The epidermal growth factor receptor (EGFR) signaling is aberrantly overexpressed in many solid malignancies, making it an important target for anti-cancer biologic agents. Among them, epidermal growth factor receptor inhibitors (EGFRIs), which have been widely used in clinical practice, include anti-EGFR monoclonal antibodies and tyrosine kinase inhibitors. A proportion of patients treated with EGFRIs develop specific, dose-dependent skin toxicity such as papulopustular rash, paronychia, xerosis and itch. These side effects can cause physical and psychosocial discomfort that may result in dose reduction, discontinuance, or replacement of the current EGFRIs treatment. Correct diagnosis and treatment of these skin and mucosal adverse effects associated with EGFRIs is of great significance for the tertiary prevention of malignant tumors. A review on EGFRI-related mucocutaneous adverse reactions is presented here, focusing on the pathogenesis, the various clinical manifestations, the strategies for prevention and treatment of these conditions.

OBJECTIVEThis study aims to evaluate the efficacy and safety of crizotinib for advanced ALK-positive non-small cell lung cancer (NSCLC) patients.

METHODSTwenty-eight patients with advanced ALK-positive NSCLC were given orally crizotinib 250 mg b. i.d., and were followed up to evaluate the therapeutic efficacy and safety.

RESULTSAmong the 28 patients, the objective response rate (ORR) was 71.4% (20/28) and disease control rate (DCR) was 92.9% (26/28). Three patients achieved complete response. Seventeen patients had partial response. The most common drug-related adverse events were mild flickering vision and gastrointestinal reaction. Eleven patients experienced flickering vision. Nine patients had nausea and vomiting. Eight patients had diarrhea. They were all reversible and of grade I or II. Only one patient had grade III myelosuppression. Among the 28 patients, 16 cases were disease-free and 12 cases had progressive disease, with a progression-free survival of 8.2 months.

CONCLUSIONSCrizotinib is effective and tolerable in the treatment of advanced ALK-positive NSLCC. However, its long-term treatment efficacy requires to be further studied.

BACKGROUND/AIMS: The aim of this study was to assess the efficacy and safety of tofacitinib (5 and 10 mg twice daily) in patients with active rheumatoid arthritis (RA). METHODS: A systematic review of randomized controlled trials (RCTs) that examined the efficacy and safety of tofacitinib in patients with active RA was performed using the Medline, Embase, and Cochrane Controlled Trials Register databases as well as manual searches. RESULTS: Five RCTs, including three phase-II and two phase-III trials involving 1,590 patients, met the inclusion criteria. The three phase-II RCTs included 452 patients with RA (144 patients randomized to 5 mg of tofacitinib twice daily, 156 patients randomized to 10 mg of tofacitinib twice daily, and 152 patients randomized to placebo) who were included in this meta-analysis. The American College of Rheumatology 20% response rate was significantly higher in the tofacitinib 5- and 10-mg groups than in the control group (relative risk [RR], 2.445; 95% confidence interval [CI], 1.229 to 4.861; p = 0.011; and RR, 2.597; 95% CI, 1.514 to 4.455; p = 0.001, respectively). The safety outcomes did not differ between the tofacitinib 5- and 10-mg groups and placebo groups with the exception of infection in the tofacitinib 10-mg group (RR, 2.133; 95% CI, 1.268 to 3.590; p = 0.004). The results of two phase-III trials (1,123 patients) confirmed the findings in the phase-II studies. CONCLUSIONS: Tofacitinib at dosages of 5 and 10 mg twice daily was found to be effective in patients with active RA that inadequately responded to methotrexate or disease-modifying antirheumatic drugs, and showed a manageable safety profile.

BACKGROUNDFamitinib is a novel and potent multitargeting receptor tyrosine kinase inhibitor. The phase I clinical study showed that famitinib was well tolerated and had a broad anti-tumor spectrum. The purpose of this study was to examine the efficacy and safety of famitinib for the treatment of metastatic renal cell carcinoma (mRCC).

METHODSThe data of famitinib in treating patients with mRCC from the single-center phases I and II clinical trials were analyzed. Famitinib was administered orally at the dose of 13-30 mg once daily until tumor progression, occurrence of intolerable adverse reactions or withdrawal of the informed consent.

RESULTSA total of 24 patients with mRCC were treated including 17 patients at a dose of 25 mg once daily, 4 patients at a dose of 27 mg and 1 patient each at a dose of 13 mg, 20 mg and 30 mg, respectively. Twelve (50.0%) patients achieved partial response (PR) and 9 patients achieved stable disease (SD). Progressive disease was found in 3 (12.5%) patients. The disease control rate was 87.5%. The median follow-up time was 17.6 months; the median progression free survival (PFS) was 10.7 (95% CI 7.0-14.4) months; and the estimated median overall survival (OS) time was 33.0 (95% CI 8.7-57.3) months. The adverse drug reactions mainly included hypertension (54.1%), hand-foot skin reactions (45.8%), diarrhea (33.3%), mucositis (29.2%), neutropenia (45.8%), thrombocytopenia (29.2%), hyperlipidemia (41.7%) and proteinuria (41.7%). The incidence rate of grades 3 and 4 adverse events was low, mainly including hypertension 12.5%, hand-foot skin reactions 4.2%, neutropenia 4.2%, thrombocytopenia 4.2%, hyperlipidemia 4.2% and proteinuria 12.5%.

CONCLUSIONSFamitinib has significant anti-tumor activity in mRCC. The common adverse reactions are generally manageable.

Background: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This study assessed the efficacy and safety of tofacitinib in Chinese patients with RA enrolled in Phase 3 and long-term extension (LTE) studies. Methods: ORAL Sync was a 1-year, randomized, placebo-controlled, Phase 3 trial. Patients received tofacitinib 5 or 10 mg twice daily (BID) or placebo advanced to tofacitinib 5 or 10 mg BID at 3 or 6 months. All patients remained on ≥1 background conventional synthetic disease-modifying antirheumatic drug. ORAL Sequel is an open-label LTE study (data-cut: March 2015; data collection and analyses were ongoing, and study database was not locked at the time of analysis; study was closed in 2017). Efficacy outcomes: American College of Rheumatology (ACR) 20/50/70 response rates and Disease Activity Score in 28 joints using erythrocyte sedimentation rate (DAS28-4 [ESR]). Patient- and physician-reported outcomes: Health Assessment Questionnaire-Disability Index (HAQ-DI), Patient and Physician Global Assessment of Arthritis, and pain (visual analog scale). Safety was assessed throughout. Results: ORAL Sync included 218 patients; 192 were subsequently enrolled into ORAL Sequel. In ORAL Sync, more patients achieved ACR20 (tofacitinib 5 mg BID, 67.4%; 10 mg BID, 70.6%; placebo, 34.1%) and DAS28-4 (ESR) <2.6 (tofacitinib 5 mg BID, 7.1%; 10 mg BID, 13.1%; placebo, 2.3%) with tofacitinib versus placebo at Month 6. Mean changes from baseline in HAQ-DI were greater with tofacitinib versus placebo at Month 6. In ORAL Sequel, efficacy was consistent to Month 48. Incidence rates for adverse events of special interest in tofacitinib-treated patients were similar to the global population. Conclusions: Tofacitinib significantly reduced signs/symptoms and improved physical function and quality of life in Chinese patients with moderate-to-severely active RA up to Month 48. The safety profile was consistent with the global population. Clinical Trial Identifier NCT00856544 and NCT00413699.

OBJECTIVETo study the efficacy and safety of Chinese Childhood Leukemia Group ALL 2008 (CCLG-ALL2008) protocol combined with tyrosine kinase inhibitor (TKI, imatinib) for the treatment of Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) in children.

METHODSThe clinical data of 53 patients aged less than 15 years when first diagnosed with Ph+ ALL between October 2008 and December 2013 were retrospectively analyzed. The patients were assigned to two groups: HR (n=26) and HR+TKI (n=27). The HR group was treated with CCLG-ALL2008 protocol (for high-risk patients). The HR+TKI group was treated with imatinib in combination with CCLG-ALL2008 protocol (for high-risk patients).

RESULTSThe complete remission rate and chemotherapy induction-related mortality rate in the TKI+HR and HR groups were 100% vs 75% and 0 vs 15%, respectively. The 3-year event-free survival (EFS) rate in the HR group was (6±5)%; the 5-year EFS rate of the TKI+HR group was (52±11)%. Compared with the HR group, the TKI+HR group had no increase in the toxic responses to chemotherapy and had a decrease in the infection rate during the induction period.

CONCLUSIONSApplication of imatinib significantly improves the clinical efficacy in children with Ph+ ALL and has good safety.

OBJECTIVEEpidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) such as gefitinib and erlotinib are used as standard 2(nd)/3(rd) line therapy in previously treated advanced non-small cell lung cancer (NSCLC). However, the optimal treatment for patients who experienced disease progression after chemotherapy and EGFR-TKI is unclear. The aim of this study was to explore the efficacy and safety of a salvage chemotherapy in advanced NSCLC patients who failed the previous treatment of platinum-based chemotherapy and EGFR-TKI.

METHODSClinicopathological data of 55 cases of advanced NSCLC patients who failure of first-line platinum-based chemotherapy and subsequent treatment with TKI were collected and analyzed. The patients were of PS = 0-2, and with normal vital organ function. Patients received salvage chemotherapy until disease progression or unacceptable toxicity or the patient refused to continue receiving treatment. A chart review assessed the key outcomes including the objective response rate (ORR), disease control rate (DCR) and progression-free survival (PFS).

RESULTSFifty-five patients were enrolled in this study from march 2007 to october 2009. The median age of patients was 55 years (range: 34 - 72), 60.0% were males, PS 0-1 patients were 65.5%, stage IV patients were 100%; 34.5% had a TKI treatment duration ≥ 6 months. Twenty-four patients received pemetrexed as salvage chemotherapy, 21 received docetaxal and 10 had other chemotherapy. All patients were evaluable for efficacy. Among them, 7 (12.7%) patients achieved PR, 21 (38.2%) patients SD, and 27 (49.1%) patients PD, with ORR of 12.7% and DCR of 50.9%. The median follow-up duration was 5.5 months, and the median PFS was 2.0 months. The ORR and PFS were not significantly related with gender, PS and chemotherapy regimens (all P > 0.05), but patients with EGFR-TKI treatment ≥ 6 months achieved a significantly better ORR and DCR than those < 6 months (ORR: 21.1% vs. 8.3%, P = 0.012; DCR: 73.3% vs. 38.9%, P = 0.017), mPFS was significant longer in the patients received ≥ 6 months of EGFR-TKI (4.5 vs. 2.0 months, P = 0.008). The toxicity was acceptable and there were no treatment-related deaths.

CONCLUSIONAdvanced NSCLC patients failed with the previous treatment of first-line platinum-based chemotherapy and EGFR-TKI may benefit from salvage chemotherapy, especially in patients who received ≥ 6 months of EGFR-TKI. The toxicity of the salvage chemotherapy is acceptable.

Osimertinib-induced interstitial lung disease (ILD) is an uncommon, but fatal pulmonary toxicity in some patients. We report a case of a 64-year-old male with stage IV adeno-non-small cell lung cancer (NSCLC) harboring an exon 19 deletion in the epidermal growth factor receptor (EGFR) treated with osimertinib 80 mg/d for first-line targeted therapy. On day 60 after initiating treatment of osimertinib, the patient developed ILD. Osimertinib was discontinued immediately and oral prednisone 60 mg/d was initiated, ILD improved within 13 d. After balancing the risk and benefit, osimertinib was restarted concurrently with prednisone. The patient showed neither disease progression nor a recurrence of ILD for more than 16 months. Based on our case and literature review, retreatment with osimertinib under steroid coverage could be considered as an effective treatment option after careful risk-benefit assessment for patients with EGFR-mutant NSCLC.
