Study summary

This study aimed to determine the efficacy, safety and tolerability of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in pediatric patients (6 months to \< 18 years of age) with uncomplicated P. falciparum malaria. There is an unmet medical need for anti-malarial treatment with a new mechanism of action to reduce the probability of developing resistance.

Read the detailed description

This Phase 2 study aimed to evaluate the efficacy, safety and tolerability of the investigational drug KAF156 and a Solid Dispersion Formulation of lumefantrine (LUM-SDF) when administered in combination in pediatric patients 6 months to \< 18 years of age with uncomplicated Plasmodium falciparum malaria. In addition, pharmacokinetics (PK) of the drug combination was also evaluated.

There were three age-descending cohorts in the study: Run-in Cohort (12 years to \< 18 years), Cohort 1 (2 years to \< 12 years) and Cohort 2 (6 months to \< 2 years). The rationale for separated cohorts 1 and 2 was to allow enrolment of the youngest patients (cohort 2) after safety and exposure review of older patients in cohort 1. Given the age-independent symptoms of acute malaria, and to increase statistical power, for all outcomes measures the cohorts 1 and 2 were pooled (cohort 1/2). This new study first explored the effect of food on lumefantrine and KAF156 pharmacokinetics (PK) in patients 12 to \< 18 years old with malaria caused by P. falciparum. Based on the data from the Run-in Cohort, recommendation on dose, dosing regimen, dosage administration (with food) and duration were provided before younger patients in Cohorts 1 and 2 were dosed with KAF156/LUM-SDF. Then, efficacy, safety, tolerability and PK of the combination of KAF156/LUM-SDF in comparison with Coartem®(Artemether/Lumefantrine) were evaluated in younger patients, in pooled Cohort 1/2.

Terms in these criteria, in plain language(16)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Polymerase Chain Reaction (PCR)-Corrected Adequate Clinical and Parasitological Response (ACPR) - Cohorts 1 and 2 Pooled

    PCR-corrected ACPR, defined as the absence of parasitemia(PS), was evaluated on Day29. Microscopic species identification was confirmed and determined by PCR genotyping methods to establish malaria recrudescence/reinfection.A participant was considered as PCR corrected ACPR at Day29 if the participant did not meet any of the criteria of early treatment failure (up to Day4), late clinical failure(Day5 to Day29) or late parasitological failure(Day8 to Day29), and had absence of PS on Day29 irrespective of axillary temperature unless the presence of PS after 7days(Day8 or later) was due to reinfection based on PCR genotyping.A presence of PS after 7days of treatment initiation was considered as a reinfection only if the PS was clear before Day8 and none of the parasite strain(s) detected on Day8 or later match with the parasite strain at baseline based on PCR genotyping.Given the age-independent symptoms of acute malaria, and to increase statistical power,the cohorts 1 and 2 were pooled.

    Time frame: Day 29

Secondary outcomes

  1. PCR-corrected and Uncorrected Adequate Clinical and Parasitological Response (ACPR)

    PCR-corrected ACPR, defined as the absence of parasitemia, was evaluated. Microscopic species identification was confirmed and determined by polymerase chain reaction (PCR) genotyping methods to establish malaria recrudescence/reinfection. A participant was considered as PCR-corrected ACPR if the participant did not meet any of the criteria of early treatment failure, late clinical failure or late parasitological failure and had absence of parasitemia on Days 15, 29 or 43 irrespective of axillary temperature unless the presence of parasitemia after 7 days was due to reinfection based on PCR. A presence of parasitemia after 7 days of treatment initiation was considered as a reinfection only if the parasitemia was clear before Day 8 and none of the parasite strain(s) detected on Day 8 or later matched with the parasite strain at baseline based on PCR. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: Corrected ACPR: Day 15, Day 43; Uncorrected ACPR: Day 15, Day 29 and Day 43

  2. PCR-corrected Adequate Clinical and Parasitological Response (ACPR) - Run-in Cohort

    PCR-corrected ACPR, defined as the absence of parasitemia, was evaluated on Day 29. Microscopic species identification was confirmed and determined by polymerase chain reaction (PCR) genotyping methods to establish malaria recrudescence/reinfection. A participant was considered as PCR corrected ACPR at Day 29 if the participant did not meet any of the criteria of early treatment failure (ETF) (up to Day 4), late clinical failure (LCF) (Day 5 to Day 29) or late parasitological failure (LPF) (Day 8 to Day 29), and had absence of parasitaemia on Day 29 irrespective of axillary temperature unless the presence of parasitaemia after 7 days (Day 8 or later) was due to reinfection based on PCR genotyping. A presence of parasitaemia after 7 days of treatment initiation was considered as a reinfection only if the parasitaemia was clear before Day 8 and none of the parasite strain(s) detected on Day 8 or later match with the parasite strain at baseline based on PCR genotyping.

    Time frame: Day 29

  3. Parasite Clearance Time (PCT)

    PCT is defined as time from the first dose until the first total and continued disappearance of asexual parasite forms which remained at least a further 48 hours. PCT is based on uncorrected parasite counts. PCT was calculated using the Kaplan-Meier method. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: up to 43 days

  4. Fever Clearance Times (FCT)

    FCT is defined as time from the first dose until the first time the axillary body temperature decreased below and remained below 37.5°C axillary or 38.0°C oral/tympanic/rectal for at least a further 24 hours. FCT was calculated using the Kaplan-Meier method. Participants who received any antimalarial medication (including rescue medication) before fever clearance are censored at the first use of antimalarial medication. Participants without fever clearance are censored at the time of last fever assessment. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: up to 43 days

  5. Percentage Early Treatment Failure (ETF)

    Participants were defined as early treatment failures (ETFs) if they developed danger signs or severe malaria on Day 2, Day 3, or Day 4 in the presence of parasitemia, parasitemia on Day 3 with a count higher than the Day 1 count irrespective of axillary temperature, parasitemia on Day 4 with axillary temperature ≥ 37.5°C, or parasitemia on Day 4 with a count equal to or more than 25% of the count on Day 1. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: From Day 1 to Day 4

  6. Percentage Late Clinical Failure (LCF)

    Participants were defined as late clinical failures (LCFs) if they developed danger signs or severe malaria on any day from Day 5 to Day 43 in the presence of parasitemia without previously meeting any of the criteria of ETF, or if they had parasitemia and an axillary temperature of ≥ 37.5°C on any day from Day 5 to Day 43 without previously meeting any of the criteria of ETF. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: Day 5 to Day 43

  7. Percentage Late Parasitological Failure (LPF)

    Participants were defined as late parasitological failures (LPFs) if they had parasitemia on any day from Day 8 to Day 43 and an axillary temperature \< 37.5°C without previously meeting any of the criteria of ETF or LCF. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: Day 8 to Day 43

  8. Number of Participants With Recrudescence Events

    Recrudescence is defined as appearance of asexual parasites after clearance of initial infection with a genotype identical to that of parasites present at baseline. Recrudescence had to be confirmed by PCR analysis. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: Day 15, Day 29 and Day 43

  9. Number of Participants With New Infections Events

    New infection is defined as appearance of asexual parasites after clearance of initial infection with a genotype different from those parasites present at baseline. New infection had to be confirmed by PCR analysis. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: Day 15, Day 29 and Day 43

  10. Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Number of participants with treatment emergent adverse events (any AE regardless of seriousness), and SAEs. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).

    Time frame: Adverse events were reported from first dose of study treatment until end of study treatment up to a maximum duration of approximately 43 days.

  11. KAF156 and Lumefantrine (LUM) Cmax

    Cmax is the maximum observed plasma concentration following drug administration. PK parameters are calculated from plasma concentration-time data using non-compartmental methods. Analyte KAF156 is not applicable for Artemether80mg/LUM480mg arm.

    Time frame: Run-in Cohort:Pre-dose,1,3,4,5,6,8,24,25,27,28,29,30,32,48,72,168 hours; Cohort 1 and 2 KAF400mg/LUM480mg-QDx3 6-12 years: 3,6,24,48,51,54,72,168 hours; 6 months -<6 years:24,48,51,54,72,168 hours;Cohort 1 and 2 Artemether80mg/LUM480mg:24,48,68,168 hours

  12. KAF156 and Lumefantrine Area Under Plasma Concentration-time Curve From Time Zero to the Last Measurable Concentration Sampling Time (AUClast)

    AUC is the area under the plasma concentration-time curve. PK parameters were calculated from plasma concentration-time data using non-compartmental methods. The Artemether80mg/LUM480mg arms (standard of care) involved limited pharmacokinetic sampling at 24, 48, 68, and 168 hours following the first dose administration. In contrast, the KAF156 arms had a more extensive sampling, varying by age group, which included time points at 3, 6, 24, 48, 51, 54, 72, and 168 hours following first dose. Due to the limited sampling in the Artemether80mg/LUM480mg arms, it was not planned (per protocol) to calculate AUC values.

    Time frame: Run-in Cohort:Pre-dose,1,3,4,5,6,8,24,25,27,28,29,30,32,48,72,168 hours; Cohort 1 and 2 KAF400mg/LUM480mg-QDx3 6-12 years: 3,6,24,48,51,54,72,168 hours; 6 months -< 6 years: 24,48,51,54,72,168 hours.

  13. KAF156 and Lumefantrine Time to Reach the Maximum Plasma Concentration After Drug Administration (Tmax)

    Tmax is the time to reach maximum plasma concentration following drug administration. PK parameters are calculated from plasma concentration-time data using non-compartmental methods. The Artemether80mg/LUM480mg arms (standard of care) involved limited pharmacokinetic sampling at 24, 48, 68, and 168 hours following the first dose administration. In contrast, the KAF156 arm had a more extensive sampling, varying by age group, which included time points at 3, 6, 24, 48, 51, 54, 72, and 168 hours following first dose. PK samples for the Artemether80mg/LUM480mg arms were collected around the expected Tmax (at 68 hours, i.e., 8 hours after the last dose, based on the known Tmax of lumefantrine in Coartem) to determine Cmax values; in line with the protocol, separate Tmax values were not calculated.

    Time frame: Run-in Cohort:Pre-dose,1,3,4,5,6,8,24,25,27,28,29,30,32,48,72,168 hours; Cohort 1 and 2 KAF400mg/LUM480mg-QDx3 6-12 years: 3,6,24,48,51,54,72,168 hours; 6 months -< 6 years: 24,48,51,54,72,168 hours.

  14. KAF156 and Lumefantrine Plasma Drug Concentration 168 Hours Post First Dose Administration (C168h)

    C168h is the plasma concentration at 168h post first dose administration. PK parameters are calculated from plasma concentration-time data using non-compartmental methods. Analyte KAF156 is not applicable for Artemether80mg/LUM480mg arm.

    Time frame: at 168 hours

Outcome measures

PrimaryPolymerase Chain Reaction (PCR)-Corrected Adequate Clinical and Parasitological Response (ACPR) - Cohorts 1 and 2 Pooled

PCR-corrected ACPR, defined as the absence of parasitemia(PS), was evaluated on Day29. Microscopic species identification was confirmed and determined by PCR genotyping methods to establish malaria recrudescence/reinfection.A participant was considered as PCR corrected ACPR at Day29 if the participant did not meet any of the criteria of early treatment failure (up to Day4), late clinical failure(Day5 to Day29) or late parasitological failure(Day8 to Day29), and had absence of PS on Day29 irrespective of axillary temperature unless the presence of PS after 7days(Day8 or later) was due to reinfection based on PCR genotyping.A presence of PS after 7days of treatment initiation was considered as a reinfection only if the PS was clear before Day8 and none of the parasite strain(s) detected on Day8 or later match with the parasite strain at baseline based on PCR genotyping.Given the age-independent symptoms of acute malaria, and to increase statistical power,the cohorts 1 and 2 were pooled.

PCR-corrected ACPR, defined as the absence of parasitemia, was evaluated. Microscopic species identification was confirmed and determined by polymerase chain reaction (PCR) genotyping methods to establish malaria recrudescence/reinfection. A participant was considered as PCR-corrected ACPR if the participant did not meet any of the criteria of early treatment failure, late clinical failure or late parasitological failure and had absence of parasitemia on Days 15, 29 or 43 irrespective of axillary temperature unless the presence of parasitemia after 7 days was due to reinfection based on PCR. A presence of parasitemia after 7 days of treatment initiation was considered as a reinfection only if the parasitemia was clear before Day 8 and none of the parasite strain(s) detected on Day 8 or later matched with the parasite strain at baseline based on PCR. Given the age-independent symptoms of acute malaria, and to increase statistical power, the cohorts 1 and 2 were pooled (cohort 1/2).
