Abstract

Abstract Objective To evaluate the pharmacokinetics of SHC014748M under the influence of different drugs . SHC014748M, a selective PI3Kδ inhibitor, has shown potential therapeutic value in patients with CLL/SLL and NHL in clinical studies. Methods This study employed a single-center, two-period, open-label, sequential-dose design. Key pharmacokinetic parameters were calculated using non-compartmental analysis using WinNonlin software (version 8.2). Results Coadministration of SHC014748M with CYP3A4/5 inhibitors or inducers significantly affected the maximum plasma concentration (C max ) , the area under the curve at the cutoff time point (AUC 0-t ), and the area under the curve extending to infinity (AUC 0-∞ ). This drug-drug interaction demonstrated statistically significant differences in pharmacokinetic parameters (90% confidence interval for the geometric mean ratio outside the 80.00% to 125.00% equivalence range). Conclusions Since SHC014748M is a substrate of CYP3A4/5 metabolizers, it may cause drug-drug interactions with CYP3A4/5 inhibitors and inducers during clinical use. In this study, SHC014748M capsules showed good tolerability. Trial registration Registration authority: China Drug Trials, TRN:CTR20201782, Registration date: August 27, 2020.

SHC014748M CYP3A4/5 Drug-drug interactions Tolerability Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Introduction SHC014748M 1 is a first-in-class small-molecule PI3Kδ-selective inhibitor independently developed by Nanjing Shenghe Pharmaceutical Co., Ltd. This molecule targets PI3Kδ through a non-ATP competitive mechanism and is designed for the treatment of patients with relapsed or refractory indolent B-cell non-Hodgkin lymphoma 2 (iNHL), including subtypes such as follicular lymphoma and marginal zone lymphoma.This highly specific interaction potently inhibits PI3Kδ kinase activity and effectively shuts down its downstream signaling cascade. By interfering with B-cell growth, maturation, and differentiation processes, SHC014748M suppresses the initiation and progression of B-cell malignancies 3 . In nonclinical and early clinical studies, SHC014748M has demonstrated favorable safety and efficacy 4 . In clinical treatment, patients taking multiple medications concurrently may experience drug-drug interactions 5 , also known as drug-drug interactions 6 (DDIs). This can alter the potency or effectiveness of the drugs in the body, potentially leading to more severe adverse reactions or compromising therapeutic efficacy. Preclinical studies have shown that SHC014748M is superior to idelalisib 7 in inhibiting CLL 8 and FL cell proliferation and blocking the pAkt signaling pathway 9 . SHC014748M can completely inhibit the increase in pAkt levels induced by anti-IgM stimulation at a lower concentration (100 nM), demonstrating significant clinical potential and making it suitable for in-depth anti-tumor clinical research 10 . Itraconazole 11 , known as a triazole antifungal, disrupts ergosterol formation in fungal cell membranes and serves as a powerful inhibitor of CYP3A4/5 and P-glycoprotein.Consequently, it can slow the metabolism of drugs that are substrates of CYP3A4/5, leading to increased systemic exposure.Rifampicin 12 , belonging to the rifamycin class of antibiotics, demonstrates significant efficacy against Mycobacterium tuberculosis and is also potent against many Gram-positive and Gram-negative bacteria, as well as some viruses. In clinical DDI studies, rifampicin is commonly employed as a strong CYP3A4/5 inducer 13 . The present investigation is a single-center, open-label drug–drug interaction study designed to evaluate the potential interactions between SHC014748M and itraconazole as well as rifampicin. Additionally, the trial will characterize the pharmacokinetic profile and tolerability of SHC014748M capsules in healthy volunteers, thereby providing critical dosing guidance for subsequent clinical studies 14 . Materials and methods Research material The study drug is SHC014748M capsules,as shown in Fig. 1 , batch number 201911191, with a dosage of 100 mg per capsule and an expiration date of October 2021. They require sealed storage. Itraconazole capsules, marketed as Sporanox®, batch number KBJ15H7, contain 100 mg per capsule and are expiration date of January 2022. They require sealed storage in a dry environment below 25°C. These capsules are manufactured by Xi'an Janssen Pharmaceutical Co. Ltd. Rifampicin capsules, batch number 2004011, contain 300 mg per capsule and are expiration date of March 2022. They require sealed storage in a dark, dry place. They are manufactured by Shenyang Hongqi Pharmaceutical Co., Ltd. All drugs were provided by Nanjing Shenghe Pharmaceutical Co., Ltd. Subject selection In this trial, 40 healthy male subjects were involved, split into 20 in the SHC014748M plus itraconazole group and 20 in the SHC014748M plus rifampicin group. Based on the results of previous safety pharmacology studies of SHC014748M capsules, safety and tolerability studies with single and multiple dose escalation, and studies of the effects of food on SHC014748M, this study enrolled healthy adult males. Nanjing Shenghe Pharmaceutical Co., Ltd. obtained clinical trial approval for SHC014748M capsules (100 mg) in February 2018 (approval numbers: 2018L02123 and 2018L02124) and commissioned the primary affiliated hospital of Bengbu Medical College to conduct the study. This clinical trial was approved by the Ethics Committee of the First Affiliated Hospital of Bengbu Medical College and was conducted in strict accordance with Good Manufacturing Practice (GCP) requirements and the principles of the Declaration of Helsinki. The investigators explained the relevant issues to the participants in detail before the trial, and all participants provided written informed consent. The trial is registered with www.chinadrugtrials.org.cn , number CTR20201782. In the drug interaction study with itraconazole, subject A011 withdrew from the study due to premature ventricular 15 contractions prior to dosing. Ultimately, 19 subjects completed the study. A total of 20 subjects participated in the drug interaction study with rifampicin. This trial did not employ randomization; subjects were assigned enrollment numbers and entered the trial based on the order in which they qualified after screening.As shown in Table 1 . Table 1 Summary of demographic baseline data Itraconazole (N = 19) Rifampicin (N = 20) Age (y) 26.6 ± 6.8 (18–40) 26.7 ± 5.0 (19–38) Height (cm) 171.6 ± 5.0 (164–184) 170.0 ± 5.8 (159–180) Weight (kg) 65.8 ± 5.6 (58–77) 65.6 ± 7.0 (52–79) BMI (kg/m²) 22.4 ± 1.8 (19.5–25.9) 22.7 ± 2.1 (19.4–25.9) Inclusion criteria The study enrolled healthy males aged 18 to 45 years, weighing between 50.0 and 80.0 kilograms, having a BMI ranging from 19.0 to 26.0 kg/m². All participants underwent a comprehensive health examination, including vital signs, electrocardiogram (ECG), blood tests, urine analysis, liver and kidney function, electrolyte levels, and blood glucose levels, all of which were within normal ranges or deemed clinically insignificant by the investigators. Exclusion criteria included: abnormal clinical manifestations, recent surgery affecting drug metabolism, difficulty swallowing or gastrointestinal history, recent use of liver enzyme inhibitors or inducers, positive antibodies for infectious diseases, allergy history, recent drug use or heavy smoking/drinking, recent use of other medications, inability to follow the study diet, or being deemed unsuitable for the trial by the investigator. These criteria were established to ensure the safety and scientific rigor of the study 16 . Administration method and blood sample collection This study enrolled 40 healthy male subjects. On the first day of the study, participants took 200 mg of SHC014748M capsules with 240 ml of warm water on an empty stomach after fasting for at least 8 hours. They were advised not to drink water for 1 hour before and 2 hours after taking the drug, and not to eat or drink for 4 hours after taking the drug to ensure that drug absorption and metabolism were not affected. In the drug-drug interaction study between SHC014748M and itraconazole, a wash-out period of three days (Days 1–3) was observed. From Day 4 to Day 9, itraconazole capsules were administered within 30 minutes after breakfast; on Day 10 the dose was taken under fasting conditions. A fixed 2-hour interval separated the intake of itraconazole and SHC014748M capsules. Subjects were required to abstain from water for 1 hour before and 2 hours after each study drug administration, and to remain fasted for 4 hours following the SHC014748M dose. Pharmacokinetic blood samples were collected at 1 hour pre-dose and at 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 48, and 72 hours post-dose on Days 1 and 10. To evaluate the potential drug–drug interaction between SHC014748M and rifampicin, subjects first underwent a 3-day wash-out period (Days 1–3). From Day 4 onward, participants received rifampicin 600 mg orally once daily. On Day 8, rifampicin was administered under fasted conditions, followed exactly 2 hours later by a single SHC014748M capsule. Water was prohibited 1 hour before and 2 hours after each dose; food intake was restricted for 4 hours following SHC014748M ingestion. Moreover, Pharmacokinetic blood samples were collected at 1 hour pre-dose and at 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 48, and 72 hours post-dose on Days 1 and 8 to characterize the plasma concentration–time profiles of both agents. For each sampling time point, extract roughly 3 ml of venous blood, put it in a K₂EDTA collection tube, and softly shake it 5 to 10 times to ensure immediate anticoagulation.Within 1.5 h of collection, samples were centrifuged at 4°C and 1500 g for 10 min. Two aliquots of 0.6–0.8 mL supernatant plasma were transferred into separate polypropylene tubes (primary and backup). The plasma samples were stored at -80°C until bioanalysis.

Table 3 Optimized mass parameters for SHC014748M and SHC014748M-d3(Internal standard) Analyte Q1 (Da) Q3 (Da) Dwell (msec) DP (V) EP (V) CE (V) CXP (V) Retention time(min) SHC014748M 417.2 282.2 110 40.0 10.0 31.0 15.0 0.83 SHC014748M-d3 422.0 287.0 110 40.0 10.0 32.0 15.0 0.83 Add 25.0 µL of the plasma sample to a 96-well deep-well plate, then introduce 25.0 µL of 500 ng/mL concentration internal standard solution to each sample and vortex for 3 minutes. Precipitate each sample by adding 400 µL of acetonitrile. Vortex for 5 minutes and centrifuge at 1700 g for 15 minutes at 4°C. Transfer 50.0 µL of the supernatant to another 96-well deep-well plate containing 950 µL of methanol and vortex for 5 minutes. Store the processed samples in the autosampler at 4°C until analysis. Kinetic analysis Spectral acquisition and peak integration for the analyte and internal standard were performed with the Analyst® 1.6.3 software (AB Sciex) facilitated the generation of calibration curves by plotting the y-axis as the peak-area ratio (analyte/internal standard) against the x-axis representing the nominal plasma concentration. Linear regression was carried out using a 1/x² weighted least-squares algorithm, yielding the equation y = ax + b. The resulting regression parameters were imported into Watson LIMS 7.5 for automated calculation and verification of sample concentrations. Drug-drug interactions between SHC014748M and itraconazole and rifampicin were evaluated according to the guidelines for drug interaction studies. Clinically significant drug interactions were considered absent when the 90% confidence intervals for the geometric mean ratios of Cmax, AUC0-t, and AUC0-∞ between SHC014748M combined with the interacting agent and SHC014748M by itself were entirely within the 80.00–125.00% range. The pharmacokinetic parameters C max , AUC 0 − t , and AUC 0−∞ were natural logarithm - transformed. A mixed-effects model was used, with subject as the random effect factor and co-administration/monotherapy as the fixed effect, to calculate the 90% confidence interval of the geometric mean ratio (co-administration/monotherapy) of the pharmacokinetic parameters. Result Safety evaluation results of SHC014748M and itraconazole In healthy male volunteers, SHC014748M 200 mg was administered once daily in the fasted state for 10 consecutive days; itraconazole 200 mg was added from Day 4 onward. No adverse events greater than Grade 3 or leading to discontinuation were reported, and the overall tolerability and safety profile remained favorable. Figures 2 and 3 display the mean plasma concentration–time curves for SHC014748M following a single 200 mg capsule, either administered alone or with 200 mg itraconazole. Descriptive pharmacokinetic parameters of SHC014748M following oral administration of 200 mg SHC014748M alone or with itraconazole 200 mg are summarized in Table 4 . Compared with SHC014748M administered as monotherapy, co-administration with itraconazole for 7 days produced no discernible shift in median T max (values remained identical), while C max and systemic exposure (AUC 0–t and AUC 0–∞ ) increased markedly, and apparent oral clearance (CL/F) trended downward 17 .

Data are shown as arithmetic mean ± standard deviation (SD) and Tmax as median (range). Confidence interval analysis of geometric mean ratios was performed for the main PK parameters of SHC014748M (C max , AUC 0 − t , and AUC 0−∞ ). The results showed that compared with SHC014748M capsules alone, the geometric mean ratios of SHC014748M C max , AUC 0 − t , and AUC 0−∞ after 7 consecutive days of itraconazole capsules combined with SHC014748M capsules (combination/single) were 146.3%, 215.2%, and 224.9%, respectively, all exceeding the 80.00%-125.00% no-effect margin 18 .For SHC014748M, the 90% confidence intervals of the geometric mean ratios for Cmax, AUC0-t, and AUC0-∞ after both combined and single administration were (119.89%-177.39%), (184.08%-252.11%), and (193.41%-262.30%), respectively. The above test results indicate that there is a drug-drug interaction between SHC014748M capsules and the mutagenic drug itraconazole capsules.As shown in Table 5 . Table 5 The 90% confidence interval (90%CI) of geometric mean ratios for the C max , AUC 0 − t and AUC 0−∞ of SHC014748M after a single dose of SHC014748M alone and in combination with itraconazole.

When used alone, SHC014748M caused 4 cases (elevated bilirubin, decreased neutrophil count, bradycardia); rifampin alone caused 4 cases (elevated bilirubin, elevated urinary leukocyte count, decreased lymphocyte count); and the combination of both drugs caused 4 cases (elevated triglycerides, elevated ALT/AST, elevated CRP, chest discomfort). Overall, the treatment was safe and well-tolerated. Figures 4 and 5 compare the average plasma concentration-time profiles of SHC014748M in healthy male participants after taking a single 200 mg SHC014748M capsule or alongside a 600 mg rifampin capsule. In healthy male subjects, the descriptive statistical results of SHC014748M's pharmacokinetic properties in plasma following the oral intake of 200 mg SHC014748M capsules on an empty stomach or in combination with 600 mg of rifampin capsules are presented in Table 6 . The pharmacokinetic parameter results indicate that, compared to monotherapy with SHC014748M capsules, co-administration with rifampin capsules after 5 days of continuous rifampin therapy resulted in a slight trend toward a shorter time to peak plasma concentration (T max ) for SHC014748M (the median T max under co-administration was 85.71% of that under monotherapy), the peak concentration (C max ) and exposure (AUC 0 − t , AUC 0−∞ ) showed a significant decrease, while the clearance rate (CL/F) showed a significant increase.

Data are shown as arithmetic mean ± standard deviation (SD) and Tmax as median (range). A geometric mean ratio confidence interval analysis was conducted for the primary PK parameters (C max , AUC 0 − t , and AUC 0−∞ ) of SHC014748M. The results showed that compared with taking SHC014748M capsules alone, co-administration of rifampicin capsules with SHC014748M capsules after 5 days of continuous rifampicin administration resulted in the geometric mean ratio values (combination therapy/monotherapy) for C max , AUC 0 − t , and AUC 0−∞ of SHC014748M were 52.24%, 22.84%, and 22.92%, respectively, all exceeding the 80.00% to 125.00% no-effect boundary range; The 90% confidence intervals for the geometric mean ratios of C max , AUC 0 − t , and AUC 0−∞ of SHC014748M after co-administration and monotherapy, calculated using the [1–2α] confidence interval method, were (42.59% to 64.08%), (20.25% to 25.76%), and (20.23% to 25.96%), respectively. The above experimental results indicate that there is a drug-drug interaction between SHC014748M capsules and the mutagenic drug rifampicin capsules.As shown in Table 7 .

AEs reported with continuous rifampicin therapy included increased blood bilirubin in three patients (15.0%, 3 episodes), positive urine leukocytes in two patients (10.0%, 2 episodes), and decreased lymphocyte count in one patient (5.0%, 1 episode). AEs reported with combined therapy included hypertriglyceridemia in one patient (5.0%, 1 episode), increased alanine aminotransferase in three patients (15.0%, 3 episodes), increased aspartate aminotransferase in two patients (10.0%, 2 episodes), increased C-reactive protein in one patient (5.0%, 1 episode), and chest discomfort in one patient (5.0%, 1 episode).As shown in Table 9 . Discussion SHC014748M is a highly selective PI3Kδ inhibitor. Similar drugs include the marketed Idelalisib, Duvelisib, and Copanlisib, as well as clinically tested drugs such as Zandelisib and Linperlisib 20 . Compared to these drugs, SHC014748M's greatest advantage lies in its higher selectivity (306-fold greater than PI3Kα for PI3Kδ and 69-fold greater than idelalisib), stronger in vitro activity, and improved efficacy in inducing tumor cell apoptosis. In early clinical trials, it has demonstrated no severe toxicity or adverse reactions with black box warnings, indicating better overall tolerability. In a drug interaction study between SHC014748M and itraconazole, co-administration of itraconazole (200 mg for 7 consecutive days) with SHC014748M did not significantly alter the peak time (T max ) of SHC014748M ( median values were consistent with monotherapy). However, peak concentration (C max ) and exposure (AUC 0 − t and AUC 0−∞ ) significantly increased, while clearance (CL/F) decreased. Furthermore, in a drug interaction study between SHC014748M and rifampicin, co-administration of rifampicin (600 mg for 5 consecutive days) with SHC014748M slightly shortened the peak time (T max ) of SHC014748M ( median value was 85.7% of monotherapy), significantly decreased peak concentration (C max ) and exposure (AUC 0 − t and AUC 0−∞ ), and significantly increased clearance (CL/F). Compared with SHC014748M alone, after 7 consecutive days of itraconazole administration 21 , the geometric mean ratios of SHC014748M C max , AUC 0 − t , and AUC 0−∞ (combination/single) were 145.3%, 215.2%, and 224.9%, respectively. Compared with SHC014748M alone, after 5 consecutive days of rifampicin administration, the geometric mean ratios of SHC014748M C max , AUC 0 − t , and AUC 0−∞ (combination/single) were 52.1%, 22.8%, and 23.0%, respectively. These values are outside the 80.00%–125.00% effect range. Therefore, significant drug-drug interactions exist between SHC014748M and the mutagenic agents itraconazole and rifampicin 22 .The cytochrome P450 3A4/5 enzyme (CYP3A4/5) inhibitor itraconazole has a moderate inhibitory effect 23 on the metabolic elimination of SHC014748M23, and the cytochrome P450 3A4/5 enzyme (CYP3A4/5) inducer 24 rifampicin has a moderate induction effect on the metabolic elimination of SHC014748M24 .Co-administration of itraconazole with SHC014748M for 7 consecutive days increased the human exposure to SHC014748M by approximately 2.2 times that of SHC014748M alone, an increase in exposure that may be clinically significant. Conversely, co-administration of rifampicin with SHC014748M for 5 consecutive days reduced the human exposure to approximately 23% of SHC014748M alone, a significant decrease in exposure that may also be clinically significant. In this study, SHC014748M capsules were generally well tolerated. Compared with either SHC014748M capsules or itraconazole capsules alone, combined use of the two drugs increased only the incidence of elevated alanine aminotransferase (ALT) and aspartate aminotransferase (AST), there was no significant rise in the overall occurrence of other adverse reactions or in the occurrence of specific adverse reactions. Furthermore, compared with either SHC014748M capsules or rifampicin capsules alone, the combined use of the two drugs did not increase the overall incidence of adverse reactions or the incidence of individual adverse reactions 25 . In summary, this study aimed to investigate significant drug-drug interactions between SHC014748M and both itraconazole and rifampicin. Itraconazole significantly increased SHC014748M exposure, while rifampicin significantly decreased SHC014748M exposure. These interactions may have important clinical implications, necessitating careful evaluation and dose adjustment when coadministered. Furthermore, SHC014748M capsules were well tolerated in this study, with no new safety concerns identified.
