Life expectancy of at least 12 weeks.
Histologically confirmed diagnosis of SSTR (+) NET, unresectable or metastatic.
Measurable disease per RECIST 1.1 on CT/MRI scans, defined as at least 1 lesion with ≥ 1 cm in longest diameter (LD) (lymph nodes along short axis).
Appropriate diagnostic imaging studies, at the discretion of the PI including but not limited to CT, MRI, 18F-FDG PET/CT, NAF PET/CT bone scan, ultrasound, etc. of the tumor region or suspected area within the 4 weeks of dosing day.
SSTR(+) disease, as evidenced by available FDA approved SSTR imaging (SRI) within 4 weeks prior to the first cycle.
All FDA-approved therapies for which the subject is eligible have been exhausted.
Recent blood test results (within 2 weeks pre-dose) as follows: Sufficient bone marrow capacity as defined by white blood cell (WBC) ≥2,500/µl and WBC ≥2,000/µl for subsequent cycles; platelets ≥ 100,000/µl for the first treatment and ≥75,000 for the subsequent therapies, hemoglobin (HgB) ≥8.9 g/dl for the first treatment and 8.0 g/dl for the subsequent therapies, ANC ≥1,500/µl for the first treatment and ≥1,000/µl; for the subsequent therapies; ALT, AST values ≤3 times upper limit of normal (ULN); Bilirubin: ≤3 times ULN; Serum creatinine ≤150 µmol/liter or 1.7 mg/dl; Negative pregnancy test in women capable of child-bearing within 48 hours of administration; Serum albumin > 3.0 g/L (<3.0 g/L may be acceptable at the discretion of PI, if PT, PTT, and INR are within normal range)

Exclusion Criteria:

Known hypersensitivity to 68Gallium, Octreotate, or any of the excipients of 68Ga-DOTATATE, AA infusion or AlphaMedix™.
Therapeutic use of any somatostatin analogue, including Sandostatin® LAR (within 28 days) and Sandostatin® (within 1 day) prior to administration of investigational drug.
Subjects with unusual hematological parameters, including an increased mean corpuscular volume (MCV) (>100,000), and especially in those who had previous chemotherapy, the advice of a hematologist should be sought for adequate further work-up to rule out myelodysplastic syndrome (MDS).
Any subject who is taking concomitant medications that decrease renal function (such as aminoglycoside antibiotics).
Female subjects who are pregnant, lactating or women of childbearing potential not willing to practice effective contraceptive techniques during the study period and for 8 weeks post-injection or male subjects who have female partners of childbearing potential not willing to practice abstinence or effective contraception, during the study period and for 8 weeks post-injection.

Carcinoid heart disease: Prior history of torsade de pointe, or congenital long QT syndrome; Conditions with screening ECG repolarization difficult to interpret, or showing significant abnormalities. This includes, but is not limited to: high degree AV block, pacemaker, atrial fibrillation or flutter; QTcF interval > 480 msec on screening ECG; Significant hypokalemia at screening (Potassium <3.5 mMol/L); Significant hypomagnesemia at screening (Mg++ <0.7 mMol/L)
