This report details current unmet need, changing regulatory
requirement, reimbursement challenges & market dynamics of Prostate Cancer
drugs. Report mention pipeline
Antiandrogens, late stage prostate cancer pipeline drugs/new Mechanism of
action & major companies developing Prostate cancer drugs. It also provides insight on clinical
development strategy of combination pipeline/marketed drugs & therapeutic
competitive landscape to find treatment paradigm fit & market potential of new
drugs for treatment of Prostate Cancer.
Increase in prevalence of Prostate cancer and availability
of new treatment options (Zytiga, Xtandi, Cabazitaxel and Xofigo) in last few
years has extended role of newer oral Antiandrogens to treat metastatic CRPC
patient populations where the unmet need was high. This has expanded WW market size of Prostate
cancer drugs to $7b in 2016 from $2.5b in 2011.
Now nmCRPC, HSPC and Xtandi/Zytiga resistance population are the markets
where in new pipeline drugs are under development.
Reported PhII clinical data of Xtandi, ARN-509 and ODM-201
in nmCRPC when indirectly compared demonstrate the bar is high for ARN-509 to
compete against Xtandi in nmCRPC market and while ODM-201 is few years behind
in clinical development. While in mHSPC
reported clinical results of STAMPEDE study opens door for docetaxel
combination approach as standard of care in first line setting.
Around 8 plus drugs are in PhIII development for Prostate
cancer treatment and 26 plus drugs are in PhII development (21 small molecules)
- success of a few (ARN-509, ODM-201, AZD 5363, GX301) in coming years will
expand nmCRPC ($3.5be), mHSPC market
($1be) and Xtandi/Zytiga resistant population ($1be) market by
2023. Longer duration of therapy and
high prevalence makes earlier setting market more attractive and bigger for
newer options than the late stage if they succeed.
For drugs targeting through androgen pathway - Now trials
and clinical development is underway for second and third generation androgen
receptor inhibitors (ARN-509, ODM-201, ODM-204, EPI-506, VT-464, TAS-3681 and
DR103). While androgen synthesis
inhibitors still needs a proof of concept in clinic due to failure of TAK-700
& TOK-001. Expected data from VT-464
(Apr 2017) & ASN-001 will be important to watch to taste the success for
this class. Androgen receptor degrader
is another MoA in development from a decade and success of in clinic compound
GTX-758 (Data expected anytime from now as study completed in March 2016- less
likely to succeed) will decide the proof of concept.
Other than pipeline drugs targeting androgen pathway, NCE
targeting AKT pathway (AZD5363, Ipatasertib) appears to be more promising to
succeed in late stage, while drugs acting through PARP inhibition (Olaparib,
Niraparib) still needs a taste of success. Other interesting pipeline asset is
LHRH agonist LMIS 50 mg, which is designed to overcome the drawbacks of the
commercial depot products containing GnRH agonists by using a proprietary
delivery system.
Also 6 therapeutic vaccines are in clinical development to
treat prostate cancer. Recently launched PD-L1 IO therapy has increased hope of
treating cancer in much safer way.
Current ongoing studies of late stage IO mab are in Ph I/II clinical
development and would be able to answer of PTEN hypothesis for role of PD-1,
PD-L1 inhibitor to treat prostate cancer in coming years.
Resistant development is another challenge with long term
use of Xtandi/Zytiga and needs to be
addressed by pipeline second/third generation Antiandrogens/ combination
approach with IO/PARP/AKT inhibitors to treat mCRPC. Increase in pricing pressure in developed
market again put inference on Combination approach unless the advantage is
significant and improve the Q0L in earlier setting. Due to that, drugs targeting adjuvant setting
has high bar to deliver (Atezolizumab, GX301, Mipsagargin and Olaparib) in the
clinical development to add significant value.
