⏳ 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 | Jan 17, 2037 |

5 WARNINGS AND PRECAUTIONS Interstitial Lung Disease (ILD) and Pneumonitis: DATROWAY can cause severe and fatal cases of ILD/pneumonitis. Monitor for new or worsening signs and symptoms of ILD/pneumonitis. If ILD/pneumonitis is suspected, withhold DATROWAY and initiate corticosteroids.
Permanently discontinue DATROWAY in patients with confirmed Grade 2 or higher ILD/pneumonitis. ( 5.1 ) Ocular Adverse Reactions: DATROWAY can cause ocular adverse reactions including dry eye, keratitis, blepharitis, meibomian gland dysfunction, increased lacrimation, conjunctivitis, and blurred vision. Monitor patients for ocular adverse reactions during treatment with DATROWAY.
Advise patients to use preservative-free lubricating eye drops and to avoid using contact lenses during treatment with DATROWAY. Withhold, reduce the dose, or permanently discontinue DATROWAY based on the severity of ocular adverse reactions. Refer patients to an eye care professional for any new or worsening ocular signs and symptoms.
( 2.3 , 2.4 , 5.2 ) Stomatitis/Oral Mucositis: DATROWAY can cause stomatitis, including mouth ulcers and oral mucositis. Advise patients to use a steroid-containing mouthwash when starting treatment and to hold ice chips or ice water in mouth during the infusion of DATROWAY. Withhold, reduce the dose, or permanently discontinue DATROWAY based on severity.
( 2.3 , 2.4 , 5.3 ) Embryo-Fetal Toxicity : DATROWAY can cause fetal harm. Advise patients of potential risk to a fetus and to use effective contraception. ( 5.4 , 8.1 , 8.3 )
5.1Interstitial Lung Disease/Pneumonitis DATROWAY can cause severe, life-threatening, or fatal interstitial lung disease (ILD) or pneumonitis. Locally Advanced or Metastatic NSCLC In the pooled safety population of 484 patients with NSCLC from TROPION-Lung01, TROPION-Lung05, and TROPION-PanTumor01 [see Adverse Reactions (6.1) ], ILD/pneumonitis occurred in 7% of patients treated with DATROWAY, including 0.6% of patients with Grade 3 and 0.4% with Grade 4. There were 8 (1.7%) fatal cases.
The median time to first onset for ILD was 1.4 months (range: 0.2 months to 9 months). Eleven patients (2.3%) had DATROWAY withheld and 20 patients (4.1%) permanently discontinued DATROWAY due to ILD/pneumonitis. Systemic corticosteroids were required in 79% (26/33) of patients with ILD/pneumonitis.
ILD/pneumonitis resolved in 45% of patients. Unresectable or Metastatic Breast Cancer In the pooled safety population of 841 patients with breast cancer from TROPION-Breast01, TROPION-Breast02, TROPION-PanTumor01 and TROPION-PanTumor02 [see Adverse Reactions (6.1) ], ILD/pneumonitis occurred in 3.0% of patients treated with DATROWAY, including 0.4% of patients with Grade 3. There were two fatal cases (0.2%).
The median time to first onset for ILD was 5.3 months (range: 1.1 months to 19.3 months) and with a median duration of 1.2 months (range: 0.3 to 5.2). Eight patients (1.0%) had DATROWAY withheld and 10 patients (1.2%) permanently discontinued DATROWAY due to ILD/pneumonitis. Systemic corticosteroids were required in 64% (16/25) of patients with ILD/pneumonitis.
ILD/pneumonitis resolved in 40% of patients. Patients were excluded from clinical studies for a history of ILD/pneumonitis requiring treatment with steroids or for ongoing ILD/pneumonitis. Monitor patients for new or worsening respiratory symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever) during treatment with DATROWAY.
For asymptomatic (Grade 1) ILD/pneumonitis, consider corticosteroid treatment (e.g., ≥0.5 mg/kg/day prednisolone or equivalent). For symptomatic ILD/pneumonitis (Grade 2 or greater), promptly initiate systemic corticosteroid treatment (e.g., ≥1 mg/kg/day prednisolone or equivalent) and continue for at least 14 days followed by gradual taper for at least 4 weeks. Withhold DATROWAY in patients with suspected ILD/pneumonitis and permanently discontinue DATROWAY if ≥Grade 2 ILD/pneumonitis is confirmed [see Dosage and Administration (2.4) ].

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed. ( 8.2 ) Infertility: May impair fertility in males and females. ( 8.3 )
8.1Pregnancy Risk Summary Based on its mechanism of action, DATROWAY can cause embryo-fetal harm when administered to a pregnant woman because the topoisomerase inhibitor component of DATROWAY, DXd, is genotoxic and affects actively dividing cells [see Clinical Pharmacology (12.1) , Nonclinical Toxicology (13.1) ] . There are no available data on the use of DATROWAY in pregnant women to inform a drug-associated risk. Advise patients of the potential risks to a fetus.
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 Animal Data There were no animal reproductive or developmental toxicity studies conducted with datopotamab deruxtecan-dlnk.
8.2Lactation Risk Summary There are no data regarding the presence of datopotamab deruxtecan-dlnk or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with DATROWAY and for 1 month after the last dose.
8.3Females and Males of Reproductive Potential DATROWAY can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ]. Pregnancy Testing Verify pregnancy status of females of reproductive potential prior to initiation of DATROWAY. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with DATROWAY and for 7 months after the last dose.
Males Because of the potential for genotoxicity, advise male patients with female partners of reproductive potential to use effective contraception during treatment with DATROWAY and for 4 months after the last dose [see Nonclinical Toxicology (13.1) ] . Infertility Based on findings in animal toxicity studies, DATROWAY may impair male and female reproductive function and fertility.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Datopotamab deruxtecan-dlnk, is a Trop-2-directed antibody-drug conjugate. The antibody is a humanized anti-Trop2 IgG1. The small molecule, DXd, is a topoisomerase I inhibitor attached to the antibody by a cleavable linker.
Following binding to Trop-2 on cells, including tumor cells, datopotamab deruxtecan-dlnk undergoes internalization and intracellular linker cleavage by lysosomal enzymes. Upon release, the membrane-permeable DXd causes DNA damage and apoptotic cell death. Datopotamab deruxtecan-dlnk had anti-tumor activity in mouse models of lung cancer including EGFR-mutated and breast cancer.
12.2Pharmacodynamics Datopotamab deruxtecan-dlnk time course of pharmacodynamic response is unknown. Exposure-Response Relationships A relationship between datopotamab deruxtecan-dlnk exposure and efficacy has not been fully characterized in breast cancer or EGFR-mutated NSCLC. In the pooled population of NSCLC (including EGFR-mutated NSCLC) and breast cancer patients, higher datopotamab deruxtecan-dlnk systemic exposure is associated with a higher incidence rate of serious adverse reactions, dosage interruptions, dose reductions, stomatitis/oral mucositis, ocular adverse reactions, and Grade ≥3 adverse reactions.
Cardiac Electrophysiology At datopotamab deruxtecan-dlnk doses up to 10 mg/kg (1.7 times the recommended dose), mean increase in the QTc interval >20 ms was not observed.
12.3Pharmacokinetics Datopotamab deruxtecan-dlnk and DXd exposure after the first dose of the approved recommended dosage of cycle 1 are provided in Table 10. Datopotamab deruxtecan-dlnk and released DXd maximum concentration (C max ) and area under the time-concentration curve (AUC) increases proportionally over a dose range of 4 mg/kg to 10 mg/kg (approximately 0.7 to 1.7 times the approved recommended dosage). No clinically significant datopotamab deruxtecan-dlnk accumulation occurs between cycles 1 and 3.
Table 10: Datopotamab Deruxtecan-dlnk and DXd Mean (CV%) Exposure After the First Dose PK Parameter Datopotamab deruxtecan-dlnk DXd Abbreviations: C max =maximum concentration; AUC =area under the time-concentration curve C max 154 µg/mL (20%) 2.8 ng/mL (58%) AUC 671 µg*day/mL (31%) 18 ng*day/mL (43%) Distribution Datopotamab deruxtecan-dlnk mean steady state volume of distribution is 3.5 (23%) L. DXd plasma protein binding is approximately 98% and the blood-to-plasma concentration ratio is 0.6 in vitro. Elimination The datopotamab deruxtecan-dlnk median elimination half-life (t 1/2 ) is 4.8 days (1.0, 8.2) and the released DXd median apparent t 1/2 is approximately 5.5 days (3.2, 8.8).
The estimated datopotamab deruxtecan-dlnk clearance is 0.6 (31.5%) L/day. Metabolism Datopotamab deruxtecan-dlnk undergoes intracellular cleavage by lysosomal enzymes to release DXd . The humanized Trop-2 IgG1 monoclonal antibody is expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG.
In vitro, DXd is primarily metabolized by CYP3A4. Specific Populations The mean volume of distribution and clearance of datopotamab deruxtecan-dlnk and DXd increase with increasing body weight (36 kg to 156 kg). No clinically significant differences in the pharmacokinetics of datopotamab deruxtecan-dlnk or DXd were observed based on age (26 to 86 years), race (Asian, White, or Black), sex, mild hepatic impairment (total bilirubin ≤ULN and any AST >ULN or total bilirubin >1 to 1.5 times ULN and any AST), or CLcr 30 to <90 mL/min.
The pharmacokinetics of datopotamab deruxtecan-dlnk in patients with moderate hepatic impairment (total bilirubin >1.5 to 3 times ULN and any AST) was comparable to patients with normal hepatic function (total bilirubin and AST ≤ULN). The steady state average DXd AUC was 2.5-fold higher in patients with moderate hepatic impairment compared to patients with normal hepatic function. The effect of severe hepatic impairment (total bilirubin >3 times…
🧬 Mechanism of Action ▾
12.1Mechanism of Action Datopotamab deruxtecan-dlnk, is a Trop-2-directed antibody-drug conjugate. The antibody is a humanized anti-Trop2 IgG1. The small molecule, DXd, is a topoisomerase I inhibitor attached to the antibody by a cleavable linker.
Following binding to Trop-2 on cells, including tumor cells, datopotamab deruxtecan-dlnk undergoes internalization and intracellular linker cleavage by lysosomal enzymes. Upon release, the membrane-permeable DXd causes DNA damage and apoptotic cell death. Datopotamab deruxtecan-dlnk had anti-tumor activity in mouse models of lung cancer including EGFR-mutated and breast cancer.

📋 Description ▾
11 DESCRIPTION Datopotamab deruxtecan-dlnk is a Trop-2-directed antibody and topoisomerase inhibitor conjugate. Datopotamab deruxtecan-dlnk is an antibody-drug conjugate (ADC) composed of three components: 1) a humanized anti-Trop-2 IgG1 monoclonal antibody (mAb), covalently linked to 2) a topoisomerase I inhibitor, via 3) a tetrapeptide-based cleavable linker. Deruxtecan is composed of a protease-cleavable maleimide tetrapeptide linker and the topoisomerase inhibitor, DXd, which is an exatecan derivative.
The antibody is produced in Chinese hamster ovary cells by recombinant DNA technology, and the topoisomerase inhibitor and linker are produced by chemical synthesis. Approximately 4 molecules of deruxtecan are attached to each antibody molecule. Datopotamab deruxtecan-dlnk has the following structure: DATROWAY (datopotamab deruxtecan-dlnk) for injection is a sterile, white to yellowish white, preservative-free lyophilized powder in single-dose vials.
Each vial delivers 100 mg of datopotamab deruxtecan-dlnk, L-histidine (3.88 mg), L-histidine hydrochloride monohydrate (5.25 mg), polysorbate 80 (1.50 mg), and sucrose (450 mg). Following reconstitution with 5 mL of Sterile Water for Injection, USP, the resulting concentration of datopotamab deruxtecan-dlnk is 20 mg/mL with a pH of 6.0. The resulting solution is administered by intravenous infusion following dilution.
