Breast Cancer Clinical Trial
A Study to Evaluate the Safety, Tolerability, and Efficacy of MORAb-202 (Herein Referred to as Farletuzumab Ecteribulin), a Folate Receptor Alpha (FRα)-Targeting Antibody-drug Conjugate (ADC) in Participants With Selected Tumor Types
The primary objectives of the study are: (1) in the dose-escalation part: to evaluate safety and tolerability and to determine the recommended Phase 2 dose (RP2D) of farletuzumab ecteribulin in participants with selected tumor types (ovarian cancer [OC], endometrial cancer [EC], non-small cell lung carcinoma [NSCLC], triple-negative breast cancer [TNBC]), and (2) in dose-confirmation part: to evaluate preliminary efficacy measured by objective response rate (ORR) of farletuzumab ecteribulin in participants with OC and EC at selected doses and to further evaluate the safety and tolerability of farletuzumab ecteribulin.
Aged >=18 years
For Dose-Escalation: Females (TNBC, EC and OC) or males/females (NSCLC, adenocarcinoma). Participants with the following disease characteristics:
Participants with the following tumor types, each as a separate arm:
TNBC: Histologically confirmed diagnosis of metastatic TNBC (that is, estrogen receptor (ER) negative/progesterone receptor negative/ human epidermal growth factor receptor 2 (HER2) negative (defined as immunohistochemistry (IHC) less than (<) 2 plus (+) or fluorescence in situ hybridization (FISH) negative) breast cancer). Previously treated with at least one line of systemic anticancer therapy (cytotoxic or targeted anticancer agents) in the metastatic setting.
NSCLC adenocarcinoma: Histologically or cytologically confirmed metastatic NSCLC adenocarcinoma: participants who have failed previous treatment for metastatic disease, are not indicated or failed epidermal growth factor receptor (EGFR)-, Anaplastic lymphoma kinase (ALK) -, B-Raf proto-oncogene (BRAF) - or c-ros oncogene 1 (ROS1) - targeted therapy, and for whom no alternative standard therapy exists.
EC: Histologically confirmed diagnosis of advanced, recurrent or metastatic EC. Relapsed or failure of at least one platinum-based regimen or one immunotherapy-based regimen.
OC or primary peritoneal cancer or fallopian tube cancer: Histologically confirmed diagnosis of high grade serous epithelial ovarian cancer or primary peritoneal cancer or fallopian tube cancer.
Participants must have:
platinum-resistant disease (defined as progression within 6 months after the last dose of at least 4 cycles of the last platinum containing chemotherapy regimen)
received up to 4 lines of systemic therapy post development of platinum resistance.
Ovarian cancer or primary peritoneal cancer or fallopian tube cancer:
For participant with 1 line of platinum-containing therapy: RECIST version 1.1 progression greater than (>) 1 month and less than or equal to (<=) 6 months after the last dose of the first platinum-containing chemotherapy regimen (of at least 4 cycles)
For participant with 2-3 lines of platinum-containing therapy: RECIST version 1.1 progression during or within 6 months after the last dose of the 2nd or 3rd platinum-containing chemotherapy regimen.
Have received up to 3 prior lines of systemic therapy and for whom single-agent therapy is appropriate as the next line of therapy. Participants may have been treated with up to one line of therapy subsequent to determination of platinum-resistance.
Neoadjuvant plus/minus (±) adjuvant will be considered 1 line of therapy.
Maintenance therapy (example, bevacizumab, PARP inhibitors) will be considered part of the preceding line of therapy (will not be counted as an independent line of therapy).
Hormonal therapy will be counted as a separate line of therapy unless it was given as maintenance.
Therapy changed due to toxicity in the absence of progression will be considered part of the same line.
Participants must have histologically confirmed diagnosis of advanced, recurrent, or metastatic EC. All histologic (including carcinosarcoma [no more than one participant at any dose level]) and molecular subtypes will be included. Participants may have been treated with an Immune Checkpoint Inhibitor (ICI) containing regimen (or be ineligible for ICI treatment) and must have had no more than 2 prior regimens (not including adjuvant therapy if progression or recurrent/metastatic disease occurred more than 6 months after the completion of the last cycle of adjuvant therapy).
Note: There is no restriction regarding prior hormonal therapy.
