  • Parts 1a and 1b (Dose Escalation + Fulvestrant):
  • Patient has histological or cytological confirmation of breast cancer.
  • Patient has metastatic disease or locoregionally recurrent disease which is refractory or intolerant to existing therapy(ies) known to provide clinical benefit.
  • Patient has had prior chemotherapy, endocrine therapy, or other therapy as follows:
  • Minimum of one prior line of therapy for advanced/metastatic disease.
  • Maximum of five prior lines of therapy for advanced/metastatic disease.
  • Recurrence or progression on at least one line of endocrine therapy in the advanced/metastatic disease setting.
  • Prior treatment has included a CDK4/6 inhibitor.
  • Tumor is ER+ (defined as ER IHC staining \> 0%).
  • Cohort EMNK:
  • Patient has undergone treatment with platinum-based chemotherapy and an anti-PD-1/L1 agent, if appropriate.
  • Tumor has a known KRAS-activating mutation; Patients with KRAS G12C mutations are excluded.
  • Cohort EMBF:

  • Minimum of one prior line of therapy for advanced/metastatic disease.
  • Maximum of five prior lines of therapy for advanced/metastatic disease.
  • Recurrence or progression on at least one line of endocrine therapy in the advanced/metastatic disease setting, which may include combination therapy (eg, with a CDK4/6 inhibitor).
  • Tumor is ER+ (defined as ER IHC staining \> 0%) and has FGFR amplification.
  • Cohort EMBH:
  • Patient has had prior chemotherapy, endocrine therapy, or other therapy as follows:

  • Cohort ECNS:
  • Patient has histologically or cytologically confirmed stage IIIB (pleural or pericardial effusion) or stage IV NSCLC.
  • Patient has undergone treatment with platinum-based chemotherapy and an anti-PD-1/L1 agent, if appropriate. Note: Patients who have declined approved therapy(ies) or who per treating physician are not eligible for approved therapy(ies) (eg, due to intolerance) may be eligible following discussion with the Medical Monitor.
  • Tumor has a known G12C KRAS-activating mutation. Note: Patients who have been previously treated with KRAS-specific therapy are excluded.
  • Cohort ECBF:
  • Patient has had prior chemotherapy, endocrine therapy, or other therapy as follows:
  • Minimum of one prior line of therapy for advanced/metastatic disease.
  • Maximum of five prior lines of therapy for advanced/metastatic disease.
  • Recurrence or progression on at least one line of endocrine therapy in the advanced/metastatic disease setting.
  • Prior treatment has included a CDK4/6 inhibitor.
  • Tumor is ER+ (defined as ER IHC staining \> 0%).
  • Cohort ECBF+A:
  • Patient has had prior chemotherapy, endocrine therapy, or other therapy as follows:
  • Minimum of one prior line of therapy for advanced/metastatic disease.
  • Maximum of five prior lines of therapy for advanced/metastatic disease.
  • Recurrence or progression on at least one line of endocrine therapy in the advanced/metastatic disease setting.
  • Tumor is ER+ (defined as ER IHC staining \> 0%) and HER2- (defined as absence of HER2 3+ IHC staining and/or absence of FISH+).
  • Cohort ECBT:
  • Patient has progressed after treatment with at least one approved anti-HER2 agent and has been administered at least one line of chemotherapy.
  • Tumor is HER2+ (defined as HER2 3+ IHC staining or HER2 2+ and FISH+). Cohorts EMBF, EMBH, ECBF, ECBF+A: There is no limit on the number of lines of prior endocrine therapies.
  • Cohort ECBF-D1:
  • Patient has metastatic disease or locoregionally recurrent disease which is refractory or intolerant to existing therapy(ies) known to provide clinical benefit.
  • Patient has had prior chemotherapy, endocrine therapy, or other therapy as follows:
  • Minimum of one prior line of therapy for advanced/metastatic disease.
  • Maximum of five prior lines of therapy for advanced/metastatic disease.
  • Recurrence or progression on at least one line of endocrine therapy in the advanced/metastatic disease setting.
  • Prior treatment has included a CDK4/6 inhibitor.
  • Tumor is ER+ (defined as ER IHC staining \> 0%).
