2575 Background: TPI 287 is an investigational taxane designed to not be a substrate for mdr-1 and to bind to mutant tubulin. In preclinical studies, TPI 287 demonstrated activity against multiple human tumor xenografts in nude mice, including xenografts that expressed mdr-1 and that were resistant to other taxanes. The safety and tolerability of TPI 287 when administered weekly for 3 weeks followed by a 1 week rest (4 week cycle) was examined in this Phase 1 dose escalation study in patients (pts) with advanced neoplasms. Materials and Methods: TPI 287 was administered over 1 hour weekly for 3 weeks followed by 1 week of no treatment. Treatment cohorts consisted of 3 pts and were expanded to 6 pts in the face of dose-limiting toxicity (DLT); pts could remain on study until the development of progressive disease or an intolerable adverse event. DLT was defined as Gr 4 heme toxicity lasting 7 days; febrile neutropenia, Gr 3 thrombocytopenia with bleeding, Gr 3 elevation of transaminases lasting 7 days or any other Gr 3/4 toxicity other than nausea or vomiting. Results: 25 pts (M:F 16:9, median age 60, range 24 - 86) were enrolled in 7 dose levels ranging from 7–185 mg/m2. Pts’ cancers included colorectal (6 pts); NSCLC (2); prostate (2); squamous cell carcinoma (2) and 1 pt each with cervical, breast, ovarian, gastric, pancreatic, bladder endometrial, NSCLC, SCLC, glioblastoma, melanoma, renal cell and hepatocellular carcinoma. All pts but 1 had received prior chemotherapy (median no. prior treatments: 3 (range, 1–7). Drug related adverse events included nausea, vomiting, diarrhea, fatigue, anorexia, rash, anemia and peripheral neuropathy. 1 pt., who was inadvertently treated with inadequate marrow reserve, experienced Gr 4 neutropenia and died of sepsis. DLT of Grade 3 peripheral neuropathy has been observed. PK data to date reveal that AUC is generally dose linear. At a dose of 127.5 mg/m2, clearance was 30.2 + 11.9 L/hr/m2 and t1/2 8.6 + 1.3 hrs. Results are similar with non-compartmental methods and 2-compartment modeling. Conclusions: TPI 287 can be safely administered in doses of up to 127.5 mg/m2 weekly x 3. No significant financial relationships to disclose.

2569 Background: TPI 287 is a third generation taxane engineered to overcome multi-drug resistance and to bind to mutant tubulin. In preclinical studies, TPI 287 suppressed the growth of multiple human tumor xenografts in nude mice, including xenografts that expressed mdr- 1 and that were resistant to other taxanes. The safety and tolerability of TPI 287 when administered every 21 days was examined in this Phase 1 dose escalation study in patients (pts) with advanced neoplasms. Methods: TPI 287 was administered over 1 hour every 21 days in ascending doses to groups of 3 pts. Treatment cohorts were expanded to 6 pts in the face of dose-limiting toxicity (DLT); pts could remain on study until the development of progressive disease or an intolerable adverse event. DLT was defined as Gr 4 heme toxicity lasting 7 days; febrile neutropenia, Gr 3 thrombocytopenia with bleeding, Gr 3 elevation of transaminases lasting 7 days or any other Gr 3/4 toxicity other than nausea or vomiting. Results: 14 pts (M:F 5:9, median age 58.5, range 49 - 77) were enrolled in 5 dose levels ranging from 56 - 185 mg/m2. Pts’ cancers included colorectal (5 pts), esophageal (2), pancreatic (2), NSCLC (2), breast (2) and ovarian (1). All patients had received prior chemotherapy (median no. prior treatments: 3 (range, 2 - 10). Drug related adverse events included mucositis, vomiting, diarrhea, neutropenia, thrombocytopenia, myalgias and peripheral neuropathy. Only 1 pt. experienced Gr 4 neutropenia. DLT of Gr 3 peripheral sensory neuropathy was observed at a dose of 185 mg/m2. At a dose of 160 mg/m2 no DLT was observed. 1 pt with pancreatic cancer had a confirmed response to TPI 287 that has persisted for 2.5 months and continues as of this writing. PK data reveal that AUC is generally dose linear. At a dose of 126 mg/m2, clearance was 24.7 + 12.2 L/hr/m2 and t1/2 was 10.6 + 7.1 hrs. Conclusions: TPI 287 can be safely administered in a dose of 160 mg/m2 every 21 days. The dose limiting toxicity was Gr 3 peripheral neuropathy. Anti-neoplastic activity was seen in a patient with pancreatic cancer. PK is dose linear and predictable. Several Phase 2 studies of TPI 287 are being planned. No significant financial relationships to disclose.

10036 Background: The safety and preliminary tumor response of a doxorubicin conjugate, INNO-206, was evaluated primarily in patients with metastatic STS who progressed on prior chemotherpy. INNO-206 consists of doxorubicin attached to an acid-sensitive linker that binds covalently to cysteine-34 in circulating albumin. Methods: INNO-206 was administered IV at doses of either 230, 350 and 450 mg/m2 (165, 260 and 325 mg/m2 dox. eq.) every 21 days for up to 8 consecutive cycles. Subsequent dose levels were administered if < 2/5 or 4/8 patients experienced a non-hematological dose-limiting toxicity during Cycle 1. Tumor response was monitored every other month and treatment continued until tumor progression or unacceptable toxicity. Standard safety monitoring was performed and cardiac function was followed periodically using MUGA or cardiac ultrasound. Results: As of January 11, 2012, 25 patients were entered in the study. 21/25 patients had STS of various types. Of the 5 patients treated at 230 mg/m2 INNO-206, 1 subject had grade 3 fatigue and acid reflux. Of the initial 5 patients entered at the 350 mg/m2 dose, no individuals experienced a grade 3 or 4 non-hematological toxicity during cycle 1. 2 patients treated at the 450 mg/m2 dose developed grade 3 oral mucositis during cycle 1. No patient exhibited cardiotoxicity as determined by MUGA or cardiac ultrasound. The MTD was determined to be 350 mg/m2 INNO-206 (260 mg/m2 dox.eq.). 15 more patients were entered at this dose (total of 20 patients). Of the 16 patients with STS, 3 objective partial responses (one of whom received prior doxorubicin) are ongoing as well as 10 patients with stable disease (range 2-7 months). 1 patient had progressive disease at the first evaluation. 2 patients died within the first cycle, one due to progressive disease and the other due to sepsis. Conclusions: INNO-206 is an active drug for the treatment of patients with advanced STS who have failed prior chemotherapy. Cumulative doses of 2000 mg/m2 of doxorubicin equivalents have been achieved, which is over 3 1/2 x the peak cumulative dose of standard doxorubicin. Adverse events are primarily hematological and no cardiotoxicity has been observed.

9515 Background: Fianlimab and cemiplimab are two high-affinity, fully human, hinge-stabilized IgG4 monoclonal antibodies. In a Phase 1 dose escalation study, fianlimab combined with cemiplimab showed an acceptable safety profile and some clinical activity in pts with advanced malignancies. Here, we present safety and clinical activity data from two expansion cohorts of pts with advanced melanoma (anti–programmed cell death/ligand-1 [anti–PD-(L)1] naïve or experienced) who were treated with fianlimab + cemiplimab and had an opportunity for first on-treatment tumor assessment (cut-off date: Jan 4, 2021). Methods: Pts with advanced melanoma who had no prior anti–PD-(L)1 treatment (naïve) or prior anti–PD-(L)1 treatment within 3 months of screening (experienced) received fianlimab 1600 mg + cemiplimab 350 mg by IV infusion every 3 weeks. Tumor measurements were performed every 6 weeks for the first 24 weeks and subsequently every 9 weeks per RECIST v1.1. Results: 48 pts with advanced melanoma were treated with the combination therapy: 33 were anti–PD-(L)1 naïve and 15 were anti–PD-(L)1 experienced (median age: 69 years vs 59 years; male: 66.7% vs 46.7%; Caucasian: 87.9% vs 60%). The safety profile (including immune-related adverse events [AEs]) of fianlimab + cemiplimab combination therapy was similar to that of anti–PD-1 monotherapy with one exception. The rate of adrenal insufficiency, 8.3% (4/48) of pts, is similar to the rate previously observed with anti–PD-1 + anti–cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) combination therapy but higher than that observed with anti–PD-1 monotherapy. Grade ≥3 treatment-emergent AEs (TEAEs) occurred in 35.4% (17/48) of patients; Grade ≥3 serious TEAEs occurred in 22.9% (11/48) of patients; 8.3% (4/48) of patients discontinued treatment due to a TEAE. The most common TEAEs were fatigue (n = 15, 31.3%) and rash (n = 11, 22.9%). By investigator assessment, objective response rate (includes unconfirmed complete [CR] and partial responses [PR]) was 63.6% (3 CRs and 18 PRs) for anti–PD-(L)1 naïve pts and 13.3% (1 CR and 1 PR) for anti–PD-(L)1 experienced pts. Median progression-free survival and median duration of response for the anti–PD-(L)1 treatment naïve cohort have not been reached. Prognostic clinical markers and tumor biomarkers such as expression of LAG-3, PD-L1, and major histocompatibility complex II are being evaluated. Recruitment is ongoing. Conclusions: The safety profile of fianlimab + cemiplimab is similar to that observed with cemiplimab monotherapy and other anti–PD-1s, with the exception of higher rate of adrenal insufficiency. Fianlimab + cemiplimab combination has shown clinical activity for pts with advanced melanoma that is similar to anti–PD-1 + CTLA-4 combination therapy, but with lower demonstrated rates of TEAEs.

Summary LY3023414 is an oral, selective adenosine triphosphate-competitive inhibitor of class I phosphatidylinositol 3-kinase isoforms, mammalian target of rapamycin, and DNA-protein kinase in clinical development. We report results of a 3 + 3 dose-escalation Phase 1 study for twice-daily (BID) dosing of LY3023414 monotherapy in Japanese patients with advanced malignancies. The primary objective was to evaluate tolerability and safety of LY3023414. Secondary objectives were to evaluate pharmacokinetics and to explore antitumor activity. A total of 12 patients were enrolled and received 150 mg (n = 3) or 200 mg (n = 9) LY3023414 BID. Dose-limiting toxicities were only reported at 200 mg LY3023414 for 2 patients with Grade 3 stomatitis. Common treatment-related adverse events (AEs) across both the dose levels included stomatitis (75.0%), nausea (66.7%), decreased appetite (58.3%), diarrhea, and decreased platelet count (41.7%), and they were mostly mild or moderate in severity. Related AEs Grade ≥ 3 reported for ≥1 patient included anemia, stomatitis, hypophosphatemia, and hyperglycemia (n = 2, 16.7%). Two patients discontinued due to AEs (interstitial lung disease and stomatitis). No fatal events were reported. The pharmacokinetic profile of LY3023414 was characterized by rapid absorption and elimination. Five patients had a best overall response of stable disease (150 mg, n = 3; 200 mg, n = 2) for a 55.6% disease control rate. LY3023414 up to 200 mg BID is tolerable and safe in Japanese patients with advanced malignancies.

Abstract Background Immunomodulatory drugs (IMiD), such as thalidomide and lenalidomide (LEN) and its newest derivative pomalidomide (POM), have shown great promise for the treatment of multiple myeloma (MM) patients (pts). POM has in vitro anti-MM potency and has shown efficacy for the treatment of relapsed/refractory (RR) MM pts. POM with dexamethasone (DEX) induces responses even for MM pts who are refractory to bortezomib (BORT) and LEN (Richardson et al, 2012). Pegylated liposomal doxorubicin (PLD) with BORT is FDA-approved for the treatment of MM pts who have received one prior therapy not containing BORT. The combination of PLD and LEN or thalidomide has shown efficacy for both RR and frontline MM pts (Offidani et al, 2006; 2007). We have also demonstrated that both the efficacy and tolerability of LEN in combination with DEX, PLD and BORT (DVD-R) may be improved by changing the doses and schedules of these drugs (Berenson et al, 2012). Based on these results, we hypothesized that the combination of POM, DEX and PLD would be effective for the treatment of RRMM pts. Thus, we conducted the first study investigating the safety and efficacy of POM in combination with intravenous (IV) DEX and PLD as a phase 1/2 trial using a modified dose, schedule and longer 28-day cycles for pts with RRMM. Methods The phase 1 portion enrolled MM pts w/ progressive disease whereas those enrolled in phase 2 also had to be refractory to LEN (single-agent or in combination), as demonstrated by progressive disease while receiving their last LEN-containing regimen or relapsed within 8 weeks of their last dose of this IMiD. Pts who have previously received POM treatment were ineligible. In the phase 1 portion, POM was administered at 2, 3 or 4 mg daily in three cohorts on days 1-21 of a 28-day cycle and DEX (40 mg) and PLD (5 mg/m2) were fixed and given intravenously on days 1, 4, 8, and 11. Results As of June 20th, 2014, 48 pts were enrolled in the trial and a total of 47 pts had received study drug. Pts had received a median of 4 prior treatments (range 1-18), with a median of 2 prior IMiD-containing regimens (range, 0-8). Fifty-three percent of the pts had received a prior PLD-containing regimen and 21% had received a prior IMiD and PLD combination treatment. Among all enrolled pts, 40 pts discontinued treatment and seven remain active. Pts completed a median of 3 cycles (range: 1-8), with a median follow-up time of 5.4 months (range: 0-22). During the phase 1 portion of the trial, the maximum tolerated dose (MTD) of POM was established at 4 mg. Enrollment of pts into the phase 2 portion of the trial began at the MTD. However, neutropenia ≥ grade 3 was observed at this dose in 10/17 (58.8%) phase 2 pts; and, as a result, the protocol was amended so that the MTD was lowered to 3 mg for all pts subsequently enrolled. Among the 36 pts enrolled in phase 2, 78% percent were refractory to LEN and steroids with or without other agents and 47% had previously received PLD. A median of 2 cycles (range, 1 to 8) were administered among the pts enrolled in phase 2. Thirty-five pts were evaluable for response as one pt was active but had not yet had any post-baseline disease assessments. Among all pts enrolled in phase 2, the overall response rate (ORR) and clinical benefit rate (CBR) were 29% and 49%, respectively, with 6 pts (17%) showing stable disease and 12 pts (34%) demonstrating progressive disease. For all pts enrolled in phase 2, the median follow-up time was 4.7 months (range 0-12) and the median PFS was 5.3 months. ORR and CBR for pts in the phase 2 were higher among pts receiving POM at 3 mg (32% and 58%, respectively) than among pts receiving POM at 4 mg (25% and 37%, respectively). Pts receiving the 4 mg dose of POM experienced more toxicities resulting in discontinuations, which likely explains the lower ORR and CBR observed among pts receiving this POM dose. Common ≥ grade 3 adverse events observed throughout the trial were neutropenia (21 pts; 44.7%), lymphopenia (10 pts; 21.3%), and hyponatremia (4 pts; 8.5%). One pt died of grade 5 sepsis. Conclusions This phase 1/2 trial is the first evaluating POM with PLD and DEX and demonstrates that the combination of POM at 3 mg, PLD and DEX using a modified 28-day cycle schedule is safe and effective for the treatment of MM pts refractory to LEN.

e16210 Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with a 5-year survival rate of 10%. Overexpression of c-Met is associated with the poor prognosis in patients with PDAC and it was noted that phosphorylation of c-Met is increased in gemcitabine-resistant PDAC. AL2846 is an oral c-Met inhibitor, which targets multiple receptor tyrosine kinases (RTK’s) primarily including c-Met, VEGFR1, KIT, Axl and RET. The combination of AL2846 with chemotherapy may improve the clinical efficacy of PDAC. Based on these consideration, a phase Ⅰ clinical trial was initiated to determine the maximum tolerated dose (MTD) of AL2846 in combination with gemcitabine in patients with advanced PDAC and to clarify the potential anti-tumor activity. Methods: Patients with untreated locally advanced or metastatic PDAC were enrolled to receive oral AL2846 once daily in a fasted state in combination with gemcitabine intravenous infusion over 30 min on days 1, 8, and 15 every 28 days. The starting dose level is AL2846 40 mg and gemcitabine 1000 mg/m2. Primary endpoint was the maximum tolerated dose (MTD), defined as the highest dose level at which ≤33 % of patients incurred a dose-limiting toxicity (DLT), and RP2D. Secondary endpoints included response rate (ORR), progression-free survival (PFS) and overall survival (OS). Results: As of January 1, 2021, a total of 15 patients with PDAC were enrolled and received 4 dose-levels of AL2846 (40 mg: n = 1; 60 mg: n = 6; 90 mg: n = 3; 120 mg: n = 5) treatment. DLTs occurred in 1 patient who experienced grade 3 abnormal liver function. The most common grade 3 or above drug-related adverse events were neutropenia (n = 7, 46.7%), thrombocytopenia (n = 5, 33.3%), leukopenia (n = 4, 26.7%), GGT increased (n = 4, 26.7%), hyperbilirubinemia (n = 3, 20.0%) and alkaline phosphatase increased (n = 3, 20.0%). Among the 15 patients available for efficacy evaluation, 1 patient (6.6%) achieved partial response who was at the dose levels of 90mg. There were 4 patients whose PFS was more than 5 months. Although there were no more than 2 DLT events, we chose 90 and 120 mg as the target dose for RP2D according to the dose reduction and proportion of gemcitabine. Conclusions: The RP2D of AL2846 in combination with standard dose of gemcitabine were 90 and 120 mg QD continuously. The results demonstrated that AL2846 in combination with gemcitabine was well tolerated at doses up to 120 mg. Further clinical studies about the efficacy of AL2846 in pancreatic cancer are in progress. Clinical trial information: CTR20201021.

Abstract Background Glioblastoma (GBM) is the most common malignant brain tumour in adults with a median survival from progression of 8 months. A recent phase 1 study of temozolomide (TMZ) and 1:1 CBD:THC (Sativex) offers evidence of efficacy in patients with recurrent GBM (NCT01812603). Methods All patients receiving TMZ & Sativex (75mg/m2 daily d1 – 21 q28; Sativex continuously) for relapsed GBM or grade 3 astrocytoma at our centre were identified. Patient, tumor and treatment characteristics were recorded, and response based on sequential MRI scans using modified RANO criteria assessed. Results 13 patients were treated over 18 months. The median age was 56; 69% were male. All had received initial chemo-radiotherapy (12 patients: 60 or 59.4Gy/30–33#; 1 patient: 45Gy/15#). 6 patients underwent reresection at recurrence. 4 patients were treated at first progression, 7 at second progression, and 2 at third or later progression. The median number of cycles of TMZ and sativex was 2. The combination treatment was tolerated well by all patients treated, with no Grade 3 or 4 toxicities, the only complaints being of discomfort in mouth after spray and ‘spaced out feeling’. Patients stopped treatment due to evidence of progressive disease on sequential MRI sign or physical deterioration. Median Overall Survival (OS) from initiation was 5.9 months (177 days); Progression Free Surival (PFS) at 3 months was 50%. Conclusion These results highlight some discrepancies in OS in comparison to the previous trial (NCT01812603), but our patients were treated at second/ third recurrence. We agree that the combination is well tolerated.

PURPOSE The Children's Cancer Group conducted a phase I trial of temozolomide stratified by prior craniospinal irradiation (CSI). PATIENTS AND METHODS Children and adolescents with recurrent or progressive cancer were enrolled. Temozolomide was administered orally daily for 5 days, with subsequent courses administered every 21 to 28 days after full hematologic recovery. Dose levels tested included 100, 150, 180, 215, 245, and 260 mg/m2 daily. RESULTS Twenty-seven patients on the non-CSI stratum were assessable for hematologic toxicity. During the first three dose levels (100, 150, and 180 mg/m2 daily), only grades 1 and 2 hematologic toxicity occurred. One patient at 215 mg/m2 daily had grade 3 hematologic toxicity. Three of eight patients (38%) treated at 245 to 260 mg/m2 daily had dose-limiting toxicity (DLT), which included both neutropenia and thrombocytopenia. Twenty-two patients on the CSI stratum were assessable for hematologic toxicity. Hematologic DLT occurred in one of six patients (17%) at 100 mg/m2 daily and in two of four patients (50%) at 215 mg/m2 daily. No nonhematologic DLT occurred; nausea and vomiting occurred in more than half of the patients. After two courses of temozolomide, 10 patients had stable disease (SD), and three patients had a partial response (PR), one of whom subsequently had a complete response (CR) that persists through 24 months of follow-up. CONCLUSION The maximum-tolerated dose (MTD) of temozolomide for children and adolescents without prior CSI is 215 mg/m2 daily and for those with prior CSI is 180 mg/m2 daily for 5 days, with subsequent courses that begin on day 28. Temozolomide is well tolerated and should undergo phase II testing in children and adolescents.

Abstract Background: Multiple myeloma (MM) is an incurable disease with a anticipated overall survival (OS) ranging from months to decades. Modest improvements in OS have been made with high-dose chemotherapy with peripheral blood stem cell transplant (PBSCT), but to date prognostic factors have a greater impact on OS than do individual therapies. Patients with adverse risk factors such as elevated beta-2 microglobulin (B2M), plasma cell labeling index, deletions of the long arm of chromosome 13 by metaphase cytogenetics (del 13q) require innovative new treatment strategies. Bortezomib has significant activity in patients with both newly diagnosed and relapsed/refractory MM, but its specific role in patients with adverse features has not yet been defined. Methods: Patients with newly diagnosed “high-risk” myeloma (B2M ≥ 5.5., PCLI ≥ 1, or del 13q) and adequate organ and functional status were eligible. Patients were treated with bortezomib 1.3 mg/m2 day 1, 4, 8, and 11 every 21 days for 8 cycles as induction. After induction, patients were scheduled to receive bortezomib 1.3 mg/m2 every other week indefinitely. Elective peripheral stem cell mobilization (growth factor alone) was allowed after 4 cycles of bortezomib. Patients relapsing on maintenance schedule were to have the full induction schedule resumed. Responses were by the EBMT criteria but a very good partial response category was included. The primary end-point was the response rate in these high-risk patients (90% power to detect a response rate of 50% or higher). The study decision rule requires that 16 or more responses, among 39 eligible patients, are seen in order to declare this treatment effective. Results: Between March 15, 2004 and March 10, 2005, 44 patients enrolled on study. Among the 43 eligible patients, median age was 63; 51% were male. All patients had high risk disease: del 13q (6/41); plasma cell labeling index ≥1% (16/34); and B2M≥5.5 (34/43). Preliminary response data are available for 18 of the 44 cases enrolled, of which 7 had partial response, 1 had minimal response, 1 had no response, 2 had progressive disease, and 5 were unevaluable. Among those patients completing induction therapy and with response information, the median number of cycles of therapy administered is 5, range (0,8). The most common non-hematologic adverse events (AEs) of grade 3 or higher included hyponatremia (9 patients) and diarrhea (6 patients). Mild sensory peripheral neuropathy was common: grade 1, 16 patients; grade 2, 2 patients. Only 1 patient had grade 3 peripheral neuropathy. One patient died after receiving 2 doses bortezomib due to heart block and asystole. Two patients had a grade 4, 25 patients had grade 3, and 13 had grade 1 or 2 as the worst grade non-hematologic adverse event. Based on data received by August 1, 2005, 18 patients have gone off study: AEs (2); death (1); progressive disease (9); and other reasons (6). Updated results on the full study population along with FISH data for IgH translocations and deletions of 13q and 17p will be presented at the meeting. Conclusions: Preliminary results suggest that upfront bortezomib has activity in patients with high-risk MM, but further follow-up is required.

Abstract HCD122 is a novel, fully human, IgG1 antagonistic monoclonal antibody targeting the CD40 receptor. This antibody blocks CD40-mediated signaling and is a potent mediator of antibody-dependent cellular cytotoxicity (ADCC). Previous preclinical investigation confirmed expression of CD40 on myeloma cells in the majority of patients and reported antitumor activity of HCD122 against multiple myeloma cells ex vivo (Tai, Y et al. Cancer Res2005; 65(13): 5898–5906). This ongoing phase 1 study will determine the maximum tolerated dose of CHIR-12.12 in multiple myeloma patients (pts) who are relapsed or refractory after at least one prior therapy. Planned dose levels are 1, 3 and 10 mg/kg administered IV once weekly for 4 weeks. Each dose group will enroll 3–6 pts to evaluate safety, pharmacokinetics (PK) and clinical response. To date, 9 pts have been treated at 2 dose levels: 3 pts at 1 mg/kg and 6 pts at 3 mg/kg. Median patient age is 65 yrs (46–81 yrs); median number of prior therapies is 3 (2–12). No dose limiting toxicity (DLT) occurred at the 1mg/kg dose level. At 3 mg/kg, 1 DLT of grade 4 thrombocytopenia occurred in 1 pt. No other grade 3 and 4 lab abnormalities and adverse events have been reported. In 7 pts with available data, infusions were well tolerated, with easily managed grade 1–2 toxicities, primarily chills (5 pts), nausea (3 pts), pyrexia (2 pts), and arthralgia (2 pts) mainly reported during the first infusion. Preliminary PK analysis showed more than dose proportional - increase in Cmax and AUC at the 3 mg/kg dose level compared to the 1 mg/kg dose level. At the 3 mg/kg dose, antibody accumulation occurred week-to-week; the mean Cmax after the fourth infusion on Day 22 was 126.1 mg/mL(range 52 – 195 ug/mL) and HCD122 levels were measurable up to Day 57 and in one patient up to Day 99. One week after the last 3 mg/kg dose, trough levels ranged from 28 to 109 mg/mL. Of the 3 pts at 1 mg/kg, one showed stable disease (SD) for >23 weeks and two had progressive disease (PD) by week 5. Of the 6 pts at 3 mg/kg, one had partial response (PR) at week 9 and was confirmed at week 15, one had SD for > 5 weeks, and 4 had PD at week 5. One pt with PD terminated the study before final safety evaluation, and must be replaced before assessment of the 3mg/kg dose level is complete. Thus, in preliminary studies, HCD122 appears to be safe and well tolerated to date at doses of 1 mg/kg and 3 mg/kg weekly for 4 doses and shows promising anti-myeloma activity. Enrollment is continuing to determine MTD.
