NSCLC who have detectable ctDNA after surgery.

Eligibility Criteria

        Inclusion Criteria:

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

          -  Age >= 18 years at the time of consent.

          -  ECOG Performance Status of 0-1 within 28 days prior to registration.

          -  Patients must have undergone complete surgical resection of their stage I (tumors >=
             4cm), IIA, IIB, and select IIIA [T3N1-2, T4N0-2] NSCLC according to the AJCC 8th
             edition with negative margins (R0).

          -  Squamous or non-squamous NSCLC histology. Cancers with a histology of "adenosquamous"
             are considered a type of adenocarcinoma and thus "non-squamous histology".

          -  Surgery for this lung cancer must be completed <= 60 days prior to starting treatment.

          -  Must have tissue available to perform prospective correlative testing. Tissue block is
             preferred but 10-15 unstained slides (5 μm thick) are also acceptable. If prior PD-L1
             results with Dako 22C3 antibody are not available, an additional 5 unstained slides (4
             μm thick) must be submitted.

          -  Demonstrate adequate organ function as defined in the protocol; all screening labs to
             be obtained within 28 days prior to registration.

          -  Females of childbearing potential must have a negative serum pregnancy test within 7
             days prior to registration NOTE: Females are considered of childbearing potential
             unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal
             ligation, or bilateral oophorectomy) or they are naturally postmenopausal for at least
             12 consecutive months

          -  For women of childbearing potential: agreement to remain abstinent (refrain from
             heterosexual intercourse) or use contraceptive methods, and agreement to refrain from
             donating eggs, as defined below:

               -  Women must remain abstinent or use contraceptive methods with a failure rate of <
                  1% per year during the treatment period and for 5 months after the final dose of
                  atezolizumab.

               -  A woman is considered of childbearing potential if she is postmenarchal, has not
                  reached a postmenopausal state (> or equal to 12 continuous months of amenorrhea
                  with no identified cause other than menopause), and has not undergone surgical
                  sterilization (removal of ovaries and/or uterus). The definition of childbearing
                  potential may be adapted for alignment with local guidelines or requirements.

               -  Examples of contraceptive methods with a failure rate of < 1% per year include
                  bilateral tubal ligation, male sterilization, hormonal contraceptives that
                  inhibit ovulation, hormone-releasing intrauterine devices, and copper
                  intrauterine devices.

               -  The reliability of sexual abstinence should be evaluated in relation to the
                  duration of the clinical trial and 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.

          -  Contraception method must begin starting from the time of informed consent until 5
             months after treatment discontinuation.

          -  For men: Agreement to remain abstinent (refrain from heterosexual intercourse) or use
             a condom, and agreement to refrain from donating sperm, as defined below:

               -  With female partners of childbearing potential or pregnant female partners, men
                  must remain abstinent or use a condom during the treatment period and for 5
                  months after the last dose of study treatment to avoid exposing the embryo. Men
                  must refrain from donating sperm during this same period.

               -  The reliability of sexual abstinence should be evaluated in relation to the
                  duration of the clinical trial and 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.
