e16184 Background: Hepatic derangement commonly accompanies advanced HCC (aHCC) and limits the use of systemic therapies. We aimed to evaluate the use of single agent anti-PD-1 nivolumab or pembrolizumab in Child-Pugh (CP) grade B or C patients with aHCC. Methods: Consecutive aHCC patients with CP grade B (CPB) or C (CPC) liver function who received single agent nivolumab or pembrolizumab were analysed. Objective response rate (ORR), time-to-progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were assessed. Results: Between May 2015 and June 2020, 61 patients were included. The median age was 60 (range 28-82). 81% and 4.8% had hepatitis-B and hepatitis-C related HCCs respectively. 72.1% (n = 44) were of CPB and 27.9% (n = 17) were of CPC. Amongst CPB patients, 19 (31.1% of all patients) had CP score 7 (CP7) and 25 (41.0% of all patients) had CP score 8 or 9. The median follow-up was 2.3 months. The ORR of CPB and CPC patients were 6.8% and 0% respectively (p = 0.553). The TTP of CPB and CPC patients were 2.1 months (95% C.I. 1.4-2.8) and 1.4 months (95% C.I. 0.6-2.1) respectively (p = 0.204). CPB patients had significantly better OS than CPC patients (3.1 months (95% C.I. 1.4-4.7), vs. 1.7 months (95% C.I. 1.0-2.4), p = 0.041). Compared to CP score ≥8 (CP≥8) patients, CP7 patients had significantly better OS (median OS CP7 6.7 months (95% C.I. 4.0-9.3), vs. CP≥8 1.8 months (1.2-2.4), p = 0.002). Patients with diuretic-refractory ascites had significantly worse OS compared to those without (1.7 months (95% C.I. 1.0-2.5) vs. 3.7 months (95% C.I. 0.1-7.3), p = 0.004). Portal vein (PV) thrombosis was also significantly associated with inferior survival, with median OS of patients with any PV thrombosis being 1.8 months (95% C.I. 1.0-2.5), compared to 5.3 months (95% C.I. 2.4-8.1) of those without (p = 0.004). The median number of doses given was 3 (range 1-34). Median treatment duration was 5.0 weeks (range 0-77). Overall, 25.4% of patients experienced TRAEs and 4.8% experienced grade ≥3 TRAEs. The most common TRAEs were skin-related (13.1%) and constitutional symptoms (6.6%). Conclusions: Nivolumab/pembrolizumab had acceptable safety in CPB/C patients with aHCC. CP7, absence of diuretic-refractory ascites and lack of PV thrombosis were associated with better survival.

7556 Background: Cirmtuzumab (Cirm) is a humanized monoclonal antibody that inhibits the tumor promoting activity of ROR1 and had demonstrated additive/synergistic activity with many anti-cancer agents including ibrutinib (Ibr). Methods: Patients (Pts) with relapsed or refractory (RR) MCL or treatment naïve (TN) or RR CLL were enrolled. In Part 1 (Dose Escalation), doses of Cirm IV q2wks x5 then q4wks of 2-16 mg/kg and 300 or 600 mg were examined. Safety of Cirm alone was assessed during the first 28 days, then Ibr was started at approved doses for each indication. Cirm 600 mg IV q2wks x3 then q4wks in combination with Ibr starting day 0 was chosen as the recommended dosing regimen for use in Part 2 (Expansion) and Part 3 (CLL only, Cirm/Ibr vs. Ibr alone). Results: Twelve evaluable MCL pts were enrolled into Part 1, and 5 into Part 2. Median number of prior regimens was 2 (1-5), including pts relapsing after Ibr (4), auto-SCT (3), auto-SCT/ allo-SCT (1), auto-SCT/CAR-T (1). In CLL, 34 evaluable pts (12 TN and 22 RR) enrolled into Part 1 (18) or Part 2 (16). At least 74% of CLL pts in Parts 1 and 2 were high risk as determined by unmutated IGHV, del17p, and/or del11q. In Part 3, 22 evaluable pts received Cirm/Ibr (15) or Ibr (7). As of the 30OCT2020 safety cut-off for MCL and CLL, common TEAEs (all grades) included diarrhea (41%), contusion (39%), fatigue (39%), URI (31%), hypertension (25%) arthralgia (23%). Grade ≥3 neutropenia was 13% and thrombocytopenia 1%. There were no Cirm dose reductions or discontinuations for toxicity. Overall, Cirm did not appear to negatively impact the safety of Ibr. Efficacy (MCL): As of the 02FEB2021 efficacy cutoff, the best response of 17 evaluable pts in Parts 1 and 2 included an objective response rate (ORR) of 82%, 41% CR/CMR, 41% PR, 12% SD, and 6% PD. CR/CMR remain durable from 8-28+ mos. Most responses occurred rapidly after ̃3 mos of Cirm/Ibr. Notably, responses were achieved in all pts who received prior SCT+/- CAR-T (4CR, 1PR) or prior Ibr (2CR, 2PR). At a median follow-up of 14.6 mos, the median PFS (mPFS) had not been reached (NR) (95% CI: 17.5, NA). Efficacy (CLL): The best response of 34 evaluable pts in Parts 1 and 2 included 91% ORR, 3% CR, 88% PR/PR-L, 9% SD, 0% PD. In Part 3, both arms achieved 100% ORR (all PRs). At a median follow-up of 20.2 mos, the mPFS was NR (95% CI: NA, NA), and the PFS estimate at 24 months was 95% for R/R, and 87% for TN, respectively, for evaluable CLL pts receiving Cirm/Ibr. Conclusions: Cirm/Ibr is a well-tolerated, active regimen in both MCL and CLL. For MCL, the mPFS of NR (95% CI: 17.5, NA) and CRR (41%), with all CRs remaining without PD, compare favorably to mPFS of 12.8 mos (95% CI 8.5-16.6) and CRR (20%) reported for single agent Ibr (Rule 2017). For CLL, the high ORR and PFS are encouraging, particularly for RR CLL. The study is ongoing, with MCL enrollment expanded to study Cirm + Ibr in pts who have had a suboptimal response to an Ibr regimen, or who have failed other approved BTKi agents. Clinical trial information: NCT03088878.

294 Background: A recent ph3 study combining bevacizumab (VEGF-A Mab) with atezolizumab (PD-L1 inhibitor) has shown significant improvements in OS and PFS demonstrating that a combination of VEGF and PDL1 inhibition can improve patient outcomes over sorafenib. Tivozanib (T, a potent and selective VEGFR 1, 2 & 3 TKI) and durvalumab (D, a PD-L1 antibody) have both demonstrated single agent activity in HCC and have been combined safely with other therapies. T blocks all three VEGF receptors, and when combined with a PD-L1 inhibitor may improve patient outcomes. The ph1 portion of this study combines T with D to establish the recommended phase II dose (RP2D) and provide preliminary safety and efficacy data. Methods: Major eligibility criteria are adults with documented advanced HCC, Child-Pugh Class A, ECOG 0 or 1, creatinine clearance > 40 ml/min. Major exclusion criteria are co-infection with HBV and HCV and significant organ dysfunction. The starting dose is the combination of T 1 mg orally for 21 days followed by 7 days off treatment and D 1500 mg intravenously every 28 days. A DLT is generally defined as the occurrence of any Grade ≥3 immune or non-immune adverse event (AE) in Cycle 1 that is at least possibly related to the investigational regimen other than any grade of vitiligo or alopecia or Grade 3 controllable hypertension in cycle 1. The primary objective is to establish the RP2D and the safety and tolerability for this combination in patients with advanced HCC. Patients will be treated until progression of disease, unacceptable side effects, or death. Outcome measures will be AEs per CTCAE v.5 and cross-sectional imaging performed every 8 weeks. Results: Seven patients were enrolled in phase I. Six were male; the median age was 75 (range 40 to 82). One patient had mild elevation of LFTs and did not complete the 21-day course of T and was replaced. No patient experienced a >=grade 3 AE in cycle 1. The most common AEs, each seen in two of seven patients, were anorexia, cough, diarrhea, dysphonia, fatigue, hypertension, and palmar-plantar erythrodysesthesia. Two of seven have achieved a partial response. Conclusions: The combination of T with D in patients with untreated advanced HCC is well tolerated. The RP2D for the combination is T 1 mg orally for 21 days on treatment followed by 7 days off treatment and D 1500 mg intravenously every 28 days. In the phase II portion of the study an additional 30 patients will be treated at the RP2D. Secondary objectives are to assess the objective response rate, progression free survival, and overall survival in this population. Clinical trial information: NCT03970616.

Abstract Langerhans-cell histiocytosis (LCH) results from the accumulation of tissue histiocytes derived from the same progenitor cells as monocytes. Because cladribine is potently toxic to monocytes, we conducted a phase II trial of cladribine. Cladribine was administered to 13 LCH patients at 0.14 mg/kg per day by 2-hour intravenous infusion for 5 consecutive days, every 4 weeks for a maximum of six courses. Median age was 42 years (range, 19 to 72) and median pretreatment disease duration was 99 months (range, 6 to 252). One patient was untreated, one had received prior prednisone only, one prior radiation only, six prior radiation and chemotherapy, and four prior surgery, radiation, and chemotherapy. Seven patients had cutaneous involvement, six multifocal osseous, six pulmonary, two each with soft tissue and nodal involvement, and four had diabetes insipidus. Of 13 patients, 12 were evaluable for response and all for toxicity. After a median of three courses (range, 1 to 6), seven (58%) patients achieved complete responses (two pathologic and five clinical) and two (17%) patients achieved partial responses; overall response rate, 75%. Median response follow-up duration was 33 months (range, 1 to 65). Seven patients experienced grade 3 to 4 neutropenia. Only one patient had a documented infection, dermatomal herpes zoster. At a median follow-up of 42 months (range, 5 to 76), 12 patients remain alive and one patient has died. Thus, cladribine has major activity in adult LCH and warrants further investigation in both pediatric and adult LCH as a single agent and in combination with other drugs.

7504 Background: Bortezomib is effective in relapsed and/or refractory MM. This trial evaluated its efficacy and safety as monotherapy in previously untreated MM. Methods: Pts with untreated, symptomatic MM were eligible, with pts receiving concomitant steroids, platelet count < 30 × 109/L, or grade > 2 peripheral neuropathy [PN] excluded. Endpoints included response rate (RR) [Bladé criteria], time to progression, safety, incidence/severity of PN, and effect of dose modifications on PN. Pts received bortezomib 1.3 mg/m2 (d1, 4, 8, 11 every 21d) for 8 cycles. Comprehensive neurologic evaluation including electrophysiologic testing [NCS] and skin biopsy was performed in a subset of pts (n = 34). Results: Sixty-six pts (47% with stage III MM) were treated and 60 pts are evaluable for response, with an overall RR of 38% (CR 10%, PR 28%). PN was reported in 55% (36/65) pts (23 grade 1, 12 grade 2). One pt with grade 3 PN was discontinued. Other common treatment-associated adverse events reported to date include grade 1–2 fatigue in 21% (6/29), and rash in 17% (5/29) pts. Preliminary analysis shows PN improved or resolved in 75% (6/8 pts, with available follow-up data) with dose reduction. At baseline, small-fiber neuropathy (SFN) was seen in 52% (17/33) and large fiber axonal neuropathy (LFN) occurred in 9% (3/34) pts by NCS. SFN worsened in 41% (7/17) pts with baseline SFN. After completion of treatment, new SFN was seen in 33% (8/24) pts and LFN in 17% (4/24) pts by NCS. Conclusion: Single agent bortezomib is active in newly diagnosed MM pts (CR 10%), has manageable toxicity and offers a steroid-sparing approach. Underlying SFN appears more common in MM than previously appreciated and can also develop during bortezomib therapy, with symptomatic PN improving with dose modification. [Table: see text]

3553 Background: The most relevant recent advance in the treatment of metastatic colorectal cancer is the fact that cure is still possible under very selected conditions. However the goal of chemotherapy remains palliative in the great majority of patients, justifying less toxic innovative approaches in so- called “window of opportunity trials”. We have pursued this idea in a phase II study of cetuximab monotherapy in chemo-naive patients with advanced colorectal cancer beyond any possibility of curative resection. Methods: Patients with non-resectable metastatic colorectal cancer (at least two metastatic sites and/or otherwise inoperable metastatic disease) were treated with cetuximab (400 mg/m2 week 1 and 250 mg/m2 weekly thereafter) until progressive disease (PD) or unacceptable toxicity. The primary end-point was objective response; secondary end-points were: stable disease, time to treatment failure and time to progression. According to Simon’s two-stage design, the number of responses/patients to stop the trial was 0/10 for stage 1 and 3/29 for stage 2. Results: Of the 44 patients screened, 42 (97%) had EGFR-expressing tumors. Thirty-nine patients (median age: 69) initiated the treatment. Two had grade 3 allergic reactions to cetuximab at the first administration leading to treatment discontinuation. The most common adverse event was skin toxicity, which occurred in 90% of the patients ( 31% grade 2, 10 % grade 3). We observed 1 complete response, 3 partial responses, 13 stable diseases (5 of which were minor responses), and 22 PD. The duration of the 4 responses were 12, 9, 9 and 6 months. Median time to progression was 2.0 months. Conclusions: The study is negative because the response rate is low. However, the duration of benefit in the few responding patients is such that it is imperative to find the molecular determinants of cetuximab activity in these cases. [Table: see text]

9507 Background: Brain metastases (BMts) are a major cause of morbidity/death in MEL. We report the first efficacy data in MEL patients (pts) with BMts who received NIVO+IPI in study CheckMate 204. Methods: In this multicenter US trial (NCT02320058), MEL pts with ≥1 measurable BMt 0.5-3.0 cm and no neurologic symptoms or steroid Rx received NIVO 1 mg/kg + IPI 3 mg/kg Q3W x 4, then NIVO 3 mg/kg Q2W until progression or toxicity. Pts with severe adverse events (AEs) during NIVO+IPI could receive NIVO when toxicity resolved; stereotactic radiotherapy (SRT) was allowed for brain oligo-progression if an assessable BMt remained. The primary endpoint was intracranial (IC) clinical benefit rate (complete response [CR] + partial response [PR] + stable disease [SD] > 6 months). The planned 90-pt accrual is complete; we report efficacy and updated safety for 75 pts with disease assessment before the Nov 2016 database lock. Results: Median age was 59 yrs (range 22–79). Median number of induction doses was 3; 26 pts (35%) received 4 NIVO+IPI doses and 38 pts (51%) began NIVO maintenance. Response data are reported at a median follow-up of 6.3 months (Table). The IC objective response rate (ORR) was 56% (95% CI: 44–68); 19% of pts had a complete response. IC and extracranial responses were largely concordant. Rx-related grade 3/4 AEs occurred in 48% of pts, 8% neurologic, including headache and syncope. Only 3 pts (4%) stopped Rx for Rx-related neurologic AEs. One pt died of immune-related myocarditis. Conclusions: In CheckMate 204, prospectively designed to investigate NIVO+IPI in MEL pts with BMts, NIVO+IPI had high IC antitumor activity with objective responses in 56% of pts, CR in 19%, and no unexpected neurologic safety signals. The favorable safety and high anti-melanoma activity of NIVO+IPI may represent a new Rx paradigm for pts with asymptomatic MEL BMts and could change practice to avoid or delay whole brain RT or SRT. Clinical trial information: NCT02320058. [Table: see text]

Abstract Background: Copanlisib is a novel pan-Class I phosphatidylinositol-3-kinase (PI3K) inhibitor with potent preclinical inhibitory activity against both PI3K-d and PI3K-α isoforms. Preliminary results from a phase II study of copanlisib in patients with relapsed/refractory non-Hodgkin lymphoma (NHL) or chronic lymphocytic leukemia (CLL) have been reported (Dreyling et al., ASH 2013), with an expansion cohort for patients with aggressive lymphoma still ongoing. We report here the final results of this exploratory study for patients with indolent NHL or CLL treated with copanlisib. Methods: Patients with histologically confirmed indolent NHL or CLL and relapsed or refractory to ≥2 prior lines of treatment were eligible. Copanlisib was administered at a dose of 0.8 mg/kg as a 1 hour intravenous infusion on days 1, 8 and 15 of a 28-day cycle until disease progression or unacceptable toxicity. The primary endpoint was objective response rate (ORR) as assessed per independent radiologic review according to the response criteria for lymphoma (Cheson et al., JCO 17:1244,1999) or the guidelines for diagnosis and treatment of CLL (Hallek et al., Blood 111:5446-56, 2008). Secondary endpoints included progression-free survival (PFS) and duration of response (DOR), safety and tolerability. Results: A total of 33 patients were treated in the indolent group, including: follicular NHL (FL) = 16, CLL = 13, marginal zone lymphoma (MZL) = 3, and small lymphocytic lymphoma (SLL) = 1. Median age was 68 years (range 46-89), M/F= 15/18. The median number of previous lines of treatment was 4. Thirty patients (91%) were previously exposed to rituximab. The median number of cycles received was 5.7 (mean 7.2); the median dose and median cumulative dosage of copanlisib administered were 52 mg (87% of planned dose) and 687 mg, respectively. Five patients were dose reduced to 0.6 mg/kg and 1 to 0.4 mg/kg. The ORR as determined by independent radiologic review in 32 evaluable patients was 47%, with 1 CR, 1 uCR, and 13 PRs. By histology, there were 1 CR, 1 uCR and 5 PRs for patients with FL (ORR 47%), and 2/3 PRs for patients with MZL and 1/1 PR for the patient with SLL, for an overall ORR for patients with indolent NHL (excluding CLL) of 53%. The ORR for patients with CLL was 38% (all PRs). Overall, the median DOR was 287 days (95% CI: 56; not yet reached); median PFS was 240 days (95% CI: 173; 419). The most common adverse events (AEs) of all grades were hyperglycemia (70%), hypertension (70%), fatigue (64%), diarrhea (36%), neutropenia (36%) and anemia (33%). Grade 3-4 AEs occurring in >10% of patients included: hypertension (49% grade 3), neutropenia (30%), hyperglycemia (30% grade 3), and anemia (15%). Dose reductions, interruptions, or permanent discontinuations due to AEs were reported in 4 (12%), 21 64%), and 11 (33%) patients, respectively. There was one drug-related grade-5 event; meningitis in a heavily-pretreated CLL patient with longstanding disease-related immunodeficiency, occurring shortly after first administration of copanlisib. Conclusions: Copanlisib is active as a single-agent in heavily pretreated, advanced refractory/relapsed FL, MZL, SLL, and CLL. Copanlisib exhibited an acceptable toxicity profile, consistent with previous reports. Based on the results of this exploratory study, a phase 2B study of copanlisib in relapsed or refractory indolent NHL (after prior treatment with an alkylating agent and rituximab) has been initiated and is ongoing.

8037 Background: Previous biochemotherapy (BCT) regimens for metastatic melanoma have utilized lower doses of IL-2 and multiple chemotherapeutic agents, adding to toxicity, but not to efficacy. Methods: We designed a 2-stage Simon phase II study testing a unique BCT approach of single agent chemotherapy with TMZ given in an extended schedule (75 mg/m² per day for 3 weeks PO) followed by HDB IL-2 (600,000 U/Kg/dose, maximum 14 doses administered over 5 days). Cycles were repeated every 28 days with a two-week interval between alternate cycles. The first stage accrued 20 patients with promising activity and safety permitting enrollment of additional patients. Results: Thirty-one patients (20 male, 11 female), age 27–74 (median 47) have been enrolled to date. All had AJCC stage IV melanoma (7 M1a, 5 M1b, 19 M1c) and had not previously received therapy for metastatic disease. Twelve had received prior adjuvant interferon. A total of 88 cycles of therapy have been administered (median of 2 cycles per patient; 5 patients continue on therapy). The median number of doses was 9 (range 7–12) during cycle 1, and 6 (range 4–11) during cycle 2. Three patients did not receive any IL-2 due to disease progression, and 6 patients received only one cycle of IL-2. Twenty two patients who received at least 2 cycles are evaluable for response. All 31 patients are evaluable for toxicity. Grade 3 toxicities included hepatic (8), hematologic (4 leukopenia, 2 thrombocytopenia), diarrhea (1). No grade 3–4 cardiovascular or renal toxicities were noted. Overall response rate is 22.7% (2 complete lasting 10.8 and 17+ months, 3 partial lasting 3.7 and 16+ months, 1+ month). Responses were seen in both M1a and M1c disease. Fourteen patients had stable disease after 2 cycles and 10 of these have progressed. As of 12/31/2005, the 4 month PFS rate is 74% [40%, 88%], median TTP is 24 weeks [11, 32] and median OS is 71 weeks (31.4, inf). Conclusions: HDB IL-2 can be safely administered in combination with single agent temozolomide in an extended schedule and appears to have promising efficacy and lower toxicity than previously used BCT regimens. Further follow-up will determine if durability of response exceeds that of single agent HDB IL-2. [Table: see text]

Phase I study cohort evaluating an optimized administration schedule of SAR3419, an anti-CD19 DM4-loaded antibody drug conjugate (ADC), in patients (pts) with CD19 positive relapsed/refractory b-cell non-Hodgkin’s lymphoma (NCT00796731).

Optimized Schedule

8057 Background: The recommended dose (RD) of SAR3419 administered intravenously every 3 weeks (q3w) for 6 cycles is 160 mg/m2 and is 55 mg/m2 when administered weekly (q1w) for 8-12 doses. Reversible corneal deposits were dose limiting (DLT) in the q3w schedule. The q1w schedule was well tolerated and active. However, based on the occurrence of late/cumulative adverse events (AE) at the RD supported by pharmacokinetic (PK) analyses showing ADC plasma accumulation after 4 weekly doses, an optimized schedule consisting of 4 weekly doses followed by 4 bi-weekly doses at the RD was tested. Methods: The q1w study was extended to treat 25 pts with the optimized schedule for 8 to 12 doses. Results: Twenty-one pts were evaluable. Main histologies were diffuse large B-cell (DLBCL) (9; 43%) and follicular (6; 29%). Median number of prior regimens was 2 [1-8], 6 pts received prior autologous transplantation and 95% of pts were Ann Arbor stage III-IV at study entry. Median number of doses received was 8 as planned with a median relative dose intensity of 1.0 [0.8-1.0]. Most frequent AEs were asthenia (1 pt with grade 3) and gastrointestinal disorders in 7 pts each. No AE fulfilled the defined DLT criteria. Reversible grade 1 blurred vision/corneal event occurred in 1 pt. Grade 3-4 haematological toxicities were minor consisting of non complicated neutropenia in 4 pts, thrombocytopenia in 2 pts and anemia in 1 pt with no transfusion support. Six (29%) pts, among them 3 with DLBCL, achieved an objective response including 3 CRu (1 in a pt refractory to last regimen). In addition, 9 (43%) pts had stable disease. Response duration was [8-35+] weeks, 5 pts still responding at the cut-off date. Conclusions: The optimized administration schedule shows an improved safety profile compared to prior tested schedules. The clinical efficacy is preserved essentially in aggressive lymphoma. The optimized schedule is being assessed in 2 phase II studies evaluating SAR3419 either as a single agent or in combination with rituximab in pts with DLBCL histology.
