Luxdegalutamide

Luxdegalutamide is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Luxdegalutamide rather than just read about it. In short: Luxdegalutamide, also known as ARV-766 and JSB462, is an investigational oral androgen receptor (AR) degrader being developed by Arvinas for the treatment of metastatic castration-resistant prostate cancer (mCRPC). It belongs to a class of drugs called proteolysis targeting chimeras (PROTACs), which are designed to selectively degrade specific proteins by hijacking the ubiquitin-proteasome system.

Key takeaways

Luxdegalutamide belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Luxdegalutamide to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Luxdegalutamide, also known as ARV-766 and JSB462, is an investigational oral androgen receptor (AR) degrader being developed by Arvinas for the treatment of metastatic castration-resistant prostate cancer (mCRPC). It belongs to a class of drugs called proteolysis targeting chimeras (PROTACs), which are designed to selectively degrade specific proteins by hijacking the ubiquitin-proteasome system. Luxdegalutamide is a second-generation PROTAC AR degrader that has demonstrated a broader efficacy profile and better tolerability compared to its predecessor, ARV-110, in clinical settings. It has shown promise in overcoming resistance associated with certain AR mutations, including the L702H mutation, which is prevalent in up to 24% of treated mCRPC patients. As of 2024, luxdegalutamide is being evaluated in phase I/II clinical trials for prostate cancer.

Mechanism of action Luxdegalutamide is a heterobifunctional PROTAC that targets the androgen receptor for degradation. Unlike conventional androgen receptor antagonists that merely block the receptor's activity, PROTACs like luxdegalutamide recruit the cellular protein degradation machinery to completely eliminate the target protein from the cell. The drug works by forming a ternary complex between the androgen receptor, the PROTAC molecule itself, and an E3 ubiquitin ligase, which then tags the receptor protein for degradation by the proteasome. Luxdegalutamide has demonstrated the ability to degrade both wild-type androgen receptor and clinically relevant AR ligand-binding domain (LBD) mutants, including the most prevalent AR L702H, H875Y, and T878A mutations that commonly arise in treatment-resistant prostate cancer.

Development history The drug entered phase I clinical trials on June 22, 2020, with the primary objective of evaluating safety, tolerability, pharmacokinetics, and pharmacodynamics in patients with metastatic castration-resistant prostate cancer. Arvinas later gained rights to develop the compound and has since partnered with Novartis for global development and commercialization.

Current clinical trials As of 2025, luxdegalutamide is being evaluated in multiple phase II clinical trials for prostate cancer. A major ongoing study aims to evaluate the efficacy and safety of luxdegalutamide (JSB462) at 100 mg and 300 mg once-daily doses in combination with abiraterone compared with standard androgen receptor pathway inhibitors (abiraterone or enzalutamide) in participants with metastatic hormone-sensitive prostate cancer (mHSPC). The study is designed to select the recommended dose of the combination for potential phase III development.

Regulatory status Luxdegalutamide currently holds investigational status and has not received regulatory approval for commercial use in any jurisdiction. The drug is being studied under Investigational New Drug applications in clinical trials conducted by Arvinas and its development partners.

Worked examples

Example 1 — a first encounter with Luxdegalutamide

Start with the simplest possible case. Write down what Luxdegalutamide claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Luxdegalutamide before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Luxdegalutamide ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Luxdegalutamide

In research: Luxdegalutamide appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Luxdegalutamide in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Luxdegalutamide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Benzamides, Benzonitriles, Cyclobutanes, so understanding it makes those chapters shorter.
In everyday life: Look for Luxdegalutamide outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
