Summary:

      Study LVHR is a Phase 3 study which will examine the efficacy and safety of tadalafil 2.5 and

      BPH.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Have BPH Lower Urinary Tract Symptoms (LUTS) based on the disease diagnostic criteria
             at 1st screening.

          -  Have a history of ED based on the disease diagnostic criteria at 1st screening.

          -  Have LUTS with a Total International Prostate Symptom Score (IPSS) greater than or
             equal to 13 at 2nd screening.

          -  Have bladder outlet obstruction as defined by a Peak Urine Flow Rate (Qmax) of greater
             than or equal to 4 to less than or equal to 15 milliliter (mL)/second (sec) (from a
             prevoid total bladder volume as assessed by ultrasound of greater than or equal to 150
             to less than or equal to 550 mL and a minimum voided volume of 125 mL) at 2nd
             screening.

          -  Make at least 4 sexual intercourse attempts during the 4-weeks after 2nd screening as
             recorded in the Sexual Encounter Profile (SEP) diary.

          -  Are sexually active with an adult female partner, and expect to remain sexually active
             with the same adult female partner for the duration of the study.

          -  Agree not to use any other approved or experimental BPH, overactive bladder (OAB), or
             ED treatments as indicated in the protocol at any time during the study.

          -  Have not taken treatments indicated in the protocol prior to the 2nd screening.

        Exclusion Criteria:

          -  Current treatment with nitrates.

          -  Prostate-specific antigen (PSA) greater than 10.0 nanogram (ng)/mL at 1st screening.

          -  PSA greater than or equal to 4.0 to less than or equal to 10.0 ng/mL at 1st screening
             if prostate malignancy has not been ruled out to the satisfaction of a urologist.

          -  Clinical evidence of prostate cancer.

          -  Bladder postvoid residual volume (PVR) greater than or equal to 300 mL by ultrasound
             determination at 1st screening.

          -  History or clinical evidence of certain pelvic, bladder, urinary tract, or urinary
             retention conditions described in the protocol.

          -  Lower urinary tract instrumentation (including prostate biopsy) within 30 days of 1st
             screening.

          -  Clinical evidence of severe hepatic impairment at 1st screening.

          -  Current neurologic disease or condition associated with neurogenic bladder (for
             example, Parkinson's disease or multiple sclerosis).

          -  History of significant renal insufficiency as defined by the protocol.

          -  History of ED caused by other primary sexual disorders including premature ejaculation
             or ED caused by untreated endocrine disease.

          -  Presence of penile deformity judged by the investigator to be clinically significant.

          -  History of certain cardiac or cardiovascular conditions described in the protocol.

          -  History of resuscitated cardiac arrest.

          -  Current treatment with certain medications described in the protocol.

          -  Scheduled or planned surgery (or any procedure requiring general, spinal, or epidural
             anesthesia) during the course of the study.

          -  History of significant central nervous system injuries (including stroke or spinal
             cord injury) within 6 months of 1st screening.

          -  Glycosylated hemoglobin (HbA1c) greater than 9% at 1st screening.

          -  Prior treatment with phosphodiesterase type 5 (PDE5) inhibitors judged by the
             investigator to be ineffective. However, if the investigator judges that a subject's
             lack of response to as-needed PDE5 inhibitors is the result of inadequate coordination
             between dosing and sexual activity with a treatment, the subject may be enrolled.
