7539 Background: Interferons (IFNs), which can offset the Th2 dominance associated with PCL have been successfully used to treat these PCL. Intratumoral (i.t.) injection of TG1042 (a non-replicating recombinant adenovirus with a human IFNγ cDNA insert) induces high local production of IFNγ without severe toxicity associated with systemic delivery. Methods: We undertook a phase I/II multicentric trial of repeated, i.t. injections of TG1042 in patients with advanced primary T cell (CTCL) or B cell (CBCL) CL. One to 3 lesions were injected on day 1, 8, and 15 (a 4-week cycle) and thereafter up to 12 cycles. Immunohistochemistry and quantitative PCR were performed on injected lesions biopsied at baseline and after the 1st cycle. In the phase I, 18 patients were enrolled in 3 successive cohorts at the doses of 3 × 109 viral particles (vp) (n = 3), 3 × 1010 vp (n = 3) and 3 × 1011 vp (n = 12). In the phase II, 18 evaluable patients were planned to be treated at 3 × 1011 vp. Results: To date, enrollment is complete, 39 patients (32 CTCL and 7 CBCL) have been included, 9 of them are still on treatment. Patients received a median of 4 lines of prior therapy. 11 patients were at stage Ib and 16 patients at higher stage. Altogether, 245 injections of TG1042 have been administered. Treatment was well tolerated with 8 grade 3 related adverse events. Injection site reaction and flu like syndrome are the most common adverse events. Histology demonstrates pronounced changes in infiltrate patterns with signs of vasculitis, increased numbers of eosinophils, neutrophils, CD8 and TIA-1+ve cells. CD4/CD8 ratio decreased in most tumors. Transgene-IFNγ mRNA was detected in injected lesions. Gene expression analysis of biopsies and PBMC shows up-regulation of IFNγ genes. Local clinical response has been observed in 17 (including 9 complete responses [CR]) out of 31 evaluable patients. 13 global responses (7 CR) out of 30 evaluable patients have been observed. All 5 evaluable CBCL responded (3 CR). Conclusions: These results demonstrate that TG1042 is well tolerated and presents a potential significant benefit for the treatment of both CTCL and CBCL. A phase II is planned in patients with CBCL to confirm those encouraging results. [Table: see text]

Abstract PCL has been successfully treated with interferons (IFNs), which can offset the Th2 dominance associated with PCL. Intratumoral (IT) injection of TG1042 (a non-replicating recombinant adenovirus with a human IFN-γ cDNA insert) allows high local levels of IFN-γ without severe toxicity induced by systemic delivery. We undertook a multicentric, phase I/II, open-label, trial of repeated, IT injection of TG1042 in patients with advanced primary T cell (CTCL) and multilesional B cell (CBCL) cutaneous lymphoma. The designated lesions were injected on day 1, 8 and 15 with no injection in the fourth week (1 cycle) and thereafter up to 4 cycles. Immunohistochemistry and qPCR were performed on injected lesions biopsied at baseline and after each cycle. In the phase I step, undertaken on a monocentric basis, 9 patients were enrolled in 3 successive cohorts at the doses of 3×109 viral particles (vp), 3×1010 and 3×1011 vp injected in only one lesion and 9 additonal patients were treated at the doses of 3×1011 vp divided in up to 3 lesions. In the phase II step, 18 additional patients have been planned to be treated on a multicentric basis at 3×1011 vp injected in up to 3 lesions. To date, the 36 planned patients (30 CTCL and 6 CBCL) have been enrolled and received a total of 280 injections, 26 patients have completed the treatment. Treatment is well tolerated with only 3 grade III toxicity. Injection site reaction and flue like syndrom are the most commonly observed adverse events. Local clinical response has been observed in 13 (7 complete responses) out of 27 evaluable patients. Disappearance of non-injected lesions was also observed and led to 12 overall responses (6 complete responses) out of 26 evaluable patients. Histology demonstrates pronounced differences in infiltrate patterns following treatment, with signs of vasculitis and increased numbers of eosinophils, neutrophils, CD8 and TIA-1+ve cells. CD4/CD8 ratio decreased in most tumors. Transgene-IFN-γ mRNA was detectable in injected lesions. Gene expression analysis of biopsies and PBMC shows up-regulation of IFN-γ and various immune response-associated genes. Final clinical and immunological data will be presented. In conclusion, these data show that the administration of TG1042 is well tolerated and results in clinical responses associated with in situ immunological changes. These encouraging results demonstrate a potential significant benefit of TG1042 for the treatment of primary cutaneous lymphoma.

Abstract Background: Thalidomide has marked activity in both untreated and heavily pretreated myeloma. Its activity in part is believed to be due to inhibition of bFGF and VEGF induced angiogenesis. Elevated levels of bFGF in serum and urine have correlated with decreased survival in lymphoma possibly through up-regulation of BCL-2. Methods: 25 patients (pts) with previously treated F-NHL and SLL were registered and treated on this multi-institutional study from July 2001–April 2004 to evaluate the efficacy and safety of oral thalidomide in this patient group. Pts had B-cell SLL (7: 36.8%), F-NHL grade 1 (7: 36.8%), grade 2 (3: 15.8%) and grade 3 (2: 10.1%) NHL. Pts were eligible for entry with up to 3 prior chemotherapy (CT) and 2 immunotherapy (IT) regimens provided performance status was ≥ 1. Pts with new onset of B-symptoms, rising LDH, rapid tumor growth or greater than one year from initial diagnosis were required to undergo repeat lymph node biopsy to exclude recent transformation. Pts with CNS involvement, prior peripheral neuropathy >gr 1, HIV+, and pregnant or nursing women were also excluded. Pts were required to have Cr <2 x ULN, AST/ALT <2.5 x ULN and an ANC > 750. Median age at study entry was 60 years (36–87). Prior therapy was evaluated in 20 pts and 17/20 had received multi-agent CT while 12/20 pts received prior IT. Thalidomide was initiated at a dose of 200 mg daily and escalated by 100 mg daily every 1–2 weeks as tolerated with a maximal dose of 800 mg/d. If ≥ gr 2 peripheral neuropathy or ≥ gr 3 somnolence or mood changes occurred, the dose was held for one week and restarted at 50% of the prior daily dosage. Results: The median daily dose was 400 mg (range 50–800 mg). There was 1 complete response (CRu-residual abnormality) in a pt with SLL and one partial response in a pt with F-NHL grade 1 (ORR 8%: 95%CI: 1–26%). 16 pts had progressive disease during therapy and 2 died of disease soon after stopping therapy due to adverse events. One patient continues on therapy without progression of disease to date. The remaining 4 pts were taken off of therapy prior to the first 3 month evaluation. The reason for withdrawal was pt refusal (2) and adverse events (2). The median event free survival was 2.6 months (95% CI:1.4–4.4 mos) with a median overall survival of 23.3 months. Toxicity information on 24/25 pts revealed 4 (17%) with grade 4 neutropenia with 1/4 febrile as well. The most common grade 3 toxicities were anemia (13%), dyspnea (13%), fatigue (8%) and neurologic toxicities consisting of somnolence, dizziness, depression and anxiety (21%). Peripheral sensory neuropathy was reported as gr 2 in 8% and gr 3 in 8%. However, 38% of pts were reported as experiencing gr 2 fatigue. There were no grade 5 toxicities. Conclusion: These phase II trial results in a pretreated pt population demonstrate that, despite an acceptable toxicity profile, thalidomide has only minimal efficacy in F- NHL and SLL.

Abstract Abstract 3009FN2 Objective: To determine toxicity and efficacy of adding fludarabine (FLU) to a regimen of total body irradiation (TBI), anti-thymocyte globulin (ATG) and cyclophosphamide (CY), with de-escalation of the CY dose. The goal is to minimize CY-related toxicities while preserving (or improving) engraftment and survival in patients with SAA receiving an unrelated donor marrow transplant. Patients and Methods: Since May 2006, the Blood and Marrow Transplant Clinical Trials Network (BMT CTN), sponsored by the NHLBI and NCI, has conducted a prospective Phase I/II clinical trial of unrelated donor marrow transplantation in SAA (BMT CTN 0301). Patients with SAA are eligible if they are < 65 years, have adequate organ function, and have an available unrelated marrow donor matched 7 of 8 HLA-A, B, C, DRB1 loci. Patients with Fanconi anemia and other marrow failure syndromes are excluded. All patients receive TBI 200 cGy, ATG (either thymoglobulin: 3 mg/kg IV or ATGAM 30 mg/kg IV daily × 3, days –4 to –2), FLU (30 mg/m2 IV daily × 4, days –5 to –2). The Phase I portion of the trial sequentially tested four CY dose levels: 150 mg/kg (administered days –4 to –2); 100 mg/kg (days –3 to –2); 50 mg/kg (day –2); and, 0 mg/kg, and allowed enrollment of up to six patients at each CY dose level unless toxicity or graft failure boundaries were crossed. In the Phase II portion of the trial, patients enroll onto the optimal CY dose level, which is chosen using adaptive Bayesian criteria to rank desirability of the CY doses. All patients are followed for two years after transplantation. Early stopping guidelines are used to monitor for graft failure and early transplant-related mortality through day 100. Results: Twenty-one patients accrued to the Phase I portion of the trial. CY dose level 0 mg/kg was closed after all three enrolled patients developed secondary graft failure. All received a second allograft. One patient remains alive at 23 months after the first transplantation. The other two died from adult respiratory distress syndrome (ARDS) at 114 days after the first transplant and idiopathic pneumonia at 200 days after the first transplant. Review of Phase I results for the other three dose levels suggested CY dose 150 mg/kg as the optimal dose level for Phase II testing. However, after an additional eight patients were treated at this dose, the level was closed to further accrual because of excess toxicity. Seven of the 14 patients receiving 150 mg/kg of CY (and 7 of the last 8 enrolled) died. Causes of death were cardiac/pulmonary/multi-organ failure (n=4), ARDS (n=2), and parainfluenza virus type 3 pneumonia (n=1). Bayesian evaluation of the two remaining dose levels indicates very similar desirability scores and accrual continues at both the CY 100 mg/kg and 50 mg/kg levels. As of July 15, 2011, a total of 61 patients have been enrolled, 17 on the two closed levels, 33 on the 100 mg/kg level and 11 on the 50 mg/kg level. Conclusions: Early analysis of this trial, made necessary by these unexpected severe adverse events, revealed two important findings among patients receiving low-dose TBI, ATG, and FLU at the doses outlined: 1) CY dose 0 mg/kg is associated with higher than expected graft failure; and, 2) CY dose 150 mg/kg is associated with excess transplant-related toxicity. Neither CY dose level should be tested further in the context of the regimen used in this trial. To date, the two intermediate CY dose levels (100 mg/kg and 50 mg/kg) have not crossed the graft failure or fatality stopping boundaries and accrual is in progress.

Early Phase Clinical Trials

6576 Background: Arguments have been made against early phase clinical trials (CTs) as possibly being unethical because its risk may outweigh its potential benefits. Whether this is true in the light of newer biological treatment for cancer is unknown. We therefore examined the association between the incidence of serious adverse events according to type and sponsorship of CTs in pts with lymphoma. Methods: All IRB approved CTs at the University of Nebraska Medical Center from Jan 2000-June 2005 classified as therapeutic for lymphoma involving a biological agent were included. CTs were classified in two ways: by type of CTs (phase I vs II vs III) and sponsorship (Investigator-initiated vs Industry-initiated. Multivariate logistic regression was used to evaluate the association between types/sponsorship of CTs with the incidence of IRB serious adverse events (SAE; no vs yes) and fatal adverse events (FAE; no vs yes) while adjusting for age, sex, race, lymphoma type and stage, interval from dx to tx, co-morbid conditions, and previous tx. Results: 357 pts with lymphoma enrolled in 29 CTs were included. The median age of pt was 54y (21–88). 41% of the pts had follicular lymphoma, 36% diffuse large cell, 14% mantle cell and 9% were other types. 59% had Stage IV lymphoma. 71% of the pts participated in investigator-initiated CTs, while 29% participated in industry-initiated CTs. 21% of pts were enrolled in phase I, 65% in phase II and 14% in phase III studies. SAEs were seen in 49 pts (14%), while FAEs occurred in 13 pts (4%). Multivariate analysis showed the risk of having SAE was independent of the type or sponsor of CTs. Additionally, the risk of FAEs was not associated with the type of CTs. However, the risk of having FAEs was less in investigator- iniatiated CTs than in industry-iniatiated trials (Odds Ratio: 0.13 (95% CI, 0.03–0.61, p = 0.01). Conclusions: Our study showed that in CTs involving biological treatments, the incidence of SAEs was not associated with the type or sponsor of CTs suggesting that use of biological agents in phase I studies may have similar risks to phase II/III trials. Further studies should be done in other types of malignancies to evaluate further the decrease frequency of FAEs seen in investigator-initiated trials.

6570 Background: Inhibition of vascular endothelial growth factor receptors (VEGFR) can block growth and trigger apoptosis in neoplastic cells. AZD2171 (cediranib) is a highly potent, orally bioavailable, VEGFR-1/2 inhibitor. We conducted a phase II study of the efficacy of AZD2171 for the treatment of MDS. Methods: Adults with MDS (IPSS Int-2 or High) were eligible if they exhibited adequate organ function and ECOG 0-2. The primary endpoint was proportion of responses according to the IWG criteria assessed at one and every 3 months. Prior investigation of cediranib at 45 mg daily in patients with acute leukemia demonstrated toxicity concerns and therefore, the starting dose of this study was lowered to 30 mg daily. Results: A total of 16 pts with MDS (median age 73 years) were enrolled at a 30 mg starting dose, and all were evaluable. Median baseline marrow blasts were 12.0 % (range 2-18); 3 pts (18.8 %) had low, 6 (37.5 %) intermediate, and 7 (43.8 %) had high risk cytogenetics. Prior therapy included azacitidine (n=7), decitabine (n=2), cytarabine (n=2), erythropoietin-stimulating agents (ESAs) (n=2), lenalidomide (n=1), or none (n=6). Patients were treated for a median of two 28-day cycles (range 1 to 11). There were no confirmed responses. Patients with baseline blasts > 5% showed no significant reduction in the blast count at 4 and 12 weeks. Median OS was 4.7 mo (95% CI: 2.6 – 11.6). Median TTP was 3.8 mo (95% CI: 1.7 – 10.8). Grade 4 hematological adverse events at least possibly related to cediranib were neutropenia (n=2) and thrombocytopenia (n=4). Grade 3 hematological adverse events at least possibly related to study treatment included: neutropenia (n=3), thrombocytopenia (n=2), and anemia (n=2). Grade 3 non-hematological adverse events included fatigue (n=4), dyspnea (n=3), dehydration (n=2), diarrhea (n=2), nausea (n=2), asthenia (n=1), and hypertension (n=1). Hypertension and proteinuria was uncommon with the 30 mg/day dose. Conclusions: With no confirmed response from 16 patients, cediranib was determined to be ineffective at a dose of 30 mg daily in our patient population.

Dose Limiting Toxicity

643 Background: Capecitabine is an oral fluoropyrimidine prodrug, which is converted to fluorouracil (5-FU) predominantly in the tumor cells. In Japan, capecitabine is mainly used in combination with oxaliplatin (XELOX) in treatment for metastatic colorectal cancer (mCRC) since its approval in 2009. The results of capecitabine plus Irinotecan (CPT) (XELIRI) with or without bevacizumab (BV) in EU or US patients were previously reported, but not in Japanese. Thus, we conducted this study to assess the safety and efficacy of XELIRI plus BV in Japanese patients with mCRC. Methods: Patients with prior chemotherapy including oxaliplatin and BV for mCRC, wild or hetero type of UGT1A1 *6*28 were eligible for this study. This was a phase I study composed of two steps, and dose limiting toxicity (DLT) was assessed during the first treatment cycle. Treatment comprised capecitabine 1,000 mg/m2 twice daily from the evening of day 1 to the morning of day 8, intravenous CPT 180 mg/m2 on day 1, and BV 5mg/kg on day 1 every two weeks. To evaluate the initial safety, 3-6 patients received XELIRI+BV (CPT 150mg/m2) in step 1, and 6 patients received XELIRI+BV (CPT 180mg/m2) in step 2. If DLT occurred in 1 patient in step1, 3 patients would be newly added to step 1, and if in none of 3 or 1-2 of 6 patients, the step 2 would be started. If DLT occurred in less than or equal to 2 of 6 patients in step 2, phase II study would be proceeded, and if In more than 2 of 6 patients, phase II would be conducted at the recommended dose of step 1. Results: In step 1 and 2 of phase I, initial safety of 9 patients was confirmed without occurrence of DLT. Adverse events observed in step 1 and 2 were: neutropenia in 2 and 1; anorexia in 1 and 1; diarrhea in 1 and 1; stomatitis in 1 and 1; alanine or aspartate aminotransferase increased in 1 and 3, respectively. There was no grade 3 or greater adverse events. Conclusions: In mCRC patients with wild or hetero of UGT1A1*6*28 genotype, safety of biweekly XELIRI+BV was confirmed and recommended dose of CPT-11 was determined as 180mg/m2. Interim analysis of safety of phase II part will be reported at the meeting.

e19147 Background: Despite advances in targeted therapies, there is an ongoing need to develop new and effective cytotoxic drug combinations in NSCLC. Preclinical evaluation has demonstrated additive cytotoxicity of pemetrexed and taxanes. We evaluated the safety and efficacy of combining nab-paclitaxel (nP) and pemetrexed (P) in solid tumors with a focus on NSCLC for the phase II expansion. Methods: A 3+3 dose-escalation design was used to determine the maximum tolerated dose (MTD) and the recommended phase II dose (RP2D). Three dose levels were tested: P 500 mg/m2 day 1 plus nP on day 1 at doses of 180, 220, and 260 mg/m2 every 21 days. Dose limiting toxicity (DLT) in cycle 1 was defined as: grade 4 platelets or grade 3 platelets with bleeding, neutropenia with fever or documented infection, or other grade ≥ 3 non-heme toxicity. Phase II eligibility included advanced NSCLC, ≤ 2 line prior therapy, PS 0-1, adequate organ function. Primary endpoint for further study was response rate (RR) ≥ 25%. Results: Planned dose escalation during the Phase I portion was completed without reaching the MTD. The RP2D was P 500 mg/m2 and nP 260 mg/m2. The phase II portion accrued 37 pts before early closure due to increasing use of first-line pemetrexed/platinum doublet therapy in non-squamous NSCLC. Phase II patient characteristics: median 63 (45-77); M:F 23:14; median cycles 3. In 31 assessable patients: 5 PR, 12 SD and 14 PD. Efficacy: RR =14%; disease control rate (DCR) = 46%; median survival time (MST) = 8.7 months. Pts in the DCR group had a MST of 15.4 vs 4 months in the PD group (p=0.02). Conclusions: P 500 mg/m2 day 1 with nP 260 mg/m2 was feasible and well tolerated. The phase II component demonstrated activity in second-line therapy of advanced NSCLC. Practice patterns have evolved; so further trials of this regimen are not planned. Clinical trial information: NCT00470548.

619 Background: Neuroendocrine tumors (NETs) are relatively rare and heterogeneous tumors arising throughout the aerodigestive tract, which are incurable and life-limiting when metastatic. Prior studies of checkpoint inhibitors in NET patients have yielded minimal evidence of efficacy. Historically, effective therapies for advanced, progressive NET yield response rates less than 10% and progression-free survival (PFS) durations of approximately 11 months, as compared to approximately 4.5 months with placebo. Methods: We undertook a phase II basket study of atezolizumab in combination with bevacizumab in patients with rare cancers, and present here the data from the pancreatic NET (pNET) cohort and extrapancreatic NET (epNET) cohort, each of which included 20 patients with grade 1-2 NET that was progressive under any prior therapy. Patients received 1200mg of atezolizumab and 15mg/kg of bevacizumab IV q 21 days. The primary endpoint was confirmed objective response by RECIST 1.1. Results: The confirmed objective response rate with this combination was 20% (95% CI 6-44%) in the pNET cohort and 15% (95% CI 3-38%) in the epNET cohort. The median PFS in the pNET cohort is 19.6 months (95% CI 10.6-NR), while it was 14.9 months (95% CI 6.1-NR) in the epNET cohort, 1-year PFS was 75% and 52%, respectively. The combination was well-tolerated in this patient population, with the most common related treatment-emergent adverse events being hypertension (47.5%), proteinuria (37.5%), and fatigue (35%). The most common related grade 3/4 adverse events were hypertension (20%) and proteinuria (7.5%). Conclusions: The combination of atezolizumab and bevacizumab demonstrated moderate clinical activity in patients with advanced NETs. As pre-treatment and on-treatment biopsies were obtained for all patients, correlations with immune infiltration, mutations, and transcriptome alterations should provide additional insight into the mechanisms of response and resistance. Clinical trial information: NCT03074513.

17064 Background: PR-350 was a nitoroimidazole derivative as a hypoxic cell radiosensitizer with low toxixity, developed by POLA Chemical Industries Inc.(Yokohama, Japan). We undertook this phase I/II trial to characterize the safety, pharmacokinetics (PK), and antitumor activity of the combination chemotherapy of platinum agent and paclitaxel followed by PR-350 and concurrent TRT in pts with LANSCLC. This trial was conducted by West Japan Thoracic Oncology Group (WJTOG). Methods: Major eligibility included 20–74 years old, histologically or cytologically proven NSCLC, surgically unresectable stage IIIA and IIIB, no prior therapy, ECOG performance status of 0 to 1, and adequate organ functions. All pts received two cycles of cisplatin of 80 mg/m2 and paclitaxel of 180 mg/m2 before radiotherapy with PR-350. The radiation dose was 60 Gy in 30 fractions of 2 Gy over 6 weeks. PR-350 dose of 2000 mg/m2 was administered as a 25 minutes intravenously prior to irradiation daily. The starting consecutive days were 10 times with daily TRT, and the times were escalated in increments of 10 times for successive groups of 6 new pts. PK studies of PR-350 were performed on the first day and the end. Induction chemotherapy of carboplatin (AUC = 6) and paclitaxel (200mg/m2) was also permitted in phase II portion. Results: 37 pts were enrolled into this trial. Major severe toxicity was radiation pneumonitis, which developed 2 treatment related deaths (TRD). Grade 3 or more esophagitis was not developed in this trial. PR-350 was able to administered 30 consecutive days with concurrent TRT. Overall response rate was 67.6% (95% CI: 50.2–82.0%). Median survival time was 16.8 months (95% CI: 12.1–21.9 months), and 1 and 2 year survival rate were 64% and 21%, respectively. No cumulative effect was demonstrated among 3 dose levels by PK studies. Conclusions: Induction chemotherapy followed by TRT with 30 times of PR-350 was well tolerated and promising for the treatment of LANSCLC.

Abstract ZD6474 targets angiogenesis by inhibiting VEGFR TK and also affects EGFR signaling by inhibiting EGFR TK activity. This oral agent showed dose-related tumor growth inhibition in a broad range of in vivo xenograft models. In Phase I studies, drug- and dose-related adverse events included rash, diarrhea, hypertension, and asymptomatic QT/QTc prolongation. Four patients with NSCLC included in the phase I studies exhibited partial responses. Because MM is a disease in which angiogenesis is postulated to be a relevant target for therapy, we conducted a phase II trial of ZD6474 100 mg p.o. daily in patients with MM who had relapsed following either high-dose chemotherapy and stem cell transplantation, or following non-high-dose chemotherapy. Although a higher dose was recommended for solid tumour trials, a dose of 100 mg p.o. daily produced plasma levels in phase I in excess of the IC50 for in vitro inhibition of VEGF-stimulated HUVEC proliferation and seemed well tolerated. For the study reported here, patients all had a measurable M protein in the serum or urine and were required to have an ECOG PS of 0, 1 or 2. Patients were excluded if they had any of: AGC <1.0x109/L or platelet count <50x109/L; bilirubin, AST and/or ALT >1.5xUNL; creatinine >2xUNL; K+ <4.0mmol/L; abnormal Ca2+ or Mg2+ levels, prior thalidomide treatment or pre-existing cardiac dysfunction. The primary efficacy endpoint was objective response as assessed by reduction in M protein. Following written, informed consent, 18 patients were entered into the study from five centers (9 male/9 female; mean age 64 yrs [35– 81]). Fourteen patients had relapsed following high-dose chemotherapy with stem cell transplant. One patient was ineligible due to elevated baseline calcium and one was not evaluable (off study due to non drug-related infection with < 14 days of therapy) . Patients were treated for 3.0– 29.4 weeks (mean 9.8 weeks). Overall, ZD6474 was well tolerated with only three patients missing doses of ZD6474. The most common drug-related adverse events were nausea, vomiting, fatigue, rash, pruritis, headache, diarrhea, dizziness, and sensory neuropathy, all of which were Grade I – II in severity. There were no drug-related serious adverse events. Laboratory adverse events were infrequent: one patient had Grade III anemia, and there were no Grade III changes in biochemistry. No significant QTc interval changes were seen. Fifteen patients had plasma samples obtained for at least 4 weeks after starting treatment. Trough levels of ZD6474 achieved or exceeded the IC50 for inhibition of VEGF-stimulated HUVEC proliferation in 13 of the 15 patients by day 28. There were no responses in M protein levels. In conclusion, ZD6474 was well tolerated at a dose of 100 mg per day and achieved plasma levels predicted to inhibit VEGF signaling. However, this was not reflected in clinical benefit since none of the patients had a reduction in M protein. ZD6474 development in solid tumors is continuing in a series of Phase II trials.
