Brief Summary:
This is a phase II, single-arm, open-label study evaluating the efficacy, safety and tolerability of neoadjuvant sotorasib in combination with cisplatin (or carboplatin) and pemetrexed chemotherapy for patients with surgically resectable stage IIA - IIIB (T3-T4/N2) (based on AJCC 8th edition), non-squamous NSCLC with a KRAS p.G12C mutation. The primary objective of the study is to determine whether neoadjuvant therapy with 4 cycles of at least one dose of sotorasib plus cisplatin (or carboplatin) and pemetrexed can be administered safely and result in improved MPR rate in patients with KRAS p.G12C-mutant non-squamous NSCLC compared with the historical control MPR rate for platinum-based chemotherapy alone.

Criteria

Inclusion Criteria

  1. [*] Subject or subject's legally acceptable representative has provided signed and dated written informed consent prior to initiation of any study specific activities/procedures in accordance with ICH-GCP guidelines and the local legislation.
  2. [*]Age > 18 years old.
  3. [*]Histologically or cytologically confirmed previously untreated non-squamous non-small cell lung cancer. If a diagnostic biopsy is available, a pre-treatment biopsy is not required. Patients with a suspected lung cancer are eligible, but pathology must be confirmed prior to initiating treatment on study. Pure squamous cell carcinomas are not eligible but mixed histologies (for example adenosquamous carcinoma) are eligible. Sarcomatoid carcinomas are not eligible.

    Neuroendocrine carcinomas are not eligible. Carcinomas with neuroendocrine differentiation are eligible. Patients with mixed small-cell lung cancer and NSCLC are not eligible.

  4. Identification of a KRAS p.G12C mutation in tumor tissue or plasma by an approved diagnostic device for detection of KRAS p.G12C in NSCLC or through any nucleic acid-based diagnostic testing method [including droplet-digital PCR, real-time PCR based methods such as the Idylla KRAS Mutation Assay (Biocartis), tissue and circulating tumor DNA -based next generation sequencing, Sanger-sequencing etc] performed in a Clinical Laboratory Improvement Amendments (CLIA)-certified or equivalently accredited laboratory. Patients meeting [*] highlighted criteria will be offered study-provided droplet digital PCR or alternative PCR-based method such as the Idylla KRAS Mutation Assay (Biocartis) for detection of KRAS p.G12C using tumor tissue (1st choice if adequate tissue is available) or plasma (if tumor tissue is not available or cannot be accessed within 5 working days). Turnaround time for reporting of the presence or absence of a KRAS p.G12C mutation will be ≤ 5 working daysfor plasma-based testing and ≤7 working days from the date of confirmation of tissue availability for tissue-based testing. If analysis of tumor tissue fails due to technical reasons, the same patient can undergo analysis of circulating tumor DNA using droplet-digital PCR or alternative PCR-based method such as the Idylla KRAS Mutation Assay (Biocartis). If plasma-based analysis failes to detect a KRAS p.G12C mutation and tumor tissue becomes available, the same patient can undergo analysis of tumor tissue using droplet digital PCR or alternative PCR-based method such as the Idylla KRAS Mutation Assay (Biocartis).
  5. Patients with disease stage IIA to select stage IIIB (T3-4N2) (according to version 8 of the International Association for the Study of Lung Cancer Staging Manual in Thoracic Oncology [IASLC Staging Manual in Thoracic Oncology 2016]). Patients with multistation N2 disease are eligible provided that complete surgical resection is considered feasible by multidisciplinary evaluation which must include a thoracic surgeon that performs lung cancer surgery as a prominent part of his/her practice Invasive mediastinal staging with endosonography (EBUS or EUS) with fine-needle aspiration (FNA) and/or mediastinoscopy should be completed within 42 days from the start of treatment in the following cases:

    • In case of mediastinal lymph nodes that are enlarged by CT criteria and/or PET-positive mediastinal lymph nodes.
    • In case of tumors > 3 cm in maximum diameter
    • In case of centrally located tumors
    • For tumors with N1 nodes (cN1) Invasive mediastinal staging should include evaluation of contralateral stations 2 and/or 4 to exclude N3 disease as well as of subcarinal (station 7) lymph nodes. When there are no enlarged mediastinal lymph nodes by CT criteria and there is no uptake on PET/CT (cN0) direct surgical resection with lymph node dissection is indicated for tumors ≤ 3cm that are located in the outer third of the lung.
  6. [*] Absence of unequivocal evidence of stage IV disease based on contrast-enhanced CT chest, abdomen, pelvis or PET/CT and brain MRI with IV contrast (or contrast-enhanced CT of the head) performed within 60 days is sufficient for study registration but must be confirmed with whole-body PET/CT as well as contrast-enhanced CT chest and abdomen (or contrast-enhanced CT chest including the whole liver and both adrenal glands) and brain MRI with IV contrast (or contrast-enhanced CT of the head) within 28 days prior to the start of treatment. Patients with lesions that are considered equivocal for metastatic disease in the opinion of the local principal investigator are elibile to register and undergo molecular testing if they meet all other [*] marked criteria but must meet the full trial eligibility criteria prior to study enrollment. In patients with severe allergy to iodinated contrast absence of stage IV disease on PET/CT and brain MRI with IV contrast performed within 28 days prior to enrollment suffices to satisfy this eligibility criterion.

Patients with cardiac arrhythmias that are adequately controlled with medication (for example chronic, rate controlled atrial fibrillation) are potentially eligible if they are deemed to be surgical candidates and do not meet other exclusion criteria. Patients with 1st degree atrioventricular [AV] block or asymptomatic left anterior fascicular block [LAFB/right bundle branch block [RBBB] are eligible.
  9. [*]Gastrointestinal (GI ) tract disease causing inability to take oral medication, refractory nausea and vomiting, uncontrolled diarrhea, significant small bowel resection or gastric bypass surgery, use of feeding tubes, malabsorption syndrome, requirement for intravenous alimentation, or uncontrolled inflammatory GI disease (for example Crohn's disease, ulcerative colitis).

  13. [*]Serious illness or concomitant non-oncological disease such as neurologic, psychiatric, infectious disease or laboratory abnormality that may increase the risk associated with study participation or study drug administration and in the judgment of the treating physician (local principal investigator or sub-investigator)would make the patient inappropriate for entry into the study.
  14. Patients with newly diagnosed (as documented by an audiology assessment performed prior to study enrollment) or pre-existing moderate or severe sensorineural hearing loss are not eligible to receive cisplatin but may be treated with carboplatin following discussion of the risks and benefits at the discretion of the treating physician.

  17. [*]Psychological,familial,sociological or geographicalfactors potentially hampering compliance with the study protocol and follow-up schedule.
  18. Positive test for hepatitis B virus surface antigen (HBsAg). If the patient is negative for HBsAg) but has positive hepatitis B core antibody, then hepatitis B surface antibody [Anti-HBs] testing is necessary (Hepatitis B core antibody testing is not required for screening but if this is done and is positive, then anti-HBs testing is necessary). Undetectable anti-HBs in this setting would suggest unclear and possible infecition and needs exclusion. Patients receiving antiviral therapy for Hepatitis B or C are not eligible.
  19. Positive Hepatitis C virus antibody. In this case hepatitis C virus ribonucleic acid [HCV RNA] is necessary. Detectable HCV RNA indicating acute or chronic infection renders the subject ineligible.
  20. [*]Known history of testing positive for human immunodeficiency virus or known acquired immunodeficiencysyndrome.
