  • Adequate hepatic laboratory assessments, as follows: 
    • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 times the upper limit of normal (ULN), except if alkaline phosphatase > 2.5 times the ULN, then AST and/or ALT must be ≤ 1.5 times the ULN
    • Total bilirubin ≤ ULN
  • Adequate coagulation laboratory assessments, as follows:
    • Partial prothrombin time (PTT) or partial thromboplastin time (PTT) < 1.5 x ULN, OR international normalized ratio (INR) < 1.5 x ULN or within target range if on prophylactic anticoagulation therapy

• Key Exclusion Criteria

  A patient will not be eligible for participation in this study if any of the following criteria apply.

  • Mixed small-cell lung cancer and NSCLC histology
  • Active brain metastases and/or carcinomatous meningitis from non-brain tumors. Subjects who have had brain metastases resected or have received radiation therapy ending at least 4 weeks prior to study day 1 are eligible if they meet all of the following criteria: a) residual neurological symptoms grade ≤ 2; b) on stable doses of dexamethasone, if applicable; and c) follow-up MRI performed within 30 days shows no new lesions appearing
  • Leptomeningeal disease.
  • Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures at a frequency greater than monthly. Patients with PleurX catheters in place may be considered for the study with Medical Monitor approval.
  • History or presence of hematological malignancies unless curatively treated with no evidence of disease ≥ 2 years
  • History of other malignancy within the past 2 years, with the following exceptions:
    • Malignancy treated with curative intent and with no known active disease present for ≥ 2 years before enrollment and felt to be at low risk for recurrence by the treating physician.
    • Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
    • Adequately treated cervical carcinoma in situ without evidence of disease.
    • Adequately treated breast ductal carcinoma in situ without evidence of disease.
    • Prostatic intraepithelial neoplasia without evidence of prostate cancer.
    • Adequately treated urothelial papillary noninvasive carcinoma or carcinoma
      in situ.
  • Myocardial infarction within 6 months of study day 1, symptomatic congestive heart failure (New York Heart Association > class II), unstable angina, or cardiac arrhythmia requiring medication
  • Gastrointestinal (GI) tract disease causing the inability to take oral medication, malabsorption syndrome, requirement for IV alimentation, uncontrolled inflammatory GI disease (eg, Crohn’s disease, ulcerative colitis)
  • Evidence of hepatitis infection based on the following results and/or
    criteria:
    • Positive Hepatitis B Surface Antigen (HepBsAg) (indicative of chronic Hepatitis B or recent acute Hepatitis B)
    • Negative HepBsAg with a positive for Hepatitis B core antibody (Hepatitis B core antibody testing is not required for screening, however if this is done and is positive, then Hepatitis B surface antibody [anti-HBs] testing is necessary. Undetectable, anti-HBs in this setting would suggest unclear and possible infection, and needs exclusion)
    • Positive Hepatitis C virus antibody: Hepatitis C virus RNA by polymerase chain reaction (PCR) is necessary. Detectable Hepatitis C virus RNA suggests chronic Hepatitis C.
  • Known positive test for human immunodeficiency virus (HIV).
  • Is unwilling to take corticosteroid premedication for pemetrexed or docetaxel.
  • Is unable or unwilling to take folic acid or vitamin B12 supplementation.
  • Has an active infection requiring systemic therapy.
  • Prior therapy with AMG 510
  • Anti-tumor therapy (chemotherapy, antibody therapy, molecular targeted therapy, retinoid therapy, hormonal therapy, or investigational agent) within 28 days of study day 1
  • Therapeutic or palliative radiation therapy within 2 weeks of study day 1. Subjects must have recovered from all radiotherapy related toxicity.
  • Received radiation therapy to the lung that is > 30 Gy within 6 months of the first dose of trial treatment
  • Use of known cytochrome P450 (CYP) 3A4 sensitive substrates (with a narrow therapeutic window) or Pgp substrates, within 14 days or 5 halflives of the study drug or its major active metabolite, whichever is longer, prior to study day 1 that was not reviewed and approved by the principal investigator and the Amgen medical monitor
  • Use of strong inducers of CYP3A4 (including herbal supplements such as St. John’s wort) within 14 days or 5 half-lives (whichever is longer) prior to study day 1 that was not reviewed and approved by the principal investigator and the Amgen medical monitor.
  • Unresolved toxicities from prior anti-tumor therapy, defined as not having resolved to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade 0 or 1, or to levels dictated in the eligibility criteria with
    the exception of alopecia (grade 2 or 3 toxicities from prior anti-tumor therapy that are considered irreversible [defined as having been present and stable for > 6 months], such as ifosfamide, related proteinuria, may be allowed if they are not otherwise described in the exclusion criteria AND there is agreement to allow by both the investigator and sponsor).
  • Subject unable to receive both iodinated contrasts for CT scans and gadolinium contrast for MRI scans
  • Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette- Guérin (BCG), and typhoid vaccine. Season influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg FluMist®) are live attenuated vaccines and are not allowed.
