Unmet Need

TPS8054 Background: Despite recent advances in treatment, multiple myeloma (MM) remains incurable in most patients. The standard of care for MM includes combinations of agents with different mechansims of action, e.g. proteasome inhibitors (PIs), immunomodulatory drugs (IMiDs), monoclonal antibodies, alkylating agents, and corticosteroids. Sequential lines of treatment typically yield shorter durations of disease control with each subsequent relapse. Frail patients face a particularly high unmet need, given the toxicity profiles of many agents. SEA-BCMA is a humanized non-fucosylated IgG1 monoclonal antibody targeting BCMA, a plasma cell-specific protein that is expressed on MM cells of most patients. Based on preclinical data, SEA-BCMA displays enhanced antibody dependent cellular cytotoxicity through increased FcγRIII binding, antibody dependent cellular phagocytosis, and blocking of BCMA-mediated pro-survival and proliferative signaling. SEA-BCMA is active at 0.03 mg/kg in xenograft models and does not cause adverse effects in preclinical models, supporting clinical investigation for MM. Methods: This is a phase 1, open-label, multicenter, dose-escalation study to evaluate the safety, tolerability, and antitumor activity of SEA-BCMA in adults with relapsed/refractory MM. Enrollment began in November 2018 for adults aged ≥18 years with histologically confirmed MM, Eastern Cooperative Oncology Group performance status of ≤1, and no other therapeutic options available. Prior therapies must include a PI, an IMiD, and an anti-CD38 antibody. Prior receipt of BCMA targeted agents is prohibited. BCMA expression is not required for study entry, but will be tested retrospectively. Dose-escalation is being conducted in ~25 subjects using the modified toxicity probability interval method. During dose-expansion, ~40 subjects will be treated at the maximum tolerated or optimal dose. Responses are assessed per the 2016 International Myeloma Working Group criteria. Biomarker and pharmacokinetic evaluations will be performed on peripheral blood and bone marrow. Clinical trial information: NCT03582033.

Treatment Patterns

414 Background: There are a lack of published real-world data on treatment patterns for patients with locally advanced or metastatic urothelial carcinoma (la/mUC) previously treated with programmed death 1/ligand 1 inhibitor (PD-1/L1i) therapy. The objective of this study was to characterize the clinical characteristics and treatments among patients with la/mUC following discontinuation of first-line (1L) or second-line (2L) PD-1/L1i therapy. Methods: We performed a retrospective chart review at 26 geographically diverse clinical sites in the US. Patients aged ≥18 years with histologically or cytologically confirmed urothelial carcinoma and radiographic evidence of metastatic or locally advanced disease were identified. Included patients had initiated and subsequently discontinued PD-1/L1i therapy in the 1L or 2L setting for la/mUC between May 15, 2016-July 31, 2018. All patients had follow-up through October 31, 2019. Data were summarized using descriptive statistics. Results: Among the 300 patients included in the chart review, 198 (66%) received PD-1/L1i therapy as 1L and 102 (34%) as 2L therapy. Mean (SD) age at la/mUC diagnosis was 69.4 (8.7) years, and a majority of patients were male (66.0%) and White (74.7%). Consistent with age, most patients (82.7%) had comorbidities at la/mUC diagnosis; 39.7% hypertension, 23.7% coronary artery disease, 17.7% pulmonary disease, and 9.3% renal disease. At initiation of therapy, a higher proportion of patients who received 1L PD-1/L1i therapy had an Eastern Cooperative Oncology Group performance status of 2 or more than patients who received 2L PD-1/L1i therapy (36.8% vs 22.5%, respectively). Following discontinuation of PD-1/L1i therapy, 34% (n = 68) received subsequent therapy in 2L and 29% (n = 30) in third-line (3L). The most common subsequent therapies in 2L were gemcitabine monotherapy (24%), gemcitabine plus cisplatin or carboplatin (22%), PD-1/L1i therapy (22%), and taxane monotherapy (19%). The most common subsequent therapies received in 3L were taxane monotherapy (50%), pemetrexed (17%), and PD-1/L1i therapy (16%). Overall, switching from one PD-1/L1i therapy to another distinct PD-1/L1i therapy occurred in approximately 20% of patients, with “better efficacy/survival” noted by treatment teams as the most common reason for switching therapy among this subgroup. Conclusions: In this real-world case series, only a minority of patients with la/mUC who discontinued PD-1/L1i therapy received subsequent therapy. Among those that did, no clear standard of care was observed and approximately one-fifth of patients were treated with a second PD-1/L1i therapy after the first failed to control disease. Collectively, the data highlight significant unmet need for patients with la/mUC who discontinue PD-1/L1i therapy.

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. An 84-year-old woman presented with bone pain and lytic bone lesions in April 2010. Diagnosis of multiple myeloma was based on the presence of an immunoglobulin G lambda serum M protein (4,784 mg/dL) and confirmed by the findings of bone marrow plasma cell infiltration, with t(11;14) chromosomal abnormality detected by fluorescence in situ hybridization analysis. The patient’s medical history was significant for hypertension; she had an Eastern Cooperative Oncology Group performance status of 1, International Staging System (ISS) stage of 1, and Durie–Salmon stage of IIIA. In May 2010, the patient was enrolled in a randomized phase III trial comparing different lenalidomide-based treatments and received induction with lenalidomide plus dexamethasone (nine cycles) followed by lenalidomide maintenance. The patient started treatment with lenalidomide 25 mg per day for 21 days and reduced-dose dexamethasone 20 mg per week per protocol because of age. Induction was well tolerated; no relevant complications occurred, except for grade 1 fatigue and grade 1 diarrhea. Best response was partial response. In March 2011, she started maintenance with lenalidomide 10 mg per day. A dose reduction of lenalidomide 5 mg per day was required because of grade 2 diarrhea. In July 2015, the patient experienced relapse, with painful collapse of L3 vertebral body.

Abstract Background: CP-751,871, a fully human IgG2 subtype monoclonal antibody, is a potent and specific inhibitor of the insulin- like growth factor type I receptor (IGF-IR). The IGF-IR regulates the growth, survival, adhesion and invasiveness of multiple myeloma cells. High IGF-IR expression is observed in poor-prognostic subtypes of multiple myeloma and its inhibition has been long proposed as a potential therapeutic approach for treatment of this disease. Methods: A phase 1 dose escalation study was conducted to define the safety and tolerability, and to characterize the pharmacokinetic and pharmacodynamic (granulocyte surface IGF-IR expression and serum IGF-I levels) properties of CP-751,871 in patients with multiple myeloma. Patient’s eligibility included previously treated multiple myeloma in relapse or refractory phase including those less than complete remission to autologous stem cell transplant or tandem transplant. Results: Following informed consent and screening, 47 patients were enrolled into 11 dose-escalation cohorts of CP-751,871 at doses from 0.025 to 20 mg/Kg. Median patient age was 60 years. Median number of previous regimens was 4 (range 1–8). CP-751,871 was given as an IV infusion on Day 1 of 4-week cycles. Patients with a suboptimal response to CP-751,871 alone were eligible to receive CP-751,871 in combination with either oral dexamethasone and/or rapamycin at the discretion of the investigator. Twenty-seven patients received CP-751, 871 in combination with dexamethasone, while four patients received rapamycin in combination with either CP-751,871 or CP-751,871 and dexamethasone. Median number of treatment cycles was 3 (range 1–16). Ten patients were dosed at the highest cohort of 20 mg/Kg. No CP-751,871 related dose limiting toxicities were identified. Grade 3 toxicities were all observed at the 20 mg/Kg cohort (1 hyperglycemia, 1 anemia, 1 AST increase, 1 accidental fall, 1 muscle weakness). Plasma CP-751,871 exposure increased with dose, and the pharmacokinetic characteristics were consistent with target-mediated disposition. Granulocyte IGF-IR expression was maximally down-regulated for the entire duration of the dosing period at doses ≥1.5 mg/kg, indicating a saturation of circulating targets. CP-751,871 also led to a dose-dependent increase in circulating IGF-I concentrations. Tumor response was assessed according to Blade criteria. Two remissions and 4 partial remissions were reported in patients treated with different doses of CP-751,871 in combination with dexamethasone. Interestingly, the 2 patients with remission were previously found to be refractory to dexamethasone treatment. Conclusions: These data indicate that CP-751,871 is well tolerated either as a single agent or in combination with dexamethasone. Furthermore, CP-751,981 in combination with dexamethasone, may constitute a novel and effective therapeutic approach for patients with multiple myeloma.

Bispecific T Cell Engager

TPS2071 Background: GBM is the most aggressive primary brain tumor in adults and is extremely difficult to treat. Patients with GBM tend to progress rapidly within weeks or months. Median overall survival is only 12–15 months despite aggressive treatment, and less than 5% of patients survive 5 years. GBM also severely impacts quality of life and cognitive function. Approximately 50% of GBM tumors test positive for amplification or mutation of the epidermal growth factor receptor (EGFR), the most common of which is the EGFRvIII gain-of-function mutation. AMG 596 is a bispecific T cell engager (BiTE®) antibody construct designed to crosslink and engage CD3-positive T cells to EGFRvIII-positive tumor cells, inducing tumor cell lysis and T cell proliferation. A clinical trial is being conducted for this novel immunotherapy agent in patients with EGFRvIII-positive GBM. Methods: NCT03296696 is a phase 1, first-in-human, open-label, sequential dose-escalation and dose-expansion study evaluating the safety, tolerability, and pharmacokinetics and pharmacodynamics (PK/PD) of AMG 596 in patients with EGFRvIII-positive GBM. AMG 596 is administered via continuous intravenous infusion. The study is expected to enroll approximately 82 patients total and comprises two groups (Group 1: patients with recurrent GBM; Group 2: patients with newly diagnosed GBM in the maintenance treatment phase after standard of care). Key inclusion criteria include: male or female; ≥ 18 years of age; with pathologically documented and diagnosed grade IV GBM; Eastern Cooperative Oncology Group performance status ≤ 1; life expectancy ≥ 3 months per study investigator; and acceptable renal, hematological, and hepatic function. The primary endpoint evaluates the safety and tolerability of AMG 596 via collection of treatment-emergent adverse events. Additional endpoints include objective response rate per modified Response Assessment in Neuro-Oncology Criteria and PK/PD analyses of AMG 596 in serum. The study began enrolling patients in April 2018 and enrollment is ongoing. For more information, please contact Amgen Medical Information: [email protected]. Clinical trial information: NCT03296696.

Tyrosine Kinase Receptor

TPS9628 Background: Mesenchymal-epithelial transition (MET) factor is a transmembrane tyrosine kinase receptor activated by hepatocyte growth factor (HGF). Aberrant activation of MET via gene amplification or gene mutations, as well as MET protein overexpression, has been reported in NSCLC and other cancer types and can promote tumorigenesis. REGN5093 is a human bispecific antibody that binds to two distinct epitopes of MET, blocking HGF binding and inducing internalization and degradation of MET. REGN5093 prevents MET-mediated signaling and inhibits growth of MET-driven tumor cells without inducing MET-driven biological responses (DaSilva et al, CCR, 2019; PMID: 31848185). Methods: This Phase I/II, first-in-human, multicenter study is investigating the safety, tolerability, pharmacokinetics (PK), and efficacy of REGN5093 in patients with MET-altered advanced NSCLC who have received all available approved therapies (NCT04077099). Key eligibility criteria include age ≥18 years, Eastern Cooperative Oncology Group performance status of ≤1, and documented presence of either MET exon 14 gene mutation and/or MET gene amplification and/or elevated MET protein expression. Patients are required to provide a biopsy during screening for assessment of MET biomarkers. Key exclusion criteria include prior MET-targeted biologic therapy (expansion cohorts only). Prior therapy with tyrosine kinase inhibitors are not exclusionary in any part of the study. For each patient, the study comprises a screening period of up to 28 days, followed by 3-week cycles of REGN5093 monotherapy. Study treatment will continue until confirmed disease progression or other protocol-defined reason for discontinuation. The study has two parts: dose escalation and dose expansion. Dose escalation will proceed via 4+3 design until a maximum-tolerated dose is reached or a recommended Phase II dose selected. The primary objective of the dose escalation part is to assess safety (incidence and severity of adverse events and Grade ≥3 laboratory abnormalities), tolerability (incidence of dose-limiting toxicities), and PK of REGN5093. During the expansion phase, patients will be allocated to cohorts according to the type(s) of documented biomarkers of MET-altered disease. Anti-tumor activity based on objective response rate per Response Evaluation Criteria in Solid Tumors version 1.1, determined by CT or MRI, will be the primary endpoint in the expansion cohorts. The study is currently open for enrollment. Clinical trial information: NCT04077099 .

Purpose PF-00562271 is a novel inhibitor of focal adhesion kinase (FAK). The objectives of this study were to identify the recommended phase II dose (RP2D) and assess safety and tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and antitumor activity of PF-00562271. Patients and Methods Part 1 was a dose escalation without and with food. Part 2 enrolled specific tumor types in an expansion at the RP2D and also assessed the effect of PF-00562271 on single-dose midazolam PK in a subgroup of patients. Results Ninety-nine patients (median age, 60 years; 98% with Eastern Cooperative Oncology Group performance status of 0 or 1) were treated in 12 fasting and three fed cohorts. The 125-mg twice-per-day fed dose was deemed the maximum-tolerated dose (MTD) and RP2D. Grade 3 dose-limiting toxicities included headache, nausea/vomiting, dehydration, and edema. Nausea was the most frequently observed toxicity (60% of patients, all grades 1 or 2 at RP2D). PF-00562271 exposure increased with increasing dose; serum concentration–time profiles showed characteristic nonlinear disposition. Steady-state exposures were reached within 1 week. On coadministration, geometric mean values of midazolam maximal observed serum concentration and area under the serum concentration–time curve increased by 60% and more than two-fold, respectively. Of 14 patients evaluable by [18F]fluorodeoxyglucose positron emission tomography in the expansion cohorts, seven metabolic responses were observed. With conventional imaging, 31 patients had stable disease at first restaging scans, and 15 of these remained stable for six or more cycles. Conclusion The MTD and RP2D of PF-00562271 is 125 mg twice per day with food. PF-00562271 displayed time- and dose-dependent nonlinear PK and is likely a potent CYP 3A inhibitor. This first-in-class study supports further investigation of FAK as a promising therapeutic target.

Anti Tumor Activity

TPS2671 Background: MERTK is a receptor tyrosine kinase from the tumor-associated macrophage kinase (TAMK) family that regulates key aspects of immune homeostasis and responses to infection. MERTK inhibition may lower the threshold for immune activation thereby promoting anti-tumor activity. Agents with some degree of MERTK inhibitory activity have been investigated in the clinic, but are limited by poor potency in patients (pts) and significant off-targets effects. PF-07265807 (ARRY-067) is a selective small-molecule inhibitor of the TAMKs MERTK and AXL. In preclinical models, PF-07265807 monotherapy shows antitumor activity that results in long-term cures and resistance to tumor re-challenge when combined with anti-programmed cell death protein 1/programmed death-ligand 1 (anti-PD-1/PD-L1) antibodies. This first-in-human study will evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity of PF-07265807 in pts with selected advanced or metastatic solid tumors. This study will also explore the potential utility of PF-07265807 in combination with anti-PD-1/PD-L1 antibodies. Methods: This is a phase 1, open-label, multi-center, dose-escalation study (NCT04458259) to evaluate the safety, PK and tolerability of PF-07265807. Eligible participants will be adult pts with selected advanced or metastatic solid tumors who are intolerant or resistant to standard therapy. Other key eligibility criteria: measurable disease by RECIST 1.1 or non-measurable disease; Eastern Cooperative Oncology Group performance status 0–2; adequate bone marrow, renal and liver function; and resolved acute effects of any prior therapy. Successive cohorts of pts will receive escalating doses of PF-07265807 starting from 25 mg QD. Each cycle will be 21 days in duration (14 days on/7 days off). Study drug treatment will continue until disease progression or unacceptable toxicity, whichever occurs first. For dose escalation, a Bayesian logistic regression model will be used to model the relationship of dose-limiting toxicities (DLTs) to PF-07265807 dose. This model, along with escalation with overdose control, will guide the dose escalation of PF-07265807 after the completion of the DLT observation period (first two cycles of treatment, i.e. 42 days) of each cohort, until determination of the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D). After the MTD/RP2D is identified, the safety and efficacy of combined PF-07265807 and anti-PD1/PD-L1 treatment will be explored. Primary endpoints: incidence of DLTs, treatment-emergent adverse events and laboratory abnormalities. Secondary endpoints: PK parameters of PF-07265807, objective response rate and duration of response. The study began enrolling pts in September 2020 and is still recruiting. Clinical trial information: NCT04458259.

TPS3153 Background: Ataxia telangiectasia and Rad3-related (ATR) protein kinase plays a critical role in the DNA damage response by sensing and responding to DNA replication stress, and by inducing cell cycle arrest to prevent aberrant replication and mitotic catastrophe. Based on extensive preclinical and limited clinical evidence, ATR inhibition is a promising treatment strategy as monotherapy for patients with advanced tumors harboring synthetically lethal conditions, such as alternative lengthening of telomeres (ALT) and inactivating mutations in ARID1A and ATM. M1774 is a potent, selective, orally administered ATR inhibitor that has been shown to exert antitumor activity in patient-derived xenograft tumors and acute myeloid leukemia xenograft tumors that express the ATR inhibition sensitizing mixed lineage leukemia fusion protein. This study (NCT04170153) aims to evaluate the safety and tolerability, maximum tolerated dose, recommended dose for expansion (RDE) and pharmacokinetics (PK) of M1774 (part A1), the effect of food on M1774 PK (part A2), and the efficacy of M1774 in patients with tumors harboring selected mutations (part A3). An additional objective is to assess the pharmacodynamics of M1774 by measuring relative changes in baseline p-CHK1 and γ-H2AX expression in paired tumor biopsies and serial blood samples. Methods: Patients aged ≥18 years, with an Eastern Cooperative Oncology Group performance status ≤1, adequate baseline hematological, renal and hepatic function, and with locally advanced or metastatic disease refractory to standard therapy are eligible. Patients with tumors bearing loss-of-function (LoF) mutations (determined by site testing or a central trial assay) in ARID1A, ATM, or ATRX and/or DAXX as ALT status surrogate markers; and measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, will be enrolled in part A3. In the dose escalation phase (part A1 [open]), 18–24 patients are due to receive M1774 at a starting dose of 5 mg once daily. Dose escalation is determined by the safety monitoring committee and guided by a Bayesian 2-parameter logistic regression model. The preliminary food assessment (part A2) will follow a randomized two-sequence two-period crossover design in which ≤12 patients will be randomized (1:1) to receive a single dose of M1774 on Day –7 at the RDE (determined in part A1) in either a fed or fasted condition. After the food assessment, patients will subsequently receive M1774 according to the part A1 dosing schedule. In the preliminary efficacy study (part A3), patients (n = 20–24 for each of the three planned cohorts) with tumors harboring LoF mutations in the genes for ARID1A, ATM, ATRX and/or DAXX, will receive M1774 at the RDE. The primary efficacy endpoint is overall response (RECIST). The study is open and currently recruiting. Patients have been enrolled to seven cohorts in part A1 with no DLTs observed; dose escalation is ongoing. Clinical trial information: NCT04170153.

Abstract Background: The phase 3 OPTIMISMM（NCT01734928） trial done at 133 hospitals and research centres in 21 countries but no Chinese site involved in this study. In the OPTIMISMM study ,pomalidomide, bortezomib, and dexamethasone (PVd) demonstrated excellent efficacy in patients at first relapse, including immediately after upfront lenalidomide treatment failure and other common first-line treatments, the mPFS was 20.73 months, the ORR was 90.1%, and no new safety signals were observed. Building on these promising results, we decided to explore PVd in Chinese patients at first relapse. Study Design/Methods: This is a multicenter, prospective, single-arm phase 2 study designed to evaluate the efficacy and safety of PVd in Chinese patients at first relapse. Eligible patients were aged ≥18 years and had a diagnosis of multiple myeloma, measurable disease, and an Eastern Cooperative Oncology Group performance status of 0-2. Patients were required to have had only 1 prior antimyeloma regimen. Key exclusion criteria included creatinine clearance<30 mL/min requiring dialysis, grade ≥3 peripheral neuropathy, or grade 2 peripheral neuropathy with pain. Patients with prior exposure to bortezomib were eligible, provided they were not refractory to a bortezomib-containing regimen dosed at 1.3 mg/m 2 twice weekly. Patient（n=62,Figure 1）will receive pomalidomide 4 mg on days 1-14 of each cycle. Bortezomib 1.3 mg/m 2 on days 1, 4, 8, and 11 of cycles 1-8 and on days 1 and 8 of cycles 9 and beyond. Dexamethasone was given on days 1, 2, 4, 5, 8, 9, 11, and 12 of cycles 1-8 and on days 1, 2, 8, and 9 of cycles 9 and beyond; patients received 20 mg of dexamethasone if aged ≤75 years and 10 mg otherwise. The primary endpoint is ORR, the secondary endpoints are≥VGPR, MRD(-) rate, PFS, OS and safety. ORR will be assessed by the International Myeloma Working Group criteria after each cycle until PD. The Kaplan-Meier method will be used to estimate PFS and OS. Safety analysis will be conducted in the safety population, which are composed of all patients who received ≥1 dose of study medication. The trial is currently enrolling and will be open in 7 sites of China. Disclosures: Research Sponsor: CHIATAI TIANQING PHARMACEUTICAL GROUP. Figure 1 Figure 1.

AbstractThe number of elderly people is rapidly growing, and the proportion of elderly patients with multiple myeloma (MM) continues to increase. This study aimed to develop a frailty assessment tool based on clinical data and to estimate its feasibility in elderly patients with MM. This study analyzed data from 728 elderly transplant-ineligible patients with newly diagnosed MM who were treated between January 2010 and October 2019. Our clinical frailty index included age (< 75, and ≥ 75 years), Charlson comorbidity index (CCI; < 3 and ≥ 3), and Eastern Cooperative Oncology Group performance status score (ECOG score; 0, 1–2, and ≥ 3). Patients were classified as fit, intermediate, or frail if they had a score of 0, 1, or ≥ 2, respectively. The overall survival rates differed significantly according to frailty (fit vs. intermediate: hazard ratio [HR] = 2.41; 95% confidence interval [CI] = 1.43–4.06; P = 0.001; fit vs. frail: HR = 4.61; 95% CI = 2.74–7.77; P < 0.001 and intermediate vs. frail: HR = 1.91, 95% CI = 1.49–2.45, P < 0.001, respectively). The frail had significantly shorter EFS compared with the fit and intermediate group in our frailty index (fit vs. intermediate: HR = 1.34, 95% CI = 0.92–1.96, P = 0.132; fit vs. frail: HR = 2.06, 95% CI = 1.40–3.02, P < 0.001; and intermediate vs. frail: HR = 1.53, 95% CI = 1.22–1.92, P < 0.001, respectively). The new clinical frailty index, which is based on age, CCI, and ECOG PS, can easily assess frailty in elderly patients with MM and can be helpful in predicting survival outcomes in real world clinical setting.
