NCT01614964 / Completed临床2期

Phase 2 Proof of Concept Study of a Candidate Aminoquinoline Antimalarial (AQ-13)

This is an initial efficacy study of a candidate antimalarial in human subjects with uncomplicated malaria caused by the most common and most important parasite in Africa (Plasmodium falciparum). This study will enroll 66 adult Malian males with uncomplicated P. falciparum malaria and randomize them to treatment with 1750 mg of the investigational drug (AQ-13) by mouth over 3 days or the current standard treatment, which is 2 doses of Coartem twice daily for 3 days. The hypothesis underlying this study is that AQ-13 will be similarly effective to Coartem for the treatment of uncomplicated P. falciparum malaria due to both chloroquine-susceptible and chloroquine-resistant parasites.

Food-Effect Bioavailability Study of AQ-13, a Candidate Antimalarial

The purpose of this study is to test the safety of a 2100 mg dose of AQ-13, a new candidate antimalarial active against drug-resistant P. falciparum infection, and to determine the effect of a standard fatty meal on the absorption of the drug from the gut and its blood levels.

NCT00323375 / Completed临床1期IIT

Randomized Controlled Trial of AQ-13, a Candidate Aminoquinoline Antimalarial, in Comparison With Chloroquine

The purpose of this protocol is to perform Phase 1 (safety/toxicity and pharmacokinetic) Studies of an investigational aminoquinoline antimalarial (AQ-13) in human subjects. The compound to be studied (AQ-13) is being examined because it is active in vitro against Plasmodium falciparum malaria parasites resistant to chloroquine (CQ) and other antimalarials (multi-resistant P. falciparum), and because its safety was similar to that of CQ in preclinical studies performed by SRI International (IND 55,670). AQ-13 was also selected for study because it is active in vivo in two monkey models of human malaria: 1] P. cynomolgi in the rhesus monkey (Macaca mulatta), a model of human infection with P. vivax, and 2] CQ-resistant P. falciparum in the squirrel monkey, a model of human infection with CQ-resistant P. falciparum.

AbstractBackgroundExpanding resistance to multiple antimalarials, including chloroquine, in South-East Asia (SEA) urges the development of new therapies. AQ-13, a chloroquine derivative, is a new drug candidate for treating malaria caused by Plasmodium falciparum.ObjectivesPossible cross-resistance between the 4-aminoquinolines amodiaquine, piperaquine and AQ-13 has not been assessed. In vitro parasite growth assays were used to characterize the susceptibility of multidrug-resistant and susceptible P. falciparum patient isolates to AQ-13.MethodsA [3H]hypoxanthine uptake assay and a 384-well high content imaging assay were used to assess efficacy of AQ-13 and desethyl-amodiaquine against 38 P. falciparum isolates.ResultsWe observed a strong cross-resistance between the chloroquine derivative amodiaquine and AQ-13 in Cambodian P. falciparum isolates (Pearson correlation coefficient of 0.8621, P < 0.0001).ConclusionsIn light of the poor efficacy of amodiaquine that we described recently in Cambodia, and its cross resistance with AQ-13, there is a significant risk that similar clinical efficacy of AQ-13-based combinations should be anticipated in areas of amodiaquine resistance.

Drug susceptibility of Plasmodium falciparum in eastern Uganda: a longitudinal phenotypic and genotypic study

BACKGROUNDTreatment and control of malaria depends on artemisinin-based combination therapies (ACTs) and is challenged by drug resistance, but thus far resistance to artemisinins and partner drugs has primarily occurred in southeast Asia. The aim of this study was to characterise antimalarial drug susceptibility of Plasmodium falciparum isolates from Tororo and Busia districts in Uganda.METHODSIn this prospective longitudinal study, P falciparum isolates were collected from patients aged 6 months or older presenting at the Tororo District Hospital (Tororo district, a site with relatively low malaria incidence) or Masafu General Hospital (Busia district, a high-incidence site) in eastern Uganda with clinical symptoms of malaria, a positive Giemsa-stained blood film for P falciparum, and no signs of severe disease. Ex-vivo susceptibilities to ten antimalarial drugs were measured using a 72-h microplate growth inhibition assay with SYBR Green detection. Relevant P falciparum genetic polymorphisms were characterised by molecular methods. We compared results with those from earlier studies in this region and searched for associations between drug susceptibility and parasite genotypes.FINDINGSFrom June 10, 2016, to July 29, 2019, 361 P falciparum isolates were collected in the Busia district and 79 in the Tororo district from 440 participants. Of 440 total isolates, 392 (89%) successfully grew in culture and showed excellent drug susceptibility for chloroquine (median half-maximal inhibitory concentration [IC₅₀] 20·0 nM [IQR 12·0-26·0]), monodesethylamodiaquine (7·1 nM [4·3-8·9]), pyronaridine (1·1 nM [0·7-2·3]), piperaquine (5·6 nM [3·3-8·6]), ferroquine (1·8 nM [1·5-3·3]), AQ-13 (24·0 nM [17·0-32·0]), lumefantrine (5·1 nM [3·2-7·7]), mefloquine (9·5 nM [6·6-13·0]), dihydroartemisinin (1·5 nM [1·0-2·0]), and atovaquone (0·3 nM [0·2-0·4]). Compared with results from our study in 2010-13, significant improvements in susceptibility were seen for chloroquine (median IC₅₀ 288·0 nM [IQR 122·0-607·0]; p<0·0001), monodesethylamodiaquine (76·0 nM [44·0-137]; p<0·0001), and piperaquine (21·0 nM [7·6-43·0]; p<0·0001), a small but significant decrease in susceptibility was seen for lumefantrine (3·0 nM [1·1-7·6]; p<0·0001), and no change in susceptibility was seen with dihydroartemisinin (1·3 nM [0·8-2·5]; p=0·64). Chloroquine resistance (IC₅₀>100 nM) was more common in isolates from the Tororo district (11 [15%] of 71), compared with those from the Busia district (12 [4%] of 320; p=0·0017). We showed significant increases between 2010-12 and 2016-19 in the prevalences of wild-type P falciparum multidrug resistance protein 1 (PfMDR1) Asn86Tyr from 60% (391 of 653) to 99% (418 of 422; p<0·0001), PfMDR1 Asp1246Tyr from 60% (390 of 650) to 90% (371 of 419; p<0·0001), and P falciparum chloroquine resistance transporter (PfCRT) Lys76Thr from 7% (44 of 675) to 87% (364 of 417; p<0·0001).INTERPRETATIONOur results show marked changes in P falciparum drug susceptibility phenotypes and genotypes in Uganda during the past decade. These results suggest that additional changes will be seen over time and continued surveillance of susceptibility to key ACT components is warranted.FUNDINGNational Institutes of Health and Medicines for Malaria Venture.

Review

作者: Kreidenweiss, Andrea ; Mengue, Juliana Boex ; Held, Jana

INTRODUCTIONAQ-13 is a drug candidate in development for the treatment of Plasmodium falciparum infections. The chemical structure is similar to chloroquine, a 4-aminoquinoline, with a shorter diaminoalkane side chain. Chloroquine has been the standard of care for P.falciparum malaria for more than 40 years, but the spread of resistant parasites in all malaria endemic regions has led to abandonment of the drug. The outstanding attribute of AQ-13 is its retrieval of activity against chloroquine-resistant P.falciparum. Areas covered: We review preclinical and clinical studies on AQ-13 and summarize findings on pharmacokinetic, safety, potency and efficacy. Expert opinion: Based on its properties invivo, the most likely future indication of AQ-13 could be case management of uncomplicated falciparum malaria - as a partner drug in a combination therapy. Several 4-aminoquinolines combined with a partner drug are on the market and in development. The outstanding properties of AQ-13 should be identified to direct further clinical development.
