Abstract Background: Bortezomib is one of the most active drugs for the treatment of multiple myeloma and there are evidences that its activity is highly increased when it is used in combination with other drugs. We have already reported the activity of Bortezomib in combination with intravenous Melphalan (5 mg/m2) and Dexamethasone (BMD) in relapsed/refractory myeloma patients (ASH 2007, #2728). However, this scheme resulted in an elevated percentage of haematologic toxicity that prompted us to test the combination of Bortezomib with other less myelotoxic but active drugs such as Cyclophosphamide, and a liposomal Adryamicin. Methods: Bortezomib was given at dosage 1.3 mg/m2, and Dexamethasone 40 mg i.v. on days 1, 4, 8, 15 plus liposomal Adryamicin 20 mg i.v. on days 1 and 15, and Cyclophosphamide 100 mg per os for 15 days (1à15). An antibiotic and antiviral prophilaxis was guaranted to all patients with Bactrim and Acyclovir, and EPO and G-CSF were used as recommended. So far, 17 previously treated patients have been enrolled in this study, 4 males and 13 females. Median age was 63 (range 51–78), 7/17 patients were IIIA stage according to Durie and Salmon classification and 3/17 had extra-medullary disease. Five patients were resistant to previous therapies and 10 were relapsed. All patients had been already treated with a median of 2 previous lines of treatment (range 1–6). Four patients were in relapse within 12 months of stem-cell transplantation and 12 patients had already received Bortezomib alone or in combination. Six patients had been already treated with BMD (three were refractory, one in partial remission, and two relapsed) Results: After a median follow up of 5 months (range 1–8) 15/17 were valuable for response since they have received at least 2 cycles of therapy. 6/15 (40%) patients were considered responder: 3 patients had a very good partial remission (M-protein ≤ 90%), 3 patients a partial remission (M-protein >50%), 1 progressed, and 8 were in stable disease according to International Myeloma Working Group Criteria. Side effects were predictable and manageable; the most common grade 3/4 adverse events included hematologic toxicity (thrombocytopenia [18%], neutropenia [6%], anemia [6%]), paresthesia grade 2 in 3 patients and nausea and vomiting grade 3 in only one patient. So far, 1 patient has stopped treatment for progression disease, and only one for toxicity (infectious disease grade III), in both cases after 2courses. In table 1 the comparison of efficacy and toxicity between ABCD and BMD after 3 cycles is reported. ABCD seems to be as effective as BMD (considering that 1/3 of patients had been already treated with BMD) but with higher tolerability. Conclusion: The combination of liposomal Adryamicin, Bortezomib, Cyclophosphamide, and Dexamethasone (ABCD) is effective and well tolerated treatment even for heavily pretreated patients with poor prognostic features. The dosage of some drugs could be increased in order to maximize the overall response rate.

Background Pomalidomide is a new generation IMID, with a very good compliance, thanks to oral administration, which can be used also in heavily pretreated patients, in a domestic setting. Aims In this retrospective observational trial, It has been evaluated efficacy and tolerance of pomalidomide plus dexamethasone (PD) as salvage regimen in heavily pretreated patients with relapsed and refractory MM (rrMM), whose prognosis is particularly severe. Methods 57 patients (31 M/26 F), with rrMM, median age at diagnosis 69 years (r. 52-86), and median age at start of treatment 76 years (r.56-90) treated with several lines of treatments (median 7, r. 2-11), every refractory to all the drugs previously received (also Bortezomib, Thalidomide and Lenalidomide), received Pomalidomide-Dexamethasone (Pomalidomide 4 mg for 21 days, Dexamethasone 40 mg days 1,8,15,22, pegfilgrastim day +8) every 28 days, until progression. ISS was equally distributed, and cytogenetic at relapse was evaluable in 14 patients. All the patients had previously been treated with schedule containing bortezomib and IMIDs. 63% (36/57) had undergone at least to a single ASCT. All patients were relapsed and refractory to last therapies received before PD. Results Pomalidomide was well tolerated, with grade 3-4 transfusion-dependent anemia in 58% (33/57) of patients, 44% (23/57) grade 3-4 neutropenia (pegfilgrastim in primary prophylaxis was given, no hospitalization was required, no septic shocks were observed), 40% (23/57) grade 3-4 thrombocytopenia without hemorrhagic events and transfusion-dependence. No severe extra-hematologic toxicity was observed. According to IMWG, ORR1 (≥PR) was 47.3% (27/57: 5 CR, 11 VGPR, 7 PR, 4 MR), but, considering that we are evaluating a cohort of heavily pretreated patients, with poor prognosis, another parameter should be considered, ORR2 (≥SD), considering stable disease as a successful result in progressive MM. ORR2 was 77.1% (17 SD). These can be considered as impressive result in this subset of patients. Oral treatment gives a really good compliance, in frail and unfit patients, and response, when present, is always really fast (median time to response: 2 months (r.1-6)), median OS from diagnosis was 94 months (range 21-234), median OS from start of pomalidomide was 9 months (range 1-25). Nine patients have surprisingly achieved a notable response (3 VGPR, 4 PR, 2 MR) after failure of novel agents (i.e. Carfilzomib, Daratumumab and Pomalidomide). Conclusions Pomalidomide-dexamethasone has shown significant efficacy and a very good compliance, thanks to oral administration, in a particularly severe setting of heavily pretreated patients, relapsed and refractory to all available therapeutic resources, also after failure of novel agents.

Abstract The decision to treat indolent B-cell NHL is often based on progression of the disease. Most regimens have utilized fludarabine as the purine analog but the myelosuppression and immunosuppression of fludarabine combinations frequently results in severe infections. Combination therapy with pentostatin (P), a purine analog, cyclophosphamide (C), a DNA alkylator, and rituximab (R), an anti-CD20 monoclonal antibody, based on the single-agent activities, documented synergy, and non-overlapping toxicity profiles, may represent a promising approach in the treatment of these patients. To further investigate the efficacy of the PCR regimen for the treatment of indolent NHL, we conducted a phase II study. Patients diagnosed of bulky stage II, stage III/IV low-grade NHL (REAL classification), previously untreated or treated, were eligible. All patients were treated with intravenous infusions of P (4 mg/m2), C (600 mg/m2), and R (375 mg/m2) on day 1 of a 21-day cycle for at least 8 cycles. 2 additional cycles were given for patients with PR or SD after cycle 8 or patients with CR/CRu first evident at cycle 8. Clinical evaluation was performed after cycles 2, 4, 6, 8, and 10 if necessary. Dose modification for hematologic toxicity may be increased to the previous higher level when a hematologic toxicity returned to normal. Two 25% dose reductions or one 50% dose reduction were allowed for nonhematologic toxicity. One hundred patients with indolent NHL, 68 previously untreated, 26 previously treated, and 6 with unknown treatment history, were enrolled in the study. The median age was 61 years (range 29–84) and 63.4% were ECOG PS 0, 36.6% PS1. A total of 550 cycles were given, with a median of 6 cycles per patient. 8 patients were not evaluated for response due to withdrawal of consent (n=1), unacceptable toxicities (n=3), and missing data (n=4). 92 patients received at least two cycles of treatment and were evaluated for response. The highest response rate (RR) achieved was 68%, with 10 (10%) CR, 12 (12%) CRu, 46 (46%) PR, 23 (23%) SD, and 1 (1%) disease progression. Stratified according to previous treatment status, patients with previously untreated NHL had an RR of 47% (CR, CRu 17%) while that of the previously treated was 17% (CR 7%). 14 (14.0%) patients discontinued treatment due to toxicities. Grade 3/ 4 hematological adverse events documented included 10 grade 4 and 16 grade 3 neutropenia. Infectious complications were noted in 8 patients including 3 grade 3 febrile neutropenia, 2 grade 4 febrile neutropenia, and 3 grade 3 infections. A total of 4 deaths were recorded, including 1 due to acute myocardial infarction, 1 suspected cardiac event and 2 unknown causes. This immunochemotherapeutic regimen is active in patients with indolent NHL. The study is currently on-going and updated results will be presented.

Abstract Introduction Mantle cell lymphoma (MCL) is characterized by cell cycle dysregulation due to cyclin D1 and CDK4 overexpression. Palbociclib (PD 0332991) is an orally bioavailable, specific, reversible inhibitor of CDK4/6 that induces prolonged early G1 arrest (pG1) in MCL cells and durable remissions in patients with MCL. Moreover, we have evidence that palbociclib-induced pG1 sensitizes MCL cells to killing by bortezomib and that sensitization is amplified upon withdrawal of palbociclib, when MCL cells synchronously enter S phase (pG1-S). Targeting CDK4 in combination with bortezomib, therefore, is a rational and novel therapeutic combination. We report the final results of a phase I trial of palbociclib plus bortezomib in patients with previously treated MCL. Methods Adults with previously treated MCL and adequate bone marrow and organ function were received palbociclib orally at doses of 75 mg (dose level 1), 100 mg (dose level 2), or 125 mg (dose levels 3 and 4) for 12 days. Bortezomib was administered by IV or SC injection at 1 mg/m2 (dose levels 1-3) or 1.3 mg/m2 (dose level 4) on days 8, 11, 15, and 18 of each 21-day cycle. Subjects underwent core needle biopsies of tumor tissue pre-treatment, on day 8 (in pG1) and on day 21 (in pG1-S phase) of cycle 1. Subjects were restaged following cycles 2, 5, and 8 and then every 4 cycles. Subjects could remain on the study regimen until progression, unacceptable toxicity, or withdrawal. Dose levels were escalated according to the standard 3+3 schema. Dose limiting toxicity (DLT) was defined as treatment-related grade 3-4 toxicity occurring during cycle 1 or a delay in cycle 2 of > 1 week due to treatment-related grade 4 neutropenia or thrombocytopenia. The primary objective was to estimate the maximum tolerated dose of the combination. Secondary objectives included response rate, duration of response, and evaluation of the pharmacokinetic and pharmacodynamic profiles at multiple time points and across all dose levels. Results Nineteen subjects were enrolled: 6 in dose level 1, 3 in dose level 2, 7 in dose level 3, and 3 in dose level 4. The median age was 64 years (range 42-81). The median number of prior therapies was 3 (range 1-7). The number of subjects with low, intermediate, and high-risk MIPI scores was 6, 11, and 2, respectively. Two subjects experienced DLT: thrombocytopenia (level 1), neutropenia (level 3). Grade 3-4 hematologic toxicity included neutropenia (63%), thrombocytopenia (53%), lymphopenia (32%), and anemia (11%). Treatment-related grade 3-4 non-hematologic toxicity included zoster (1). Grade 1-2 toxicities occurring in >2 pt included: fatigue (47%), pain (42%), bleeding/bruising (37%), increased creatinine (26%), constipation (26%), rash (21%), nausea/vomiting (21%), sensory neuropathy (21%), dyspnea (21%), hypoalbuminemia (16%), cough (16%), edema (16%), infection (16%), increased AST (16%), hypocalcemia (16%), increased alk phos (16%). Reasons for ultimately stopping treatment include: progression (9), toxicity (6), and non-compliance (1). All 3 patients at dose level 4 required dose delays/reductions during cycle 2 due to toxicity. There appeared to be an association with dose of palbociclib and response, with one responder at each of dose levels 1 and 2, and 4 patients remaining free from progression for 1 year at dose level 3, including one complete response. Only one responding patient progressed on therapy. All patients with serial biopsies achieved pG1 on day 8, with reduction in CDK4/CDK6-specific Rb phosphorylation and Ki67 by immunohistochemistry. The primary MCL tumor cells express cell cycle genes scheduled for early G1 such as cyclin D1 and CDK4, but not genes programmed for other phases of the cell cycle such MKi67, E3F3, CDK1, CCNA2, as determined by RNA-seq. Conclusion Daily palbociclib 125 mg for 12 days can be safely combined with bortezomib 1 mg/m2 twice weekly, while higher doses were limited by myelosuppression. The combination induced durable responses in some patients. Palbociclib induced pG1, even at the lowest dose. However, the initial cell cycle control by palbociclib did not predict clinical response. Rather, pG1 appears to induce an imbalance in gene expression that is associated with response to the combination of palbociclib plus bortezomib. Strategies to control the cell cycle and dissect the underpinning mechanisms appear promising in MCL and warrant further evaluation.

15501 Background: This study was to assess the efficacy and safety profiles of the combination treatment with S-1 and Cisplatin in patients with locally advanced SCCHN. Methods: Eligible patients were defined as histologically confirmed SCCHN, stage III or IV with no evidence of distant metastasis, evaluable lesions, adequate organ function, age of 20–80 years, and performance status 0,1 or 2. Cisplatin was infused over 1 hour on day 1 (75 mg/m2) and S-1 was administered orally for 14 consecutive days (day 2–15). The dosages of S-1 were assigned according to the patients’ body surface area (BSA): 50 mg twice a day (BSA < 1.5m2), 60 mg twice a day (BSA > 1.5m2). Each course was repeated every 3 weeks. After 2 course, tumor response were evaluated by CT scan and laryngoscopy. If the patients achieved a response (complete response: CR, or partial response: PR), they received one more course of chemotherapy before undergoing the radiotherapy or operation as a definitive local treatment. Results: All 22 patients were assessable for response and toxicity. The overall response was 80.9% (CR: 3, PR: 14). The adverse reactions occurred 120 times in 54 courses of 22 cases. The most common grade 3/4 adverse events were neutropenia, which occurred in 8 patients. Non-hematological toxicity of grade 3 and 4 included nausea and vomiting in 4 patients, fever in one patient and, fatigue in one patient. Since the observation period is short, the analysis about survival rate is not obtained so far. Conclusions: S-1 plus Cisplatin combination chemotherapy is effective against locally advanced SCCHN with mild toxicity. No significant financial relationships to disclose.

18200 Background: Docetaxel(D) has been shown to improve overall survival in pts with previously treated NSCLC. Pre-clinical data suggest synergistic activity with the combination of D and I. Paul Matthew; et al demonstrated the safety of this combination in pts with prostate cancer. Methods: This is a Phase II study of the combination of D and I in prev tx NSCLC to determine response rate, toxicity and assess overall survival. Pts must have received at least 1 prior regimen and have an ECOG PS of 2 or less. Prior tx with D was allowed. D was admin at 30 mg/m2 on a weekly schedule for 3 weeks followed by 1 week rest. I was admin at a starting dose of 600 mg/day throughout the study. Results: A total of 10 pts were enrolled. Seven male and 3 female with a median age of 66 years (range 58 - 74). A total of 26 cycles were delivered to 10 pts (mean = 3). Responses included 1 PR/3SD/2PD/4NE. One pt with a PR responded after cycle 4 but progressed after cycle 6. One pt maintained SD for 21 wks then expired due to an unrelated PE (h/o peripheral vascular disease). Grade 4 toxicity included periorbital edema (1 pt), pneumonia (2 pts), diarrhea (1 pt), dehydration (1 pt), dyspnea (1pt), anorexia (1 pt), pleural effusion (1 pt), and neutropenia (2 pts). Grade 3 toxicity included hyponatremia (1 pt), renal failure (1 pt), hypotension (2 pts), mental status changes (1 pt), anorexia (1 pt), azotemia (1 pt), dyspnea (1 pt), herpetic esophageal ulcer (1 pt), pneumonia (1 pt), neutropenia (2 pts), weakness & fatigue (1 pt), and anemia (1 pt). Four of 10 pts received only 1 cycle. (Three of those 4 suffered a fatal adverse event during cycle 1, not felt to be treatment related. The fourth developed herpetic esophageal lesions and was taken off study prior to tumor assessment.) Conclusions: The study was closed before the initial planned pts were enrolled due to low activity and unexpected high tox. Only 1 of 10 pts achieved a PR. Stable disease was observed in 3 pts but was of short duration in 2 of the 3. Despite supportive treatment, nausea, vomiting, diarrhea, and anorexia were difficult to control. Hematologic toxicity was encouragingly infrequent with only 2 pts experiencing Grade 4 neutropenia. Alternative dosing schedules would be recommended before pursuing this combination in NSCLC pts. Study supported by a grant from Novartis. No significant financial relationships to disclose.

679 Background: 5-fluorouracil (5-FU), a synthetic fluoropyrimidine, is a critical component of chemotherapy in many cancers. Its metabolites inhibit Thymidylate Synthetase (TS) causing cessation of DNA synthesis and are misincorporated into DNA and RNA causing ineffective DNA repair and faulty mRNA splicing. The rate limiting step in the catabolism of 5-FU is by the Dihydropyrimidine Dehydrogenase enzyme (DPD) which catabolizes over 80% of 5-FU. Patients with near total DPD enzymatic deficiency develop life threatening toxicity after a single administration and those with less severe deficiency will have delayed elimination of 5-FU and slowly accumulate active metabolites leading to toxicities. Methods: We conducted a pilot retrospective cohort study of African American (AA) and Caucasian patients treated for colorectal cancer over a 9 year period, 2000 – 2008, in this IRB approved study. The primary outcome of interest was the rate of development of grade 3 or 4 neutropenia (Absolute Neutrophil Count <1000/uL = grade 3 and <500/uL = grade 4). Descriptive and univariate analysis were done. To test for differences between AA and Caucasians, we computed independent t-test for continuous and Fisher’s exact test for categorical variables. Relative Risk (RR) and p-values were computed. All statistics were done with SPSS v19 software. Results: There were 66 evaluable patients (40 men, 26 women), 40 AA, 24 Caucasians and 2 of other races. Thirty-eight patients (15 Caucasians and 23 AA) received 5-FU containing chemotherapy. The two groups were comparable in baseline characteristics. AA were more likely to develop grade 3-4 hematological toxicity. Nine of 23 AA (39.1%) and one of 15 Caucasians (6.7%) developed grade 3-4 hematological toxicity. RR 8.56, 95% confidence interval 0.95 – 421.06 (p-value of 0.0561) Conclusions: These results suggest that AA were more likely than Caucasians to have severe hematologic toxicity with the use of 5-FU containing chemotherapy. This difference did not meet statistical significance due to small sample size and few numbers of events in the Caucasian arm. A larger prospective study is needed to further evaluate the observed difference.

TPS4692^ Background: The phase III TROPIC study (NCT00417079) reported a significant improvement in overall survival (OS) for cabazitaxel (Cbz) + prednisone (P;CbzP) (25 mg/m2 IV Q3W/10 mg PO QD) vs mitoxantrone (M) + P (MP) (median OS 15.1 vs 12.7 mos; HR 0.70; P < 0.0001) in pts with mCRPC (also known as hormone-refractory prostate cancer) previously treated with a D-containing regimen. CbzP is approved by the FDA, EMA and other health authorities for the treatment of pts with mCRPC that has progressed after a D-containing regimen. Cbz toxicity is consistent with other taxanes; compared with M, more hematologic toxicities are reported (primarily Grade 3–4 neutropenia). Phase I/II studies identified 20 and 25 mg/m2 as recommended doses; 25 mg/m2 was selected for the phase III TROPIC study. As pooled data show Grade 3–4 neutropenia incidence is lower with Cbz < 25 mg/m2 (61%) vs ≥ 25 mg/m2 (74%), it is of interest to assess if reducing the Cbz approved dose in mCRPC lessens hematologic toxicity and is non-inferior in terms of efficacy. Methods: PROSELICA (NCT01308580) is a randomized, open-label, multinational, phase III study comparing 20 mg/m2 and 25 mg/m2 Cbz for efficacy and tolerability. Pts with a life expectancy > 6 mos, ECOG PS ≤ 2, histologically/cytologically confirmed metastatic prostate adenocarcinoma resistant to hormone therapy and previously treated with a D-containing regimen are eligible. Pts are randomized 1:1 to receive Cbz 20 mg/m² or 25 mg/m² IV Q3W + P 10 mg PO QD, treated until disease progression, unacceptable toxicity or withdrawal of consent (max 10 cycles), and stratified according to ECOG PS, measurable disease (yes/no) and region. The primary endpoint is OS (non-inferiority design). Secondary endpoints include safety, progression-free survival (PCWG2 criteria), PSA and pain progression and response, tumor response in pts with measurable disease and health-related quality of life. Cbz PK and pharmacogenomics will be assessed in pt subgroups. Planned enrollment is 1,200 pts. Study start was in May 2011; as of Jan 2012, 270 pts had been enrolled. The first DMC meeting recommended continuing the study without change.

283 Background: Pelareorep (REOLYSIN) is a immuno-oncolytic virus (IOV) that induces an inflamed tumor phenotype secondary to viral infection of cancer cells. In combination with chemotherapy, it achieves 1 & 2 year-survival rates of 46% & 24% in MAP pts, respectively. Tumor analysis from pts showed reovirus protein replication, T-cell infiltration and upregulation of PD-L1. Similarly, the combination of pelareorep with anti-PD-1 antibody documented survival benefit in a pre-clinical model. We hypothesized that pelareorep in combination with chemo and pembrolizumab in pts with MAP would be clinically efficacious. Methods: A phase 1b study enrolled MAP pts who progressed after first line treatment. Pts received pelareorep (4.5 x 10 10TCID 50 IV, D1 & D2), plus pembrolizumab (2mg/kg IV, D8) plus either 1)5-FU (LV (200 mg/m2 /5-FU 200 mg /m2 IV bolus, 5-FU 1200mg/m2 continuous IV infusion D1) or 2) gemcitabine (1000 mg/m2 IV, D1), or 3) irinotecan (125 mg/m2 IV, D1) q3w, until disease progression/unacceptable toxicity. The primary endpoint was safety. Secondary objectives included tumor response & evaluation for reovirus replication/immune analysis. Results: 11 pts were enrolled with pelareorep, pembrolizumab and gem (n = 6), 5-FU (n = 3), or iri (n = 2). Most common grade 1 or 2 TEAEs include: fever (73%), headache (55%), chills (46%), dehydration (36%), fatigue (27%) and anemia (27%). One pt (gem arm), transient Gr 2 increased transaminases was reported on two occasions. Grade 3 or 4 TEAEs occurred in 8 pts (73%): abdominal pain, anemia, arthralgias, biliary obstruction, chills, DVT, diarrhea, fever, hyperglycemia, leukopenia, myalgias, nausea, neutropenia, pulmonary emboli, urinary tract infection and vomiting. Of the 5 efficacy evaluable pts, one had PR (13.8 m duration) and 2 SD (lasting 126 and 277 days). Eight died secondary to PD. On-treatment biopsy show reovirus infection in cancer cells and immune infiltrates. Conclusions: The combination therapy showed manageable safety profiles and antitumor activity in previously treated MAP pts. Further evaluation of anti-tumor activity of pelareorep and anti-PD-1 antibody ± chemotherapy combos is planned. Clinical trial information: NCT02620423.

9505 Background: We report updated safety and efficacy of DM4-conjugated anti-CEACAM5 ADC from the expansion part of the first-in-human study (NCT02187848; Gazzah A et al. J Clin Oncol. 2019;37:15, 9072) in 92 NSQ NSCLC pts. Methods: CEACAM5 expression was assessed by immunohistochemistry on archived tumor samples. Two cohorts of pts have been analyzed: moderate and high expressors, with CEACAM5 expression at ≥2+ intensity between ≥1% to < 50% and ≥50% of the tumor cell population, respectively. SAR408701 was administered at 100 mg/m2 IV every 2 weeks. Tumor assessments were done every 4 cycles (8 weeks). Primary endpoint was overall response rate (ORR). Results: As of January 2020, 92 pts were treated: 28 moderate and 64 high expressors, with median age 62.5 years (31–91; 42.4% of pts ≥65), 51.1% male, 71.7% ECOG PS ≥1; median of 3 prior treatments (1–10 lines) for advanced disease, including anti-tubulin agents (60.9%) and anti-PD1/PD-L1 (75%). In the moderate expressor cohort, 2 confirmed partial responses (PR) were observed (ORR 7.1%). In the high expressor cohort, 13 pts had confirmed PRs (ORR 20.3% [95% confidence interval 12.27%–31.71%]); 27 (42.2%) had stable disease; ORR of 17.8% was observed in 45 pts who had prior anti-PD1/PD-L1. Pts had a median of 7 (1–49) cycles; median relative dose intensity was 0.98. Six pts discontinued due to treatment-emergent adverse events (TEAEs). Most frequent TEAEs (all grades) were asthenia (38.0%), keratopathy/keratitis (38.0%), peripheral neuropathy (26.1%), dyspnea (23.9%), and diarrhea (22.8%). 31 pts had dose modification due to a TEAE, including dose reduction for keratopathy/keratitis in 10 pts. Hematological toxicity included leukopenia (14.4%), neutropenia (4.4%), and thrombocytopenia (13.3%). Grade ≥3 TEAEs occurred in 47.8% of pts and were assessed as drug-related in 15.2%. Conclusions: SAR408701 shows promising antitumor activity in heavily pretreated advanced NSQ NSCLC pts with high CEACAM5 expression. SAR408701 was well tolerated, with minimal hematological toxicity compared to conventional chemotherapy; keratopathy was reversible and manageable with dose modification. These data support the activity of SAR408701 in NSQ NSCLC CEACAM5 high expressors. A phase 3 trial evaluating the activity of CEACAM5-DM4 ADC monotherapy in comparison with docetaxel in NSQ NSCLC CEACAM5 high expressors after failure of standard first line chemotherapy and anti-PD1/PD-L1 is underway. Clinical trial information: NCT02187848 .

Abstract Pomalidomide is a new generation IMID, with a very good compliance, thanks to oral administration, which can be used also in heavily pretreated patients, in a domestic setting. In this retrospective observational trial, It has been evaluated efficacy and tolerance of pomalidomide plus dexamethasone (PD) as salvage regimen in heavily pretreated patients with relapsed and refractory MM (rrMM), whose prognosis is particularly severe. 57 patients (31 M/26 F), with rrMM, median age at diagnosis 69 years (r. 52-86), and median age at start of treatment 76 years (r.56-90) treated with several lines of treatments (median 7, r. 2-11), every refractory to all the drugs previously received (also Bortezomib, Thalidomide and Lenalidomide), received Pomalidomide-Dexamethasone (Pomalidomide 4 mg for 21 days, Dexamethasone 40 mg days 1,8,15,22, pegfilgrastim day +8) every 28 days, until progression. ISS was equally distributed, and cytogenetic at relapse was evaluable in 14 patients. All the patients had previously been treated with schedule containing bortezomib and IMIDs. 63% (36/57) had undergone at least to a single ASCT. All patients were relapsed and refractory to last therapies received before PD. Pomalidomide was well tolerated, with grade 3-4 transfusion-dependent anemia in 58% (33/57) of patients, 44% (23/57) grade 3-4 neutropenia (pegfilgrastim in primary prophylaxis was given, no hospitalization was required, no septic shocks were observed), 40% (23/57) grade 3-4 thrombocytopenia without hemorrhagic events and transfusion-dependence. No severe extra-hematologic toxicity was observed. According to IMWG, ORR1 (≥PR) was 47.3% (27/57: 5 CR, 11 VGPR, 7 PR, 4 MR), but, considering that we are evaluating a cohort of heavily pretreated patients, with poor prognosis, another parameter should be considered, ORR2 (≥SD), considering stable disease as a successful result in progressive MM. ORR2 was 77.1% (17 SD). These can be considered as impressive result in this subset of patients. Oral treatment gives a really good compliance, in frail and unfit patients, and response, when present, is always really fast (median time to response: 2 months (r.1-6)), median OS from diagnosis was 94 months (range 21-234), median OS from start of pomalidomide was 9 months (range 1-25). Nine patients have surprisingly achieved a notable response (3 VGPR, 4 PR, 2 MR) after failure of novel agents (i.e. Carfilzomib, Daratumumab and Pomalidomide). Pomalidomide-dexamethasone has shown significant efficacy and a very good compliance, thanks to oral administration, in a particularly severe setting of heavily pretreated patients, relapsed and refractory to all available therapeutic resources, also after failure of novel agents.
