PURPOSE The combination of suramin and hydrocortisone has shown clinical benefit in patients with androgen-independent prostate cancer. Widespread use was limited by the complex dose schedules and the need for pharmacologic monitoring. This study reports three sequential pharmacokinetically derived treatment regimens that simplified the administration of suramin and hydrocortisone with reduced toxicity. PATIENTS AND METHODS Three cohorts of patients with advanced prostate cancer that progressed despite castrate levels of testosterone received oral hydrocortisone plus suramin administered in the following manners: (1) a loading dose of suramin followed by a continuous infusion using an adaptive control program (cohort A); (2) an intermittent schedule using a simplified adaptive control schedule (cohort B); and (3) an empiric dosing regimen (cohort C). Drug concentrations were monitored along with the toxicities associated with each regimen. Efficacy was assessed using measurable-disease criteria, radionuclide scans, and posttherapy changes in prostate-specific antigen (PSA) levels. RESULTS Fifty-six patients were treated and plasma suramin concentrations were similar for each regimen. A partial response was observed in 4% (one of 28; 95% confidence interval, 0% to 18.4%) of patients with measurable disease, while 12% (six of 50; 95% confidence interval, 4.5% to 24.3%) had a greater than 80% decline in the baseline PSA level. The median duration of response was 12 months. No responses on radionuclide scans were seen. Anemia and lymphocytopenia were the most common toxicities, while 7% of patients developed a sensory or motor neurotoxicity. In the sequential regimens, the frequency of renal insufficiency (P = .04) and coagulopathy (P < .0001) decreased, while transaminase elevations (P = .05) were more common using intermittent infusions (cohorts B and C) versus continuous infusion schedules (cohort A). CONCLUSION The administration of suramin was simplified and the drug concentrations were maintained. In this cohort of patients with advanced prostate cancer, the clinical activity of suramin using these dosing schedules was limited. Pharmacodynamic issues, patients selection, and criteria to assess efficacy could have effected the clinical outcome.

PURPOSE: To determine the safety and activity of weekly paclitaxel in combination with estramustine and carboplatin (TEC) in patients with advanced prostate cancer. PATIENTS AND METHODS: In a dose-escalation study, patients with advanced prostate cancer were administered paclitaxel (weekly 1-hour infusions of 60 to 100 mg/m2), oral estramustine (10 mg/kg), and carboplatin (area under the curve, 6 mg/mL-min every 4 weeks). Paclitaxel levels were determined 0, 30, 60, 90, and 120 minutes and 18 hours after infusion, and a concentration-time curve was estimated. Once a safe dose was established, a multi-institutional phase II trial was conducted in patients with progressive androgen-independent disease. RESULTS: Fifty-six patients with progressive androgen-independent disease were treated for a median of four cycles. The dose of paclitaxel was escalated from 60 to 100 mg/m2 without the occurrence of DLT. Posttherapy decreases in serum prostate-specific antigen levels of 50%, 80%, and 90% were seen in 67%, 48%, and 39% (95% confidence interval, 55% to 79%, 35% to 61%, 26% to 52%) of the patients, respectively. Of the 33 patients with measurable disease, two (6%) had a complete response and 13 (39%) had a partial response. The overall median time to progression was 21 weeks, and the median survival time for all patients was 19.9 months. Major grade 3 or 4 adverse effects were thromboembolic disease (in 25% of patients), hyperglycemia (in 38%), and hypophosphatemia (in 42%). Significant leukopenia, thrombocytopenia, and peripheral neuropathy were not observed. CONCLUSION: TEC has significant antitumor activity and is well tolerated in patients with progressive androgen-independent prostate cancer.

80 Background: The poly(ADP-ribose) polymerase (PARP) inhibitor rucaparib was granted accelerated approval by the US Food and Drug Administration for patients with BRCA+ mCRPC based on results from the phase 2 TRITON2 study (NCT02952534). The TP53 tumor suppressor gene is among the most frequently mutated genes in human cancers, including mCRPC, and alterations in TP53, PTEN, and RB1 are associated with poor prognosis in patients with prostate cancer and other tumor types. We present data on co-occurring alterations in patients with BRCA+ mCRPC treated with rucaparib in TRITON2. Methods: Patients had progressed on 1–2 lines of androgen receptor-directed therapy and 1 taxane-based chemotherapy and were treated with rucaparib 600 mg BID. Tissue and/or cell-free DNA extracted from plasma samples were profiled comprehensively for genomic alterations using Foundation Medicine, Inc., next-generation sequencing assays. Objective response rate (ORR) was assessed per modified Response Evaluation Criteria in Solid Tumors and Prostate Cancer Working Group 3 criteria by independent radiologic review of patients with measurable disease. Prostate-specific antigen (PSA) response rate (≥50% decrease from baseline) was assessed in all patients. Results: Tissue and/or plasma samples were available for 114/115 patients with BRCA+ mCRPC (visit cutoff date: Dec. 23, 2019). Among patients with BRCA+ mCRPC who had samples available for comprehensive genomic profiling, 36.8% (42/114) had a co-occurring alteration in TP53. Deleterious alterations in PTEN were observed in 34.2% (39/114) of patients, 44% (17/39) of which were homozygous deletions of PTEN. RB1 loss was observed in 12.3% (14/114) of patients and was seen more frequently in patients with measurable disease (18.0%, 11/61) than in patients with non-measurable disease (5.7%, 3/53). Although patients with and without TP53 mutations had generally similar baseline demographics and disease characteristics, visceral disease was more prevalent in patients with TP53 mutations (54.8%; 23/42) than in those without them (29.2%; 21/72). Similar ORR and PSA response rates were seen in patients with BRCA+ mCRPC with or without TP53 mutation, with a non-significant trend towards lower response rates in patients with co-occurring TP53 alterations. Conclusions: Results from TRITON2 showed antitumor activity for rucaparib in patients with BRCA+ mCRPC associated with or without co-occurring alterations in TP53. Demographics and additional efficacy analyses in genomic subgroups with co-occurring alterations in TP53, PTEN, and RB1 will be reported. Clinical trial information: NCT02952534. [Table: see text]

PURPOSE To assess efficacy of intermittent infusion of suramin in patients with androgen-independent prostate cancer who have had disease progression on hydrocortisone. PATIENTS AND METHODS Chemotherapy-naive patients with progressive androgen-independent prostate cancer were given hydrocortisone 40 mg/d and monitored for treatment effect. At the time of disease progression, suramin was administered on a pharmacokinetically derived, 2-week dosing schedule. RESULTS Thirty patients with a median Karnofsky performance status (KPS) of 90% were treated with hydrocortisone. No responses were seen in 12 patients with measurable disease or 29 patients with abnormal bone scans. Thirty patients had an increasing prostate-specific antigen (PSA) level before treatment and six (20%) had a more than 50% decline in PSA from the baseline value for a median of 16 weeks (range, 12 to 52+). Twenty-eight patients had disease progression after a median of 7 weeks (range, 3 to 23), and two patients have continued to receive hydrocortisone for 44 and 52 weeks. Twenty-eight patients received hydrocortisone and suramin, with median suramin concentrations of 97 to 170 micrograms/mL for 4 weeks. No responses in measurable disease and no improvements in bone scans were seen. Five patients (18%) showed a more than 50% decline in PSA levels from baseline, of whom three had previously responded to hydrocortisone. Only two of 24 patients who did not show a posttherapy decline in PSA levels after hydrocortisone had a reduction in PSA levels with the addition of suramin. Toxicity profiles were acceptable with each agent, although a higher proportion of subjects showed hematologic, cardiac, and neurologic events when suramin was added. CONCLUSION Suramin has limited efficacy in patients with androgen-independent prostate cancer who have had disease progression after hydrocortisone.

14618 Background: Based on the known efficacy of docetaxel (D) in Androgen Independent Prostate Cancer (AIPC), and demonstrated activity of the antiangiogenesis agent thalidomide in combination with docetaxel, a Phase I trial in patients (pts) with AIPC with evidence of progression by unidimensionally measurable disease or rising serum Prostate Specific Antigen (PSA) levels after antiandrogen withdrawal was designed. The study evaluates the combination of escalating doses of D and lenalidomide (Ln), a derivative of thalidomide with immunomodulatory and antiangiogenic properties. Pts were permitted to have no more than two prior chemotherapy regimens. Methods: Pts were given D and Ln on a q3 week dose-escalation schedule. Dose Levels of D (mg/m2): Level (L) 1 = 60 L2-L5 =75, given IVPB over 60 minutes in combination with prednisone 5mg po bid. Decadron 20 mg was given 12, 6 hrs and 15 minutes prior to D on D#1. Dose of Ln (mg/day) on D#1–14 of 21-day cycle: L 1 = 10 mg, L2= 10 mg, L3 = 15 mg, L4–20 mg L5 = 25 mg. Patient Characteristics: L1: N = 5. Median Age 66.2 yrs. Median PSA = 101.9 (range 5.9–164.0). Prior CT: none. Prior palliative RT: none. Patients with unidimensionally measurable disease: 4, all in lymph nodes. Patients with bone metastases: 5. Pre-treatment, 1 patient required narcotic analgesics. Results: Five L1 patients are evaluable for toxicity and response. Median number of cycles administered = 4 (range 2–5). Toxicity: There have been no Grade (G) 3 or 4 toxicities. Anti-tumor activity: Two pts (40%) have had a greater than 50% decline in serum PSA on 2 consecutive measurements at least 2 weeks apart. Of 4 pts with unidimensionally measurable disease, all have stable disease by RECIST criteria. Conclusions: At L1, D + Ln has been well tolerated in AIPC. Further dose escalation to L2 and above is planned. [Table: see text]

Purpose: To determine the safety and efficacy of weekly high-dose oral calcitriol (Rocaltrol, Roche Pharmaceuticals, Basel, Switzerland) and docetaxel (Taxotere, Aventis Pharmaceuticals, Bridgewater, NJ) in patients with metastatic androgen-independent prostate cancer (AIPC).Patients and Methods: Thirty-seven patients were treated with oral calcitriol (0.5 μg/kg) on day 1 followed by docetaxel (36 mg/m2) on day 2, repeated weekly for 6 weeks of an 8-week cycle. Patients maintained a reduced calcium diet and increased oral hydration. Prostate-specific antigen (PSA) response was the primary end point, which was defined as a 50% reduction in PSA level confirmed 4 weeks later.Results: Thirty of 37 patients (81%; 95% confidence interval [CI], 68% to 94%) achieved a PSA response. Twenty-two patients (59%; 95% CI, 43% to 75%) had a confirmed > 75% reduction in PSA. Eight of the 15 patients with measurable disease (53%; 95% CI, 27% to 79%) had a confirmed partial response. Median time to progression was 11.4 months (95% CI, 8.7 to 14 months), and median survival was 19.5 months (95% CI, 15.3 months to incalculable). Overall survival at 1 year was 89% (95% CI, 74% to 95%). Treatment-related toxicity was generally similar to that expected with single-agent docetaxel. Pharmacokinetics of either calcitriol or docetaxel were not affected by the presence of its companion drug in an exploratory substudy.Conclusion: The combination of weekly oral high-dose calcitriol and weekly docetaxel is a well-tolerated regimen for AIPC. PSA and measurable disease response rates as well as time to progression and survival are promising when compared with contemporary phase II studies of single-agent docetaxel in AIPC. Further study of this regimen is warranted.

PURPOSE: To investigate the combination of docetaxel, estramustine (EM), and low-dose hydrocortisone in men with hormone-refractory prostate cancer (HRPC). PATIENTS AND METHODS: Combinations of EM with other antimitotic agents such as docetaxel are synergistic in vitro and show significant clinical activity in patients with HRPC. We studied intravenous administration of docetaxel 70 mg/m2, oral estramustine, and low-dose daily hydrocortisone in men with HRPC who demonstrated progression after initial hormone therapy. RESULTS: Of the 47 men enrolled onto this multicenter cooperative group study, 46 were assessable for response and/or toxicity. In the 24 patients with measurable disease, there were three complete and nine partial responses for a measurable disease response rate of 50% (12 of 24 patients; 95% confidence interval [CI], 27% to 73%). In the 44 patients in whom pretreatment prostate-specific antigen (PSA) was elevated, 30 (68%) had a 50% or greater decrease, and 25 (57%) had a 75% or greater decrease in PSA. The combined measurable disease and biochemical response rate in all 46 assessable patients was 54% (three complete responses, 22 partial responses, 95% CI, 37% to 71%). The predominant toxicity was neutropenia, with 26% of patients having grade 3 and 30% having grade 4 granulocytopenia; there were no episodes of febrile neutropenia. Other common but mild adverse effects included malaise/fatigue, peripheral edema, and hyperglycemia. The incidence of thromboembolic events during therapy was 9%. With a median follow-up of 17 months, the median survival was 20 months. The median time to disease progression was 8 months for all patients, and 10 months for those with measurable disease. CONCLUSION: This therapy is efficacious and moderately well tolerated in HRPC and should be compared in a phase III trial with mitoxantrone and prednisone.

12 Background: CheckMate 9KD (NCT03338790) is a phase 2 trial of nivolumab (NIVO; anti-PD-1) in combination with rucaparib, docetaxel (DOCE), or enzalutamide for patients with metastatic castration-resistant prostate cancer (mCRPC). DOCE is a standard-of-care chemotherapy for mCRPC that may potentiate antitumor immune responses, thus supporting its use in combination with NIVO, which has shown limited antitumor activity in mCRPC as monotherapy. We report final analysis results for Arm B (NIVO + DOCE) of CheckMate 9KD. Methods: Arm B enrolled patients with chemotherapy-naive mCRPC with ongoing androgen deprivation therapy and ≤ 2 prior novel antiandrogen therapies (NATs; i.e., abiraterone, enzalutamide, etc.). Patients received NIVO 360 mg + DOCE 75 mg/m2 Q3W + prednisone 5 mg BID for ≤ 10 cycles, followed by NIVO 480 mg Q4W until disease progression/unacceptable toxicity (up to 2 years). Coprimary endpoints were objective response rate (ORR) and prostate-specific antigen response rate (PSA-RR; defined as a ≥ 50% PSA reduction). Secondary endpoints included radiographic progression-free survival (rPFS), overall survival (OS), and safety. Results: Of 84 treated patients with a median age of 71 years (range: 53-88), 27% had visceral disease and 54% had measurable disease. The median number of docetaxel cycles was 8; the median number of nivolumab doses was 11. Median follow up was 15.2 months. The table displays the efficacy outcomes, which appear to show comparable ORR in patients receiving versus not receiving prior NAT. There was 1 (2.2%) complete objective response and 17 (37.8%) partial responses in 45 patients with measurable disease. Any-grade treatment-related AEs (TRAEs) occurred in 95.2% of patients, most commonly fatigue (39.3%), diarrhea (35.7%), and alopecia (34.5%). Grade 3-4 TRAEs occurred in 47.6% of patients, most commonly neutropenia (16.7%). TRAEs led to discontinuation in 29.8% of patients. The most common immune-related AEs were GI (35.7%) or skin-related (26.2%). There were 3 treatment-related deaths (1 pneumonitis related to NIVO; 2 pneumonias related to DOCE). Conclusions: NIVO + DOCE has encouraging clinical activity in patients with chemotherapy-naïve mCRPC, regardless of prior NAT, with a safety profile consistent with those of the individual agents. These outcomes support the ongoing phase 3 CheckMate 7DX trial of NIVO + DOCE vs placebo + DOCE for mCRPC (NCT04100018). Clinical trial information: NCT03338790. [Table: see text]

PURPOSE To determine the therapeutic effects of bicalutamide 200 mg in patients with prostate cancers of different hormone sensitivities. METHODS Patients with progressive prostate cancer were treated with bicalutamide 200 mg daily. Before treatment, patients' tumors were classified on the basis of prior hormone exposure and by serum testosterone levels into androgen-dependent and androgen-independent groups. Prior exposure to flutamide and response to flutamide withdrawal was also considered. Outcomes were reported independently on the basis of posttherapy changes in prostate-specific antigen (PSA), measurable disease, and radionuclide bone scans. RESULTS Outcomes varied by prior hormone exposure as a higher proportion of patients with progression of androgen-dependent tumors showed posttherapy PSA decreases of more than 50% or more than 80%, measurable disease regression, and improvement on radionuclide bone scans than did patients with androgen-independent progression. Within the category of androgen-independent progression, clinical benefit was observed in patients who had previously progressed on flutamide, independent of the response to flutamide withdrawal. Patients who had progressed on a gonadotropin-releasing hormone (GnRH) analog alone had a low response proportion, whereas those who progressed after two or more hormone therapies did not respond. Overall, the drug was well tolerated. After progression on bicalutamide monotherapy, one third of patients with androgen-dependent progression responded to medical castration with a GnRH analog. CONCLUSION Classifying patient tumors on the basis of prior hormone exposure permits a more precise estimate of the potential benefit of a specific hormone therapy for the individual patient. The precision is further increased by reporting the effects of a drug on each parameter of disease independently. The difference in outcomes for patients with androgen-independent progression suggests that the specific hormone therapy administered and the response to that therapy can influence the biology of the relapsing tumor and the sensitivity to subsequent therapies. The sensitivity to bicalutamide after progression on flutamide deserves further study.

Increased Risk

Prostate cancer is among the most commonly diagnosed cancers among men, ranking second in cancer globally and first in Western countries. There are marked variations in incidence globally, and its incidence must be interpreted in the context of diagnostic intensity and screening. The uptake of prostate-specific antigen screening since the 1990s has led to dramatic increases in incidence in many countries, resulting in an increased proportion of indolent cancers that would never have come to light clinically in the absence of screening. Risk factors differ when studying prostate cancer overall versus advanced disease. Older age, African ancestry, and family history are established risk factors for prostate cancer. Obesity and smoking are not associated with risk overall, but are associated with increased risk of advanced prostate cancer. Several additional lifestyle factors, medications, and dietary factors are now emerging as risk factors for advanced disease.

Objectives: The aims of this study were to assess the knowledge of medical students in Lomé about these means of screening for prostate cancer in a context of limited resources and controversy about prostate cancer screening, and to identify the determinants associated with these results. Methods: This was a prospective descriptive and cross-sectional study conducted in the form of a survey of medical students regularly enrolled at the Faculty of Health Sciences of the University of Lomé for the 2019–2020 academic years. Results: Of the 1635 eligible students, 1017 correctly completed the form, corresponding to a rate of 62.20%. The average age was 22 ± 3.35 years. The sex ratio (M/F) was 2.5. Undergraduate students were the most represented (53.69%). Students who had not received any training on prostate cancer were the most represented (57.13%). Only 12.88% of the students had completed a training course in urology. Concerning the prostate-specific antigen blood test, there was a statistically significant relationship between the students’ knowledge and some of their socio-demographic characteristics, namely age (p value = 0.0037; 95% confidence interval (0.50–1.77)); gender (p value = 0.0034; 95% confidence interval (1.43–2.38)); study cycle (p value ˂ 0.0001; 95% confidence interval (0.56–5.13)) and whether or not they had completed a placement in a urology department (p value ˂ 0.0001; 95% confidence interval (0.49–1.55)). On the contrary, there was no statistically significant relationship between students’ knowledge of the digital rectal examination and their study cycle (p value = 0.082; 95% confidence interval (0.18–3.44)). Conclusion: Medical students in Lomé have a good theoretical knowledge and a fair practical level of the digital rectal examination clinical examination and an average theoretical knowledge and a below average practical level of prostate-specific antigen, increasing however along the curriculum in the context of prostate cancer screening.
