What You Need to Know Before You Apply

What is the purpose of this trial?

The primary objective of this study is to assess overall survival (OS) with sacituzumab govitecan-hziy in comparison with treatment of physician's choice (TPC) in participants with metastatic or locally advanced unresectable urothelial cancer (UC).

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have had certain cancer treatments recently, like chemotherapy or radiation, within 2-4 weeks before starting the trial. It's best to discuss your specific medications with the trial team.

What safety data exists for Sacituzumab Govitecan-hziy?

Sacituzumab Govitecan-hziy, also known as Trodelvy, has been associated with side effects like neutropenia (low white blood cell count), diarrhea, colitis (inflammation of the colon), and sepsis (a severe infection). These side effects often occur within 30 days of starting treatment, and some may lead to hospitalization, especially in males. ^{1 2 3 4 5}

What makes the drug sacituzumab govitecan-hziy unique for treating urothelial cancer?

Sacituzumab govitecan-hziy is unique because it is an antibody-drug conjugate that specifically targets Trop-2, a protein often found in high amounts on cancer cells, and delivers SN-38, a powerful cancer-fighting agent, directly to the tumor. This targeted approach allows for higher concentrations of the drug to reach the cancer cells, potentially improving effectiveness compared to standard treatments. ^{1 3 4 5 6}

What data supports the effectiveness of the drug Sacituzumab Govitecan-hziy for treating urothelial cancer?

Sacituzumab govitecan has shown promising results in patients with metastatic urothelial carcinoma, especially those who have not responded to other treatments, with preliminary studies indicating it can help shrink tumors. It has also been approved for treating a type of breast cancer, which suggests its potential effectiveness in other cancers. ^{1 3 4 5 7}

Published Research Related to This Trial

Sacituzumab govitecan (SG) is an effective treatment for locally advanced and metastatic urothelial cancer, showing a 27% objective response rate in the TROPHY-U-01 phase II trial.

While SG has common side effects like diarrhea and neutropenia, these can be managed with supportive care, and it has received accelerated approval for patients who have previously undergone platinum-based chemotherapy and PD-1 or PD-L1 inhibitor treatments.

Current and emerging role of sacituzumab govitecan in the management of urothelial carcinoma. Mathew Thomas, V., Tripathi, N., Agarwal, N., et al.[2022]

In a phase II study involving 113 patients with metastatic urothelial carcinoma who had previously progressed on platinum-based chemotherapy and checkpoint inhibitors, sacituzumab govitecan (SG) demonstrated an objective response rate of 27%, indicating significant efficacy in this difficult-to-treat population.

SG was associated with a manageable safety profile, with the most common severe side effects being neutropenia (35%) and diarrhea (10%), leading to a 6% discontinuation rate due to treatment-related adverse events.

In a phase I trial involving 23 patients with metastatic urothelial carcinoma, the combination of sacituzumab govitecan (SG) and enfortumab vedotin (EV) demonstrated a high objective response rate of 70%, with three patients achieving complete responses.

The study identified a safe dose for further testing, with 78% of patients experiencing grade ≥3 adverse events, indicating that while the treatment is effective, careful monitoring for side effects is necessary.

The Double Antibody Drug Conjugate (DAD) phase I trial: sacituzumab govitecan plus enfortumab vedotin for metastatic urothelial carcinoma. McGregor, BA., Sonpavde, GP., Kwak, L., et al.[2023]

Sacituzumab govitecan is an antibody-drug conjugate that targets Trop-2 and delivers a topoisomerase I inhibitor, showing promise in treating metastatic triple-negative breast cancer (mTNBC) after at least two prior therapies.

In April 2020, it received accelerated approval in the USA for mTNBC, and it is currently undergoing further clinical trials for various cancers, indicating its potential as a versatile treatment option.

Sacituzumab Govitecan: First Approval. Syed, YY.[2021]

Sacituzumab govitecan (IMMU-132) demonstrated a predictable pharmacokinetic profile and manageable toxicity in patients with advanced epithelial cancers, with doses of 8 mg/kg (n=81) and 10 mg/kg (n=97) showing safety and efficacy.

The treatment resulted in objective responses in various cancer types, particularly metastatic triple-negative breast cancer, supporting the use of the 10 mg/kg dose for future clinical development.

A total of 1,884 adverse event reports related to sacituzumab govitecan were analyzed, identifying 114 adverse event signals, with most occurring within 30 days of treatment initiation, highlighting the importance of monitoring for early reactions.

Risk factors for hospitalization due to adverse events included being male and experiencing conditions like colitis, febrile neutropenia, and sepsis, indicating specific patient profiles that may require closer observation during treatment.

In a phase 1/2 trial involving 108 patients with heavily pretreated metastatic triple-negative breast cancer, sacituzumab govitecan-hziy demonstrated a response rate of 33.3%, with a median duration of response of 7.7 months, indicating its efficacy in this challenging patient population.

The treatment was associated with significant myelotoxic effects, including anemia and neutropenia, but overall survival was promising at a median of 13.0 months, highlighting the need for careful monitoring of side effects.
