The Kasabach-Merritt phenomenon (KMP) in kaposiform hemangioendothelioma (KHE) is characterized by life-threatening thrombocytopenia and consumptive coagulopathy. This study compared the efficacy and safety of sirolimus plus prednisolone versus sirolimus monotherapy as treatment strategies for KHE with KMP in the largest cohort to date. Participants were randomized to receive either sirolimus in combination with a short course of prednisolone or sirolimus monotherapy for at least 12 months. The primary outcome was defined as achievement of a durable platelet response (platelet count >100×109/L) at week 4. Participants completed efficacy assessments 2 years after the initial treatment. At week 4, a durable platelet response was achieved by 35 of 37 patients given sirolimus and prednisolone compared with 24 of 36 patients given sirolimus monotherapy (difference 27.9%; 95% CI, 10.0% to 44.7%). Compared with the sirolimus monotherapy group, the combination treatment group showed improvements in terms of measures of durable platelet responses at all points during the initial 3-week treatment period, median platelet counts during weeks 1 to 4, increased numbers of patients achieving fibrinogen stabilization at week 4, and objective lesion responses at month 12. Patients receiving combination therapy had fewer blood transfusions and a lower total incidence of disease sequelae than patients receiving sirolimus alone. The frequencies of total adverse events and grade 3-4 adverse events during treatment were similar in both groups. The responses seen in patients with KHE with KMP were profound and encouraging, suggesting that sirolimus plus prednisolone should be considered a valid treatment for KHE with KMP.

BACKGROUND: Treatment for TB is lengthy and toxic, and new regimens are needed.METHODS: Participants with pulmonary drug-susceptible TB (DS-TB) were randomised to receive: 200 mg pretomanid (Pa, PMD) daily, 400 mg moxifloxacin (M) and 1500 mg pyrazinamide (Z) for 6 months (6Pa200MZ) or 4 months (4Pa200MZ); 100 mg pretomanid daily for 4 months in the same combination (4Pa100MZ); or standard DS-TB treatment for 6 months. The primary outcome was treatment failure or relapse at 12 months post-randomisation. The non-inferiority margin for between-group differences was 12.0%. Recruitment was paused following three deaths and not resumed.RESULTS: Respectively 4/47 (8.5%), 11/57 (19.3%), 14/52 (26.9%) and 1/53 (1.9%) DS-TB outcomes were unfavourable in patients on 6Pa200MZ, 4Pa200MZ, 4Pa100MZ and controls. There was a 6.6% (95% CI –2.2% to 15.4%) difference per protocol and 9.9% (95%CI –4.1% to 23.9%) modified intention-to-treat difference in unfavourable responses between the control and 6Pa200MZ arms. Grade 3+ adverse events affected 68/203 (33.5%) receiving experimental regimens, and 19/68 (27.9%) on control. Ten of 203 (4.9%) participants on experimental arms and 2/68 (2.9%) controls died.CONCLUSION: PaMZ regimens did not achieve non-inferiority in this under-powered trial. An ongoing evaluation of PMD remains a priority.

3556 Background: Immune checkpoint blockade (ICB) has revolutionized patient outcome for the small mCRC subgroup with highly immunogenic disease. The majority of mCRC cases, however, are MSS without innate ICB susceptibility. In our ongoing METIMMOX study, we hypothesize that MSS mCRC can be transformed into an immunogenic condition by short-course oxaliplatin-based therapy (FLOX), enabling patients with unresectable, previously untreated metastases to obtain durable disease control when adding ICB therapy. Here we present the protocol-planned interim analysis. Methods: Eligibility criteria include infradiaphragmatic metastasis and C-reactive protein < 60 mg/L. At analysis 15 January 2021, 54 patients stratified according to primary tumor sidedness and mutational status and evaluable for the primary end point (progression-free survival; PFS) had been randomly assigned to a standard-of-care schedule of 8 FLOX cycles Q2W (control arm) or repeat sequential 2 FLOX cycles and 2 nivolumab cycles (240 mg Q2W) to a total of 8 cycles (experimental arm), for both arms before treatment break until disease progression and reintroduction of a new treatment sequence. Radiologic response assessment is every 8 weeks. Safety, tolerability, objective response rate, and duration of response are among secondary end points. Results: At median follow-up of 6.4 (range, 0.5-20) months, patients were well balanced between the treatment arms with regard to the predefined strata and single-organ or multiple-organ metastases. Median PFS for the entire groups of control and experimental arm patients was 5.6 (range, 0.5-15; n = 26) and 6.6 (range, 0.5-20; n = 28) months, respectively. The number of FLOX-related CTCAE grade 3 or higher adverse events, including 2 deaths after initial FLOX administration, was comparable in the two arms. Twelve immune-related grade 3-4 adverse events (no new safety signals) were recorded. In the experimental arm, 4 (16%) patients, all RAS/BRAF-mutant cases, had experienced complete response and 9 (32%) patients had ongoing objective response at 8 months. The control arm cases had 0 with complete response and 6 (23%) with ongoing objective response at 8 months, 1 of whom had proceeded to curative-intent liver surgery. Conclusions: MSS mCRC patients may hold the opportunity of ICB responsiveness evoked by short-course oxaliplatin-based chemotherapy. The search for predictive biomarkers of ICB responsiveness is ongoing in the specifically designed METIMMOX correlative study program. Clinical trial information: NCT03388190.

Abstract Abstract 4964 [Background and Purpose]: Azacitidine is a pyrimidine nucleoside analog of cytidine with hypomethylating and cytotoxic activity. Although azacitidine is currently approved for subcutaneous (SC) injection and intravenous(IV) administration for the treatment of myelodysplastic syndromes (MDS) in the US, there are limited data available on the treatment effects of IV versus SC administration. To compare the safety, pharmacokinetics (PK), and efficacy of IV with SC administration, a phase I/II study of azacitidine in Japanese patients with MDS was conducted. [Patients and Method]: Patients with RA, RA with ringed sideroblasts (RARS), RAEB, or RAEB-t defined by the French-American-British (FAB) classification were enrolled. RA and RARS must fulfill the additional criteria of significant marrow dysfunction (defined by cytopenias and/or transfusion requirements). Eligible patients were at least 20 years of age but younger than 80 and had a ECOG PS between 0 and 2. The patients were alternately assigned to receive azacitidine SC or IV (10-minutes) at 75 mg/m2/day for 7 days every 4 weeks for a minimum of 4 cycles. Patients who achieved a complete response (CR) received additional 3 cycles of azacitidine and were followed up without treatment. Subjects with a partial response (PR) or hematologic improvement (HI) received azacitidine until disease progression with a maximum of 18 cycles. Ten patients received azacitidine by both SC and IV administration on the different cycle and PK parameters were compared on day 1 of each cycle. The primary endpoints of this study were the safety, PK and HI according to the International Working Group (IWG 2006) criteria for MDS, respectively. [Results]: A total of 54 patients (10 in phase I portion and 44 in phase II portion) were enrolled between October 2007 and November 2008. Of these, 53 patients received at least one dose of azacitidine; 17 patients (32 %) were female; the median age was 65 years (range 35–77 years). FAB MDS subtypes were: RA (16/53, 30%); RARS (3/53, 6%); RAEB (20/53, 38%); RAEB-t (14/53, 26%). IPSS risk groups were: Low (0%); Int-1(23/53, 43%); Int-2(15/53, 28%); High(15/53, 28%). IPSS cytogenetic groups were: good (24/53, 45%); intermediate (13/53, 25%); poor (16/53, 30%). Fifty-one patients have completed the treatment protocol to date. The median number of treatment cycles was 7(range 1 – 18). Seven patients have completed 18 cycles of treatment. Two patients are continuing to receive treatment in their cycles 16 and 17. HI was observed in 53% (26/49) of patients. Median time to HI was 55 days (range 20–217). Of the 27 patients who were RBC transfusion dependent at baseline, 15 (56%) became transfusion independent. Hematologic response (CR, PR, or marrow CR) was achieved in 29% (15/51) of patients. Median time to hematologic response was 113 days (range 49–247). HI rate in SC and IV administration was 50 % (12/24) and 56 % (14/25), respectively. Hematologic response rate in SC and IV administration was 29% (7/24) and 30% (8/27), respectively. There were no significant differences between SC and IV administration of azacitidine for HI and hematologic response. The Cmax following IV administration was approximately 4-fold of that obtained following SC administration; however, the AUC(0-∞) following SC administration was 92.3 ± 15.8% compared to that of IV, indicating good bioavailability following SC administration. Overall, the PK profile was similar to that of the previously reported study. The most common grade 3 or 4 adverse events included neutropenia 80% (41/51), leukopenia 76% (39/51), hemoglobin decreased 71% (36/51) and thrombocytopenia 65% (33/51). Grade 3 or 4 non-hematologic adverse events which were observed more than 10% included pneumonia 12% (6/51) and hypophosphatemia 16%(8/51). There was no death during the study that occurred within 29 days of last dose of azacitidine. The safety profile did not differ significantly different between SC and IV administration with the exception of injection site reactions observed with SC administration, only. [Conclusions]: Azacitidine is generally well tolerated and demonstrated a beneficial effect in Japanese patients with MDS. The higher Cmax of IV dose was not translated into clinical outcomes; no difference was shown in both efficacy and safety profiles between SC and IV administration. Both IV and SC azacitidine are promising therapeutic options for Japanese patients with MDS. Disclosures: Kobayashi: Nippon Shinyaku Co., Ltd.: Research Funding.

Abstract Background Iron overloading is a common problem for adult with myelodysplastic syndrome (MDS), aplastic anemia (AA) or other chronic anemia. Deferasirox (DFX) has been proven as an effective therapy to chelating iron in these patients. Anyway, the safety of DFX is still a concern, and the information of safety profiles and efficacy are less understood in Taiwan. This study is planned primarily to collect long-term safety data of DFX treatment in iron-overloaded MDS, AA and other chronic anemia patients in Taiwan. Study Design This is an observational, single-arm, and multi-center study. Low-risk MDS or AA patients with transfusion-related iron overload, or patients with other anemia and serum ferritin more than 2000 ug/ml, were enrolled within the 18-month enrolling period if DFX is planned to be prescribed. Exposure of iron chelating agents other than DFX before trial initiation was allowed. The initial dose and subsequent adjustment of DFX were up to investigator¡¦s preference. All patients were followed for 3 years for adverse events (AEs) and disease outcomes. Results From 2009 to 2011, 79 patients were enrolled in this study, including 38 MDS, 23 AA and 18 other chronic anemias. Forty-seven cases (59.5%) were male, with mean age 64.3¡Ó17.8 y/o. Fifty-six (70.9%) subjects failed to complete the 3-year study period, but only 8 (10.1%) of the subjects withdrew DFX due to drug-related AEs. The mean DFX exposure dose during study was 17.7¡Ó4.02 mg/Kg/day. In contrast with those reported in literature, the most frequently reported drug-related AEs were rash (16, 20.3%), diarrhea (11, 14.0%), hypercreatinemia (8, 10.1%), pruritus (7, 8.9%), and so on (as in Table 1). When classified by organ systems, skin disorders were the frequently reported one (26, 32.9%), and followed by GI disorders (n=24, 30.4%). Grade 3-4 drug-related adverse events were rare (n=4, 5.1%). For all subjects, DFX could effectively decrease serum ferritin level from baseline (-985+/-2090 ng/ml (p=0.0154 vs. baseline) and -1710+/-2290 ng/ml (p=0.0424 vs. baseline) at 1 yr and 3 yr, respectively) (as in Figure 1). Notably, after DFX usage, 23 patients (32.4%) developed erythroid response according to IWG 2006 criteria; the mean hemoglobin could increase from 7.77+/-1.63 gm/dl (baseline) to 8.25+/-2.60 gm/dl (at 36 month, p=0.6172 vs. baseline), when the average transfusion amount was decreased from 2.3+/-1.4 units (baseline) to 1.6¡Ó0.5 units (at 36 months, p=0.0406 vs. baseline). (as in Figure 2). Ten patients (10/46, 21.7%) had platelet response. For the 38 MDS patients, DFX also could significantly lower serum ferritin level (-590+/-2490 ng/ml (p=0.4095 vs. baseline) and -1310+/-362 ng/ml (p=0.0013 vs. baseline) at 1 yr and 3 yr, respectively) but seemed to have a less extent than that in overall population. Similarly, 10 patients (21.7%) developed erythroid response after DFX use. The mean hemoglobin increment (from 7.67+/-1.67 gm/dl (baseline) to 8.55+/-3.45 gm/dl (at 36 month, p=0.6012 vs. baseline)) and the decrease of average transfusion amount (from 2.1+/-1.2 units (baseline) to 1.6+/-0.6 units (at 36 months, p=0.2943 vs. baseline) were not significant, probably due to low case number (as in Figure 2). Four (4/19, 21.1%) patients experienced platelet response. Conclusion This study showed that the profiles of AEs regarding DFX use for adult anemic patients with transfusion-related iron overload in Taiwan were significantly different from those reported in Western countries. The AE-related discontinuation rate was also relatively low. An expected efficacy to lowering serum ferritin by DFX, and a significantly degree of hematological improvement was noted, too. Table 1.

709 Background: Oxaliplatin is an important component of therapy for multiple gastrointestinal cancers. The incidence of hypersensitivity reaction (HSR) to oxaliplatin is approximately 10%, and about 3% are serious in nature (Grade 3 or 4). Data on management of hypersensitivity reactions is limited to small case series, with scarce information on the success rates of rechallenging patients who have previously reacted. Methods: We conducted a retrospective review of patients who had a documented hypersensitivity (HSR) to oxaliplatin utilizing our internal adverse event reporting system from January 1, 2007 until December 31, 2012. Results: 44 patients met inclusion criteria for this study. The majority had a grade 1 or 2 reaction (n = 36 or 81.82%). Seven patients had a grade 3 reaction and one patient experienced a grade 4 reaction. 29 patients were rechallenged with oxaliplatin during subsequent courses. Infusion durations were extended in 79% of cases, and additional premedications were administered in 90%. Two patients were treated with a desensitization protocol, which consisted of serial dilutions of oxaliplatin (given over approximately 8 hours) with a two-stage premedication regimen. With these measures, seventeen of the twenty-nine patients (66%) were able to receive 3 or more additional infusions, thirteen (45%) received 5 or more additional infusions, and 4 (14%) we able to receive 10 or more additional infusions. Conclusions: Our review of hypersensitivity reactions to oxaliplatin demonstrates that the majority of patients experience mild (Grade 1 or 2) reactions and are able to be successfully rechallenged in subsequent courses with modifications in the infusion rate and premedications. The use of these treatment strategies may prevent premature discontinuation of an important backbone drug for the treatment of gastrointestinal malignancies.

7032 Background: The prevalence of thrombocytopenia in MDS ranges from 40% to 65%, hemorrhagic complications range from 3% to 53%, and hemorrhagic deaths range from 14% to 24% (Kantarjian 2006). Platelet transfusion can lead to reactions, infection, and alloimmunization. AMG 531 is a thrombopoiesis-stimulating peptibody that increases platelet production. This phase 1/2 study evaluated the safety and efficacy of AMG 531 in thrombocytopenic MDS patients. Methods: A minimum of 5 subjects with low risk MDS (IPSS low or intermediate-1) and a platelet count of = 50×109/L were enrolled to receive 3 QW SC injections of AMG 531 in each of 4 sequential dose cohorts. After evaluation at week 4, subjects could continue AMG 531 in an optional treatment extension at their assigned dose or escalated to a responding dose. Erythroid growth factors were allowed, but no other active treatment. Results: 28 subjects (9 transfusion-dependent) have been enrolled to date. All subjects were evaluable for response and entered the extension; 17 continue treatment. Dose-limiting toxicity (DLT) was defined as a drug-related grade 3 or 4 adverse event (AE) or a platelet count ≥ 600×109/L. Two DLTs occurred, both due to elevated platelet counts. No treatment-related severe AEs occurred. There was 1 treatment-unrelated death. Overall, 17 subjects (61%) achieved a platelet response. Median baseline platelet count for responders was 25×109/L with a median peak platelet count of 130×109/L during the 4 week treatment period. Of the 18 subjects to date completing at least 12 weeks of treatment, 11 (48%) achieved a durable response of at least 8 consecutive weeks (revised IWG criteria, Cheson 2006). A total of 90 clinically significant thrombocytopenic events (39 bleeding, 51 transfusions) were observed over both treatment phases. There were 16 such events (12 bleeding, 4 transfusions) in 6 subjects with a durable response, 6 events (6 minor bleeds, 0 transfusions) during the durable response period. There were 74 events (27 bleeding, 47 transfusions) in 11 subjects without a durable response. Conclusions: These preliminary data suggest that bleeding and transfusion events can be reduced in thrombocytopenic low risk MDS patients who respond to AMG 531. [Table: see text]

336 Background: Immunotherapy is becoming established as an effective way of treating cancer. Immodulon Therapeutics is developing IMM-101, a heat-killed whole cell preparation of Mycobacterium obuense (NCTC 13365), which modulates systemic immune responses, as an adjunctive immunotherapy for pancreatic cancer. Methods: Patients with advanced pancreatic cancer and a WHO score of 0-2 were assigned randomly to receive IMM-101 (0.1 mL intradermal injection of 10 mg/mL) plus Gemcitabine (Gem) (1000 mg/m2for 3 consecutive weeks out of 4) or Gem alone. Per protocol, this could be continued to a 12-cycle maximum. The primary efficacy endpoint was overall survival (OS). Safety, tolerability and progression free survival (PFS) were also assessed. Results: A total of 110 patients were randomized, 75 to receive IMM-101 plus Gem and 35 Gem alone (ITT population). The PP population consisted of 63 and 35 patients, respectively. Conclusions were similar; here we report results of the PP analysis. Median OS was increased significantly by 29% to 7.2 months in the IMM-101 plus Gem group compared to 5.6 months in the Gem group (p=0.022; HR 0.60, 95% CI 0.38-0.94). Median PFS was increased significantly by 83% to 4.4 months in the IMM-101 plus Gem group compared to 2.4 months in the Gem group (p=0.003; HR 0.51, 95% CI 0.32-0.81). In the pre-defined sub-group of patients with metastatic disease (n=82), median OS was increased significantly by 70% to 7.5 months in the IMM-101 plus Gem group (n=54) compared to 4.4 months in the Gem group (n=28) (p=0.002; HR 0.46, 95% CI 0.28-0.76). A highly significant 91% increase in median PFS from 2.3 months in the Gem group to 4.4 months in the IMM-101 plus Gem group was observed (p<0.001; HR 0.40, 95% CI 0.24-0.66). IMM-101 was well tolerated. The only adverse events of NCI CTC ≥Grade 3 occurring more frequently in the IMM-101 group (absolute difference in frequency between the groups >5%) were asthenia 10.8% and abdominal pain 8.1% (both 2.9% in the Gem group). Conclusion: Clinically meaningful increases in OS and PFS were demonstrated with IMM-101. No additional burden of adverse events above those relating to chemotherapy or the underlying disease was observed. Clinical trial information: NCT01303172.

Abstract Abstract 3657 Background: Bendamustine and rituximab is proving to be a superior first-line option in the treatment of follicular lymphoma. 90Y-ibritumomab tiuxetan is an effective consolidation strategy after chemotherapy induction in patients with follicular lymphoma, but has never been sequentially combined with bendamustine. In this prospective, single-arm, open-label, multicenter phase II trial (Fol-BRITE), we aim to assess the response rate and safety of a short induction course of bendamustine and rituximab (B-R) for 4 cycles followed by consolidation with 90Y-ibritumumab tiuxetan (90Y-IT) for chemotherapy-naïve patients with follicular lymphoma. Methods: Subjects greater than the age of 18 with chemotherapy-naïve follicular lymphoma (grade 1–2 and 3a) requiring treatment are eligible for this study. Treatment consists of an initial dose of rituximab 375mg/m2, and then one week later, bendamustine 90mg/m2 on days 1 and 2, and rituximab 375mg/m2 on day 1 of a 28-day cycle. B-R is given for a total of 4 cycles. Patients are eligible for consolidation with 90Y-IT if they obtain at least a partial response (PR) after induction, with a platelet count over 150,000/mm3, and granulocyte counts 1,500/mm3 and a bone marrow infiltration of <25%. The primary endpoint of this study is the determination of the complete response (CR) rate after sequential therapy with B-R followed by 90Y-IT. Secondary endpoints are overall response (OR=CR+PR) rate after a short course of B-R (4 cycles) and conversion rate from PR after B-R to CR after 90Y-IT. Secondary endpoints also include progression-free survival and safety. An optimal Simon two-stage design is incorporated to allow an early futility look for complete responses. Results: Nineteen patients have started treatment in this study to date, 13 have completed B-R and 7 have received 90Y-IT. Response rates after 4 cycles of B-R: Thirteen patients have completed 4 cycles of B-R and 13 are evaluable for response. Seven of 13 evaluable patients have had a CR (53.8%) and 5 of 13 patients have had a PR (38.5%) after 4 cycles of B-R for an OR rate of 92.3%. Response rates after B-R followed by 90Y-IT: Seven of 13 B-R-treated patients have received 90Y-IT and are evaluable for the primary endpoint of complete response. Of the 13 B-R treated patients, one patient in CR was unable to receive 90Y-IT due to thrombocytopenia, and one other patient was not eligible to receive 90Y-IT due to achievement of stable disease only. Six of the 7 evaluable patients are in CR (85.7%) and one patient remains in a PR (14.3%) after consolidation with 90Y-IT. Of the 3 subjects who attained a PR after B-R, 2 (66.7%) converted to a CR after 90Y-IT, with one late conversion 16 months after 90Y-IT. Hematologic toxicities after B-R included grade 4 neutropenia (1), grade 3–4 lymphopenia (3), and no grade 3–4 thrombocytopenia, out of 13 patients evaluable. Hematologic toxicities after 90Y-IT were acceptable, including grade 3–4 neutropenia (6), grade 3–4 lymphopenia (5), and grade 3–4 thrombocytopenia (4), out of 7 patients evaluable for toxicity. There have been no incidences of neutropenic fever. All patients have recovered their blood counts 7 to 12 weeks after Y90-IT. One out of 19 patients treated in this study has developed chronic myelogenous leukemia, occurring 11 months after treatment with Y90-IT. Conclusions: In this early pre-planned analysis of the first-stage of an optimal Simon two-stage design, we report this combination of therapy is both effective and safe. The CR rate of patients completing all study therapy is 85.7%, and well exceeds the limits required to continue this trial with an accrual goal of 39 subjects. Sequential treatment with B-R followed by Y90-IT is a promising option for the treatment of follicular lymphoma.

Abstract Previous observational studies suggest that rituximab may be useful in the treatment of primary immune thrombocytopenia (ITP). This randomized trial investigated rituximab efficacy in previously untreated adult ITP patients with a platelet count of 20 × 109/L or less. One hundred three patients were randomly assigned to receive 40 mg/d dexamethasone for 4 days with or without 375 mg/m2 rituximab weekly for 4 weeks. Patients who were refractory to dexamethasone alone received salvage therapy with dexamethasone plus rituximab. Sustained response (ie, platelet count ≥ 50 × 109/L at month 6 after treatment initiation), evaluable in 101 patients, was greater in patients treated with dexamethasone plus rituximab (n = 49) than in those treated with dexamethasone alone (n = 52; 63% vs 36%, P = .004, 95% confidence interval [95% CI], 0.079-0.455). Patients in the experimental arm showed increased incidences of grade 3 to 4 adverse events (10% vs 2%, P = .082, 95% CI, −0.010 to 0.175), but incidences of serious adverse events were similar in both arms (6% vs 2%, P = .284, 95% CI, −0.035 to 0.119). Dexamethasone plus rituximab was an effective salvage therapy in 56% of patients refractory to dexamethasone. The combination of dexamethasone and rituximab improved platelet counts compared with dexamethasone alone. Thus, combination therapy may represent an effective treatment option before splenectomy. This study is registered at http://clinicaltrials.gov as NCT00770562.

1075 Background: No standard treatment exists for triple negative breast cancer (TNBC) with failure of multi-line therapies. Apatinib is a small-molecule tyrosine kinase inhibitor that has promising anti-angiogenesis and antitumor activity for TNBC. We aimed to evaluate the safety and efficacy of adding apatinib to chemotherapy in patients with metastatic TNBC with failed first/second-line treatment. Methods: This randomized, open-label, phase 2 trial recruited patients with advanced TNBC who failed to receive first or second-line treatment. A total of 66 patients were randomly assigned, in a 1:1 ratio, to receive vinorelbine 25 mg/m2 (days 1, 8, 15) or vinorelbine 20 mg/m2 (days 7, 14, 21) with apatinib (250 mg once daily, days 1-5, 8-12, 15-19, if tolerable, the second cycle started with 500 mg per day) in 28-day cycles. The efficacy was evaluated every two treatment cycles (8 weeks ± 3 days). According to the RECIST criterion, patients with CR, PR and SD continued treatment until disease progression or unacceptable toxicity or withdrawal of consent. The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), overall response rate (ORR) and safety. Results: Between Sep 14, 2017 and Dec 08, 2020, 66 patients underwent randomization. Median follow-up was 21.3 months. 33 received apatinib plus vinorelbine and 32 received vinorelbine (1 was withdrawal of consent). Median PFS was significantly longer in the apatinib plus vinorelbine group than in the vinorelbine group (3.8 months vs. 1.9 months; hazard ratio for disease progression or death, 1.76; 95% confidence interval [CI], 1.02 to 3.05; P= 0.039). Median OS was 14.6 months with apatinib plus vinorelbine and 14.1 months with vinorelbine (HR,1.34; 95% CI, 0.60 to 3.00; P= 0.469). The ORR was 48.5% in the apatinib plus vinorelbine group and 31.3% in the vinorelbine group ( P= 0.156). The most common treatment-related hematologic grade 3–4 adverse events in those treated with apatinib plus vinorelbine versus vinorelbine, respectively, were leukopenia (42.4% vs. 34.4%), granulocytopenia (57.6% vs. 28.1%), anemia (9.1% vs. 12.5%) and thrombocytopenia (3.1% vs. 3.0%). The most frequent grade 3 nonhematologic toxicities were hand–foot syndrome (21%), proteinuria (9%), hypertension (9%) and increased ALT (9%) and which only occurred in apatinib plus vinorelbine group. No treatment-related nonhematologic grade 4 adverse events or treatment-related deaths were observed. Conclusions: Collectively, among patients with advanced TNBC with failed first/second-line treatment, apatinib plus vinorelbine show a promising benefit in PFS compared to vinorelbine monotherapy. Apatinib plus vinorelbine regimen shows promising efficacy and manageable toxicity, which might be a previously unappreciated therapeutic option for advanced TNBC.
