Polypill Versus Metformin in New Onset Type 2 Diabetes (PiVOT)

April 24, 2024 updated by: George Medicines PTY Limited

Polypill Versus Metformin in New Onset Type 2 Diabetes: a Low Dose Triple Therapy Polypill Versus Metformin for Glycaemic Control in Newly Diagnosed Type 2 Diabetes

The goal of this clinical trial is to learn about the effect of the GMRx-4 IR polypill compared to metformin monotherapy on glycosylated haemoglobin (HbA1c) when used as first line therapy in adults with recently diagnosed Type 2 Diabetes. The main question it aims to answer is:

That the GMRx-4 IR polypill, compared to metformin, will improve glucose lowering in those with recently diagnosed Type 2 Diabetes.

Participants will be required to take either:

One capsule of the GMRx-4 IR polypill each morning and one 175mg metformin capsule each evening for 16 weeks.

Or One metformin 500mg capsule each morning and each evening for 16 weeks.

Participants will not know which of the two treatment regimens they will be taking. Participants will be provided with the necessary guidance information, equipment, online support and telephone/video calls from trained members of the study team to complete the study procedures at home although some support from a Healthcare Professional either at home or at a clinic will be offered if needed. The study will involve participants completing the following information and procedures and reporting electronically:

Medical History (conditions and treatments) Gender Age Ethnicity/Race Weight Height Blood Pressure Heart Rate Blood collection for measurement of HbA1c (average blood glucose levels over a period of time), fasting glucose, creatinine and estimated glomerular filtration rate (eGFR) for kidney function, cholesterol, pregnancy (if not measured in a urine sample) Urine pregnancy test in women of child-bearing potential Concomitant Medications taken Safety outcomes Tolerability to the study treatment Adherence with taking the study treatment The number of any unused study treatment capsules

Description

Inclusion Criteria:

  1. Aged ≥18 years;
  2. Diagnosis of Type 2 Diabetes (T2D) within 24 months;
  3. Drug naïve or using metformin monotherapy at ≤1g daily;
  4. Body mass index between 18.5 and 45 kg/m2;
  5. HbA1c ≥6.0% (metformin monotherapy) or ≥6.5% (drug naïve), and ≤12%;
  6. eGFR ≥45 ml/min/1.73m2;
  7. Signed informed consent; and
  8. Willingness to take a pregnancy test prior to starting treatment (participants of childbearing potential).

Exclusion Criteria:

  1. There is a definite contraindication to either metformin, SGLT2 inhibitors or Dipeptidyl-peptidase 4 (DPP4) inhibitors;
  2. There is a definite indication for an SGLT2 inhibitor;
  3. A known situation where medication might be altered for a significant length of time (e.g., planned surgery);
  4. Moderate or severe anaemia (Hb< 100g/L women and <110g/L in men), haemolytic anaemia or known haemoglobinopathy (which may affect the accurate measurement of HbA1c);
  5. Unlikely to complete the trial, adhere to the trial or complete study contacts, including at-home pathology tests, according to investigator judgement; or
  6. Known or suspected pregnancy or breast-feeding;
  7. Participants of childbearing potential (participants who are anatomically and physiologically capable of becoming pregnant), or have a partner of childbearing potential, not willing to use highly effective contraceptive for the 16-week duration of the trial, and who do not confirm a negative pregnancy test before starting the drug;
  8. Any severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgement of the Investigator, and in discussion with the Medical Monitor, would make the participant inappropriate for entry into this study.

  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Quadruple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Metformin IR 500mg in the morning and at night
One metformin IR 500mg capsule in the morning and at night. Capsules are taken with, or just after, food, and swallowed whole with water. Capsules will be taken at, or as close as possible to, the same time of morning and the same time of evening each day for 16 weeks.
As described previously - Experimental Arm, 175mg at night
As described previously - Active Comparator Arm, 500mg in the morning and 500mg at night
Experimental: GMRx-4 IR polypill in the morning and metformin Immediate Release (IR)175mg at night
One GMRx-4 IR polypill capsule (metformin IR 175mg + dapagliflozin 2.5mg + sitagliptin 17.5mg) in the morning and one metformin IR 175mg capsule at night. Capsules are taken with, or just after, food, and swallowed whole with water. Capsules will be taken at, or as close as possible to, the same time of morning (GMRx-4 IR) and the same time of evening (metformin 175mg) each day for 16 weeks.
As described previously - Experimental Arm, 175mg at night
As described previously - Active Comparator Arm, 500mg in the morning and 500mg at night
