Abstract

This invention is directed to selective androgen receptor degrader (SARD) compounds including heterocyclic rings and pharmaceutical compositions and uses thereof in treating prostate cancer, advanced prostate cancer, castration resistant prostate cancer, triple negative breast cancer, other cancers expressing the androgen receptor, androgenic alopecia or other hyperandrogenic dermal diseases, Kennedys disease, amyotrophic lateral sclerosis (ALS), abdominal aortic aneurysm (AAA), and uterine fibroids, and to methods for reducing the levels of androgen receptor-full length (AR-FL) including pathogenic or resistance mutations, AR-splice variants (AR-SV), and pathogenic polyglutamine (polyQ) polymorphisms of AR in a subject.

Claims (27)

2. The compound according to claim 1 , wherein the compound exhibits at least one of binding to the androgen receptor (AR) through an alternate binding domain in the N-terminal domain (NTD), AR antagonism in vivo of an AR target organ, AR-splice variant (AR-SV) degradation activity, AR-full length (AR-FL) degradation activity, AR-SV inhibitory, AR-FL inhibitory activity, or AR antagonism in vivo of an AR target organ.

3. A pharmaceutical composition comprising a SARD compound according to claim 1 , optical isomer, or any mixture of optical isomers, pharmaceutically acceptable salt, pharmaceutical product, hydrate or any combination thereof, and a pharmaceutically acceptable carrier.

4. The pharmaceutical composition according to claim 3 , wherein the pharmaceutical composition is formulated for topical use or for oral use.

5. A method of treating prostate cancer (PCa) or increasing the survival of a male subject suffering from prostate cancer comprising administering to the male subject a therapeutically effective amount of a SARD compound according to claim 1 , optical isomer, or any mixture of optical isomers, pharmaceutically acceptable salt, pharmaceutical product, hydrate or any combination thereof.

6. The method according to claim 5 , wherein the prostate cancer is at least one of advanced prostate cancer, refractory prostate cancer, castration resistant prostate cancer (CRPC), metastatic CRPC (mCRPC), non-metastatic CRPC (nmCRPC), or high-risk nmCRPC.

7. The method according to claim 5 further comprising administering androgen deprivation therapy (ADT).

8. The method according to claim 5 , wherein the prostate cancer is resistant to treatment with an androgen receptor antagonist.

9. The method according to claim 8 , wherein the androgen receptor antagonist is at least one of enzalutamide, apalutamide, bicalutamide, abiraterone, ODM-201 [darolutamide], EPI-001, EPI-506, AZD-3514, galeterone, ASC-J9, flutamide, hydroxyflutamide, nilutamide, cyproterone acetate, ketoconazole, or spironolactone.

11. A method of treating triple negative breast cancer in a subject comprising administering to the subject a therapeutically effective amount of a SARD compound according to claim 1 , optical isomer, or any mixture of optical isomers, pharmaceutically acceptable salt, pharmaceutical product, hydrate or any combination thereof.
