Abstract
9016 Background: Teliso-V is an antibody-drug conjugate composed of a c-Met antibody (ABT-700) and a microtubule inhibitor (monomethyl auristatin E). The phase 2 M14-239 trial (LUMINOSITY, NCT03539536) aims to identify the c-Met OE NSCLC populations best suited to Teliso-V (Stage 1) and expand selected groups for further evaluation of efficacy (Stage 2). In Stage 1, pts were enrolled into cohorts defined by histopathology (non-squamous [NSQ] or squamous [SQ]) and EGFR mutation status (mutant or wild type [WT]); NSQ cohorts were further divided in groups on the basis of c-Met expression (high or intermediate). Updated data from the fourth interim analysis (IA4) are presented. Methods: Pts had locally advanced/metastatic NSCLC, ≤2 prior lines of systemic therapy, ≤1 line of chemotherapy, and tumors that were c-Met OE by central immunohistochemistry (IHC; Ventana; Tucson, AZ). c-Met OE was defined for the NSQ cohort as ≥25% 3+ by IHC (high, ≥50% 3+; intermediate, 25 to <50% 3+) and for the SQ cohort as ≥75% 1+ by IHC. The planned enrollment was up to approximately 150 pts in Stage 1 and 160 pts in Stage 2. Teliso-V was dosed at 1.9 mg/kg IV Q2W. The primary endpoint is objective response rate (ORR) by independent central review. Secondary endpoints include duration of response (DOR). Results: As of data cutoff (27 May 2021), 136 pts were treated with Teliso-V; 122 were evaluable for ORR. ORR was 36.5% in the NSQ EGFR WT cohort (52.2% in c-Met high group and 24.1% in c-Met intermediate group), but was modest in the NSQ EGFR mutant and SQ cohorts. Efficacy data in groups/cohorts are in the Table. The most common any-grade adverse events (AEs) were peripheral sensory neuropathy (25.0%), nausea (22.1%), and hypoalbuminemia (20.6%). Grade 5 AEs considered possibly related to Teliso-V occurred in 2 pts (sudden death and pneumonitis in 1 pt each in the SQ cohort). Conclusions: Teliso-V demonstrated a promising ORR in pts with previously treated c-Met OE NSQ EGFR WT NSCLC; this cohort is currently expanding in Stage 2. ORR was modest in the cohorts of pts with c-Met OE NSQ EGFR mutant NSCLC and with c-Met OE SQ NSCLC; both cohorts have now met the protocol-specified stopping criteria and are no longer enrolling. The safety profile observed was consistent with IA3. Clinical trial information: NCT03539536. [Table: see text]

Abstract
Paediatric Strategy Forums have been created by the multistakeholder organisation, ACCELERATE, and the European Medicines Agency to facilitate dialogue between all relevant stakeholders and suggest strategies in critical areas of paediatric oncology drug development. As there are many medicines being developed for B-cell malignancies in adults but comparatively few in children with these malignancies, a Paediatric Strategy Forum was held to discuss the best approach to develop these products for children. It was concluded that as current frontline therapy is highly successful, despite associated acute toxicity, de-escalation of this or substitution of presently used drugs with new medicines can only be undertaken when there is an effective salvage regimen, which is currently not available. Therefore priority should be given to developing treatment for patients with relapsed and refractory mature B-cell lymphomas. The consensus of the clinicians attending the meeting was that CAR T-cells, T-cell engagers and antibody drug conjugates (excluding those with a vinca alkaloid-like drug) presently have the greatest probability of providing benefit in relapse in view of their mechanism of action. However, as producing autologous CAR T-cells currently takes at least 4 weeks, they are not products which could be quickly employed initially at relapse in rapidly progressing mature B-cell malignancies but only for the consolidation phase of the treatment. Global, industry-supported, academic-sponsored studies testing compounds from different pharmaceutical companies simultaneously should be considered in rare populations, and it was proposed that an international working group be formed to develop an overarching clinical trials strategy for these disease groups. Future Forums are planned for other relevant paediatric oncologic diseases with a high unmet medical need and relevant molecular targets.

Abstract
Cetuximab in combination with an irinotecan-containing regimen is a standard treatment in patients with KRAS wild-type (KRAS WT), metastatic colorectal cancer (mCRC). We investigated the addition of the oral MET inhibitor tivantinib to cetuximab + irinotecan (CETIRI) based on preclinical evidence that activation of the MET pathway may confer resistance to anti-EGFR therapy. Previously treated patients with KRAS WT advanced or mCRC were enrolled. The phase 1, open-label 3 + 3, dose-escalation study evaluated the safety and maximally tolerated dose of tivantinib plus CETIRI. The phase 2, randomized, double-blinded, placebo-controlled study of biweekly CETIRI plus tivantinib or placebo was restricted to patients who had received only one prior line of chemotherapy. The phase 2 primary endpoint was progression-free survival (PFS). The recommended phase 2 dose was tivantinib (360 mg/m(2) twice daily) with biweekly cetuximab (500 mg/m(2)) and irinotecan (180 mg/m(2)). Among 117 patients evaluable for phase 2 analysis, no statistically significant PFS difference was observed: 8.3 months on tivantinib vs. 7.3 months on placebo (HR, 0.85; 95% confidence interval, 0.55-1.33; P = 0.38). Subgroup analyses trended in favor of tivantinib in patients with MET-High tumors by immunohistochemistry, PTEN-Low tumors, or those pretreated with oxaliplatin, but subgroups were too small to draw conclusions. Neutropenia, diarrhea, nausea and rash were the most frequent severe adverse events in tivantinib-treated patients. The combination of tivantinib and CETIRI was well tolerated but did not significantly improve PFS in previously treated KRAS WT mCRC. Tivantinib may be more active in specific subgroups.

Abstract
3508 Background: Tivantinib (ARQ 197) selectively inhibits the MET receptor tyrosine kinase, which is implicated in tumor cell migration, invasion, and metastasis. Resistance to EGFR inhibitors has been associated with activation of alternative pathways including MET. Methods: Pts with advanced KRAS WT CRC that progressed on or after 1 prior line of chemotherapy and no previous treatment with an EGFR inhibitor were eligible. Pts were randomized 1:1 to receive cetuximab (500 mg/m2) and irinotecan (180 mg/m2) on days 1 and 15 every 28 days, plus oral tivantinib (360 mg twice daily [BID]) or placebo. The primary endpoint was progression-free survival (PFS); additional endpoints include safety, objective response rate, overall survival (OS) and exploratory biomarker analyses. Results: Between Jul 2010 and Feb 2012, 122 pts were randomized; 117 pts were eligible for analysis (60 tivantinib, 57 placebo). Mean age was 57 years (range, 27-79 years); ECOG PS 0/1 55%/45%; and 81% received prior oxaliplatin. Median PFS was 8.3 months in the tivantinib arm vs 7.3 months in the placebo arm (hazard ratio [HR] = 0.85; 95% CI, 0.55-1.33; P = 0.38). Objective response rate (95% CI) was 45% (33%-58%) in the tivantinib arm and 33% (23%-46%) in the placebo arm. Median OS has not yet been reached but is trending in favor of tivantinib vs placebo (HR = 0.67). Among pts with prior oxaliplatin therapy, median PFS was 8.4 months for tivantinib and 7.2 months for placebo (HR = 0.67; 95% CI, 0.44-1.00; P= 0.1). The most common grade 3/4 adverse events (≥ 10%) were neutropenia, diarrhea, and nausea. Correlation of clinical outcomes with additional factors including mutation status and immunohistochemical analysis of tumor MET expression will be presented. Conclusions: Outcomes in this trial trended towards improvement with tivantinib (360 mg BID) plus cetuximab and irinotecan, particularly in the subgroup who had previous oxaliplatin. Further studies are needed to identify the CRC population most likely to benefit from addition of tivantinib to standard therapy. Clinical trial information: NCT01075048.

Abstract
BACKGROUND Transplant-associated thrombotic microangiopathy (TMA) syndromes are reported to occur with increased frequency in transplant patients treated with siroliumus combined with a calcineurin inhibitor. We performed a retrospective study of all pediatric transplant patients at City of Hope who were administered combined tacrolimus/sirolimus (TAC/SIR) to determine the occurrence of TMA. PROCEDURE This analysis includes 41 consecutive patients between the ages of 2 and 20 (median age 9.1) who received an allogeneic hematopoietic stem cell transplant from any source and also received TAC/SIR for prevention or treatment of GVHD. Of those 41 patients, 20 received TAC/SIR as GVHD prohpylaxis and were designated the preventative group (PG), while 21 received TAC/SIR as treatment for GVHD and were designated the therapy group (TG). TMA occurrence in both groups was documented from day -1 of transplant to day 60 for the PG, and until 30 days after last dose for the TG. TMA was defined according to 2005 consensus criteria. RESULTS Five of twenty patients in the PG, and five of twenty one in the TG, experienced TMA, with an overall rate of 23.8% for the population. All ten patients with TMA showed elevated levels of TAC, SIR or both and nine of ten suffered from organ injury due to regimen-related toxicity or GVHD. CONCLUSION Physicians should exercise caution in the use of TAC/SIR in pediatric patients due to a high rate of TMA. It is not recommended for heavily pre-treated patients and peak levels of TAC/SIR must be very carefully controlled.

Abstract
In the era of cytomegalovirus (CMV)-preemptive therapy, it is unclear whether CMV serostatus of donor or recipient affects outcome of allogeneic hematopoietic stem cell transplantation (HSCT) among children with leukemia. To investigate, consecutive patients aged 0-18 who underwent primary HSCT for acute leukemia in 1997-2007 (HLA-matched sibling or unrelated donor, myeloablative conditioning, unmanipulated bone marrow or peripheral blood, preemptive therapy, no CMV prophylaxis) were followed retrospectively through January 2008. Treatment failure (relapse or death) was analyzed using survival-based proportional hazards regression. Competing risks (relapse and nonrelapse mortality, NRM) were analyzed using generalized linear models of cumulative incidence-based proportional hazards. Excluding 4 (2.8%) patients lacking serostatus of donor or recipient, there were 140 subjects, of whom 50 relapsed and 24 died in remission. Pretransplant CMV seroprevalence was 55.7% in recipients, 57.1% in donors. Thirty-five (25.0%) grafts were from seronegative donor to seronegative recipient (D-/R-). On univariate analysis, D-/R- grafts were associated with shorter relapse-free survival (RFS) than other grafts (median 1.06 versus 3.15 years, P < .05). Adjusted for donor type, diagnosis, disease stage, recipient and donor age, female-to-male graft, graft source, and year, D-/R- graft was associated with relapse (hazards ratio 3.15, 95% confidence interval 1.46-6.76) and treatment failure (2.45, 1.46-4.12) but not significantly with NRM (2.00, 0.44-9.09). In the current era, children who undergo allogeneic HSCT for acute leukemia have reduced risk of relapse and superior RFS when recipient and/or donor is CMV-seropositive before transplantation. However, no net improvement in RFS would be gained from substituting seropositive unrelated for seronegative sibling donors.

Abstract
The purpose of the study was to evaluate the feasibility and safety of two cycles of high-dose chemotherapy (HDT) followed by autologous hematopoietic SCT (HSCT) in patients with poor prognosis Ewing family of tumors (EFT). Twenty patients with primary metastatic bulky disease or recurrent EFT were enrolled to a treatment protocol with two cycles of HDT and HSCT. Patients tolerated well the first (n=20) and second (n=13) cycles, with limited and predictable toxicities. Only one (5%) TRM occurred during the second cycle. Myeloid engraftment occurred at the median of 11 days after both cycles. At 3 years, the overall and EFS were 45% (confidence interval; CI 0.22, 0.69) and 47% (CI 0.25, 0.70), respectively, for the entire group and 58% (CI 0.30, 0.86) for patients who completed two cycles. Dose intensification with two cycles of HDT and HSCT is feasible and safe, with low and acceptable treatment-related morbidity and mortality. Adding a second course of therapy does not impair engraftment. However, only 65% of the patients were able to proceed to the second cycle. Further studies are required to define the optimal mode of delivery of HDT and HSCT in treatment of advanced EFT.

Abstract
The use of high-dose chemotherapy followed by autologous HCT and the use of allogeneic HCT in children and adolescents with high-risk ALL, AML, and NBL has successfully improved outcomes. For other diseases, however, the role of HCT in treatment remains a subject of further research. The availability of HCT was significantly expanded by developing alternative graft sources that currently include BM, peripheral blood, and UCB from autologous and allogeneic related or unrelated donors. Progress in autologous HCT has been achieved by the identification of more effective and less toxic preparative regimens and by ex vivo purging of stem cell products. In allogeneic HCT, graft-versus-leukemia or graft-versus-tumor effects are being exploited increasingly to lower relapse rates. In addition, immunomodulation to promote tolerance, as well as allogeneic antitumor reactions have been achieved by antibody therapy, cytokine therapy, or cell-based immunotherapy. Future improvements are likely, as evidenced by promising preliminary results in the development of stem cell collection techniques, in vitro stem cell expansion, and purging techniques of stem cell grafts. The development of less intensive or nonmyeloablative preparative regimens may further reduce regimen-related morbidity and mortality Specific immunotherapy may facilitate tolerance induction in mismatched allogeneic HCT and support allogeneic HCT in the setting of donor-host HLA disparity. Ultimately, advances in cytokine therapy, tumor-specific vaccines, and gene therapy may decrease or even eradicate recurrence of the malignant disease after HCT.

Abstract
IL-7 is produced by stromal cells and is the major lympho- and thymopoietic cytokine. IL-7 induces proliferation and differentiation of immature thymocytes, and protects thymocytes from apoptosis by induction of bcl-2 expression. The regulation of IL-7 production is poorly characterized, although down-regulation by transforming growth factor-beta (TGF-beta) has been described. We measured the serum levels of IL-7 before and after bone marrow transplant (BMT) in 32 children undergoing BMT for genetic diseases (severe combined immune deficiency (SCID) and thalassemia), aplastic anemia, and acute lymphoblastic and non-lymphoblastic leukemia (ALL and ANLL). Prior to BMT, the highest IL-7 levels were observed in patients with SCID and ALL, i.e. those patients with genetic or acquired lymphopenia. Patients with thalassemia and ANLL had normal levels of IL-7. Over the 8 weeks following BMT, the IL-7 levels of patients with SCID and ALL fell as the absolute lymphocyte count (ALC) increased. No detectable change in IL-7 levels was observed in the patients with thalassemia and ANLL. Levels of IL-7 were highest in the young infants with SCID compared to the age-matched controls. Together, the data demonstrate that serum levels of IL-7 in lymphopenic patients are inversely related to patient age and the absolute lymphocyte count (ALC). The inverse relationship to ALC suggests that there is either direct regulation of stromal production or more likely, binding of secreted IL-7 to lymphocytes expressing IL-7 receptors.

Abstract
Bone marrow transplantation (BMT) is followed by a period of profound immune deficiency, during which new T lymphocytes are generated from either stem cells or immature thymic progenitors. Interleukin-7 (IL-7) induces proliferation and differentiation of immature thymocytes. We examined whether the in vivo administration of IL-7 to mice receiving BMT would alter thymic reconstitution. Lethally irradiated C57BL/6 mice received syngeneic BMT, followed by either IL-7 or placebo from days 5 to 18 post-BMT. At day 28, BMT recipients that had not received IL-7 had profound thymic hypoplasia (< 5% of normal), with relative increases in the numbers of immature thymocytes, decreased numbers of mature peripheral (splenic) T lymphocytes, and severely impaired T- and B-cell function. In contrast, transplanted mice treated with IL-7 had normalization of thymic cellularity, with normal proportions of thymic subsets and T-cell receptor beta variable gene (TCRV beta) usage, normal numbers of peripheral CD4+ T lymphocytes, and improved antigen-specific T- and B-cell function. In the BMT-IL-7 mice, there was an eightfold increase in the number of immature CD3-CD4-CD8- thymocytes in G2-M of the cell cycle, indicating that restoration of thymic cellularity was due to enhanced proliferation of immature thymic progenitors. Similar effects following IL-7 administration were also observed when donor bone marrow was depleted of mature T lymphocytes, indicating that IL-7 administration affected immature hematopoietic progenitors. IL-7 promotes thymic reconstitution after BMT, and may be useful in preventing post-BMT immune deficiency.
