TPS5096 Background: NEPC can rarely arise de novo but more commonly arises as a mechanism of resistance in the setting of advanced prostate cancer. Transformation to NEPC is likely promoted by potent hormonal therapies and is currently under-recognized. There is no effective therapy for NEPC and most patients (pts) survive less than one year. We have found that Aurora kinase A (AURKA) and N-myc (MYCN) are significantly overexpressed and amplified in NEPC compared to prostate adenocarcinoma, and cooperate to induce neuroendocrine (NE) differentiation in prostate cancer (Beltran et al, Cancer Disc 2011). In preclinical models, aurora kinase inhibition results in dramatic and preferential anti-tumor activity in NEPC. Methods: In this single arm, multi-institutional Phase II trial, pts with metastatic prostate cancer need to meet at least one NEPC entry criterion: 1) histologic diagnosis of small cell or NEPC, 2) >50% immunohistochemical staining for NE markers, 3) development of liver metastases in absence of PSA progression, or 4) serum chromogranin >5x normal or neuron specific enolase >2x normal. Study will be open at 10 institutions including PCCTC sites. After a mandatory on-study research biopsy, pts will be treated with MLN8237, an orally administered Aurora kinase A inhibitor at 50 mg twice daily for 7 days repeated every 21 days. The primary endpoint is objective response rate (ORR). Secondary endpoints include overall survival, progression free survival, PSA response rate, circulating tumor cell response, and serum NE marker response to therapy. A number of correlative studies including AURKA, MYCN, AR, and exome and RNAseq are embedded in this trial in order to molecularly define this aggressive and poorly characterized disease. A Simon 2-stage design will be employed with up to 60 subjects providing 80% power to determine if the true ORR is >30% and 95% power if the true ORR is <15%, assuming a 5% level of significance. A subset of at least 20% meeting histologic entry criteria is embedded.

Dipeptidyl Peptidases

140 Background: BXCL701 (talabostat previously PT100) is an oral small molecule inhibitor of dipeptidyl peptidases (DPP) specifically DPP4, DPP8 and DPP9, which trigger macrophage cell death via pyroptosis resulting in proinflammatory stimulation of the innate immunity pathway. BXCL701 also inhibits fibroblast activation protein (FAP) releasing the FAP-mediated block of T-cell migration into the tumor. Expression of PD-L1 correlates with amplification of DPP8 and DPP9. In syngeneic animal models, significant tumor responses were observed when BXCL701 was used with checkpoint inhibition. Methods: A phase 1b, multicenter study was undertaken. Eligible patients (pts) had progressing mCRPC (PCWG3), at least 1 line of systemic therapy and ≤ 2 lines of cytotoxic chemotherapy for mCRPC, no prior anti-PD-1/PD-L1 or other T-cell directed anti-cancer therapy, and an ECOG PS of ≤ 2. Pts received fixed dose pembro (200mg IV q21 days) with escalating doses of BXCL701 (0.4mg and 0.6mg PO QD days 1-14 of 21-day cycles) using a 3 X 3 design. The key endpoints were safety and identification of the recommended phase 2 dose (RP2D) for the combination. Composite response (RECIST, PSA, CTC) was also assessed. Results: 3 pts were treated at the initial dose level for at least 4 cycles. All pts remain on treatment. No DLT or SAEs were reported. Grade 3 treatment related adverse events (TRAE) were limited to thrombocytopenia with transfusion in 1 pt. The only TRAE reported in more than one pt was hypocalcemia (2 pts). Safety assessment of BXCL701+pembro is ongoing at the final dose escalation cohort. As DPP9 is amplified in approximately 17% of treatment associated small cell/neuroendocrine prostate cancer (tSCNC) compared to 5% or less in the broader prostate cancer population, the Phase 2 portion of this study will be limited to patients with evidence of t-SCNC or de novo SCNC, an aggressive phenotype with poor outcomes. Conclusions: BXCL701 0.4mg QD on days 1 to 14 of 21-day cycle plus pembrolizumab 200 mg IV on day 1 every 21 days is safe in pts with mCRPC. The final dose escalation supporting RP2D will be presented. Clinical trial information: NCT03910660.
