Micropore Filter Testing and Drug Product /Filter Compatibility
(Bubble Point Test).
Approved by: _____________________________Initials________ Date:____________
Victor W Pike, Ph.D., Chief, PET Radiopharmaceutical Sciences, NIMH
• Filter-Integrity test. The integrity of the Millex-MP sterile filter that was used for sterile filtration of [18F]Fallypride for Injection is tested by the following method. The knob on the pressure regulator that is hooked to the house compressed air gas supply is turned counter clockwise so as to minimize outlet pressure. The filter assembly is removed from the sterile dose vial and placed on the male luer-lock fitting of the pressure-regulated 1/8” Teflon line. A disposable needle (1.5 inch 22 gauge) is placed on the male luer fitting of the Millex-MP filter. A portion of this needle is submerged in a test tube (12 x 50 mm) containing about 3 mL of HPLC grade water. The knob of the pressure regulator is slowly turned clockwise and the pressure gauge is monitored visually. The pressure is brought to 45 p.s.i. If there is an absence of a steady stream of bubbles in the test tube when the pressure gauge reads 45 p.s.i., then the filter passes the test. The result of the filter test is recorded on the batch record and in the summary section of the quality control test form.

Victor W Pike, Ph.D., Chief, NIMH, PET Radiopharmaceutical Sciences
Procedure
1. Set the analytical HPLC system (Beckman Coulter) in working conditions and maintain flow for 40 min for column equilibration.
|HPLC system conditions: |
|Column: Prodigy ODS (3) (100 μm; 4.6 x 250 mm; Cat. # 00G-4244-E0; Phenomenex) |
|Mobile phase: Acetonitrile-5 mM ammonium formate (50: 50 v/v) |
|Flow rate: 1.0 mL/min. |
|UV Wavelength: 305 nm |
2. Download the analytical method “Fally_analysis_secondSys” or “Fally_analysis_firstSys” from method box in Beckman software.
3. Validation of HPLC system
• Inject standard fallypride (20−40 µg), which is already prepared according to SOP # QA301, and record the exactly mass (ng) injected and retention time of fallypride standard.
• Calculate the mass of fallypride corresponding to the peak of fallypride in HPLC chromatography, based on the standard curve of fallypride.
• Compare the mass of the fallypride injected with the mass calculated, the difference should be equal or less then 10%. (Recovery ≤ 90%)
4. HPLC system cleaning
• Inject solvent (100 µL) once or twice to clean the system in 10-15 min after standard fallypride running. Check that only the solvent front peak should shows in the chromatography.
• Inject 10% ethanol in saline (100 µL). Check that only the solvent front and saline peaks show in the chromatography.
5. QC of final product: [18F]Fallypride for Injection
• Measure the radioactivity of sample of final product of [18F]Fallypride for Injection (50−150 μL) before and after injection onto the HPLC system in hot-cell 5, and record the number in QC record sheet. Calculate the activity injected (decay correlation)
• Inject the sample of [18F]Fallypride for Injection (50−150 μL depending on the radioactivity concentration of formula).
• Check the retention time (Rt) of the standard and the [18F]fallypride for radiochemical identity (the difference of Rt < I min)
• Calculate the mass corresponding the UV area of the [18F]fallypride peak in the chromatograph, based on the standard curve of fallypride.
• Calculate the specific radioactivity according to the radioactivity injected and the mass calculated at HPLC injection time.
• Calculate the specific activity at the time of HPLC injection, EOS and EOB (decay correction).
• Calculate the mass (μg) of whole formula based on the radioactivity of final formula, which recorded on master batch Sheet Page 4, and the specific activity at EOS.
• Record the chemical purity, radiochemical purity, the concentration of the final formula and the expired time.
6. Post-analysis HPLC system and column cleaning: to run the HPLC system for 40−50 min with the solvent (acetonitrile-HPLC water; 70: 30 v/v) for cleaning the HPLC system and the column. Turn off the HPLC system and software.

Sterility Test
Approved by: _____________________________Initials________ Date: _____________
Victor W Pike, Ph.D., Chief, NIMH, PET Radiopharmaceutical Sciences
Notes.
1. Routine sterility tests will be run by the Clinical Microbiology laboratory of the Department of Laboratory Medicine at NIH, through a FDA approved procedure.
2. The radiochemistry lab will provide a sample of each formulation (in its original filtration vial), 24 h after its preparation or when no traces of radioactivity are detected anymore (ten or more half life periods).
3. Before their transportation to the testing laboratory, the samples will be stored in the refrigerator until decay.
4. A log book will be kept in the radiochemistry lab indicating the date the samples were transported, their lot number and the date and results of the test (readings at 7 and 14 d should be indicated).

SOP # QA307
Pyrogen Test (LAL Bacterial Endotoxin Test). Simplified Procedure
Approved by: _____________________________Initials________ Date: _____________
Victor W Pike, Ph.D., Chief, NIMH, PET Radiopharmaceutical Sciences
Materials
LAL test kit vials (e.g., Endosafe Inc., Charleston, SC or Cape Cod Associates, Falmouth MA)
Two vials 0.125 EU/mL(one for test sample, one for negative test)
One positive vial (5 EU/mL)
Sterile saline solution (from the same vial used for the final formulation)
Pyrogen-free test tubes (if not provided with kit)
Micropippets and tips (50 µL, 100 µL, 500 µL)
Tuberculin syringes (0.5 mL, 1 mL)
Incubator, 37°C
LAL Test Procedure: See “RADIOPHARMACY TEST RESULTS” form
Simplified Test Procedure ( it may not be used as a procedure of LAL test.)
a) From the final formulation in saline, take 50 µLand add to the test sample tube. To the same LAL tube add 150 µLof saline (for a total of 200 µL).
b) To the negative test tube add 200 µL saline only.
c) To the positive test tube add also 200 µL saline.
d) Incubate all vials at 37 °C for 1 h. Remove the test vials at 20 min and in one smooth careful motion, invert each tube (without totally disturbing the gel) and note gel formation.
e) Continue incubation of the vials for the full 60 min. Again in one smooth motion, invert each vial and note gel formation.
f) The test sensitivity equals the concentration of the test vial multiplied by the dilution factor. If the test sample does not gel, report the result as less than the test sensitivity. If the test sample gels, report as greater than or equal to the test sensitivity.
Note. The results at 20 min will allow release of the formulation for injection and the 60 min samples will confirm the results.
