8565 Background: Previous studies using low-dose (250 ug/dose) aerosolized sargramostim (granulocyte macrophage colony stimulating factor: aero-GM-CSF) for the treatment of metastatic melanoma, revealed anecdotal clinical responses that appeared to correlate with an increase in the number of tumor specific cytotoxic T lymphocytes (CTL) in blood. Herein, we address whether or not further dose escalation of aero-GM-CSF is safe, results in greater increase of melanoma specific CTLs, and affects clinical outcomes. Methods: A 5+5 dose escalation clinical trial was conducted to determine the dose of aero-GM-CSF that would increase in the frequency of peripheral blood melanoma specific CTLs in HLA-A2+ patients with metastatic melanoma to the lungs. Aero-GM-CSF was administered twice daily on days 1–7 and 15–21 of a 28 day cycle at doses of: 500, 750, 1,000, 1,250, 1,500, 1,750, and 2,000 ug per cohort. If at most 2 of 5 patients at a dose level reported a 5-fold increase in CTLs, dose escalation occurred. If not, 5 additional patients were treated at that dose. Dose escalation continued until =2 of 5 patients at a dose level developed severe toxicity, at least 7 of the 10 patients at a dose level reported a 5-fold increase in CTLs, or all dose levels were exhausted. Results: The study accrued 40 patients from August 2002 to July 2006. Four patients cancelled participation prior to treatment. One patient was replaced (500 ug) as he died within 13 days of registration. Among the 35 remaining patients, median age was 58 (23–84), 72% were male, and 72% had a PS=0. Dose escalation was not terminated due to toxicity. Toxicities = grade 3 (at least probably treatment related) included: grade 3 fatigue (1) at 1,000 ug; and grade 3 cough (1), and grade 4 dyspnea (1) at 1,750 ug. At the 2,000 ug dose, most patients (4 of 5) exhibited a greater than 2-fold increase in melanoma specific CTLs. Two of these patients remain on treatment: one with partial response at 14.0 months and the other with stable disease at 6.5 months. A 5-fold increase in tumor specific CTLs was not achieved in any patient. Conclusions: Aero-GM-CSF therapy administered at up to 2,000 ug/dose appears safe and seems to correlate with increased frequencies of tumor specific CTLs in a dose-dependent fashion. Further dose escalation followed by clinical efficacy testing is warranted. No significant financial relationships to disclose.

9549 Background: Preclinical findings have shown a synergy between RT and anti-CTLA-4 monoclonal antibody in several tumor animal models for both local tumor control and distant effects. Preliminary clinical data suggest that it could be due to an abscopal effect of RT. The Mel-Ipi-Rx phase 1 study aimed to determine the maximum tolerated dose (MTD) and safety profile of RT combined with ipilimumab in pts with metastatic melanoma. Methods: A 3+3 dose escalation design was used with 9, 15, 18 and 24 Gy dose of RT (in 3 fractions) at week 4 combined with 10 mg/kg ipilimumab (every 3 weeks for 4 doses). Pts with evidence of clinical benefit at week 12 were eligible for maintenance ipilimumab at 10 mg/kg every 12 weeks starting at week 24 until severe toxicity or disease progression based on immune-related response criteria (irRC). Results: 19 pts with advanced melanoma received ipilimumab between August 2011 and July 2015. Nine pts received the 4 doses of ipilimumab and 2 pts received maintenance ipilimumab (1 and 2 cycles respectively). All pts received the combined RT at week 4 in 3 fractions. All pts presented at least one AE of any grade. The most common AEs were asthenia, diarrhea, desease-related pain and fever. Grade 3 AEs occurred in 8 pts. They included colitis (n = 3), hepatitis (n = 2), anemia (n = 2), asthenia (n = 1), thyroid disorders (n = 1) and nausea/vomiting (n = 1). Nine pts discontinued the study owing to treatment-related adverse events including colitis (n = 6), hepatitis (n = 2) and DRESS (Drug Rash with Eosinophilia and systemic syndrome) (n = 1). DLT occurred in 2/6 pts in the cohort receiving 15 Gy. No drug-related death occurred. According to irRC, 4 partial responses (ORR: 21%) and 4 stable diseases were observed at week 24. The MTD was 9 Gy dose. One pt out of 12 treated in the 9 Gy cohort presented a DLT (grade 3 colitis). The median progression-free survival [95% CI] was 7.2 months [2.4 – 16.8]. The median overall survival [95% CI] was 14.4 months [7.2 – 20.4]. Conclusions: When combined with ipilimumab at 10 mg/kg, in the present design, the MTD of RT was 9 Gy. This combination appears to be associated with antitumor activity. Clinical trial information: 2010-020317-93.

PURPOSE The ability of growth factors to stimulate marrow recovery suggests their potential for use in dose intensification of cytotoxic drugs. We performed a phase I study of the alkylating agent thiotepa in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF), with the goal of dose-escalation of thiotepa. Thiotepa was selected based on its capacity for dose escalation to more than 1 g/m2 in the marrow transplantation setting. PATIENTS AND METHODS The starting dose of thiotepa (75 mg/m2) was the highest dose evaluated in our previous phase I trial. Thirteen patients received 22 courses of thiotepa and GM-CSF. The dose of GM-CSF was 10 micrograms/kg subcutaneously daily in six patients and 5 micrograms/kg in seven patients. RESULTS Three patients (23%) developed grade 3 to 4 neutropenia on the first course, with a recovery to more than 1000/mm3 in 4.7 days (mean). Recovery was as rapid with the 5 micrograms/kg as it was with the 10 micrograms/kg GM-CSF dose. Thrombocytopenia grade 3 to 4 affected seven of 13 (54%) patients in the first course; counts recovered to more than 50,000/mm3 in a median of 15 days. GM-CSF at either dose did not influence markedly the severity or duration of thrombocytopenia, and did not permit dose escalation of thiotepa. Among the seven patients who received a second cycle of treatment, six of seven experienced grade 3 or 4 thrombocytopenia that lasted a median of 15.5 days. Five had thrombocytopenia that lasted more than 35 days after one to three cycles of treatment. Plasma concentrations of thiotepa and tepa were measured by gas chromatography in eight patients. The plasma elimination of thiotepa fit a two-compartment open model with a harmonic mean terminal half-life of 2.44 hours. The mean total body clearance was 217.9 mL/min/m2, and the mean steady-state volume of distribution (Vdss) was 36.8 L/m2. The half-life of tepa was 7.98 hours, and the ratio of the area under the plasma concentration versus time curve (AUC) of tepa to that of thiotepa was 0.79. CONCLUSIONS These data were consistent with our previous observations at this dose, and indicated that the severity of toxicity in these patients was not explained by aberrant pharmacokinetic indices. We conclude that, independent of effects on neutropenia, severe and cumulative platelet toxicity precludes further escalation of thiotepa dose despite the use of GM-CSF.

PURPOSE To determine the toxicities and potential for dose escalation of intravenous (IV) bolus fluorouracil (5-FU) given with 500 mg/m2/d leucovorin (LCV) and granulocyte-macrophage colony-stimulating factor (GM-CSF). PATIENTS AND METHODS Thirty-seven patients received escalating doses of 5-FU/LCV on days 1 to 5 with subcutaneous GM-CSF either 5 or 10 micrograms/kg/d starting on day 6 or 3 micrograms/kg/d starting on day 1. 5-FU was escalated from 370 mg/m2/d by 15% increments between patient cohorts and within patients according to tolerance. RESULTS With GM-CSF starting on day 6, dose-limiting toxicity occurred during cycle no. 1 in all three patients entered at 5-FU 490 mg/m2/d. However, individual patients tolerated 5-FU doses up to 644 mg/m2/d. When all cycles were analyzed, grade 3 to 4 mucositis and grade 4 granulocytopenia complicated < or = 15% and < or = 6% of cycles with 5-FU doses < or = 560 mg/m2/d (115 cycles). With GM-CSF starting on day 1, dose-limiting granulocytopenia occurred during cycle no. 1 in five of 10 patients entered at 5-FU 490 mg/m2/d. Although the granulocyte nadirs were significantly lower at each 5-FU dose level with the concurrent GM-CSF schedule (eg, 490 mg/m2/d: median, 879/microL v3,286/microL; two-tailed P [P2] < .001), dose-limiting granulocytopenia complicated < or = 16% of cycles with 5-FU < or = 560 mg/m2/d (99 cycles); > or = grade 3 mucositis occurred in < or = 20% of cycles. Grade 3 to 4 diarrhea was unusual with either GM-CSF schedule. Most patients treated with GM-CSF > or = 5 micrograms/kg/d required dose reductions for constitutional toxicity; 3.0 to 3.8 micrograms/kg/d was better tolerated. Venous thrombosis occurred in 17% of patients (concurrent v sequential GM-CSF, 29% v 5%; P2 = .08). The median delivered 5-FU dose-intensity for GM-CSF starting either on day 6 or on day 1 was 615 and 647 mg/m2/wk (P2 = .41), respectively. Pharmacologic exposure to 5-FU increased with higher doses of 5-FU, and concurrent GM-CSF administration did not affect 5-FU clearance. CONCLUSION A starting dose of 425 mg/m2/d of 5-FU with LCV on days 1 to 5 could be safely combined with GM-CSF starting either on day 1 or day 6, with further 5-FU dose escalation according to individual tolerance.

AbstractEpigenetic therapies may modulate the tumor microenvironment. We evaluated the safety and optimal sequence of combination DNA methyltransferase inhibitor guadecitabine with a granulocyte macrophage-colony-stimulating-factor (GM-CSF) secreting colon cancer (CRC) vaccine (GVAX) using a primary endpoint of change in CD45RO + T cells. 18 patients with advanced CRC enrolled, 11 underwent paired biopsies and were evaluable for the primary endpoint. No significant increase in CD45RO + cells was noted. Grade 3–4 toxicities were expected and manageable. Guadecitabine + GVAX was tolerable but demonstrated no significant immunologic activity in CRC. We report a novel trial design to efficiently evaluate investigational therapies with a primary pharmacodynamic endpoint.Trial registry Clinicaltrials.gov: NCT01966289. Registered 21 October, 2013.

Purpose: Vaccination with irradiated, autologous melanoma cells engineered to secrete granulocyte-macrophage colony-stimulating factor (GM-CSF) by retroviral-mediated gene transfer generates potent antitumor immunity in patients with metastatic melanoma. Further clinical development of this immunization scheme requires simplification of vaccine manufacture. We conducted a phase I clinical trial testing the biologic activity of vaccination with irradiated, autologous melanoma cells engineered to secrete GM-CSF by adenoviral-mediated gene transfer.Patients and Methods: Excised metastases were processed to single cells, transduced with a replication-defective adenoviral vector encoding GM-CSF, irradiated, and cryopreserved. Individual vaccines were composed of 1 × 106, 4 × 106, or 1 × 107tumor cells, depending on overall yield, and were injected intradermally and subcutaneously at weekly and biweekly intervals.Results: Vaccines were successfully manufactured for 34 (97%) of 35 patients. The average GM-CSF secretion was 745 ng/106cells/24 hours. Toxicities were restricted to grade 1 to 2 local skin reactions. Eight patients were withdrawn early because of rapid disease progression. Vaccination elicited dense dendritic cell, macrophage, granulocyte, and lymphocyte infiltrates at injection sites in 19 of 26 assessable patients. Immunization stimulated the development of delayed-type hypersensitivity reactions to irradiated, dissociated, autologous, nontransduced tumor cells in 17 of 25 patients. Metastatic lesions that were resected after vaccination showed brisk or focal T-lymphocyte and plasma cell infiltrates with tumor necrosis in 10 of 16 patients. One complete, one partial, and one mixed response were noted. Ten patients (29%) are alive, with a minimum follow-up of 36 months; four of these patients have no evidence of disease.Conclusion: Vaccination with irradiated, autologous melanoma cells engineered to secrete GM-CSF by adenoviral-mediated gene transfer augments antitumor immunity in patients with metastatic melanoma.

PURPOSE To determine the maximum-tolerated dose (MTD) of 4'-epidoxorubicin (EPI) in combination with full dose of ifosfamide (IFO) when granulocyte-macrophage colony-stimulating factor (GM-CSF) was used, to estimate its clinical efficacy, and to evaluate the mobilization of hematopoietic progenitors. PATIENTS AND METHODS Previously untreated advanced patients were treated with fixed doses of IFO at 1.8 g/m2/d for 5 days and escalating doses of EPI. The starting dose level of EPI was 50 mg/m2 bolus on days 1 and 2; subsequent levels were 60 mg/m2 and 70 mg/ m2 given on days 1 and 2. GM-CSF (5 micrograms/kg/d) was administered from days +6 to +19. Clinical evaluation of response was performed after three consecutive cycles. Mobilization of hematopoietic progenitors was evaluated as day 14 CFU-GM after the first cycle only. RESULTS Overall, six, 18, and 13 assessable patients were entered onto each EPI dose level, respectively. The first and the second EPI level were considered feasible. Conversely, at the third level, only six of 13 patients [46%] tolerated full EPI doses at the scheduled time. Therefore, the dose-intensity of the three levels was 100%, 99.7%, and 86.1%, respectively. Overall, 20 of 37 patients (54%) obtained an objective response. The response rates for the three EPI dose levels were significantly different [17%, 33%, and 100%, respectively; test for trend, P < .001]. Considering only lung metastases, the overall response rate was 72% (20%, 66%, and 100% for the three EPI levels, respectively). The most relevant mobilization effect was obtained at the third EPI level, when both GM-CSF and IL-3 were used as in vitro-stimulating factors. CONCLUSION The third EPI level (70 mg/m2 on days 1 and 2) is the MTD of this program, since it was administered, without dose reduction or treatment delay, for three consecutive cycles in less than half of the patients. Nevertheless, this level proved to be interesting with regard to response rate (13 of 13 objective responses) and in mobilization of the hematopoietic progenitors.

Abstract Background: Despite advances in chemotherapy, R/R HL remains a significant clinical problem with over 1,000 primarily young lives lost annually. HL is a unique tumor in which a small number of malignant Hodgkin Reed-Sternberg (HRS) cells propagate an immunosuppressive microenvironment that augments HRS growth and survival. We hypothesized that immune checkpoint inhibitor therapy could activate the tumor immune microenvironment, while the CD30 expressing HRS cells could be targeted by brentuximab vedotin (BV), thereby overcoming tumor cell resistance and deepening clinical responses. E4412 is a phase 1 ECOG-ACRIN sponsored study of the combination of BV and the checkpoint inhibitors ipilimumab (IPI) and nivolumab (NIVO) in patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL). Here we report the data on the patients treated with BV + IPI, the first cohort of the study. Methods: Patients with biopsy proven R/R HL were treated with BV 1.8mg/kg and two escalating doses of IPI: 1 mg/kg or 3mg/kg. After safety was determined an expanded cohort was treated with BV 1.8mg/kg IV and IPI 3mg/kg IV. The schedule consisted of BV administered every 21 days for 16 cycles and IPI every 21 days x 4 doses and thereafter every 3 months for up to a year. Dose limiting toxicity (DLT) was defined for purposes of dose escalation within the first cycle of therapy. Patients are followed for toxicity up to 30 days beyond their last treatment. Results: As of 7/2015 19 of 23 planned patients have been treated with BV + IPI. We report the data on the full dose escalation population (13 patients: Dose level 1 (6), Dose level 2 (7)). The median age was 33 years (range: 20-49). Seven patients were male. Patients were heavily pretreated with a median of 4 prior therapies (2-13). Fourpatients had prior treatment with BV; 8 patients had prior SCT (7 autologous, 1 allogeneic). Safety: Overall the regimen of BV + IPI was extremely well tolerated with no DLTs noted during dose escalation. Toxicities considered at least possibly related to drug during any cycle of treatment are shown according to grade in Table 1. The most common treatment related adverse events were: diarrhea, rash, and peripheral sensory neuropathy. Other AEs of interest included: alopecia, transaminitis, and uveitis. Grade 3 and 4 treatment related adverse events (AEs) included: Dose level 1: one grade 3 infusion reaction, which led to a protocol amendment to include premedication, no further grade 3 infusion reactions were noted; Dose level 2: one each: grade 3 rash, vomiting, and peripheral sensory neuropathy, and one grade 4 thrombocytopenia in patient with pre-existing thrombocytopenia. Response: For the 12 evaluable patients, the overall response (ORR) for the combination of BV + IPI was 67% with a complete response (CR) rate of 42% (5 of 12 patients). An additional 2 patients had stable disease (SD) giving a clinical benefit rate of 83%. Three of 5 of the CRs occurred at dose level 1 (1mg dose of IPI). The median progression free survival (PFS) is 0.74 years with a median follow-up of 0.66 years. Conclusion: In this first reported study of the combination of checkpoint inhibitor and ADC, toxicity was low, primarily grades 1 and 2. In a heavily pretreated patient population, 33% of whom had had prior BV and 67% of whom were s/p ASCT, the ORR of 67% and CR rate of 42% suggests a potential deepening of response compared to monotherapy. More than half of these CRs occurred at 1mg of IPI suggesting that in combination with ADC, low doses of immune stimulation may be highly active. Optimization of this combination strategy is planned with ongoing accrual to cohorts receiving BV + NIVO, and BV + IPI + NIVO. Data will be updated to include the full BV + IPI cohort by the time of the annual meeting. Table 1.

Abstract The prognosis of patients (pts) with relapsed/ refractory acute lymphoblastic leukemia (ALL) remains poor and novel therapies are needed. The anti-CD22 immunoconjugate inotuzumab ozogamicin (INO) has demonstrated promising results in both phase 2 and 3 trials (Kantarjian et al. Lancet Oncology 2012; 13(4): 403-11). Pre-clinical studies have demonstrated superior anti-tumor activity when INO is co-administered with cyclophosphamide (C), vincristine (V), and prednisone (P). In this study, SWOG 1312, we assess the safety of INO in combination with CVP and determine the maximum tolerated dose (MTD) of INO in this regimen for patients with relapsed or refractory (R/R) CD22+ acute leukemia (B-ALL, mixed phenotype, and Burkitts). Here, we present our toxicity results. Methods: Pts were treated at limited SWOG institutions from Apr 2014 to present. INO was supplied by Pfizer and an IND was approved by the FDA. The protocol was reviewed and approved by each institutional review board. Eligibility criteria included: age > 18 years (yrs), > 20% blasts expressing CD22, R/R CD22+ acute leukemia (B-ALL, mixed phenotype, or Burkitts), and adequate organ function. All pts received treatment with C (750 mg/m2) intravenous (IV) Day 1, V (1.4 mg/m2) (max 2 mg) IV Day 1, P (100 mg) orally Days 1-5 and IO (dose escalated as in Table 1) IV Days 1, 8, and 15. Each cycle was 28 days, and a maximum of 6 cycles could be administered. Dose escalation was performed using a standard 3x3 design; with the plan to treat 12 pts once the MTD was defined. Dose limiting toxicities (DLTs) were considered: (1) > Grade 4 non-hematologic toxicities with the exception of nausea, vomiting and toxicities secondary to neutropenia and sepsis; (2) prolonged myelosuppression [absolute neutrophil count (ANC) < 500/ uL or platelet count < 25,000/uL] in a bone marrow with < 5% blasts and no evidence of leukemia that lasts > 35 days beyond the most recent dose of IO; (3) any grade 3 non-hematologic toxicity (excluding peripheral neuropathy, hyperglycemia, and toxicities secondary to neutropenia, thrombocytopenia, and sepsis) that does not resolve to Grade 2 or better by 7 days beyond the most recent dose of IO; (4) any > Grade 3 elevation in SGOT/ SGPT or bilirubin lasting ≥ 7 days; (5) any IO-related toxicity resulting in permanent discontinuation of IO. Results: As of 7/14/2016, 24 pts have been enrolled: 2 pts were ineligible and 3 pts are currently receiving treatment and are not evaluable for toxicity. Of the 19 evaluable pts, the median age was 49 yrs (range 21-75), 10 (53%) were male, and the median WBC at registration was 9.4 K/uL (range 0.9-59.6). All pts had B-ALL. The median time from initial diagnosis to registration was 774 days. Five pts were in 1st relapse, 8 in 2nd relapse, 3 in 3rd relapse, 1 in 4th relapse, and 2 pts were primary refractory. Five pts had received prior allogeneic hematopoietic stem cell transplant (AHSCT); 7 pts had poor risk cytogenetics (Ph+, -7, +8, complex, or hypodiploid). One death occurred during treatment and was attributed to pneumonia. Grade 3-4 hematologic toxicity related to treatment was common: neutropenia (11 pts), thrombocytopenia (7 pts), and anemia (6 pts). Grade 3-4 non-hematologic toxicities were almost exclusively febrile neutropenia. One DLT occurred at Dose Level 3: prolonged myelosuppression. No cases of hepatic veno-occlusive disease (VOD) occurred during treatment, and 1 pt experienced Grade 3 alkaline phosphatase at Dose Level 1. Three pts proceeded to AHSCT after study treatment; 1 pt developed VOD post AHSCT however, this fully resolved. Currently, 3 pts have been enrolled to Dose Level 4. Conclusion: The combination of CVP/IO is well tolerated and only 1 significant hepatic event (which subsequently resolved) was observed despite a heavily pre-treated group of patients. Further toxicity results and dose escalation will be presented at the meeting. Response data will also be presented if enrollment is complete.

13168 Background: Triapine (T) is a novel ribonucleotide reductase inhibitor, affecting the M2 subunit. It has in vitro and in vivo antitumor activity. Hematologic toxicity was dose limiting in single agent phase I trials. Triapine potentiates the activity of DNA damaging agents such as doxorubicin (D), with synergy demonstrated in vivo. Methods: D was administered on day 1 and T was administered on days 1–4 of a 21-day cycle. Patients enrolled in cohorts of three, beginning at D60 mg/m2 and T25 mg/m2. Dose limiting toxicity was defined as grade 3 or 4 leukopenia or thrombocytopenia lasting 7 days, febrile neutropenia or grade 3 or 4 non-hematologic toxicity. Results: Fourteen patients have enrolled in four dose cohorts, receiving 23 courses. At dose level 2 (D60 mg/m2, T45 mg/m2), two patients experienced DLT (febrile neutropenia, grade 4 thrombocytopenia). An additional 3 patients enrolled at dose level one without initial toxicity. Enrollment then resumed at dose level 2a with a decreased dose of doxorubicin (D45 mg/m2, T45 mg/m2). Two patients enrolled on this level had DLT. Enrollment was planned to resume at dose level 1 (D60 mg/m2, T25 mg/m2); however, the sixth patient enrolled to this cohort developed grade 5 heart failure (ejection fraction 20%, pretreatment EF 62%) after the second course. Enrollment has begun at doses of D45 mg/m2 and T25 mg/m2. Hematologic toxicity has predominated, with 52% of courses having grade 3 or 4 neutropenia. Non-hematologic toxicity included grade 2 fatigue in 17% of courses and 1 episode of grade 5 heart failure. Although no objective antitumor responses have been seen, 1 patient with metastatic melanoma had stable disease through 6 cycles of treatment. Another patient with previously rapidly progressive metastatic melanoma had stable disease for over 2 months of treatment. Conclusions: The combination of triapine and doxorubicin appears to have increased toxicity. Enrollment continues. [Table: see text]

2605 Background: AKT plays a key role in the survival, resistance, and overall aggressive pathogenesis of HER2+ malignancies, suggesting that AKTis may be of therapeutic value. MK2206 is a selective allosteric AKTi that has demonstrated synergy in combination with both H and P in preclinical studies. Methods: We conducted a phase 1b study of MK2206 in combination with weekly P 80 mg/m2 and H 2 mg/kg in pts with HER2+ solid tumors. MK2206 was given orally at a starting dose of 135 mg once a week (QW). Dose escalation was performed using a modified Ji method. The maximum tolerated dose (MTD) was defined as the dose level resulting in 3 or fewer dose limiting toxicities (DLTs) in 11 pts, then confirmed in 4 additional pts. Circulating tumor cells and PK samples were collected for all pts. Results: A total of 17 pts were enrolled, and 15 pts were evaluable for toxicity. All pts had HER2+ tumors (11 breast, 3 gastric, 1 esophageal). Based on interim toxicity data from other studies, the dose of MK2206 was not escalated beyond 135 mg QW. All 15 pts were treated at this dose level which was determined to be tolerable. Two DLTs were observed including grade 3 rash and grade 3 neutropenia resulting in a >7 day treatment delay. There were no severe adverse events (AEs) related to study treatment. Other grade 3/4 AEs were neutropenia (6 pts), febrile neutropenia (1 pt), peripheral neuropathy (1 pt), and depression (1 pt). The most common all-grade AEs include rash (13 pts), hyperglycemia (13 pts), neutropenia (13 pts), peripheral neuropathy (10 pts), diarrhea (9 pts), fatigue (9 pts), anorexia (9 pts), stomatitis (7 pts). Of the 14 pts evaluable for response, 9 pts (64%) had tumor response (2 CR, 7 PR), and 4 pts had SD. The median duration of response was 5.5 months. Pts were heavily pretreated (median lines of prior therapy 3, 11 prior taxane, 12 prior H). Conclusions: MK2206 at a dose of135 mg QW in combination with weekly P and H is safe and well-tolerated. 135 mg QW is the recommended phase 2 dose for this combination. Preliminary data indicate significant clinical activity in pts with HER2+ tumors despite extensive prior therapy. MK2206 is now being tested in the neoadjuvant ISPY2 trial. Clinical trial information: NCT01235897.
