Detailed Description
The proposed trial is a single arm, two stage trial looking for an efficacy signal in the neoadjuvant setting in patients with PTEN-null tumors. The active therapy is a combination of androgen deprivation therapy, darolutamide, and ipatasertib. Patients will be treated for 6 months prior to prostatectomy, since previous studies have shown that pCR+MRD rate is higher with 6 months of ADT + abiraterone (24%) than 3 months (4%) (Taplan ME et al. J Clin Oncol. 2014;32(33):3705-15). Since the combination has not been evaluated before, a lead-in cohort in patients with castration resistant prostate cancer will be performed to evaluate safety and drug-drug interaction.
The lead-in cohort will enroll 6 patients to assess the safety of ipatasertib and darolutamide. Ipatasertib has already been evaluated in combination with the AR pathway inhibitors abiraterone and enzalutamide, where 400 mg was found to be safe. Therefore patients will receive the expected final dose of darolutamide 600 mg BID and ipatasertib 400 mg daily. Toxicities will be monitored for 28 days, and blood samples will be drawn for pharmacokinetic (PK) studies. If one or fewer patients experience a DLT the trial will advance to the neoadjuvant setting. If two or more patients experience a DLT at 400 mg, the dose will be reduced for already enrolled patients and another 6 patients will be enrolled to evaluate darolutamide 600 mg BID and ipatasertib 200 mg daily.
PK evaluations will continue for a total of 6 months. Enrollment in the neoadjuvant cohort can proceed before PK studies are complete.
Patients in the Phase I portion will have response evaluated at 12 weeks, including PSA response and radiographic response per modified PCWG3. If there is progression on bone scan alone, patients should have confirmatory bone scan at least 6 weeks later. Patients will continue on therapy until the time of progression.

Description
Eligibility Criteria Approximately 26-38 patients with prostate cancer will be enrolled in this study. This includes 6-18 patients in the Phase I de-escalation cohort with metastatic or nonmetastatic castration resistant prostate cancer, and 20 patients in the Phase II neoadjuvant cohort with high risk localized or locally advanced prostate cancer that has PI3K pathway activation.
- For the Phase I de-escalation cohort, the patient must have castration resistant prostate cancer (metastatic or non-metastatic), as defined by PCWG3.
For the Phase II neoadjuvant cohort, the patient must be a candidate for radical prostatectomy at the time of enrollment and be planning to undergo this procedure. The patient must have a histologically-confirmed diagnosis of localized, untreated prostate cancer with high risk features and must have sufficient archival tissue (at least 2 cores) available for targeted sequencing and immunohistochemistry (IHC). The tumor must have PI3K pathway activation. This can be determined by IHC, in which case at least 50% of the tumor tissue evaluated must be negative for PTEN expression by immunohistochemistry on local review. Alternatively, qualifying alteration in PTEN, PIK3CA, or AKT1 on next generation sequencing (NGS) is also acceptable to be eligible, regardless of PTEN expression. If the patient qualifies based on NGS results, IHC must still be performed.
- Qualifying mutations include changes in AKT1 at residues E17, L52, or Q79; in PIK3CA at residues R88, G106, K111, G118, N345, E542, E545, Q546, M1043, H1047, or G1049; in PTEN a R130Q/C/H substitution or a deletion, frameshift, or introduction of early stop codon. The assay must be a CLIA-certified assay, and a copy of the report must be provided.
