e19528 Background: Pomalidomide (POM) is a third –generation immunomodulatory drug shown to be safe and effective for the treatment of relapsed/refractory multiple myeloma (RRMM) for patients (pts) previously treated with bortezomib and lenalidomide (LEN) and in combination with dexamethasone it has been shown to overcome resistance in RRMM. In this phase 2 trial, we are evaluating the efficacy, safety and tolerability of POM as a replacement therapy for LEN for pts who have progressed receiving a LEN combination regimen. Methods: This is a phase 2, multicenter, open-label and non-randomized study. Pts who have failed a combination regimen containing LEN were treated with POM along with all of the other drugs previously used in the regimen. POM administered orally (dose is determined based on the previous regimen) on days 1-21 of a 28-day cycle, whereas other drugs are administered using the same schedule(s), dose(s) and drug combination as the last LEN-containing regimen that the patient received and failed. The planned enrollment on the study will be 45 pts. Results: To date, a total of 29 pts have been enrolled, 25 pts are evaluable and 12 pts have discontinued treatment. Of the evaluable pts, 9 (36%) and 16 (64%) received 3mg and 4mg of POM, respectively. The median age of all pts was 72 years (range, 52-81), and 17 (68%) were males. Pts have received a median of 3 prior treatments (range, 1-7). The median follow-up time for all pts is 3.1 months (range, 0.2-8.1). Amongst evaluable pts, 5 (23.8%) pts achieved at least a minimal response, 10 (47.6%) pts showed stable disease while 6 (28.6%) pts exhibited disease progression. At the time of data cutoff, only 17 pts have completed more than 1 full cycle of treatment; and, thus, the overall response and clinical benefit rates are fairly low (14.3% and 23.8%, respectively) but expected to improve with further follow up. The median PFS for the cohort was 7.6 months. Common ≥ Gr3 adverse events were neutropenia (8%), hypomania (4%) and leukopenia (4%). Conclusions: We show thatPOM appears to be promising replacement therapy for LEN in RRMM pts who have progressed within receiving a LEN combination regimen.

1020 Background: The AR is expressed in up to 90% of ER+ breast cancer where it acts as a tumor suppressor. Historically, therapy with synthetic androgens had efficacy, but virilizing side effects and toxicity limited their use. Enobosarm is a selective AR activating agent that does not cause masculinization and has positive attributes such as promotion of bone and improvement of physical function. In a phase 2 study, correlation between the degree of AR staining and antitumor activity in AR+/ER+ patients with metastatic breast cancer (MBC) was examined. Methods: A phase 2, open label, parallel design randomized study was conducted in 136 patients to evaluate the efficacy and safety of enobosarm in heavily pretreated women with AR+/ER+ MBC. Patients were randomized to 9 mg (n=72) or 18 mg (n=64) of oral daily enobosarm. AR expression (%AR nuclei staining) in breast cancer samples was determined centrally by immunohistochemistry. The correlation between %AR staining and clinical outcomes was examined with a focus on the 9mg dose, selected for the phase 3 study and the optimal %AR staining established. Results: Tumor objective outcomes correlated with percent AR staining (Table). Further, using a 40% AR staining cutoff in patients with measurable disease, the clinical benefit rate (CBR) for ≥40% AR is 80% and <40% is 18% (p<0.0001). Best objective tumor response (BOR) in patients with ≥40% AR is 48% and <40% is 0% (p<0.0001). At ≥40% AR, median radiographic progression free survival (rPFS) is 5.47 and mean is 7.15 months vs <40% AR where the median rPFS is 2.72 and mean is 2.7 months. Similar %AR staining correlation was observed in the 18mg cohort. Enobosarm treatment was well tolerated with significant positive effects on quality of life measurements. Conclusions: Enobosarm is a novel oral selective AR activating agent in which a higher % AR staining correlates with a greater antitumor activity. By targeting and activating AR, enobosarm may represent a new hormone treatment approach for AR+/ER+ MBC. The phase 3, ARTEST trial will commence in early 2021 and randomize patients with AR+/ER+/HER2- heavily treated MBC that have progressed on a non-steroidal aromatase inhibitor, fulvestrant and CDK 4/6 inhibitor to receive enobosarm or standard endocrine therapy.
