- Sacituzumab Tirumotecan is indicated for adult patients with unresectable locally advanced or metastatic triple negative breast cancer (TNBC) who have received at least two prior systemic therapies (at least one of them for advanced or metastatic setting).

Sacituzumab Tirumotecan
Sacituzumab Tirumotecan (sac-TMT, also known as SKB264 or MK-2870) is a next-generation Trop-2-directed antibody-drug conjugate (ADC). It targets Trop-2, a protein overexpressed in multiple epithelial cancers, including breast cancer, lung cancer, and gynecologic malignancies. Early clinical studies suggest encouraging anti-tumor activity with a manageable safety profile, making sac-TMT an important emerging therapy in precision oncology.
It consists of:
- A humanized monoclonal antibody targeting Trop-2
- A cleavable linker
- A belotecan-derived topoisomerase I inhibitor payload
STRENGTH:
- Lyophilized powder (vial) for reconstitution and intravenous infusion (200mg vial)
- Single-use glass vials — sterile, preservative-free
DOSAGE:
Sacituzumab Tirumotecan is approved by China’s NMPA at a standard clinical strength/dosing regimen of 5 mg/kg administered intravenously every other week.

The recommended dosing schedule are as follows:
It is given on a specific schedule, commonly involving day 1 and day 15 of a 28-day cycle, as approved by regulatory authorities.
The approved dosage and administration details are specific to the NMPA registration, and it is crucial to consult the official prescribing information provided by the manufacturer for the safe management of the treatment .
STORAGE:
- Because it is a biological therapeutic, its efficacy and safety depend strictly on temperature control. It must be refrigerated at 2°C to 8°C (36°F to 46°F)
- Should not be frozen
Two significant side effects carry boxed warnings due to their potential severity:
Severe neutropenia and Severe diarrhea.
Severe diarrhea is also a common concern, affecting about 64% of patients, with severe (Grade 3-4) cases occurring in approximately 11% of patients. This can lead to dehydration and kidney problems. Patients should be closely monitored for diarrhea, and if it occurs, infectious causes should be ruled out, followed by prompt initiation of anti-diarrhea medication like loperamide.
Other serious effects include hypersensitivity and infusion-related reactions, which can be severe. Patients should communicate any side effects they experience with their healthcare team promptly. Managing these side effects often involves withholding or reducing the drug dose, along with supportive care such as fluid and electrolyte replacement or administration of granulocyte colony-stimulating factors (G-CSF) for neutropenia.
