Detaljerad miljöinformation

1. Predicted Environmental Concentration (PEC):

The Predicted Environmental Concentration is calculated using the following formula:

PEC (µg/L)


A x 109 x (100-R) / 365 x P x V x D x 100



A (kg/year)


45.8346 (total sold amount API in the most recent sales data for Sweden (2018) was distributed by IQVIA in 2019)

R (%)


removal rate (due to loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation)



0% (worst-case scenario: no removal)



number of inhabitants in Sweden (9 x 106)

V (L/day)


volume of waste water per capita and day



200 (ECHA default) [9]



factor for dilution of waste water by surface water flow



10 (ECHA default) [9]

PEC (µg/L)


0.00697635 µg/L


2.1. Ecotoxicological studies

2.1.1. Algae

Algal growth inhibition test with the green alga (Pseudokirchneriella subcapitata) (OECD 201) [1]:

EγC50 72 h (biomass) = 1.02 mg/L

NOECγ (biomass) = 0.0370 mg/L

ErC50 72 h (growth rate) = 4.16 mg/L

NOECr (growth rate) = 0.129 mg/L

2.1.2. Crustacean


Reproduction test with water-flea (Daphnia magna) (OECD 211) [2]:

NOEC 21 days (reproduction) = 47.9 µg/L

2.1.3. Fish


Fish early life stage test with fathead minnow (Pimephales promelas) (OECD 210) [3]:

NOEC 28 days (mortality) = 15.5 µg/L

2.1.4. Other ecotoxicity data

Activated sludge respiration inhibition test (OECD 209) [4]

EC50 3h (respiration inhibition) > 1000 mg/L

NOEC 3h = 1000 mg/L

2.2. Calculation of Predicted No Effect Concentration (PNEC)

PNEC (µg/l) = lowest NOEC/10, where 10 is the assessment factor used. NOEC for fish 15.5 µg/L has been used for this calculation since it is the most sensitive of the three tested species.

PNEC = 15.5 µg/L/10 = 1.55 µg/L

2.3. Environmental risk classification (PEC/PNEC ratio)

PEC/PNEC = 0.00697635/1.55 = 0.004500869 i.e. PEC/PNEC ≤ 0.1

Conclusion for environmental risk:

Use of ibrutinib has been considered to result in insignificant environmental risk.


3.1. Biotic degradation

3.1.1. Ready biodegradation

Ibrutinib was investigated for its ready biodegradation in a 28-day manometric respirometry test according to OECD 301F [5]:

Result: Not readily biodegradable.

3.1.2. Simulation study Aerobic degradation in aquatic sediment systems:

Ibrutinib was investigated for its aerobic degradation in a 100-day aquatic sediment test, according to OECD 308 [6]:

The fate of ibrutinib has been studied in two natural aquatic sediment systems (Swiss Lake and Calwich Abbey Lake) under laboratory conditions.

In Calwich Abbey Lake aquatic sediment, the total radioactivity in the water layer declined from a mean of 90.1% of the applied radioactivity at time zero to 2.2% after 100 days. In the sediment, there was a corresponding increase in the total radioactivity to a mean of 84.1% of the applied radioactivity at 100 days. The proportion of radioactivity remaining unextracted in the sediment increased to a mean of 47.7% of the applied radioactivity after 100 days.

Dissipation of radioactivity followed a similar pattern in the Swiss Lake aquatic sediment. The total radioactivity in the water layer declined from a mean of 91.1% of the applied radioactivity at time zero to 6.3% after 100 days. In the sediment, total radioactivity increased to a mean of 79.6% of the applied radioactivity at 100 days. The proportion of radioactivity remaining unextracted in the sediment increased to a mean of 54.9% of the applied radioactivity after 100 days.

In both aquatic sediments, evolution of volatile radioactivity was minimal, up to a mean of 4.0 and 2.8% of the applied radioactivity after 100 days, from the Calwich Abbey Lake and Swiss Lake system, respectively. Non-extractable radioactivity in the Calwich Abbey Lake and Swiss Lake sediment was mainly associated with the humin fractions.

DT50 and DT90 values for the decline of ibrutinib from the water, the sediment and from the total aquatic sediment system are shown below:

Conclusion for degradation:

Ibrutinib is slowly degraded in the environment.


4.1. Partition coefficient octanol/water

The partition coefficient octanol/water was determined using the shake flask method (OECD 107). [7]

The log Kow was determined at pH 4.0, 7.0 and 9.0.
Log Kow = 3.8 (pH 4.0)

Log Kow = 4.0 (pH 7.0)

Log Kow = 4.0 (pH 9.0)

4.2. Bioconcentration

The bioconcentration and depuration characteristics of ibrutinib in the rainbow trout in a flow through system were examined according to OECD 305 [8].

BCFlow dose = 13.5

BCFhigh dose = 68.0

Ibrutinib is not expected to bioaccumulate in fish.

Conclusion for bioaccumulation:

Ibrutinib has low potential for bioaccumulation.



Results for ibrutinib


DT50 freshwater > 40 days or

DT50 sediment > 120 days

DT50 freshwater = 4.6 – 9.5 days

DT50 total system = 38 - 41 days


BCF > 2000

BCF = 68.0 (high dose)

BCF = 13.5 (low dose)


Chronic NOEC < 10 µg/L or

CMR or endocrine disrupting

NOECalgae = 4.16 mg/L

NOECdaphnia = 47.9 µg/L

NOECfish = 15.5 µg/L

None of the PBT-criteria are fulfilled. Therefore, ibrutinib is not considered a PBT-substance
