Definitions

  • the present disclosure relates to combinations of anti-cancer drugs, methods of treatment of prostate cancer with said combinations, and pharmaceutical formulations comprising said combinations.
  • Prostate cancer is the most common non-cutaneous malignancy in men and the second leading cause of death in men from cancer in the western world.
  • Prostate cancer results from the uncontrolled growth of abnormal cells in the prostate gland. Once a prostate cancer tumor develops, androgens such as testosterone promote prostate cancer growth. At its early stages, localized prostate cancer is often curable with local therapy including, for example, surgical removal of the prostate gland and radiotherapy. However, when local therapy fails to cure prostate cancer, as it does in up to a third of men, the disease progresses into incurable metastatic disease (i.e., disease in which the cancer has spread from one part of the body to other parts).
  • metastatic disease i.e., disease in which the cancer has spread from one part of the body to other parts.
  • mCRPC metastatic castration-resistant prostate cancer
  • abiraterone acetate (ZYTIGA®) plus prednisone has been approved for treating metastatic castrate resistant prostate cancer.
  • Niraparib is an orally available, highly selective poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitor, with activity against PARP-1 and PARP-2 deoxyribonucleic acid (DNA)-repair polymerases. Jones P, Wilcoxen K, Rowley M, Toniatti C. Niraparib: A Poly(ADP-ribose) Polymerase (PARP) Inhibitor for the Treatment of Tumors with Defective Homologous Recombination. J Med Chem. 2015 Apr 23;58(8):3302-3314.
  • PARPs are enzymes responsible for repair of DNA single-strand breaks (SSBs) through a process called base excision repair. PARP inhibition leads to an accumulation of unrepaired SSBs, which result in stalling and collapse of replication forks and, consequently, to double-stranded breaks (DSBs). Normally, DSBs are repaired through homologous recombination (HR). If not repaired, DSBs result in cell death.
  • HR homologous recombination
  • DSBs result in cell death.
  • tumor cells with DNA-repair defects involving the HR pathway e.g., Breast Cancer genes [BRCA]-1/2
  • BRCA Breast Cancer genes
  • the present disclosure relates to a combination of abiraterone acetate and niraparib, which can be administered to a mammal, in particular a human, suffering from an androgen receptor (AR)-related disease or condition, in particular cancer, more in particular prostate cancer.
  • AR androgen receptor
  • These pharmaceutical formulations are fixed dose combinations of abiraterone acetate and niraparib.
  • An objective of the present invention is to provide therapies against prostate cancer, including, among others, hormone-sensitive prostate cancer, hormone-na ⁇ ve high-risk prostate cancer, castration-resistant prostate cancer, metastatic castration resistant prostate cancer (mCRPC), metastatic castration sensitive prostate cancer (mCSPC), non-metastatic castration resistant prostate cancer (nmCRPC), biochemical recurrent (BCR) prostate cancer, and localized prostate cancer (LPC).

  • An objective of the present invention is to provide pharmaceutical formulations that support patient compliance, therapy adherence, and therapy efficiency.
  • An objective of the present invention is to provide pharmaceutical formulations that reduce the tablet burden of the patients, e.g., from six or four tablets of abiraterone acetate and niraparib tosylate monohydrate per day to three, or preferably two or one tablet(s) per day.
  • An objective of the present invention is to provide fixed-dose combination (FDC) pharmaceutical formulations with comparable or improved stability or shelf life to the drug dosage forms formulated separately.
  • An objective of the present invention is to provide fixed-dose combination pharmaceutical formulations which are bioequivalent to the drug dosage forms when administered in separate dosage forms.
  • An objective of the present invention is to provide fixed-dose combination pharmaceutical formulations with an immediate release profile for both abiraterone acetate and niraparib.
  • An objective of the present invention is to provide fixed-dose combination pharmaceutical formulations with a good content uniformity or homogeneous distribution of abiraterone acetate and niraparib tosylate monohydrate.
  • the abiraterone acetate and niraparib tosylate monohydrate are homogeneously distributed within an intragranular phase.

  • abiraterone acetate and niraparib tosylate monohydrate are prepared in separate granules, the respective granules are homogenously distributed in a granule blend.
  • Abiraterone acetate and niraparib tosylate monohydrate drug substances have different particles sizes (d50 of 4-5 ⁇ m and d 50 around 50 ⁇ m, respectively), different bulk densities, and different contents (33% and 5-10% (w/w), respectively) in the fixed-dose combinations of the present invention.
  • d50 4-5 ⁇ m and d 50 around 50 ⁇ m, respectively
  • different bulk densities and different contents (33% and 5-10% (w/w), respectively) in the fixed-dose combinations of the present invention.
  • Administering an FDC with accurate and consistent amounts of the two drug substances is critical for ensuring safety and efficacy.
  • Content uniformity may be impacted by formulation manufacturing conditions, such as the inlet air temperature, spray rate, inlet air flow during granulation, and loss on drying during granulation.
  • An objective of the present invention is to provide granules comprising abiraterone acetate and niraparib tosylate monohydrate with a good stratified content uniformity.
  • An objective of the present invention is to provide granules comprising abiraterone acetate and niraparib tosylate monohydrate with a desired particle size distribution, that may be expressed in values of d 10 , d 50 , and/or d 90 . If the granules are too small, this could result in issues during compression when preparing tablets. If the granules are too large, this could result in differences in content uniformity and undesired segregation, issues with compression during tableting, and issues with the dissolution and bioavailability of the APIs.
  • An objective of the present invention is to provide an immediate release film-coated fixed-dose combination pharmaceutical formulation for oral administration, whose ingredients do not cause oxidative degradation of abiraterone acetate, an API known to be sensitive to such degradation.
  • the presence of organic or inorganic impurities and/or degradants and/or metabolites if out of trend can have an impact on patient safety or efficacy of the therapy.
  • An objective of the present invention is to provide fixed-dose combination pharmaceutical formulations with comparable dissolution profiles for abiraterone acetate and niraparib tosylate monohydrate relative to each other.
