Blue: Important conclusions

Highlight ( Page 7)

Over 28 days, INV-202 (25 mg daily) was well tolerated, with no reported serious adverse events (SAEs) or severe TEAEs. A signal for rapid weight loss was observed with improvements in several markers of cardiometabolic risk. INV-202 systemic PK exposure was as expected.

Yellow: Interesting

28-day repeat-dose (INV-202 [25 mg] or placebo, once-daily oral tablet), parallel-group study in 37 participants aged 18 to 65 years (46% female, mean age 55 years, glycated haemoglobin 5.7% [39 mmol/mol], body mass index [BMI] 38.1 kg/m2) with features of metabolic syndrome and glucose intolerance.

Participants were randomly assigned (1:1) to INV-202 (1 25 mg tablet) or placebo (1 tablet) taken orally, once daily with food

Highlight ( Page 2)

Administration INV-202 with food (standard meal) is recommended to reduce the incidence of gastrointestinal adverse effects and to improve tolerance

Highlight ( Page 3)

INV-202 was well tolerated over 28 days of treatment,

Highlight ( Page 4)

The most common TEAEs were related to the known effects of CB1R blockade in the gastrointestinal (GI) tract, namely, increased GI motility (nausea, diarrhoea), abdominal discomfort, and decreased appetite

Highlight ( Page 4)

Participants treated with INV-202 showed decreasing trends in mean weight and mean waist circumference

There were favourable trends for HbA1c

Highlight ( Page 6)

Mild accumulation of both analytes (INV-202 and DA-INV-202) was observed following daily INV-202 doses over 28 days, with increased mean Ctrough from D8 to D29 (24 hours post-dose; Figure 2).

EAEs of special interest (depression, anxiety, irritability, and insomnia) were experienced by four participants (20%; INV-202), of which one experienced three events (insomnia, depressed mood, irritability). However, three of these participants had pre-existing related conditions including mood disorder, depression and insomnia, and two were menopausal with a history of related insomnia. One participant on placebo reported anxiety
