Abstract Purpose Treatment of hyperprolactinemia and prolactinomas with ergoline dopamine agonists (DAs) can be complicated by intolerance and resistance. Ropinirole (ROP) is a low cost selective D2/D3 receptor non-ergot DA, approved for treatment of Parkinson’s disease and Restless Leg Syndrome, that has been shown to acutely lower prolactin levels (PRL). This study investigated the efficacy and tolerability of long-term ROP therapy in patients with hyperprolactinemia. Methods & Results Ten healthy women (21-45 yrs) with hyperprolactinemia were treated with ROP (0.25-6.0mg/d) for 6 months in an open-label dose escalation study. Clinical and biochemical status was assessed monthly and ROP doses were up-titrated to achieve normal PRL levels, restore menses, and eliminate galactorrhea. Two subjects had macroprolactinomas, 7 had microprolactinomas, and 1 had idiopathic hyperprolactinemia. 8/10 had previously been treated with cabergoline and/or bromocriptine. 5/10 were intolerant and 1/10 was resistant to ergot DAs. Pituitary MRIs were performed at baseline and 6 months.ROP was initiated at 0.25mg QHS in 9/10 subjects. One subject with severe DA intolerance was initiated on 0.125mg QHS. Subjects reaching a total daily dose (TDD) > 2.0mg/d were transitioned to ROP extended release. At study completion, TDDs ranged from 1-6mg/d, with a median TDD of 2mg/d. Baseline PRL levels were 136 ± 49ng/ml (1.9-25ng/ml). Stable PRL normalization was achieved in 50% of subjects. Of the subjects achieving normal PRL, 4 had microadenomas and 1 had idiopathic hyperprolactinemia, and the median effective TDD was 1mg/d (1-4mg/d, range). Among those not achieving PRL normalization, PRL decreased 46 ± 5.4% (Mean ± SEM) from baseline, at a median TDD of 4.0mg/d (2-6mg/d, range). In the subject with documented resistance to ergot DAs, PRL decreased from 529 to 320ng/ml, after 3 months of ROP on the maximum dose studied (6mg/d), but rose to 690ng/ml at 6 months. During ROP treatment, menses normalized in 57%, and galactorrhea resolved in 67% of affected subjects. At study completion, tumor size was unchanged in 7/8 prolactinomas. A 20% decrease in tumor size was observed in one macroadenoma, accompanied by a 30% reduction in PRL levels. There were no changes in BP, HR, weight, renal or kidney function. Mild adverse effects (AEs) were recorded in 80% of subjects. Fatigue (60%), nausea (40%), and headache (20%) were most common. Reported AEs declined after month 1 and ROP was not discontinued due to intolerance. Conclusion These data provide support for the efficacy of ROP in the treatment of hyperprolactinemia in patients with microprolactinomas and idiopathic hyperprolactinemia. While further study is needed, ROP treatment for hyperprolactinemia could be considered in patients with ergot DA intolerance or significant cardiac valve disease.

2580 Background: YH003, a recombinant, humanized agonistic anti-CD40 IgG2 monoclonal antibody (mAb) specifically recognizes and agonizes CD40 on the antigen-presenting cells to enhance immune responses. Preclinical data have shown potent anti-cancer activity when combined with anti-PD-1 antibodies. Methods: This is an ongoing phase 1 dose-escalation study. Patients with advanced solid tumors receive YH003 by IV administration Q3W as monotherapy at 0.03 to 3.0 mg/kg for the first cycle (21 days) then in combination with Toripalimab at 240 mg Q3W for the 4 subsequent cycles in an accelerated “3+3” design. The safety, tolerability and preliminary efficacy data will be analyzed. Results: As of 31 Dec 2020 data cutoff, 9 patients (pts) were enrolled and treated at 0.03 mg/kg (n = 3), 0.1mg/kg (n = 3), and 0.3mg/kg (n = 3). The median age was 63 years (range 33-68). Baseline ECOG scores were 0 (7 pts) and 1 (2 pts) with a median of 2 prior lines therapy (range 1-7). 5 pts had received prior immunotherapy (PD-1/PD-L1 or PD-1+CTLA-4). As of data cutoff, no dose limiting toxicities (DLT) were observed. No Serious Adverse Event (SAE) or AEs leading to treatment discontinuation were reported. Four drug related AEs were reported including one Grade 1 (G1) choroidal thickening (related to YH003) at 0.03 mg/kg, one G1 fatigue (related to YH003) at 0.1 mg/kg, two G1 febrile episodes (one related to YH003 and the other related to combination treatment) at 0.3 mg/kg. Among 5 patients assessable for response, there were 2 SD (one with anti-PDL1 refractory Merkel cell carcinoma at 0.03 mg/kg and one with anti-PD1 refractory NSCLC at 0.1 mg/kg) and 1 PR with anti-PD1/anti-CTLA4 refractory ocular melanoma at 0.1 mg/kg. Conclusions: YH003 was well tolerated up to 0.3 mg/kg dose levels when combined with Toripalimab and has shown encouraging antitumor activity in patients with advanced solid tumors. Clinical trial information: NCT04481009.
