简要总结
Multicenter Phase 2 study of 212Pb-DOTAMTATE enrolling adult subjects with positive somatostatin positive neuroendocrine tumors with either no prior history of peptide receptor radionuclide therapy (PRRT naive) or prior history of peptide receptor radionuclide therapy (Previous PRRT)
详细描述
In this open-label, multicenter, single-arm Phase 2 study, adult subjects with histologically confirmed NETs and positive somatostatin analog imaging, with either no prior PRRT (PRRT naive) or prior history of peptide receptor radionuclide therapy (previous PRRT) will be enrolled to receive 212Pb-DOTAMTATE 67.6 μCi/kg dose per cycle

入选标准
- •Male or female ≥18 years old with unresectable or metastatic histologically confirmed NET
- •Subjects must have received and progressed following somatostatin analog administration
- •For PRRT naive subjects, documented progression of disease following previous therapy within 12 months prior to enrollment and the presence of at least 1 site of measurable disease per RECIST 1.1
- •Subjects who previously received PRRT must have documented progression of disease and at least 1 site of measurable disease per RECIST 1.1 after receiving up to 4 doses (≤ 880 mCi) of 177Lu-DOTATATE/DOTATOC and received their last dose at least 6 months prior to Day 1
- •Confirmed presence of somatostatin receptors on all lesions including the non-target and measurable lesions documented by CT/MRI scans, based on positive 68Ga-DOTATATE (NETSPOT®), 64Cu-DOTATATE (Detectnet™), or other Food and Drug Administration (FDA) approved SSTR PET/CT imaging within 6 weeks prior to enrollment. Follow up imaging should be performed with the same agent or modality used at baseline;
- •Target lesions must be positive (greater than grade 2 uptake Krenning Score) or must have a standardized uptake value of more than the normal liver background.
- •Lytic bone lesions, with an identifiable soft tissue component, evaluated by CT or MRI, can also be considered measurable lesions if the soft tissue component otherwise meets the definition of measurability according to RECIST 1.
- •Eastern Cooperative Oncology Group (ECOG) status 0-2;
- •Life expectancy of at least 12 weeks in the opinion of the investigator at the time of screening;
- •Sufficient bone marrow capacity and organ function in the recent blood tests within 3 weeks prior to Day 1, as defined by:
- •White blood cell (WBC) ≥2,500/ mm3;
- •Absolute neutrophil count (ANC) ≥1000/mm3;
- •Platelets ≥100,000/mm3;
- •Hemoglobin (HgB) ≥9.0 g/dL;
- •Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) ≤3 X upper limit of normal (ULN);
- •Total Bilirubin: ≤2 X ULN;
- •Serum creatinine ≤1.7 mg/dL for PRRT naïve subjects; ≤ ULN for previous PRRT subjects;
- •Serum albumin ≥3.0 g/L; if lower than 3.0 g/L requires normal range prothrombin time (PT) and international normalized ratio (INR), and
- •Be willing to practice the following medically acceptable methods of birth control (both women of childbearing potential (WOCBP) and men who have partners of childbearing potential) from the Screening Visit through 3 months after the final administration 212Pb-DOTAMTATE
排除标准
- •Prior whole-body radiotherapy or PRRT using 177Lu/90Y/111In-DOTATATE/ DOTATOC or Targeted Alpha Therapy (TAT).
- •For subjects who previously received PRRT, prior treatment with: Prior treatment with 90Y- DOTATATE/ DOTATOC, 225Ac-DOTATATE/DOTATOC, and/or 111In-DOTATATE/ DOTATOC
- •Prior regional hepatic radionuclide therapy within 4 months prior to enrollment or prior nonradioactive regional hepatic therapy within 6 months prior to enrollment.
- •Known hypersensitivity to somatostatin analogues, Amino Acid infusion, or 212Pb-DOTAMTATE;
- •Therapeutic use of any somatostatin analogue, including Sandostatin® LAR (within 28 days) and Sandostatin® (within 1 day) prior to Cycle 1 Day 1;
- •History of myelodysplastic syndrome (MDS);
- •Female subjects who are pregnant or lactating;
- •Indication for surgical lesion removal with curative potential;
- •Known brain metastases, unless these metastases have been treated and/or stable for 6 months prior to enrollment;
- •Experimental cancer treatments or other investigational therapies within 6 weeks or five half-lives of the investigational medication prior to Day 1;
- •Uncontrolled congestive heart failure (NYHA II, III, IV);
- •Uncontrolled diabetes mellitus as defined by a hemoglobin A1C >10.0;
- •Evidence of renal obstruction based on Tc-99m DTPA or TER for MAG3 renal scintigraphy or renal ultrasound.
- •Known or active human immunodeficiency virus (HIV) or hepatitis B or C virus unless cured;
- •Known or suspected active drug or alcohol abuse;
- •Participation in other interventional clinical studies within 30 days prior to Day 1;
- •Other known co-existing malignancies except non-melanoma skin cancer and carcinoma in situ of the uterine cervix, unless definitively treated and proven no evidence of recurrence for 5 years;
- •Any somatic or psychiatric disease/condition or abnormal laboratory test that in the opinion of the investigator, may interfere with the objectives and assessments of the study; or
- •Unable to comply with the requirements of the study protocol or be unsuitable for the study for any reason, in the opinion of the investigator.
