Eligibility

Inclusion Criteria:

• Subjects fully understand and voluntarily participate in this study and sign informed consent. Left Ventricular Ejection Fraction (LVEF) = 50% within 28 days prior to first dose. Eastern Cooperative Oncology Group performance status( PS) of 0 or 1. Life expectancy = 3 months. Histopathologically or cytologically confirmed advanced/unresectable or metastatic solid malignant tumors that is refractory to or intolerable with standard treatment, or for which no standard treatment is available:

Cohort A: Pathologically documented breast cancer that:

• Is unresectable or metastatic.
• Has a history of low HER2 expression, defined as IHC 2+/ISH- or IHC 1+ (ISH- or untested).
• For HR-positive participants, is documented refractory to endocrine therapy, defined as having progressed on at least 1 endocrine therapy and determined by the investigator that subject would no longer benefit from further treatment from endocrine therapy.
• Was never previously HER2-positive(IHC 3+ or IHC 2+/ISH+) on prior pathology testing or was historically HER2 IHC 0 only.

Cohort B: Pathologically documented endometrial cancer that:

• Is unresectable or metastatic.
• Has a history of HER2 expression, defined as HER2 1+, 2+, or 3+ score on immunohistochemistry (IHC).
• Have had at least one prior line of platinum-based therapy (in any setting).
• Was never previously received other ADC anti-tumor treatment. Cohort C: Metastatic or advanced solid tumor that are HER2 overexpression or mutation(Including urothelial cancer, colorectal adenocarcinoma and non-small cell lung cancer).

Exclusion Criteria:

• A treatment history of antibody-drug conjugate containing topoisomerase I inhibitors. Subjects with one of the following conditions prior to first dose, including, but not limiting to:A major operation or severe trauma history within 4 weeks; A history of chemotherapy, targeted therapy, anti-angiogenesis therapy, biotherapy, immunotherapy, radiotherapy or other anti-tumor therapy within 4 weeks; A history of endocrine therapy within 3 weeks; A history of autologous stem cell transplant within 3 months. Subjects with other malignant tumors in the past three years (not including cured non-melanoma skin basal cell carcinoma, cervical carcinoma in situ and other malignancies of low malignant potential that have been effectively controlled without treatment). Subjects with symptomatic CNS metastasis (for example, cerebral edema requiring glucocorticoids therapy, or progressive CNS metastasis), not including prior cerebral and meningeal metastasis that is confirmed stable with MRI and without systematic glucocorticoids therapy. Adverse reactions from the previous anti-tumor treatment have not yet recovered (>Grade 2 in NCI-CTCAE 5.0, with exception of alopecia and pigmentation or other adverse reactions judged no safety risk by the investigator). Subjects with clinically significant cardiovascular or cerebrovascular disease, including, but not limiting to: a medical history of symptomatic Congestive Heart Failure (CHF) (NYHA classes II-IV) or serious cardiac arrhythmia. a medical history of myocardial infarction or unstable angina within 6 months prior to screening; a QTc prolongation to > 450 millisecond (ms) in males and > 470 ms in females. Subjects with a medical history of interstitial lung disease (ILD)/pneumonia in need of glucocorticoids intervention,or with interstitial lung disease, or suspicious ILD by imaging detection at screening. Subjects with any uncontrolled active infection within 1 week prior to first dose. Subjects with concomitant disease potentially increasing toxicological risk. Known allergy to protein preparation or any protein drug with similar structure to FDA022-BB05. Subjects with a History of alcohol abuse or psychotropic/narcotic drug abuse; Pregnant or lactating women. Subjects with poor compliance, or not suitable for this study as determined by the investigator due to other reasons.
