Benefits of technology

[0025]In another aspect, the invention provides a method for treating or minimizing bone pain due to metastatic bone lesions associated with CRPC, comprising administering a therapeutically effective amount of a pharmaceutical composition comprising Compound of Formula I or the malate salt of Compound of Formula I or another pharmaceutically acceptable salt of Compound of Formula I, to a patient in need of such treatment. In a specific embodiment, the Compound of Formula I is Compound 1.
[0029]In another aspect, the invention provides a method for extending the overall survival in patients with CRPC, comprising administering a therapeutically effective amount of a pharmaceutical composition comprising Compound of Formula I or the malate salt of Compound of Formula I or another pharmaceutically acceptable salt of Compound of Formula I, to a patient in need of such treatment.

Problems solved by technology

Despite progress in systemic therapy for CRPC, improvements in survival are modest, and virtually all patients succumb to this disease within about 2 years.
The primary cause of morbidity and mortality in CRPC is metastasis to the bone, which occurs in about 90% of cases.
Although most CRPC patients with bone metastases display features of both types of lesions, prostate cancer bone metastases are often osteoblastic, with abnormal deposition of unstructured bone accompanied by increased skeletal fractures, spinal cord compression, and severe bone pain.

embodiments

[0048]In one embodiment the compound of Formula I is the compound of Formula Ia:

or a pharmaceutically acceptable salt thereof, wherein:

[0049]R1 is halo;

[0050]R2 is halo; and

[0051]Q is CH or N.

[0052]In another embodiment, the compound of Formula I is Compound 1:

or a pharmaceutically acceptable salt thereof. As indicated previously, compound 1 is referred to herein as N-(4-{[6,7-bis(methyloxy)quinolin-4-yl]oxy}phenyl)-N-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide. WO 2005 / 030140 discloses Compound 1 and describes how it is made (Example 12, 37, 38, and 48) and also discloses the therapeutic activity of this compound to inhibit, regulate and / or modulate the signal transduction of kinases, (Assays, Table 4, entry 289). Example 48 is on paragraph [0353] in WO 2005 / 030140.

[0053]In other embodiments, the compound of Formula I, Ia, or Compound 1, or a pharmaceutically acceptable salt thereof, is administered as a pharmaceutical composition, wherein the pharmaceutical composition addition...
