Availability & biosimilar status
Biologics have no small-molecule generics; biosimilar competition is tracked in the FDA Purple Book.
Why the date isn’t exact: Biosimilar timing can change because patents may be challenged, settled, licensed, added or removed, and litigation can move the real date earlier or later.
🛈 What do these terms mean?
- Biologic patent
- A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
- Reference-product exclusivity
- A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
- Interchangeable exclusivity
- The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
- Earliest biosimilar (LOE)
- The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.
Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.
| Code | What it grants | Expires |
|---|---|---|
| RefProduct | Reference-product exclusivity (12-year, BPCIA) — no biosimilar can be licensed before this date | Mar 20, 2032 |

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Temporarily discontinue breastfeeding. A lactating woman should pump and discard breastmilk for at least 24 hours after technetium Tc 99m albumin aggregated injection administration. ( 8.2 )
8.1Pregnancy Risk Summary Available data from case reports on Technetium Tc 99m Albumin Aggregated Injection use are insufficient to evaluate drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproduction studies with technetium Tc 99m albumin aggregated have not been conducted. Although all radiopharmaceuticals have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose, the radiation exposure to the fetus from technetium Tc 99m albumin aggregated is expected to be low (less than 0.50 mGy) (see Data) .
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data Human Data No adverse fetal effects of radiation risks have been identified for diagnostic procedures involving less than 50 mGy, which represents less than 10 mGy fetal doses.
8.2Lactation Risk Summary Technetium-99m is present in breast milk. There are no data on the effects of technetium Tc 99m albumin aggregated on the breastfed infant or the effects on milk production. PULMOTECH MAA is used for imaging in infants with lung disease; exposure to technetium-99m via breastmilk is expected to be lower.
Based on clinical guidelines, exposure of technetium Tc 99m albumin aggregated to a breastfed infant may be minimized by advising a lactating woman to temporarily discontinue breastfeeding and to pump and discard breast milk for a minimum of at least 24 hours after administration of Technetium Tc 99m Albumin Aggregated Injection. The developmental and health benefits of breastfeeding should be considered along with a mother’s clinical need for PULMOTECH MAA, any potential adverse effects on the breastfed child from technetium Tc 99m albumin aggregated or from the underlying maternal condition.
8.4Pediatric Use PULMOTECH MAA, after radiolabeling with technetium Tc-99m, is indicated for lung scintigraphy as an adjunct in the evaluation of pulmonary perfusion in pediatric patients (birth to less than 17 years of age). The safety profile of Technetium Tc99m Albumin Aggregated Injection is similar to the one in adults. The safety and efficacy of PULMOTECH MAA have not been established for peritoneovenous shunt scintigraphy in pediatric patients.
8.5Geriatric Use No formal studies of PULMOTECH MAA in subjects aged 65 and over were performed to determine whether they respond differently from younger adult subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger adult patients. In general, dose selection for an elderly patient should be cautious; administering the low end of the particle dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Within 1 to 5 minutes of intravenous injection, over 90 percent of the technetium Tc 99m albumin aggregated particles are trapped in the arterioles and capillaries of the lung. Following intraperitoneal administration, technetium Tc 99m albumin aggregated mixes with the peritoneal fluid. Clearance from the peritoneal cavity varies from insignificant, which may occur with complete shunt blockage, to very rapid clearance with subsequent transfer into the systemic circulation when the shunt is patent.
12.2Pharm a codynamics The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of technetium Tc 99m albumin aggregated have not been fully characterized.
12.3Pharmacokinetics Distribution Organ selectivity is a direct result of particle size. At 10 micrometer and below, the albumin aggregates are taken up by the reticuloendothelial system. Above 10 to 15 micrometer, the aggregates become lodged in the lung capillaries by a purely mechanical process.
Distribution of aggregated albumin in the lungs is a function of regional pulmonary blood flow. The albumin aggregated is sufficiently fragile for the capillary micro-occlusion to be temporary. Erosion and fragmentation reduce the particle size, allowing passage of the aggregates through the pulmonary alveolar capillary bed.
The fragments then accumulate in the reticuloendothelial system. Elimination Elimination of the technetium Tc 99m albumin aggregated particles from the normal and abnormal human lungs occurs with a biological half-life of 10.8 hours (range 6.9 to 19 hours, n=5).

📋 Description ▾
11 DESCRIPTION
11.1Product Characteristics PULMOTECH MAA contains albumin aggregated obtained by fractionating material (source blood, plasma, serum, or placentas) from healthy human donors. The macroaggregated albumin (MAA) particles are formed by heat denaturation of stannous chloride treated albumin human under controlled conditions. Each vial contains 2,000,000 to 4,000,000 particles.
The particle size distribution of the aggregated albumin is such that not less than 90% are 10 to 90 micrometers in size. There are no aggregated albumin particles greater than 150 micrometers in size as determined by circular equivalents. PULMOTECH MAA (kit for the preparation of technetium Tc 99m albumin aggregated) injection provides a sterile, non-pyrogenic, non-radioactive, white lyophilized powder in a multiple-dose reaction vial, sealed under an atmosphere of nitrogen, for radiolabeling with Sodium Pertechnetate Tc 99m Injection to prepare Technetium Tc 99m Albumin Aggregated Injection, a radioactive diagnostic agent, for intravenous or intraperitoneal use.
Each reaction vial contains 2 mg of albumin aggregated, albumin human (7.1 mg), stannous chloride (0.1 mg minimum; 0.22 mg maximum stannous and stannic), sodium chloride (9 mg). Hydrochloric acid may have been added for pH adjustment. The pH is between 5 and 7.
It contains no preservatives.
11.2Physical Characteristics Technetium-99m decays by isomeric transition with a physical half-life of 6.02 hours. The principal photon that is useful for detection and imaging is listed in Table 4. Table 4 – Principal Radiation Emission Data for Technetium-99m Radiation Mean % per Disintegration Energy (keV) Gamma-2 89.07 140.5
11.3 External Radiation The specific gamma ray constant for technetium-99m is
0.78R/mCi-hr at 1 cm. The first half-value thickness of lead (Pb) for technetium-99m is 0.017 cm. A range of values for the relative attenuation of the radiation emitted by this radionuclide that results from interposition of various thicknesses of Pb is shown in Table 5.
For example, the use of 0.25 cm of Pb will decrease the external radiation exposure by a factor of about 1,000.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Adequate Hydration Advise patients to drink a sufficient amount of water to ensure adequate hydration before their study and urge them to drink and urinate as often as possible during the first hours following the administration of Technetium Tc 99m Albumin Aggregated Injection in order to reduce radiation exposure [see Dosage and Administration ( 2.2 )] . Pregnancy Advise pregnant women of the risk of fetal exposure to radiation doses if they undergo a radionucleotide procedure [see Use in Specific Populations ( 8.1 )].
Lactation Advise a lactating woman to temporally discontinue breastfeeding and to pump and discard breast milk for 24 hours after Technetium Tc 99m Albumin Aggregated Injection administration to minimize radiation exposure to a breastfed infant [see Use in Specific Populations ( 8.2 )].

🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Distribution Organ selectivity is a direct result of particle size. At 10 micrometer and below, the albumin aggregates are taken up by the reticuloendothelial system. Above 10 to 15 micrometer, the aggregates become lodged in the lung capillaries by a purely mechanical process.
Distribution of aggregated albumin in the lungs is a function of regional pulmonary blood flow. The albumin aggregated is sufficiently fragile for the capillary micro-occlusion to be temporary. Erosion and fragmentation reduce the particle size, allowing passage of the aggregates through the pulmonary alveolar capillary bed.
The fragments then accumulate in the reticuloendothelial system. Elimination Elimination of the technetium Tc 99m albumin aggregated particles from the normal and abnormal human lungs occurs with a biological half-life of 10.8 hours (range 6.9 to 19 hours, n=5).
