Datroway (Datopotamab Deruxtecan): MOA, Approvals & India

Reviewed and updated: 12 August 2026. Regulatory status, indications and Indian commercial-availability status change frequently. Verify against the primary sources in the References before making any clinical, procurement or regulatory decision.

In brief

Datopotamab deruxtecan is a TROP2-directed antibody-drug conjugate sold as Datroway in the US, EU and Japan, and approved in India under a different brand name — Datverzo. It now holds three US indications: HR-positive/HER2-negative breast cancer (17 Jan 2025)[1], EGFR-mutated NSCLC by accelerated approval (23 Jun 2025)[2], and first-line triple-negative breast cancer (22 May 2026)[3]. The EU followed on the TNBC indication on 31 July 2026[9].

In India, CDSCO granted AstraZeneca Pharma India Limited permission to import, sell and distribute the product on 17 December 2025, for the breast-cancer indication only[5]. No commercial launch date or Indian list price has been publicly announced. Any figure you find quoted as a “Datroway price in India” is an importer’s indicative quotation, not a published Indian price.

Availability, access and price in India

This is the question most searches arrive with, so here is the verifiable position rather than a guess.

  • Regulatory status. On 17 December 2025 CDSCO granted AstraZeneca Pharma India Limited permission to import for sale and distribution of datopotamab deruxtecan powder for concentrate for solution for infusion, 100 mg (r-DNA origin), under the brand name Datverzo, as a new drug in India[5]. This is AstraZeneca’s second ADC approval in India, after trastuzumab deruxtecan[5].
  • Approved Indian indication. Adults with unresectable or metastatic HR-positive, HER2-negative (IHC 0, IHC 1+ or IHC 2+/ISH-) breast cancer who have received prior endocrine-based therapy and chemotherapy for unresectable or metastatic disease[5][6]. It does not extend to the EGFR-mutated NSCLC or triple-negative indications later approved in the US.
  • Launch and price. AstraZeneca Pharma India’s own announcement said information on the potential Indian launch timeline would follow once all necessary approvals were obtained[5]. As of 12 August 2026 no launch date and no list price have been publicly announced.
On the prices you will find quoted online

Searches for a Datroway or Datverzo price in India return quotations from named-patient supply intermediaries. Those are commercial quotations for an import transaction — they are not a published Indian MRP, they are not NPPA-notified, and they vary by consignment. We have not found a verified Indian list price and will not publish an invented one. Unverified pricing on an oncology biologic is a patient-safety and credibility risk, not a convenience.

General regulatory description · not procurement or clinical advice

Vial, reconstitution and administration

This is the part of the label that hospital pharmacy, procurement and QA teams actually need, and it is almost never reproduced in drug-name search results. Everything below is FDA-label content[4], reported as label information — not as a direction to any individual patient.

Do not reconstitute or dilute with sodium chloride

The label explicitly directs that Sodium Chloride Injection, USP must not be used. Reconstitution is with Sterile Water for Injection; dilution is into 5% Dextrose Injection. This is a genuine preparation error risk in a unit that defaults to normal saline for infusions[4].

Reconstituting the 100 mg vial

  • Supplied as a white to yellowish-white preservative-free lyophilised powder, 100 mg in a single-dose vial (NDC 65597-801-01)[4].
  • Slowly inject 5 mL Sterile Water for Injection per vial using a sterile syringe, giving a final concentration of 20 mg/mL.
  • Swirl gently until fully dissolved. Do not shake.
  • More than one vial is usually needed — calculate dose, total reconstituted volume and vial count before starting.
  • Reconstituted solution should be clear and colourless to light yellow. Discard if cloudy, discoloured or containing visible particles.
  • If not used immediately, refrigerate in the original vial at 2 °C to 8 °C for up to 24 hours from reconstitution, protected from light. Do not freeze. No preservative is present, so discard after 24 hours.

Each vial also contains L-histidine 3.88 mg, L-histidine hydrochloride monohydrate 5.25 mg, polysorbate 80 1.50 mg and sucrose 450 mg; the reconstituted solution has a pH of 6.0[4].

Mechanism of action, in the detail the abstract leaves out

Datopotamab deruxtecan-dlnk is a Trop2-directed antibody and topoisomerase inhibitor conjugate built from three covalently linked components[4]:

  1. Datopotamab — a humanised anti-Trop2 IgG1 monoclonal antibody. TROP2 is a transmembrane glycoprotein broadly expressed across epithelial tumour types, including HR-positive/HER2-negative and triple-negative breast cancer.
  2. A protease-cleavable maleimide tetrapeptide linker, designed to stay intact in systemic circulation and to be cleaved only after internalisation.
  3. DXd — a topoisomerase I inhibitor derived from exatecan. Approximately four DXd molecules are attached per antibody (drug-to-antibody ratio, DAR, of about 4)[4].

After the antibody binds Trop2, the conjugate is internalised and lysosomal enzymes cleave the linker intracellularly. The released, membrane-permeable DXd inhibits topoisomerase I, causing DNA damage and apoptotic cell death[4]. Because DXd crosses membranes, it can diffuse into adjacent tumour cells — including cells expressing little or no TROP2 — producing the “bystander” effect characteristic of this ADC class.

Two numbers worth carrying into any ADC comparison

The DAR of roughly 4, and the cleavable tetrapeptide linker, are what separate this molecule from the other marketed TROP2 ADC, sacituzumab govitecan, which carries an SN-38 payload on a hydrolysable linker. Same target, different payload chemistry and different release kinetics — which is why cross-trial safety comparison between the two is not straightforward.

Pharmacokinetically, the ADC has a median elimination half-life of about 4.8 days and released DXd about 5.5 days; DXd is roughly 98% plasma protein bound and is metabolised primarily by CYP3A4. Steady-state DXd exposure was 2.4-fold higher in patients with moderate hepatic impairment than in those with normal hepatic function[4]. The molecule is produced in Chinese hamster ovary cells by recombinant DNA technology; linker and payload are made by chemical synthesis and conjugated during manufacture[4].

Regulatory approval timeline

  • 17 Jan 2025 · FDA Approval — HR+/HER2-negative breast cancer

    First approval for the molecule, on TROPION-Breast01. Adults with unresectable or metastatic disease after prior endocrine-based therapy and chemotherapy[1].

  • 31 Jan 2025 · EMA CHMP Positive opinion — HR+/HER2-negative breast cancer

    A CHMP opinion is a recommendation, not the authorisation[7].

  • 8 Apr 2025 · European Commission EU marketing authorisation granted

    The step that actually permits marketing across member states — roughly ten weeks after the CHMP opinion[10].

  • 23 Jun 2025 · FDA Accelerated approval — EGFR-mutated NSCLC

    Pooled subgroup of 114 patients across TROPION-Lung05 and TROPION-Lung01; ORR 45% (95% CI 35, 54), median duration of response 6.5 months (95% CI 4.2, 8.4). Granted priority review and breakthrough therapy designation; continued approval may be contingent on confirmatory data[2].

  • 17 Dec 2025 · CDSCO India Import, sale and distribution permitted as Datverzo

    Granted to AstraZeneca Pharma India Limited for the HR-positive/HER2-negative breast-cancer indication only. Launch timeline and price not announced[5][6].

  • 22 May 2026 · FDA Approval — first-line triple-negative breast cancer

    PD-1/PD-L1-ineligible patients, on TROPION-Breast02. Reviewed under Project Orbis with the Australian TGA, Brazil’s ANVISA, Health Canada, Singapore’s HSA and Swissmedic[3].

  • 23 Jun 2026 · EMA CHMP Positive opinion on the TNBC indication

    CHMP adopted a positive opinion recommending a variation to add first-line metastatic TNBC in PD-1/PD-L1-ineligible patients[8].

  • 31 Jul 2026 · European Commission EU approval — first-line metastatic TNBC

    The second EU breast-cancer indication, and the first TROP2-directed therapy in this setting with a demonstrated overall-survival benefit[9].

A distinction regulatory teams should keep clean

The EU pathway is routinely summarised as “approved January 2025”. It was not. The CHMP positive opinion (31 Jan 2025) and the European Commission marketing authorisation (8 Apr 2025) are two separate steps about ten weeks apart[7][10]. The same two-step sequence repeated for TNBC in 2026: CHMP on 23 June, Commission decision on 31 July[8][9]. If you are building an approval tracker, log both dates, not one. Our FDA novel drug approvals tracker follows the same convention.

Safety profile, per the US label

Correction: there is no boxed warning

Datroway’s US prescribing information carries no boxed warning. Interstitial lung disease, ocular reactions, stomatitis and embryo-fetal toxicity appear in Section 5, Warnings and Precautions[4]. Several secondary summaries — including an earlier version of this page — described them as boxed warnings. For regulatory-affairs use, the distinction is material: a boxed warning changes labelling, promotional and risk-communication obligations.

Safety was characterised in 360 patients who received at least one 6 mg/kg dose in TROPION-Breast01, with a median treatment duration of 6.7 months[4].

Most common adverse reactions at 20% or above, including laboratory abnormalities: stomatitis, nausea, fatigue, decreased leukocytes, decreased calcium, alopecia, decreased lymphocytes, decreased haemoglobin, constipation, decreased neutrophils, dry eye, vomiting, increased ALT, keratitis, increased AST and increased alkaline phosphatase[4]. Serious adverse reactions occurred in 15% of patients; permanent discontinuation for an adverse reaction in 3.1%.

Renal impairment signal

The label records a higher incidence of ILD/pneumonitis in patients with mild and moderate renal impairment (creatinine clearance 30 to under 90 mL/min), while still recommending no dose adjustment for that group. Monitor those patients more closely for respiratory reactions. The effect of severe renal impairment on pharmacokinetics is unknown[4].

Dosing per label, not a recommendation: 6 mg/kg by IV infusion once every three weeks (21-day cycle), to a maximum of 540 mg in patients weighing 90 kg or more, until progression or unacceptable toxicity. Dose reductions step to 4 mg/kg, then 3 mg/kg, then permanent discontinuation, with no re-escalation after a reduction[4].

Why TROPION-Breast01 missed overall survival — and what the final analysis showed

TROPION-Breast01 had dual primary endpoints. PFS was met decisively at the 17 July 2023 primary data cut-off[11]; OS was not. That much is well known. What is less often reported is the published final analysis, at a 24 July 2024 data cut-off and a median follow-up of 22.8 months, which confirmed the OS hazard ratio of 1.01[12].

The trial did not permit crossover between arms — a point frequently misstated. The confounder was subsequent therapy: several ADCs became available during the conduct of the study, and their uptake differed between arms. A prespecified sensitivity analysis using inverse probability censoring weighting to adjust for subsequent ADC use produced an adjusted OS hazard ratio of 0.86 (95% CI 0.70 to 1.06)[12]. That remains a confidence interval crossing 1, so it does not establish a survival benefit — but it quantifies the confounding rather than merely asserting it.

The contrast with TROPION-Breast02 is the useful part. In the first-line TNBC setting, where fewer alternatives existed, the trial produced a statistically significant five-month OS improvement[3][13]. Same molecule, same dose, different line of therapy and a very different survival readout.

Nonclinical data, kept in its two separate categories

  • Reproductive and developmental toxicity: the label states plainly that no animal reproductive or developmental toxicity studies were conducted with datopotamab deruxtecan-dlnk. The embryo-fetal warning rests on mechanism, not on molecule-specific reproductive toxicology[4]. The label separately notes US general-population background risks of 2 to 4% for major birth defects and 15 to 20% for miscarriage — baseline figures, not drug-attributable risk.
  • General toxicology: a 3-month repeat-dose study in rats at 200 mg/kg (approximately 29 times the human AUC exposure at 6 mg/kg) found reduced testicular and epididymal weight, germinal epithelium degeneration, seminiferous tubule atrophy and reduced sperm counts in males, and increased atretic ovarian follicles and vaginal mucosal single-cell necrosis in females. All findings except the testicular and epididymal lesions reversed after a 2-month recovery period[4].
  • Genotoxicity: DXd was clastogenic in an in vivo rat bone-marrow micronucleus assay and an in vitro Chinese hamster lung chromosome aberration assay, and non-mutagenic in a bacterial reverse mutation assay. Carcinogenicity studies have not been conducted[4].

Datroway compared with Enhertu

Both are DXd-class ADCs from the same Daiichi Sankyo and AstraZeneca collaboration, and both are frequently searched together — but they target different antigens and therefore treat different populations.

Factual comparison of target, chemistry and regulatory status. Not a recommendation of one agent over the other.
