Más betegség

• Known or suspected hypersensitivity or severe allergy to active ingredient/excipients of PF-07248144.

Laborértékek

• ECG clinically relevant abnormalities (eg, QTc >470 msec, complete LBBB, second/third degree AV block, ST elevation or EKG changes suggesting myocardial infarction or active myocardia ischemia).

Egyéb

• Unmanageable ascites (limited medical treatment to control ascites is permitted, but all participants with ascites require review by sponsor's medical monitor).
• Pregnant or breastfeeding female participants.

• Disease Characteristics - Breast, Prostate, and Lung Cancer
• Part 1A (Monotherapy Dose Escalation) Histological or cytological diagnosis of locally advanced or metastatic ER+HER2- breast cancer, CRPC, or NSCLC that is intolerant or resistant to standard therapy or for which no standard therapy is available.
• Part 1B, Part 1C, Part 1D and Part 1E (Combination Dose Escalation) Histological or cytological diagnosis of locally advanced or metastatic ER+HER2- breast cancer. Participants must have progressed after at least 1 prior line of treatment with an endocrine therapy and CDK4/6 inhibitor in the advanced or metastatic setting.
• Part 2A (ER+HER2- breast cancer 2L+, monotherapy) Histological or cytological diagnosis of locally advanced or metastatic ER+HER2- breast cancer. Participants must have progressed after at least 1 prior line of CDK4/6 inhibitor and 1 line of endocrine therapy.
• Part 2B (ER+HER2- breast cancer 2-4L, combination with fulvestrant) Histological or cytological diagnosis of advanced or metastatic ER+HER2- breast cancer. Participants must have progressive disease after at least 1 prior line of a CDK4/6 inhibitor and at least 1 prior line of endocrine therapy.. Participants must not have received more than 3 prior lines of systemic therapies including up to 1 line of cytotoxic chemotherapy for visceral disease in advanced or metastatic setting; Participants may have but are not required to have prior treatment with fulvestrant.
• Part 2D (ER+HER2- breast cancer 2-4L, combination with PF-07220060 (CDK4i) and fulvestrant):
  • Histological or cytological diagnosis of advanced or metastatic ER+HER2- breast cancer. Participants must have progressive disease after at least 1 prior line of a CDK4/6 inhibitor and at least 1 prior line of endocrine therapy.
• Participants must have not received more than 3 lines of systemic therapies including up to 1 line of cytotoxic chemotherapy for visceral disease in advanced or metastatic setting; Participants may have but are not required to have prior treatment with fulvestrant.
• Part 2E (ER+HER2- breast cancer 2-4L, combination with vepdegestrant): Histological or cytological diagnosis of advanced or metastatic ER+HER2- breast cancer. Participants must have progressive disease after at least 1 prior line of a CDK4/6 inhibitor and at least 1 prior line of endocrine therapy; Participants must have not received more than 3 lines of systemic therapies including up to 1 line of cytotoxic chemotherapy for visceral disease in advanced or metastatic setting; Participants may have received fulvestrant
• Participants with ER+HER2- advanced or metastatic breast cancer must have documentation of ER-positive tumor (≥1% positive stained cells) based on most recent tumor biopsy utilizing an assay consistent with local standards.
• Participants with ER+HER2- advanced or metastatic breast cancer must have documentation of HER2-negative tumor: HER2-negative tumor is determined as immunohistochemistry score 0/1+ or negative by in situ hybridization (FISH/CISH/SISH/DISH) defined as a HER2/CEP17 ratio <2 or for single probe assessment a HER2 copy number <4.
• Female participants with ER+HER2- advanced or metastatic breast cancer considered to be of childbearing potential (or have tubal ligations only) must be willing to undergo medically induced menopause by treatment with the approved LHRH agonist such as goserelin, leuprolide or equivalent agents to induce chemical menopause.
• Female participants with ER+HER2- advanced or metastatic breast cancer of nonchildbearing potential must meet at least 1 criteria of achieving postmenopausal status.
• Participants must have at least 1 measurable lesion as defined by RECIST version 1.1 that has not been previously irradiated.
• Eastern Cooperative Oncology Group (ECOG) Performance Status PS 0 or 1
• Female or male patients aged ≥ 18 years (Japan ≥ 20 years) (South Korea ≥ 19 years).
• Adequate renal, liver, and bone marrow function.
• Resolved acute effects of any prior therapy to baseline severity or CTCAE Grade 1 except for adverse events (AEs) not constituting a safety risk by investigator judgment.
