Note: Psychological, social, familial, or geographical factors that might preclude adequate study participation should be considered.~* Evidence of a personally signed informed consent indicating that the patient is aware of the neoplastic nature of the disease and has been informed of the procedures to be followed, the experimental nature of the therapy, alternatives, potential benefits, possible side effects, potential risks and discomforts, and other pertinent aspects of study participation.~Exclusion Criteria:~* History of another malignancy except for the following: adequately treated local basal cell or squamous cell carcinoma of the skin; adequately treated, papillary, noninvasive bladder cancer; other adequately treated Stage 1 or 2 cancers currently in complete remission, or any other cancer that has been in complete remission for ≥2 years.~* Rapidly progressive, clinically unstable central nervous system malignancy. Note: Central nervous system imaging is only required in patients with known or suspected central nervous system malignancy.~* Significant cardiovascular disease, including myocardial infarction, arterial thromboembolism, or cerebrovascular thromboembolism within 6 months before the start of study therapy; symptomatic dysrhythmias or unstable dysrhythmias requiring medical therapy; unstable angina; symptomatic peripheral vascular disease; New York Heart Association Class 3 or 4 congestive heart failure; Grade ≥3 hypertension (diastolic blood pressure ≥100 mmHg or systolic blood pressure ≥160 mmHg), or history of congenital prolonged QT syndrome.~* Significant screening electrocardiogram (ECG) abnormalities, including unstable cardiac arrhythmia requiring medication, left bundle-branch block, 2nd-degree atrioventricular (AV) block type II, 3rd-degree AV block, Grade ≥2 bradycardia, or QTcF ≥470 msec.~* Symptomatic or impending cord compression unless appropriately treated beforehand and clinically stable.~* Patients with gastrointestinal disorders likely to interfere with absorption of study medication.~* Major surgery within 4 weeks before the start of study therapy.~* Prior treatment with chemotherapy within 3 weeks or at least 4 half-lives, whichever is longer, before the start of study therapy.~* Prior therapy with any known inhibitor of MNK-1 or MNK-2.~* Treatment with 5-alpha reductase inhibitors within 4 weeks of enrollment.~* Prior flutamide treatment within 4 weeks before the start of study therapy and evidence of withdrawal response.~* Bicalutamide or nilutamide within 6 weeks before the start of study therapy and evidence of withdrawal response.~* Enzalutamide or abiraterone or apalutamid within 4 weeks before the start of study therapy.~  a. Steroids given in conjunction with abiraterone must be washed out for at least 2 weeks prior to Cycle 1 Day 1 unless the investigator chooses to maintain at a dose of ≤10 mg/day prednisone or equivalent.~* Use of herbal products that may have hormonal anti-prostate cancer activity and/or are known to decrease PSA levels (eg, saw palmetto).~* Current use of immunosuppressive medication at the time of randomization, EXCEPT for the following:~  1. intranasal, inhaled, topical steroids, or local steroid injection (eg, intra-articular injection);~ 2. Systemic corticosteroids at physiologic doses ≤10 mg/day of prednisone or equivalent;~ 3. Steroids as premedication for hypersensitivity reactions (eg, computed tomography \[CT\] scan premedication).~* Use of a potent inhibitor or inducer of cytochrome P450 (CYP) 3A4 within 7 days before the start of study therapy or expected requirement for use of a CYP3A4 inhibitor or inducer during study therapy (Appendix 13.5).~* Concurrent participation in another therapeutic clinical trial.~* Any illness, medical condition, organ system dysfunction, or social situation, including mental illness or substance abuse, deemed by the investigator to be likely to interfere with a patient's ability to sign informed consent, adversely affect the patient's ability to cooperate and participate in the study, or compromise the interpretation of study results.

Study Arms:
- tomivosertib (eFT508) (Type: EXPERIMENTAL): Tomivosertib (eFT508) is a novel small-molecule, investigational drug being developed by eFFECTOR Therapeutics, Inc. as an anticancer therapy. Tomivosertib (eFT508) down regulates AR and acts by inhibiting mitogen-activated protein kinase-interacting serine/threonine kinase-1 (MNK1) and MNK2.

Based on this trial design, predict the completion outcome and termination type (if applicable).

Answer: outcome: terminate
termination_type: lack of efficacy
