This is a pilot, double-blind, randomized, parallel-group, placebo-control, exploratory study to evaluate the efficacy and safety of 5-aminolevulinic acid hydrochloride (5-ALA HCl) and sodium ferrous citrate (SFC) added on artemisinin-based combination therapy (ACT) compared with ACT alone in the treatment of malaria. Patients who are suffering from uncomplicated malaria, are eligible for randomization.The study will be conducted in a total of 75 patients with uncomplicated malaria.
Approximately 75 patients will be randomized in a 1:2:2 ratio to 3 arms:
Arm 1: placebo+ACT group (15 patients)
Arm 2: 5 ALA/SFC+Placebo+ACT twice daily (BID) (30 patients)
Arm 3: 5-ALA/SFC+Placebo+ACT once daily (QD) (30 patients)
The study duration will be a maximum of 98 days with treatment period of 7 days and follow-up period of 91 days.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Placebo + ACT | Placebo Comparator | Patients will receive placebo for Day 1 to Day 7 and ACT (as per package instruction) for Day 1 to Day 3. |
|
| 5 ALA/SFC+placebo+ACT BID | Experimental | 5-ALA HCl 300 mg and SFC 236 mg will be administered BID for Day 1 to Day 7 and ACT (as per package instruction) for Day 1 to Day 3. Patients will receive 5-ALA HCl+Placebo and SFC+Placebo at odd number of study medication dosing (Dose 1, 3, 5, 7, 9, 11, 13) and only 5-ALA HCl and SFC at even numbers of study medication dosing (Dose 2, 4, 6, 8, 10,12, 14). |
|
| 5-ALA/SFC+placebo+ACT QD | Experimental | 5-ALA HCl 600 mg and SFC 472 mg will be administered QD in the morning or evening for Day 1 to Day 7 and ACT (as per package instruction) for Day 1 to Day 3. Patients will receive 5-ALA HCl and SFC at odd number of study medication dosing (Dose 1, 3, 5, 7) and placebo at even numbers of study medication dosing (Dose 2, 4, 6). |

| Measure | Description | Time Frame |
|---|---|---|
| Number of patients with adverse events | Number of patients with any adverse events or clinically significant abnormal laboratory parameters to investigate safety and tolerability of 5-ALA HCl and SFC in simultaneous administration with ACT. | From screening visit (Day -1) untill the Follow-up Visit (Day 98) |
| Cure rate on Day 28 | Cure rate is defined as the proportion of patients with polymerase chain reaction (PCR)-corrected Adequate Clinical and Parasitological Response (ACPR). PCR-corrected ACPR is defined as patients with clearance of asexual parasites within 28 days of initiation of study medication and without recrudescence within 28 days. Cure rate to investigate the preliminary efficacy of 5-ALA HCl and SFC in simultaneous administration with ACT. | Day 28 |
| Parasite Clearance Time | Time from first dosing to time of first of 4 consecutive readings with zero parasite count in blood. Calculated based on parasite count in blood every 4 hours after the start of study medication for 72 hours until there are 4 consecutive negative readings. | Every 4 hours for 72 hours from Day 1 to Day 7 until 4 consecutive negative readings |
| Fever Reduction Time | Time to Fever Reduction is defined as the time from first dosing to first normal reading of temperature (<37.5 °C) for two consecutive normal temperature reading plus confirmed normal temperature every 4 hours after the start of study medication for 72 hours | Every 4 hours for 72 hours from Day 1 to Day 7 |
| Gametocyte Clearance Time | Time from the first dose until first total and continued disappearance of gametocytes which remains at least a further 24 hours | Day 1 to Day 7 + 24 hours |
