Gilead Oncology Trodelvy Overview | GileadPro


Trodelvy®, the first approved TROP-2 directed antibody drug conjugate, has been shown to significantly improve both progression-free survival (p<0.0001) and overall survival (p<0.0001) versus single-agent chemotherapy (SAC) treatment of physician’s choice in second-line and later metastatic triple-negative breast cancer (mTNBC).1

GB: Trodelvy® is indicated for the treatment of adult patients with unresectable locally advanced or mTNBC who have received two or more prior lines of systemic therapies, at least one of them given for unresectable locally advanced or metastatic disease.1

Introducing Trodelvy®
In patients without known brain metastases in the ASCENT trial:*2

median PFS
vs single-agent chemotherapy

Median progression-free survival (PFS): 5.6 months with Trodelvy® (95% CI: 4.3–6.3) vs 1.7 months with single-agent chemotherapy (95% CI: 1.5–2.6); HR: 0.41; 95% CI: 0.32–0.52; p<0.0001†1,2

median OS

Median overall survivial (OS): 12.1 months with Trodelvy® (95% CI: 10.7–14.0) vs 6.7 months with single-agent chemotherapy (95% CI: 5.8–7.7); HR: 0.48; 95% CI: 0.38–0.59; p<0.0001†1-3

generally manageable

5% of patients in both arms discontinued for any adverse reaction.3 The most common adverse drug reactions (reported at a frequency of ≥20%) in the overall TNBC population from pooled data from two clinical studies (IMMU-132-01 and IMMU-132-05 [N=258; ASCENT]) were diarrhoea (64.5%), nausea (64.2%), neutropenia (64.2%), fatigue (52.5%), alopecia (44.3%), anaemia (43.4%), vomiting (38.5%), constipation (36.3%), decreased appetite (28.1%), cough (22.7%), and abdominal pain (20.5%)‡1
In health-related quality of life-evaluable patients in the ASCENT trial:*2

improvements clinically
meaningful vs single-agent chemotherapy

Trodelvy® was noninferior to single-agent chemotherapy on all primary health-related quality of life (HRQoL) domains and superior on global health status/quality of life, physical functioning, fatigue, and pain.§3 Trodelvy® was superior to SAC (SAC; eribulin, vinorelbine, gemcitabine, or capecitabine) for emotional functioning, dyspnoea, and insomnia and non-inferior to SAC for all other secondary domains except diarrhoea.3

*The ASCENT trial was an international, multicentre, open-label, randomised, phase 3 clinical trial that evaluated Trodelvy® as compared with treatment of single-agent chemotherapy of the physician’s choice (eribulin, vinorelbine, gemcitabine, or capecitabine) in 529 patients with second-line or later mTNBC.2

The efficacy results in all patients (N=529) were consistent with the population without known brain metastases (median PFS: 4.8 months vs 1.7 months [HR: 0.43; 95% CI: 0.35–0.54; p<0.001]; median OS: 11.8 months vs 6.9 months [HR: 0.51; 95% CI: 0.41–0.62]).1,2

IMMU-132-01 (NCT01631552) was a phase 1–2, multicentre, single-arm clinical trial that enrolled 108 patients with mTNBC who had received at least two prior treatments for metastatic disease.1

§Primary HRQoL domains: Global health status/quality of life, physical functioning, role functioning, pain, and fatigue. Selected as clinically relevant in the target population and used as primary HRQoL in other published studies.3

Trodelvy® is the first approved TROP-2-directed antibody-drug conjugate that selectively delivers a cytotoxic payload, SN-38, to cancer cells, including TNBC cells and the tumour microenvironment through a bystander effect.1,4

Trodelvy® is the first and only approved TROP-2-directed antibody-drug conjugate1,2

Mechanism of action

90% of TNBC tumours express TROP-25

TROP-2-directed antibody humanised monoclonal antibody1
Used to target and bind to TROP-2, a cell surface antigen highly expressed in multiple tumour types, including in TNBC tumours2,5-7

Anticancer Drug/Cytotoxic Agent (SN-38) is a potent topoisomerase I inhibitor with moderate toxicity1,8,9
High drug-to-antibody ratio of ~8:18,10

Hydrolysable Linker (CL2A) is a moderately stable, hydrolysable linker that protects SN-38 from inactivation and facilitates delivery of the active form of the drug to the cancer cells and tumour microenvironment (bystander effect)11,13
Limits the quantity of free SN-38 in the serum8
