2. Male participants who are ≥18 years of age
3. In the opinion of the investigator, the participants have a life expectancy of at least 3 months.
4. Two consecutively rising PSA values or two out of three rising PSA values (2.0 ng/mL is the minimum ending value for PSA) at a minimum of 1-week intervals
5. Have a Karnofsky Performance Score (KPS) equal to or greater than 70

6. Have the following laboratory parameters (may be assessed locally):

   1. Platelet count ≥50 x 10E3/µL

   4. Liver enzymes [aspartate transaminase (AST), alanine transaminase (ALT)] ≤2 x ULN
7. Able to provide written informed consent prior to any study specific screening procedures with the understanding that the patient has the right to withdraw from the study at any time, for any reason without prejudice

Exclusion Criteria:

1. The patient has a history of another primary cancer, with the exception of:

   2. Other primary solid tumor with no known active disease presents that in the opinion of the investigator that will not affect patient outcome in the setting of current prostate cancer diagnosis.
2. Contraindication to propranolol, etodolac
3. Patients on beta blockers
4. Patients receiving chemotherapy (e.g., docetaxel, cabazitaxel, taxane, or platinum as single agents or in combination) as their cancer treatment

7. Resting heart rate less than 60 bpm at time of screening
8. Any uncontrolled, intercurrent illness that in the opinion of the Investigator may interfere with study evaluation. Participants with uncontrolled diabetes will be excluded from the study.
9. On chronotropic drugs (acetylcholine, digoxin, diltiazem, verapamil, atropine, dopamine, dobutamine, epinephrine, isoproterenol)
10. Active clinically serious infections [> Grade 2 National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version 4.0]

12. Known or suspected allergy to the investigational agents or any agent given in association with this trial (hypersensitivity reaction, hives, rash, difficulty breathing swelling of your face, lips, tongue, or throat)
13. Any condition that is unstable or which in the opinion of the Investigator could jeopardize the safety of the patient and his/her compliance in the study
14. Patients with uncontrolled diabetes or insulin resistance
15. Participation in any other investigational trial in which receipt of investigational drug or device occurred within 30 days prior to screening for this study
