What Is Sacituzumab Tirumotecan Used For?

Sacituzumab tirumotecan, often shortened to sac-TMT, is a targeted cancer medicine developed in China by Sichuan Kelun-Biotech Biopharmaceutical. It is sold there under the brand name 佳泰莱® and was first approved for triple-negative breast cancer, one of the hardest breast cancers to treat once it has spread.

China's National Medical Products Administration (NMPA) has approved it for four groups of adults:

  • Triple-negative breast cancer (November 2024): unresectable locally advanced or metastatic disease after at least two earlier systemic treatments, with at least one of them given for advanced or metastatic disease
  • EGFR-mutant non-small cell lung cancer (March 2025): locally advanced or metastatic non-squamous disease that has progressed after an EGFR tyrosine kinase inhibitor and platinum-based chemotherapy
  • EGFR-mutant non-small cell lung cancer (September 2025): locally advanced or metastatic non-squamous disease that has progressed after an EGFR tyrosine kinase inhibitor
  • HR-positive, HER2-negative breast cancer (February 2026): unresectable or metastatic disease (HER2 IHC 0, 1+ or 2+/ISH-negative) after hormone therapy and at least one line of chemotherapy for advanced disease

It is a prescription cancer medicine and should only be used under a medical oncologist.

How It Works

This medicine is an antibody-drug conjugate, or ADC. The antibody part finds TROP2, a protein found in large amounts on the surface of many breast and lung cancer cells. Once the cancer cell pulls the medicine inside, it releases its payload, a chemotherapy-type drug called KL610023 that damages the cell's DNA so it cannot divide. Each antibody carries about 7.4 payload molecules, and because the payload can pass through cell membranes it can also reach nearby cancer cells. The idea is to deliver strong treatment to the tumour while sparing more of the healthy body.

What the Trials Showed

In the phase 3 OptiTROP-Breast01 trial, published in Nature Medicine in 2025, 263 people with metastatic triple-negative breast cancer who had already had at least two treatments were given either this medicine or standard chemotherapy. The time before the cancer grew again was 6.7 months against 2.5 months, and the risk of death was cut by nearly half (hazard ratio 0.53). Median survival had not yet been reached in the sac-TMT group, against 9.4 months with chemotherapy. 45.4% of patients responded to treatment, compared with 12.0% on chemotherapy.

For HR-positive, HER2-negative breast cancer, the phase 3 OptiTROP-Breast02 trial found that the time before the cancer grew again was 8.3 months against 4.1 months with chemotherapy chosen by the doctor, and 41.5% responded compared with 24.1%.

Recommended Dosage

The dose in the Chinese prescribing information is:

  • 5 mg per kg of body weight, given as a drip (infusion) into a vein, never as a quick injection
  • Once every two weeks
  • Continued until the cancer grows or side effects become too much

The first four infusions run for about 90 minutes, and the patient is watched for at least 90 minutes afterwards; later infusions can be shorter if there has been no reaction. Medicines to prevent infusion reactions are given before every dose (an antihistamine and a fever and pain reliever, plus a steroid and a stomach-acid blocker for the first four doses). The medicine comes as a freeze-dried powder in 200 mg and 100 mg vials, which the hospital pharmacy dissolves and dilutes. Because the dose depends on body weight, the number of vials changes from patient to patient. Your oncologist sets the exact plan and may lower the dose if side effects appear.

This information is not a treatment plan. For personalized medical advice, consult your doctor and refer to the full prescribing information.

Warnings and Precautions

Blood counts: the main side effects are on the blood. In the OptiTROP-Breast01 trial, anaemia affected 82.3% of patients (severe in 29.2%), low neutrophils 78.5% (severe in 34.6%) and low platelets 40.8% (severe in 13.1%). Fever with low neutrophils was uncommon (1.5%). Most severe drops happened in the first two cycles and usually recovered within about two weeks. Blood counts are checked every week for the first two months and then before each cycle.

  • Mouth sores: stomatitis affected 49.2% of patients and was severe in 10.0%. Tell your care team early about pain or ulcers in the mouth, as treatment and dose changes help.
  • Diarrhoea: reported in 13.1%, rarely severe.
  • Lungs: lung inflammation (pneumonitis) was rare, seen in 1 of 130 patients. Report a new cough or breathlessness straight away.
  • Eyes: dry eye (2.3%) and blurred vision (1.5%) were occasionally reported.

Overall: about 3 in 10 patients (30.8%) needed a lower dose, but only 1.5% stopped treatment because of side effects. One patient died from a treatment-related cause (multiple organ failure). Safety in pregnancy, breastfeeding and children has not been established.

Documentation & Availability

What documents are required to import Sacituzumab Tirumotecan to India?

The injection can be imported only in the patient's name, by the patient or a government hospital, in line with India's import regulations for unapproved medicines. You will need:

  • A valid prescription from a qualified medical oncologist
  • Pathology and biomarker reports confirming the cancer type (for example triple-negative or HR-positive/HER2-negative breast cancer, or EGFR-mutant lung cancer), with details of earlier treatments
  • Patient ID proof (issued by the Government of India)

How is the order confirmed?

Once we have received and checked a valid prescription and, where needed, an import permit.

Is Sacituzumab Tirumotecan available in India?

No. It is approved only in China (approval number 国药准字S20240052). It has no CDSCO approval, it is not sold in Indian pharmacies, and the US FDA and European Medicines Agency have not approved it either.

Patients can still get it legally through the Named Patient Program (NPP), which allows a medicine not registered in India to be imported for one specific patient on a prescription. It should not be confused with Trodelvy (sacituzumab govitecan), which is a different TROP2-targeted medicine from another company. For another TROP2 antibody-drug conjugate available through import, see our page on Datroway.

It can be made available to patients, doctors, and hospitals across major cities in India, including Gurgaon, Delhi, Bangalore, Mumbai, Navi Mumbai, Thane, Hyderabad, Mysore, Kerala, Chennai, Coimbatore, Madurai, Kolkata, Ahmedabad, Surat, Vadodara, Pune, Nagpur, Nashik, Jaipur, Udaipur, Lucknow, Kanpur, Gorakhpur, Chandigarh, Mohali, Faridabad, Noida, Ghaziabad, Kochi, Trivandrum, Kozhikode, Thrissur, Kannur, Mangalore, Bhubaneswar, Patna, Ranchi, Raipur, Guwahati, Visakhapatnam, Vijayawada, Goa, Jammu, Srinagar, Dehradun, Bhopal, Indore, Ludhiana, Amritsar, and others — and can facilitate delivery to the patient's treating hospital. Orders are confirmed only after receipt of a valid doctor's prescription and an import permit, where applicable.

Sourcing & Delivery

NamedPatientProgram.com (NPP) sources this medicine through the manufacturer's authorised supply channels in China and arranges supply to patients, doctors, and hospitals under applicable legal provisions. The Chinese label describes taking the vial out of the refrigerator before it is prepared, so the vials are kept cold and shipped with cold-chain, temperature-controlled shipping, following the exact temperature printed on the pack, and delivered to the treating hospital. Because treatment is given every two weeks and the dose depends on weight, we plan quantities ahead for each cycle. All prescriptions are dispensed and checked by registered pharmacists and dispatched from New Delhi, India, after legal requirements are fulfilled.
