Abstract

The disclosure provides compounds of Formula (I) or a pharmaceutically acceptable salt thereof, wherein W 1 , W 2 , Y, Z, M, L, C y , C z , R 1 , R 2 , R 3 , R 4 , R 2a , R y , R z , and the subscripts m, n, q, and r are as described herein. The compounds or their pharmaceutically acceptable salts can inhibit the G12C mutant of Kirsten rat sarcoma (KRAS) protein and are expected to have utility as therapeutic agents, for example, for treating cancer. The disclosure also provides pharmaceutical compositions which comprise compounds of Formula (I) or pharmaceutically acceptable salts thereof. The disclosure also relates to methods for use of the compounds or their pharmaceutically acceptable salts in the therapy and prophylaxis of cancer and for preparing pharmaceuticals for this purpose.

Claims (18)

1. A method of treating cancer comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof to a subject in need of such treatment, wherein the compound is selected from the group consisting of:

2. The method of claim 1 , further comprising administering an additional active agent to the subject, wherein the additional active agent is an anti-cancer agent.

3. The method of claim 2 , wherein the anti-cancer agent is selected from an EGFR inhibitor, an anti-PD-1 agent, a SHP2 inhibitor, and an ERK inhibitor.

4. The method of claim 3 , wherein the anti-cancer agent is an EGFR inhibitor.

5. The method of claim 3 , wherein the anti-cancer agent is an anti-PD-1 agent.

6. The method of claim 5 , wherein the anti-PD-1 agent is pembrolizumab.

7. The method of claim 3 , wherein the anti-cancer agent is a SHP2 inhibitor.

8. The method of claim 3 , wherein the anti-cancer agent is an ERK inhibitor.

9. The method of claim 1 , wherein the cancer is selected from pancreatic cancer, colorectal cancer, and lung cancer.

10. The method of claim 3 , wherein the cancer is selected from pancreatic cancer, colorectal cancer, and lung cancer.

11. The method of claim 1 , wherein the cancer is mediated by a KRAS G12C mutation.

12. The method of claim 1 , wherein the subject is a human.

13. The method of claim 12 , wherein the compound or the pharmaceutically acceptable salt thereof is administered orally.

14. A method of treating cancer comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof to a subject in need of such treatment, wherein the compound is:

15. A method of treating cancer comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof to a subject in need of such treatment, wherein the compound is:

16. A method of treating cancer comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof to a subject in need of such treatment, wherein the compound is:

17. A method of treating cancer comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof to a subject in need of such treatment, wherein the compound is:
